		Phenotypic plasticity of Escherichia Coli upon exposure to physical stress induced by ZnO nanorods Evolution of bacteria to selective chemical pressure (e.g. antibiotics) is well studied in contrast to the influence of physical stressors. Here we show that instantaneous physical stress in a homogeneous environment (without concentration gradient) induces fast adaptation of Escherichia coli. We exposed E. coli to a large number of collisions of around 10(5) per bacterium per second with sharp ZnO nanorods. The pressure exerted on the bacterial cell wall was up to 10 GPa and induced phenotype changes. The bacteria's shape became more spherical, the density of their periplasm increased by around 15% and the average thickness of the cell wall by 30%. Such E. coli cells appeared almost as Gram-positive bacteria in the standard Gram staining. Additionally, we observed a combination of changes occurring at the genomic level (mutations identified in form of single nucleotide polymorphisms) and downregulation of expression of 61 genes encoding proteins involved in beta-oxidation of fatty acids, glycolysis, the citric acid cycle, as well as uptake of amino acids and enzyme cofactors. Thus, we show that bacteria undergo phenotypic changes upon instantaneous, acute physical stress without any obviously available time for gradual adaptation.

		Nano-multilayered coatings of (TiAlSiY)N/MeN (Me=Mo, Cr and Zr): Influence of composition of the alternating layer on their structural and mechanical properties Multilayered design showed itself to advantage for improvement of functional nitride coatings, which are widely required in various industry applications. This article reports on deposition and detailed characterization series of combined nano-multilayered coatings based on (TiAISiY)N with changes in components of alternating binary layers. Vacuum-arc deposited (TiAlSiY)N/MoN, (TiAlSiY)N/CrN and (TiAlSiY)N/ZrN coatings were analyzed by means of various experimental techniques such as SEM with EDS, XRD and GIXRD, SIMS, XPS and Raman spectroscopy. Microstructure of (TiAlSiY)N/MoN coating was characterized by creation of fine-grained fcc-AITiN phase of (200) plane with congruent growth of gamma-Mo2N (200) due to high isostruturality of lattices of alternating layers. The formation of fcc-AIYTiN phase of (111) plane and fcc-TiCrN phase of (200) plane were observed in multilayered (TiAlSiY)N/CrN coating and referred to the loss of clear interfaces and the formation of transition layers due to the diffusion of Ti atoms. Nano-multilayered (TiAlSiY)N/ZrN system showed the formation of stoichiometric fcc compounds of TiN with (200) plane and ZrN with (111) plane, respectively. The evaluation of mechanical properties as nanohardness, reduced elastic modulus, elastic strain prior to failure, and resistance to plastic deformation measurements was performed. The presented results showed important information about the physical and mechanical properties of new nano-multilayered systems for their subsequent application, as well as improvement of existing achievements.

		Gel with silver and ultrasmall iron oxide nanoparticles produced with Amanita muscaria extract: physicochemical characterization, microstructure analysis and anticancer properties Combination therapy remains one of the most promising and intensively developed direction incancer treatment. This study is aimed to combine and investigate the anticancer properties of silver nanoparticles (NPs) and Amanita muscaria mushroom in gel formulation. For this, hyaluronic acid was used as gel-forming agent, whereas Amanita muscaria extract was used as capping agent during silver and ultrasmall iron oxide (MAg) NPs synthesis. Amanita muscaria compounds formed NP's surface layer and contributed anticancer properties, whereas silver NPs contributed anticancer, fluorescence and photoactive properties to the gel. Physicochemical characterization included X-ray diffraction (XRD), microscopies (SEM, cryo-SEM, TEM, confocal fluorescence), spectrofluorometric method, thermogravimetric analysis (TGA), dynamic light scattering (DLS) techniques, energy dispersive (EDS), Fourier transform infrared (FTIR) and ultraviolet-visible (UV-Vis) spectroscopies, zeta-potential and rheological measurements. Microstructure analysis of hyaluronic acid/MAg NPs gel was performed by cryo-SEM technique. We showed that hyaluronic acid is a perfect gel-forming agent from both biomedical and technological points of view. It is well-mixed with MAg NPs forming stable gel formulation; high homogeneity of hyaluronic acid/MAg NPs gel was shown by SEM EDS elemental mapping. Microstructure of the gel was found to be highly ordered and consisted of domains from perforated parallel tubular structures. This finding expanded our understanding of gels and broke the stereotype of gel structure as chaotic network of fibers. Cytotoxicity studies performed on 2D and 3D HeLa cell cultures pointed to a high potential of hyaluronic acid/MAg NPs gel for local treatment of cancer. Cell response was found to be significantly different for 2D and 3D cell cultures that was related to their different cytoarhitecture and gene expression. Thus, the results of the cellular spheroids viability showed that they were significantly more resistant to the cytotoxic action of MAg NPs and their gel formulation than 2D cell culture. Hyaluronic acid used as gelling agent in gel formulation was found to increase an effectiveness of active components (MAg NPs, Amanita muscaria extract) probably improving their transport inside HeLa spheroids.

		Silver and ultrasmall iron oxides nanoparticles in hydrocolloids: effect of magnetic field and temperature on self-organization Micro/nanostructures, which are assembled from various nanosized building blocks are of great scientific interests due to their combined features in the micro- and nanometer scale. This study for the first time demonstrates that ultrasmall superparamagnetic iron oxide nanoparticles can change the microstructure of their hydrocolloids under the action of external magnetic field. We aimed also at the establishment of the physiological temperature (39°C) influence on the self-organization of silver and ultrasmall iron oxides nanoparticles (NPs) in hydrocolloids. Consequences of such induced changes were further investigated in terms of their potential effect on the biological activity in vitro. Physicochemical characterization included X-ray diffraction (XRD), optical microscopies (SEM, cryo-SEM, TEM, fluorescence), dynamic light scattering (DLS) techniques, energy dispersive (EDS), Fourier transform infrared (FTIR) and ultraviolet-visible (UV-Vis) spectroscopies, zeta-potential and magnetic measurements. The results showed that magnetic field affected the hydrocolloids microstructure uniformity, fluorescence properties and photodynamic activity. Likewise, increased temperature caused changes in NPs hydrodynamic size distribution and in hydrocolloids microstructure. Magnetic field significantly improved photodynamic activity that was attributed to enhanced generation of reactive oxygen species due to reorganization of the microstructure.

	Abstrakt lub materiały konferencyjne, albo abstrakt publikacji z dodatkowymi numerami DOI	Selected polycationic surfactants as siRNA carriers for gene therapy So far many drug delivery systems for transfer of nucleic acids in gene therapy have been proposed but there is no universal system for transfer of genetic material into cells. The largest problem in the design of new nucleic acids delivery vehicles is finding a carrier which fulfill such criteria as: stability in complexes with nucleic acids, non-toxicity, non-immunogenicity, ability to safe degradation and easy preparation protocol. A certain group of polycationic surfactants are able to meet these requirements. Their amphiphilic nature, structure flexibility and the ability to bind to siRNA or DNA oligomers are just some of the advantages. Our past research on selected dicationic compounds as DNA or siRNA delivery systems, indicated that an increase in the number of surfactant subunits is a promised direction to develop new efficient carriers of short nucleic acids. In this work we present results of the studies of the complexes based on selected novel polycationic surfactants (eg. oligomeric imidazolium derivatives) with a model system - double stranded 21-bp siRNA oligomer. By the use of biophysical methods (electrophoresis, circular dichroism, small angle scattering of synchtorton radiation and cryo-transmission electron microscopy) we examined their complexation capacity, nanostructure of lipoplexes, conformational changes in bound siRNA oligomers and micromorphology of complexes. Our studies have shown the formation of stable systems with promising transfection properties. These systems exhibit various morphologies in frozen state.

		ZnS coating for enhanced environmental stability and improved properties of ZnO thin films Low environmental stability of ZnO nanostructures in hydrophilic systems is a crucial factor limiting their practical applications. ZnO nanomaterials need surface passivation with different water-insoluble compounds. This study describes a one-step passivation process of polycrystalline ZnO films with ZnS as a facile method of ZnO surface coating. A simple sulfidation reaction was carried out in gas-phase H2S and it resulted in formation of a ZnS thin layer on the ZnO surface. The ZnS layer not only inhibited the ZnO dissolving process in water but additionally improved its mechanical and electrical properties. After the passivation process, ZnO/ZnS films remained stable in water for over seven days. The electrical conductivity of the ZnO films increased about 500-fold as a result of surface defect passivation and the removal of oxygen molecules which can trap free carriers. The nanohardness and Young's modulus of the samples increased about 64% and 14%, respectively after the ZnS coating formation. Nanowear tests performed using nanoindentation methods revealed reduced values of surface displacements for the ZnO/ZnS system. Moreover, both ZnO and ZnO/ZnS films showed antimicrobial properties against Escherichia coli.

		Self-organizing silver and ultrasmall iron oxide nanoparticles prepared with ginger rhizome extract: Characterization, biomedical potential and microstructure analysis of hydrocolloids Multimodal nanoparticles (NPs) that may be used for therapies and diagnostics is the most promising trend for efficient therapy. We demonstrate that nanocomposite based on self-organizing silver and ultrasmall magnetic iron oxide NPs (MAg) produced in one-step synthesis revealed unique combination of fluorescence, bactericidal, fungicidal properties and have a potential as magnetic resonance imaging (MRI) contrast agent. Using the green chemistry approach, ginger (Zingiber officinale) rhizome extract was applied as capping agent for MAg synthesis, providing also additional fluorescent properties of NPs and inducing hydrocolloids structuring. The MAg were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive microanalysis (EDS), fluorescence microscopy, cryo-SEM, dynamic light scattering (DLS) techniques, Fourier transforminfrared (FTIR) and ultraviolet-visible (UV-Vis) spectroscopies. MAg dispersions in water and some biological media are very stable which is important for biomedical application. The existence of microstructure inMAg hydrocolloids was proved. The hierarchical character and high ordering of this microstructure were discovered and its level-by-level building blocks were investigated. The microstructure was found to be responsible for fluorescence emittance of MAg hydrocolloids. The properties as well as potential application of the MAg hydrocolloids is yet to be discovered. © 2017 Elsevier Ltd. All rights reserved.

		Release and cytotoxicity studies of magnetite/Ag/antibiotic nanoparticles: An interdependent relationship Though the cytotoxic properties of magnetite nanoparticles (NPs) are rather well investigated and known to be dose dependent and rather low, surface functionalization can drastically change their properties. To determine whether the cytotoxicity of magnetite/Ag/antibiotic NPs may be associated, among other things, with iron, silver and antibiotic release, this study investigates the release profiles and cytotoxicity of magnetite/Ag/rifampicin and magnetite/Ag/doxycycline NPs compares it similar profiles from magnetite, magnetite/Ag NPs and antibiotics. It was established that the studied NPs released not only water-soluble substances, such as antibiotics, but also poorly-soluble ones, such as iron and silver. The deposition of silver on the magnetite surface promotes the release of iron by the formation of a galvanic couple. Antibiotic adsorbed on the magnetite/Ag surface plays a dual role in the galvanic corrosion processes: as a corrosion inhibitor for iron oxides and as a corrosion promoter for silver. Magnetite/Ag/rifampicin and magnetite/Ag/doxycycline. NPs were found to have greater cytotoxicity towards the HEK293T cell line than magnetite NPs. These results were attributed to the combined toxic action of the released iron, silver ions and antibiotics. Intensive and simultaneous release of the NP components caused cell stress and suppressed their growth.

		Green synthesis of rifampicin-loaded copper nanoparticles with enhanced antimicrobial activity The antimicrobial properties of copper and rifampicin-loaded copper nanoparticles were investigated using four strains: Staphylococcus aureus, Escherichia coli, Bacillus pumilis and Pseudomonas fluorescens. Spherical-shaped copper nanoparticles were synthesized via green reduction method from the peppermint extract. It was found that adsorption of rifampicin on the copper nanosurface enhances its biological activity and prevents the development of resistance. The interactions between rifampicin-copper nanoparticles and bacteria cells were monitored using atomic force microscopy (AFM) and confocal laser scanning microscopy (CLSM). It was proven that loaded with rifampicin copper nanoparticles were able to damage the S. aureus cell membrane and facilitate the bacteria biofilm matrix disintegration. Moreover, the DNA decomposition of S. aureus treated with copper and rifampicin-copper nanoparticles was confirmed by agarose gel electrophoresis. The results obtained indicate that adsorption of rifampicin on the copper nanoparticles surface might provide the reduction of antibiotic dosage and prevent its adverse side effects.

		Influence of silver content on rifampicin adsorptivity for magnetite/Ag/rifampicin nanoparticles Magnetite nanoparticles (NPs) decorated with silver (magnetite/Ag) are intensively investigated due to their application in the biomedical field. We demonstrate that the increase of silver content on the surface of nanoparticles improves the adsorptivity of antibiotic rifampicin as well as antibacterial properties. The use of ginger extract allowed to improve the silver nucleation on the magnetite surface that resulted in an increase of silver content. Physicochemical and functional characterization of magnetite/Ag NPs was performed. Our results show that 5%-10% of silver content in magnetite/Ag NPs is already sufficient for antimicrobial properties against Streptococcus salivarius and Staphylococcus aureus. The rifampicin molecules on the magnetite/Ag NPs surface made the spectrum of antimicrobial activity wider. Cytotoxicity evaluation of the magnetite/Ag/rifampicin NPs showed no harmful action towards normal human fibroblasts, whereas the effect on human embryonic kidney cell viability was time and dose dependent.

		Effect of ion implantation on the physical and mechanical properties of Ti-Si-N multifunctional coatings for biomedical applications In the present work, multifunctional Ti-Si-N coatings have been deposited using CAVD method with the aim of studying their chemical, physical, structural and mechanical properties. Coatings of Ti-Si-N were modified by high-intensity ion implantation using copper ions with dose D = 2 x 10(17) ions/cm(2) and energy E = 60 keV. The results demonstrated that ion implantation has an effect on the grain size, hardness, and Young modulus of the Ti-Si-N coating. Additionally, the effect of Cu implantation on the bioactive properties of coatings was investigated by contact antimicrobial essay. The results show a high release of Cu ions in the cultivation liquid and the low efficiency of the <20% Cu doping towards E. coli bacteria. Our results bring understanding to the low dosage ion implantation of multifunctional surfaces towards applications and general drawbacks of ion implantation as bioactive tailoring method.

		High temperature behavior of functional TiAlBSiN nanocomposite coatings This article reports on the thorough characterization of structural-phase transformation in amorphous TiAlBSiN coating after high temperature annealing at 900 degrees C in ambient air. The influence of annealing on the tribo mechanical behavior of the coating at nano and micro scale was also examined. The research included multiple experimental techniques, i.e. AFM, SEM, TEM, HR-TEM, EDS, XPS and Raman spectroscopy. Experiments showed that the amorphous phase of the TiAlBSiN coating undergoes a structural transformation, evidenced in the changes of parameters such as topological and chemical short-range order after the post-deposition annealing at 900 degrees C in air. The observed structural transformation, leads to a phase separation with the formation of a three dimensional nc-TiAl3/a-SiBN(O) nanocomposite structure. The relative increase of hardness, reduced elastic modulus, H/Er ratio and H-2/E-r(3) ratio after high temperature treatment of TiAlBSiN coatings is also reported. The complex interdependency between chemistry, morphology and relative composition of the amorphous TiAlBSiN coating phase, during the high temperature treatment, with the respective change of the tribo-mechanical characteristics, are evidence of the improvement of the coating properties in response to the environmental conditions and high temperature. This work contributes particularly to the development and understanding of flexible nanocomposite protective coatings and their changes at high temperature of operation.

		iRGD peptide as effective transporter of CuInZnxS2+x quantum dots into human cancer cells In this paper, iRGD peptide-mediated quantum dots (QDs) delivery was studied. In the first step, dodecanethiol-capped CulnZn(x)S(2+x) (ZCIS) QDs were prepared and subsequently transferred into water using a standard and facile ligand exchange approach involving 3-mercaptopropionic acid (MPA). ZCIS@MPA nanocrystals possess a photoluminescence quantum yield (PL QY) of 25%, a PL emission centered at ca. 640nm and low distributions in size and shape. Next, the iRGD peptide was electrostatically associated to ZCIS@MPA QDs. After cytotoxicity evaluation, the tumor-targeting and penetrating activities of the iRGD/QD assembly were investigated by confocal microscopy. The experiments performed on various cancer cell lines revealed a high penetration ability of the assembly, while the bare QDs were not internalized. Additionally, imaging experiments were conducted on three-dimensional multicellular tumor spheroids in order to mimic the tumor microenvironment in vivo. iRGD/QD assemblies were found to be evenly distributed throughout the whole HeLa spheroid contrary to normal cells where they were not present. Therefore, iRGD/QD assemblies have a great potential to be used as targeted imaging agents and/or nanocarriers specific to cancer cells.

		Copper-gold nanoparticles: Fabrication, characteristic and application as drug carriers In this investigation, the fabrication of porous core/shell nanostructures consisting of copper (core) and copper-gold nanoalloy (shell) for medical applications is presented. As a core triangular-shaped copper nanoparticles were used. The porous bimetallic nanoshell was prepared via galvanic reaction in the presence of oil-in water emulsion. It was proved that porous nanoalloy layer can be prepared at pH 7 and in the presence 0.1% and 0.5% oil-in water emulsion. The porous structure fabrication was mainly determined by volume fraction of hexadecane to acetone in the oil-in water emulsion and Zeta-potential of emulsion droplets (pH of emulsion). The influence of emulsion droplets size before galvanic reaction on porous structure preparation was negligible. It was found that doxorubicin could be easily introduced and released from porous core/shell nanostructures, due to spontaneous adsorption on the copper-gold nanoporous surface. The in vitro test showed that cytotoxic effect was more prominent once the doxorubicin was adsorbed on the porous copper-gold nanocarriers. It was demonstrated, that doxorubicin-loaded copper-gold nanostructures caused inhibition cell proliferation and viability of cancer cells, in a concentration-dependent manner. The results indicates that presented toper-gold nanocarrier have potential to be used in targeted cancer therapy, due to its porous structure and cytotoxic effect in cancer cells.

		Fourier transform infrared and Raman spectroscopy studies on magnetite/Ag/antibiotic nanocomposites This article presents a study on the detection of antibiotics in magnetite/Ag/antibiotic nanocomposites using Fourier transform infrared (FTIR) and Raman spectroscopy. Antibiotics with different spectra of antimicrobial activities, including rifampicin, doxycycline, cefotaxime, and ceftriaxone, were studied. Mechanical mixtures of antibiotics and magnetite/Ag nanocomposites, as well as antibiotics and magnetite nanopowder, were investigated in order to identify the origin of FTIR bands. FTIR spectroscopy was found to be an appropriate technique for this task. The spectra of the magnetite/Ag/antibiotic nanocomposites exhibited very weak (for doxycycline, cefotaxime, and ceftriaxone) or even no (for rifampicin) antibiotic bands. This FTIR “invisibility” of antibiotics is ascribed to their adsorbed state. FTIR and Raman measurements show altered C—O, C=O, and C—S bonds, indicating adsorption of the antibiotic molecules on the magnetite/Ag nanocomposite structure. In addition, a potential mechanism through which antibiotic molecules interact with magnetite/Ag nanoparticle surfaces is proposed. © 2015 Elsevier B.V. All rights reserved.

		Synthesis, structure, EPR studies and up-conversion luminescence of ZnO:Er3+-Yb3+@Gd2O3 nanostructures ZnO:Er3+-Yb3+@Gd2O3 nanostructures were obtained by "wet" chemistry methods - the sol-gel technique for the preparation of ZnO and ZnO:Er3+-Yb3+ nanoparticles (NPs), and the seed deposition method for obtaining Gd2O3. The crystal structure, morphology, phase and elemental composition, resonant microwave absorption of rare earth ions, point defects in the ZnO:Er3+-Yb3+@Gd2O3 crystal structure and up-conversion luminescence were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive X-ray (EDX), X-ray photoelectron spectroscopy (XPS), electron paramagnetic resonance (EPR) spectroscopy, and optical spectroscopy. The crystallization temperature (600 degrees C) of the Gd2O3 phase on the ZnO surface was found. As-obtained ZnO:Er3+-Yb3+ NPs (with size similar to 7 nm) are highly crystalline and monodispersed. ZnO:Er3+-Yb3+ NPs annealing at 900 degrees C leads to the formation of highly polydispersed ZnO:Er3+-Yb3+ NPs, covered by a Gd2O3 shell. The process of the incorporation of the rare earth ions into the ZnO structure, as well as the effect of Gd2O3 content on the morphology and visible up-conversion (UC) luminescence in ZnO:Er3+-Yb3+ matrices were studied.

		Synthesis and characterization of magnetite/silver/antibiotic nanocomposites for targeted antimicrobial therapy The article is devoted to preparation and characterization of magnetite/silver/antibiotic nanocomposites for targeted antimicrobial therapy. Magnetite nanopowder was produced by thermochemical technique; silver was deposited on the magnetite nanoparticles in the form of silver clusters. Magnetite/silver nanocomposite was investigated by XRD, SEM, TEM, AFM, XPS, EDX techniques. Adsorptivity of magnetite/silver nanocomposite towards seven antibiotics from five different groups was investigated. It was shown that rifampicin, doxycycline, ceftriaxone, cefotaxime and doxycycline may be attached by physical adsorption to magnetite/silver nanocomposite. Electrostatic surfaces of antibiotics were modeled and possible mechanism of antibiotic attachment is considered in this article. Raman spectra of magnetite, magnetite/silver and magnetite/silver/antibiotic were collected. It was found that it is difficult to detect the bands related to antibiotics in the magnetite/silver/antibiotic nanocomposite spectra due to their overlap by the broad carbon bands of magnetite nanopowder. Magnetic measurements revealed that magnetic saturation of the magnetite/silver/antibiotic nanocomposites decreased on 6-19% in comparison with initial magnetite nanopowder. Pilot study of antimicrobial properties of the magnetite/silver/antibiotic nanocomposites were performed towards Bacillus pumilus. © 2015 Elsevier B.V. All rights reserved.

		Atomic layer deposition TiO2 coated porous silicon surface: Structural characterization and morphological features TiO2 thin films were grown on highly-doped p-Si (100) macro- and mesoporous structures by atomic layer deposition (ALD) using TiCl4 and deionized water as precursors at 300 °C. The crystalline structure, chemical composition, and morphology of the deposited films and initial silicon nanostructures were investigated by scanning electron microscopy, transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, micro-Raman spectroscopy and X-ray diffraction (XRD). The mean size of TiO2 crystallites was determined by TEM, XRD and Raman spectroscopy. It was shown that the mean crystallite size and the crystallinity of the TiO2 are influenced dramatically by the morphology of the porous silicon, with the mesoporous silicon resulting in a much finer grain size and amorphous structure than the macroporous silicon having a partially crystal anatase phase. A simple model of the ALD layer growth inside the pores was presented.

		Experimental and solid-state computational study of structural and dynamic properties in the equilibrium form of temazepam Structural properties and rotational dynamics of methyl groups in the most stable form of temazepam were investigated by means of C-13 CP MAS NMR, quasielastic neutron scattering (QENS), and H-1 NMR spin lattice relaxation methods. The QENS and H-1 NMR studies reveal the inequivalency of methyl groups, delivering their activation parameters. The structural properties of the system were explored in frame of periodic density functional theory (DFT) computations, giving insight into the reorientational barriers and providing understanding of the solid-state NMR results. The theoretical computations are shedding light on the intermolecular interactions along their relation with particular asymmetric structural units.

		A study of out-of-plane cation dynamics in a bis-thiourea pyridinium chloride inclusion compound The out-of-plane motion of the pyridinium cation in the bis-thiourea pyridinium chloride inclusion compound has been studied in a wide temperature range using (1)H NMR, dielectric spectroscopy and quasielastic neutron scattering. The geometry of this motion is obtained from the Q-dependence of the elastic incoherent structure factor determined from the quasielastic neutron scattering measurements. We find that the pyridinium cation performs out-of-plane reorientations around the axis passing through two opposite atoms of the ring. The correlation times as a function of temperature were measured in the three known crystallographic phases, finding a good agreement between the three techniques employed. The activation energy for this motion changes from 5 ± 1 kJ mol(-1) in the low-temperature phase to 1.2 ± 0.2 kJ mol(-1) in the intermediate and high-temperature phases.

		A hybrid method for estimation of molecular dynamics of diazepam-density functional theory combined with NMR and FT-IR spectroscopy Reorientation of the molecule of diazepam was investigated by calorimetric methods, IR absorption and NMR. The investigation of dynamics was complemented by density functional study (DFT) of vibrational frequencies and infrared intensities, calculations of steric hindrances and Monte Carlo simulations. The results indicated the occurrence of reorientation jumps of the CH3 group and conformational motion of the benzodiazepine ring. The activation parameters of the methyl group reorientation were determined and the activation barrier obtained was in good agreement with the theoretically estimated value. The FT-IR spectra were assigned using results of DFT calculations. (C) 2010 Elsevier B.V. All rights reserved.

		1H NMR study of hydrogen bonding and molecular dynamics of 5CB confined to molecular sieves It has been found that the main mechanism of H-1 protons spin-lattice relaxation of bulk 5CB at 200 MHz is its intramolecular motion, namely, the reorientation of CH2 and CH3 groups of its alkyl chain. Activation parameters of such motions have been estimated. Drastic decrease in proton spin-lattice relaxation times at the nematic-to-isotropic phase transition can be explained by the activation of molecular translational diffusion and reorientations around long and short molecular axes of bulk 5CB. Our NMR analysis revealed the slowing-down of molecular dynamics of confined 5CB molecules and their fragments. This can be explained by the interaction of some part of 5CB molecules with the surface active Si(Al)-OH centers of MCM matrix via hydrogen bonds of Si(Al)-(OHN)-N-... drop C-type.

		1H NMR spectra of 5CB liquid crystal and 5CB-MCM heterogeneous system It is shown that, in the 1H NMR spectra of 5CB, the splitting of proton bands is the result of the dipole-dipole interaction. Using the value of the splitting of the 1H bands, we determined the order parameters S for some fragments of 5CB molecules in the nematic phase. It is found that the values of S for the biphenyl core are twice greater than that for alkyl radical, which is the evidence for different dynamics of these structure fragments. From the analysis of the form of bands in the 1H spectra in the hetereogeneous system 5CB-MCM, we showed that, in the temperature range of the existence of the nematic and crystal phases of bulk 5CB, there is no ordering of these molecules in the channels of MCM. This is caused by the appearance of defects in the liquid crystal ordering due to the interaction of some part of the LC molecules with the active centers of the surface of MCM channels.

		Molecular dynamics in solid pyridoxine as studied by 1H NMR Spin-lattice relaxation times T-1 and T-1d as well as NMR second moment were employed to study molecular dynamics of pyridoxine (vitamin 136) in the temperature range 10-350 K. The T-1 minimum observed at low temperatures at 200 MHz is attributed to a motion of methyl group. The motion is interpreted in terms of Haupt's theory, which takes into account the tunneling assisted relaxation. At low temperatures, where T-1 is temperature independent, occupation of the ground state only is assumed. A motion of proton of the hydroxyl groups or CH2OH groups probably provides additional mechanism of relaxation, in the high-temperature region. (C) 2003 Elsevier Inc. All rights reserved.

The behaviour of confined TBC can be explained assuming that the guest molecules form two distinct phases; the surface-affected phase, composed of molecules located at the pore surface, and the bulk-like phase located at the centre of the pores. The bulk-like component of confined TBC, at the temperatures corresponding to the phase III, is characterized by two dynamically different subphases. (C) 2003 Elsevier Inc. All rights reserved.

		Translational diffusion in tert-butyl chloride confined to MCM-41 The translational diffusion of bulk and confined to pores of 38 Angstrom of MCM-41 tert-butyl chloride was investigated in the temperature range 293-160 K by PFGSTE experiment. The diffusivity of bulk TBC undergoes a discontinuous reduction at the melting point. The activation energy of the process was calculated to be 15.4 kJ/mol in the liquid phase and 40.6 kJ/mol in the plastic phase. Diffusivity of TBC confined to MCM-41 is described by strongly non Gaussian propagators and the echo attenuation for long diffusion times exhibit diffusion diffraction.

		Dynamics in tert-butyl chloride confined to MCM-41 The molecular dynamic of tert-butyl chloride confined to pores of 24.4 Angstrom of MCM-41 is investigated by deuterium NMR spectroscopy. The temperatures of the all phase transitions are depressed by about 10 K in porous MCM-41 relative to the bulk transitions. The rotation of the (CD3)(3) about C-CI (C) axis is less restricted than CD3 rotation about C-C bond (C-3) axis. Variable temperature lineshape analysis yield the activation energy for C3 rotation of E-a = 5.2 kcal/mol in good agreement with E-a = 4.5 kcal/mol obtained from the temperature dependence of spin-lattice relaxation times.

		Molecular motion in solid all-trans retinoic acid (vitamin A acid) by proton NMR An investigation of the molecular dynamics of all-trans retinoic acid (vitamin A) has been carried out in the solid state by proton NMR. Measurements were made of T-1 at 14 and 25 MHz and of second moment at 25 MHz in the temperature range 55 to 420 K for both monoclinic and triclinic forms. In the monoclinic state relaxation was attributed to methyl group reorientation below 250 K and to conformational motion of the cyclohexene ring above this temperature. Activation energies and time constants were derived for the motions. In the triclinic state the same motions were active, but the cyclohexene ring motion was less restricted and some of the methyl group motions were more restricted indicating that hindrances to the motions were at least partly determined by the intermolecular packing arrangements.

		Molecular dynamics in solid L-adrenaline by proton NMR Proton NMR measurements of the spectrum, second moment, spin-lattice relaxation time T-1 and dipolar relaxation time T-1D were carried out on polycrystalline L-adrenaline at 14 and 25 MHz between 55 and 400 K. Between 70 K and 250 K relaxation is dominated by C-3 reorientation of the single methyl group in each molecule, characterized by an activation energy 8.3 ± 0.3 kJ/mole. Below 70 K tunnelling assisted relaxation is significant, characterized by an excitation energy of 1.9 ± 0.2 kT/mole. Above 250 K an additional molecular motion becomes significant, with activation energy above 28 kT/mole, attributed to conformational motion of the methylene group in the ethylamine side chain.

		Proton NMR study of molecular motion in solid cortisone Polycrystalline cortisone (17,21-dihydroxy-4-pregnene-3,11,20-trione, C21H28O5) has been investigated by proton NMR methods between 56 and 400 K at 14 and 25 MHz. Reductions in second moment and two very well-resolved minima in the spin-lattice relaxation time at both frequencies are attributed to reorientation of the two methyl groups on carbons 18 and 19. The data are very well fitted over the entire temperature range to the Kubo-Tomita dipolar relaxation theory using the same parameters at both frequencies. Activation energies Ea characterizing the hindrances to the two methyl reorientations were 5.9 and 15.5 kJ/mol, an unusually large difference. The relaxation constants were 6.4 and 7.9 × 108 s-2.

		Anisotropy of rotational diffusion in liquid alpha,omega-dichloroalkanes From the analysis of 1H and 13C spin-lattice relaxation times and self-diffusion coefficients measured for α,ω-dichloropentane, -hexane and -octane, the rotational diffusion coefficients of the prolate ellipsoid type molecules treated as rigid symmetrical tops are derived. The effect of slow internal motions on the predominant dipolar relaxation is shown to be negligible as compared to the overall reorientation. The evidenced anisotropy is very pronounced — reorientation about the major symmetry axis is over ten times faster than about the perpendicular axes. Some hydrodynamic models, tested by the experimentally determined intramolecular contributions to the proton spin-lattice relaxation rates, appear to be insufficient for the adequate description of the motional behaviour.

		NMR study of solid cholesterol Anhydrous polycrystalline cholesterol C27H46O has been investigated by pulsed proton magnetic resonance methods between 77K and the melting point (421·7K). In the low-temperature phase, measurements of the spin-lattice relaxation time T 1 at 7, 14 and 28 MHz together with T 1D and second moment are ascribed to reorientation of the five methyl groups, one of which has significantly less hindrance. Values of the relaxation constants, activation energies and time factors that best characterize the motions are tabulated. Above the phase transition at 311K, reorientation of the alkyl chain about C-C bonds with activation energy 34·3 kJ mol-1 is evident from the measured values of T 1D and second moment.

On the basis of the Eyring theory the effect was confirmed and the jump length of about 7 A for all the molecules was derived. The same jump length for longer molecules was obtained from the Cohen-Turnbull free volume theory.
