It is shown that heating of an internal layer of microarc coating up to temperatures at which insignificant rates of heat removal from microdischarges that possess a temperature of no less than 1200°C are ensured leads to realization of a sufficient time interval for the occurrence of almost 100% transformation of low…
The effects of temperature, exposure, and agitation of the solution on the passivating properties of sodium dioctyl phosphate are studied. It is found that passivation of steel in the presence of the salt can proceed without the formation of surface oxide.
Various amounts of antimony doped tin oxide (ATO) nanoparticles were incorporated into waterborne polyurethane (WPU) dispersions by sol–gel reactions. The dispersion state and morphology investigated by transmission electron microscopy (TEM) and scanning electron microscopy (SEM) showed that the nanoparticles can disp…
Size parameters of SiO 2 /TiO 2 hollow nanoparticles (HNPs) of 25–100 nm in diameter were characterized by small-angle X-ray scattering (SAXS). On the basis of the decoupling and the Percus–Yevick approximations, and using a hollow sphere model, size information on HNPs was extracted, including average outer diameter,…
Abstract Soft metalorganic grafting of periodic mesoporous silica (PMS) materials is introduced as a method for obtaining nanostructured Gd III ‐loaded silica particles with relatively high 1 H relaxivity. The silylamide complex Gd[N(SiHMe 2 ) 2 ] 3 (THF) 2 was grafted onto MCM‐41, SBA‐15, and SBA‐1, thereby providing…
In present work, silica pillared montmorillonite material (C-SiO2-OMT) was prepared via the sol–gel method, and the influence of the powder on thermal stability and flammability performance of polypropylene (PP) composites was investigated. Characterization of C-SiO2-OMT, elucidated with X-ray diffraction, transmissio…
We rationally designed a bioadhesive supramolecular hydrogel by introducing L-3,4-dihydroxylphenylalanine (DOPA) groups while properly integrating the enzymatic reactions and self-assembly processes. The effective presence of the catechol groups successfully promoted the adhesion and proliferation of human fibroblast…
A silicon-germanium (SiGe) alloy is a promising candidate for thermoelectric materials; while it shows a significantly reduced thermal conductivity (κ) as compared to pure Si and Ge, the κ values obtained from previous experiments and computations tend to be widely scattered. We present here a computational analysis o…
Interrelations between the degree of uniaxial preferred orientation and the intensities and widths of selected X-ray diffraction peaks are analyzed within the March–Dollase approach. Simple analytical expressions are developed which relate the degree of preferred orientation to the rocking curve width of the strongest…
Two new approaches to quantitatively analyze diffuse diffraction intensities from faulted layer stacking are reported. The parameters of a probability-based growth model are determined with two iterative global optimization methods: a genetic algorithm (GA) and particle swarm optimization (PSO). The results are compar…
Resonant excited state absorption (ESA) and relaxation processes in Tb(3+)-doped aluminosilicate glasses are quantitatively evaluated. A model describing the excitation steps and upconversion emission is developed and applied to interpret the results from laser-induced surface deformation using thermal mirror spectros…
In this study, a green composite was produced from Oil Palm Trunk Lumber (OPTL) by impregnating oil palm shell (OPS) nanoparticles with formaldehyde resin. The changes of physical, mechanical and morphological properties of the OPS nanoparticles impregnated OPTL as a result of natural weathering was investigated. The…
Dielectric and electro-optical properties of liquid crystal (LC) dispersions exhibiting two different surface anchoring conditions at the polymer-LC interface are investigated. The confining surface was tuned by changing the side chains of the polymeric matrix in order to get either planar or homeotropic anchoring con…
Colloidal gold nanoparticles intensify the anticancer response of the drug bortezomib, a proteasome inhibitor. Polyethylene glycol-coated gold nanoparticles and the drug show a synergistic effect in reducing the cell viability of prostate cancer cell line Du145. It was observed a significant cell viability reduction w…
TNFα-related apoptosis-inducing ligand (TRAIL) induces death selectively in cancer cells. However, subpopulations of cancer cells are either resistant to or can develop resistance to TRAIL-induced death. As a result, strategies that overcome this resistance are currently under investigation. We have recently identifie…
The effects of type of processing of polypropylene (PP)/wollastonite composites on mechanical properties and dispersion state were investigated. The concentration in weight of the filler in the compounds was of 2.5%, 5%, and 10%, respectively. Stearic acid was used as an interface modifier for the PP–wollastonite syst…
We have investigated the macroscopic and microscopic properties of large sets of Ba0.7Sr0.3TiO3 thin films including several substitution rates of manganese. Thanks to a high degree of control of the processing parameters at each stage we have been able to find a link between the dc leakage current and the low and hig…
Polylactic acid (PLA)‐based composites containing 1, 3, and 5% by weight of talc microparticles were prepared by extrusion and characterized in terms of thermal, structural, and morphological issues. The binary materials were then compared with ternary systems including 5% by weight of a secondary poly(ε‐caprolactone)…
The focus of this study was to evaluate the growth of the cells on a scaffold based on novel polyhydroxyalkanoate (PHA) (Polyhydroxy propionate copoly hydroxy ocatadecanoate copolymer), derived from a mutant strain of Pseudomonas sp. Naive PHA was also blended with several biodegradable polymeric materials (PEG, PLA,…
This report describes efficient plasmid uptake by the thermophile Geobacillus kaustophilus HTA426 by means of a ternary conjugation system, which was used to construct thermophile DNA libraries for G. kaustophilus and to identify the genes for orotidine-5'-phosphate decarboxylase by in vivo functional screening. The r…
