Diamond film growth without seeding treatment has been the subject of numerous studies. In this study, diamond films with/without seeding treatment were grown on silicon using hot-filament chemical vapour deposition. An inexpensive and simple approach, namely ‘dry ultrasonic treatment’, was introduced in which full co…
Abstract In this study, the alicyclic dianhydrides 1,2,3,4‐cyclobutanetetracarboxylic dianhydride (CBDA) was polymerized with seven kinds of fluorinated aromatic diamines, 2,2′‐bis(trifluoromethyl)‐4,4′‐diaminobiphenyl (1), 1,4‐bis(4‐amino‐2‐trifluoromethylphenoxy)benzene (2), 1,4‐bis(4‐amino‐2‐trifluoromethylphenoxy)…
Composites are produced based on diamond particles having monomodal or mixtures with bimodal size distribution contained in silver-based alloys. The composites were produced by gas pressure-assisted liquid metal infiltration with the aim to maximize thermal conductivity. The diamond content ranged between 60 and 79 vo…
Background: The growing problem of environmental pollution caused by synthetic plastics has led to the search for alternative materials such as biodegradable plastics. Of the biopolymers presently under development, starch/natural rubber is one promising alternative. Several species of bacteria and fungi are capable o…
Crystalline silk fibroin nanoparticles (CSFs), a kind of natural protein nanocrystal, were prepared by treatment of silk fibroin (SF) powders with 64 wt% aqueous sulfuric acid. Various treatment periods were tested, and optimal conditions corresponded to 2 h at 45 °C. Transmission electron microscopy observation showe…
Cadmium (Cd) is a metal used in various industrial applications, thereby causing exposure to Cd-containing fumes. The submicron-sized particles in the fumes represent an extra risk due to their high mobility within the organism and high surface area. Toxicity of Cd on the liver, kidney and bones is well known, but the…
The conformational changes, crystal structure and melting behavior of poly(ethylene/trimethylene terephthalate) (ET) copolyesters were investigated using in situ Fourier transform infrared (FTIR) spectroscopy, wide-angle X-ray diffraction (WAXD), transmission electron microscopy (TEM) and differential scanning calorim…
Abstract Effect of the orientation of cylindrical pores within an anode has been studied on the performance of anode‐supported solid oxide fuel cell (SOFC). Paper‐fibers are used as pore‐former and highly oriented cylindrical pores are formed within the anode prepared by uniaxial compaction. A thick anode brick is fab…
Temperature-programmed desorption (TPD), high-resolution electron energy loss spectroscopy (HREELS), and density functional theory (DFT) were used to investigate the thermal surface chemistry of 2-iodoethanol (ICH 2 CH 2 OH) on Pd(111). 2-Iodoethanol undergoes C–I scission upon adsorption at low temperatures, resultin…
Abstract The performance of solid oxide cells (SOCs) heavily relies on the population of three‐phase boundaries (TPBs) in the composite electrodes. In this study, SOC composite electrodes are described by percolating binary particle aggregates that are constructed from random loose packing models and classical sinteri…
In this paper, catalytic samples of 10, 20, 30, 40 and 50% (w/w) urea/activated carbon fibre (AFC), 10% urea--5% La2O3/ACF, 10% urea--10% La2O3/ACF, 10% urea--15% La2O3/ACF, 20% urea--5% La2O3/ACF, 20% urea--10% La2O3/ACF, and 20% urea-15% La2O3/ACF were prepared and used for removal of NO under the condition of: NO,…
CONTEXT: In India, Dregea volubilis (L.f.) Benth. ex Hook.f. (Asclepediaceae), a large twining shrub with a woody vine, is used to treat tumors traditionally. OBJECTIVE: This study evaluated the in vitro and in vivo antitumor activity of the methanol extract of Dregea volubilis leaves (MEDV) and elucidated its possibl…
Combined refinements of local atomic structure that involve simultaneous fitting of powder-averaged and single-crystal data were implemented as an extension to the publicly available RMCProfile software. The refinements employ the reverse Monte Carlo method to fit neutron total scattering data, the neutron Bragg profi…

Industrial wood particles used for manufacturing three-layer particleboards were used to prepare wood-polypropylene composites by an injection molding process. The effect of particle size (0.25-0.5, 0.5-1, 1-2, and 2-4 mm) on mechanical properties of composites was investigated. Additionally, the effect of cross-secti…
Anisotropic broadening correction in X-ray powder diffraction by an ellipsoidal formula is applied on samples with nanosized crystals. Two cases of minerals with largely anisotropic crystallite shapes are presented. The properly applied formalism not only improves the fitting of the theoretical and observed diffractio…
We present a method for grafting silanes onto low-temperature-plasma synthesized silicon quantum dots. The resulting solution of dots is characterized with Fourier transform infrared spectroscopy and transmission electron microscopy, and determined to be a colloidal suspension. The silane is attached at a single point…
Nanocrystalline Ni thin films have been produced by direct current electrodeposition with different additives and current density in order to obtain 〈100〉, 〈111〉 and 〈211〉 major fiber textures. The dislocation density, the Burgers vector population and the coherently scattering domain size distribution are determined…
Ligand influence on the excited state structure of small neutral gold clusters (Au 2 and Au 4 ) has been investigated using Time Dependent Density Functional Theory. We study in detail the absorption profile of bare and ligated small gold clusters in solution modeled with Polarizable Continuum Model. Performance of CA…
Abstract The structural integrity of the sealing material is critical for the reliability of solid oxide fuel cell stacks. In this respect failure and deformation are aspects which need to be assessed in particular for glass ceramic sealant materials. Bending tests were carried at room temperature and typical stack op…
