It is commonly accepted that titanium and the titanium alloying elements of tantalum, niobium, zirconium, molybdenum, tin, and silicon are biocompatible. However, our research in the development of new titanium alloys for biomedical applications indicated that some titanium alloys containing molybdenum, niobium, and s…
IMPORTANCE OF THE FIELD: Although significant progress has been made in delivering therapeutic agents through micro and nanocarriers, precise control over in vivo biodistribution and disease-responsive drug release has been difficult to achieve. This is critical for the success of next generation drug delivery devices…
Radiation damage inflicted during diffraction data collection in macromolecular crystallography has re-emerged in the last decade as a major experimental and computational challenge, as even for crystals held at 100 K it can result in severe data-quality degradation and the appearance in solved structures of artefacts…
Classical density-modification techniques (as opposed to statistical approaches) offer a computationally cheap method for improving phase estimates in order to provide a good electron-density map for model building. The rise of statistical methods has lead to a shift in focus away from the classical approaches; as a r…
The programs SHELXC, SHELXD and SHELXE are designed to provide simple, robust and efficient experimental phasing of macromolecules by the SAD, MAD, SIR, SIRAS and RIP methods and are particularly suitable for use in automated structure-solution pipelines. This paper gives a general account of experimental phasing usin…
Coot is a molecular-graphics application for model building and validation of biological macromolecules. The program displays electron-density maps and atomic models and allows model manipulations such as idealization, real-space refinement, manual rotation/translation, rigid-body fitting, ligand search, solvation, mu…
Processability remains a fundamental issue for the implementation of conducting polymer technology. A simple synthetic route towards processable precursors to conducting polymers (main chain and side chain) was developed using commercially available materials. These soluble precursor systems were converted to conjugat…
Abstract Ag4[Fe(CN)6]→Ag reduction process occurring in Ag4[Fe(CN)6]- gelatin-immobilized matrices, has been studied. In the course of reduction, these matrices are in a contact with water-alkaline solu-tion containing tin(II) dichloride along with an organic or inorganic compound capable of forming a stable soluble c…
We have performed angle-resolved photoemission spectroscopy of ${\text{Na}}_{x}{\text{CoO}}_{2}$ ($x=0.65$ and 0.77) to clarify the origin of antiferromagnetic (AF) transition. We determined the electronic band structure along the out-of-plane direction by varying photon energy, and revealed that a three-dimensional e…
Two novel cyano-containing oligo(phenylenevinylene) (OPV) derivatives have been designed and synthesized. Photophysical and sensing properties of the two compounds were studied. Such studies reveal the intramolecular charge transfer process between cyano groups and OPV core. The results showed that the alkyl differenc…
Abstract This work deals with the application of the static light scattering (SLS) model of Vrij (VM) for the characterization of a spherical polydisperse concentrated polymer particle system. This model is the exact solution for the SLS of such mixture of particles in the Percus–Yevick approximation. The analyzed pol…
This study aims to assess the feasibility of fuel-reforming-assisted hydrocarbon selective catalytic reduction (HC-SCR) over 2 wt % Ag/Al 2 O 3 catalyst. For this purpose, the effects of reduction agents and the presence of hydrogen on NO x reduction over silver catalyst were tested, and, after catalytic partial oxida…
Polyethylene terephthalate (PET) granules were grafted with methyl acrylate (MA) from the solution containing 10% MA in methanol (86%) solvent and photo initiator (4%) for 10 min and then cured under UV radiation. MA-grafted PET films were prepared at 260°C and 5 ton pressure using heat press. Jute fabric-reinforced,…
The influence of nanoparticulate SiO 2 on the crystallization behavior of CsHSO 4 from aqueous solution has been quantitatively evaluated using powder X-ray diffraction (XRD) and 1 H magic angle spinning nuclear magnetic resonance (NMR) spectroscopy. It is shown that SiO 2 induces amorphization of a portion of CsHSO 4…
Abstract In this study, silk fibroin powder was treated by dielectric barrier discharge (DBD) plasma. The objective is to improve the performance of the silk fibroin powder/polyurethane (PU) blend film used in biomechanical field. The scanning electron microscope (SEM) showed that the plasma‐treated powder was broken…
We report the synthesis and characterization of a kind of silane-terminated poly(ether–urethane) (PEU)-titania elastomeric hybrid for UV and X-ray shielding application. The hybrids can be easily synthesized by a moisture-cured sol–gel process at room temperature. Strong interactions between the organic and inorganic…
Computer modeling and simulation is performed to study the domain stabilization effect due to short-range ordering of charged point defects in aged ferroelectrics. Phase field model takes into account various energetic contributions involved in domain aging phenomenon, including chemical, domain wall, electrostatic an…
Highly bulk-sensitive hard x-ray photoemission has been performed for the Magn\'eli phase ${\text{V}}_{5}{\text{O}}_{9}$ and ${\text{V}}_{6}{\text{O}}_{11}$, which are composed of ${\text{V}}_{2}{\text{O}}_{3}$ and ${\text{VO}}_{2}$ from chemical point of view. The valence-band spectra near the Fermi level are rather…
Two-component amphiphiles based on hydrogen-bonded complexes between terephthaloylbisalanine (H(2)TBA) and dodecylamine (DA) are able to self-assemble into nano- and microsized superstructures in an aqueous solvent. It is possible to modulate the morphology of these self-assembled superstructures by modifying the comp…
We report efficient and long-lived exciton photoluminescence (PL) from inverted core/shell ZnSe:Mn/CdSe nanocrystals (NCs) at room temperature. Contrary to low temperature-sensitivity of Mn2+ PL from ZnSe:Mn/ZnSe NCs, the Mn2+-assisted excitonic PL from the ZnSe:4%Mn/CdSe NCs exhibits unusually high temperature-sensit…
