Abstract Two rubber compounds with different amounts of chemical curatives were prepared by mixing natural rubber with a high loading of a sulfur‐bearing silanized precipitated amorphous white silica nanofiller. The chemical bonding between the filler and rubber was optimized via the tetrasulfane groups of the silane…
Inter-Landau-level transitions in the bilayer graphene in high perpendicular magnetic field at the filling factor $\ensuremath{\nu}=0$ have been studied. The next-nearest-neighbor transitions, energy difference between dimer and nondimer sites, and layer asymmetry are included. The influence of Coulomb interaction is…
Abstract In this study, transparent poly(methylmethacrylate) (PMMA)‐silicone hybrid materials, P(MMA‐ co ‐SigUMAx), were prepared with methylmethacrylate (MMA) and multifunctional silicone macromonomer introduced methacryl groups. The transmittance of hybrid materials improved with increase of methacryl groups of sili…
Based on three quantum chemical descriptors (the average polarizability of a molecule (α), the most positive net atomic charge on hydrogen atoms in a molecule (q+ ) and the heat capacity at constant volume (Cv ) derived from the monomers using the density functional theory (DFT), the support vector regression (SVR) ap…
Pulsed neutron diffraction and inelastic neutron scattering were performed on the orthorhombic perovskite PrCoO${}_{3}$ to investigate possible spin-state transitions arising from Co${}^{3+}$ ions. Although the crystal symmetry is orthorhombic, no evidence for a Jahn-Teller distortion is observed in either the average…
The morphological and microstructural changes during ball milling of PE powder mixed with different weight percent (5–15 wt%) of Alumina particles (50–100 nm) were studied. The milling was performed in a planetary ball mill for various times up to 40 h. The results showed that the addition of hard particles accelerate…
Abstract Polystyrene copolymer beads supported dendrimer was synthesized and investigated for its biological applications. Macroporous cross‐linked polystyrene copolymer beads were synthesized using suspension polymerization. Two successive generations of di(chloroethyl) amine‐type end group functionality was formed o…
Abstract A trifunctional organo alkoxysilane (3‐aminopropyl)triethoxysilane (γ‐APS) has been used as reagent for the chemical modification of montmorillonite clay. Silane grafting was taken place in dry and hydrolyzing conditions. Silane grafted and pristine clay took part in interfacial polycondensation process to de…
When increasing the wood fiber (WF) content in extruded wood fiber/plastic composites (WPC) foams, a good balance between reducing the cost and obtaining good cell morphology should be maintained. This study examines the relationship between WF content and the foam morphology in WPC foams. The role of WF as cell nucle…
Dielectric material CaCu3Ti4O12 (CCTO) was prepared by solid state technique. CaCO3, TiO2, and CuO powders were mixed thoroughly in a ball mill for an hour and were calcined at 900 °C for 12 h. This is followed by sintering at a defined standard temperature for this work (1050 °C for 24 h). Other samples were prepared…
We present quantum chemistry simulations of aluminum clusters surrounded by a surface layer of cyclopentadiene-type ligands to evaluate the potential of such complexes as novel fuels or energetic materials. Density functional theory simulations are used to examine the aluminum-ligand bonding and its variation as the s…
Abstract Carbon nanomaterials are the promising candidates for potential broadband limiting applications and extremely low reflectance coatings, particularly in the infrared, visible and UV spectral regions. In this paper we have performed the comparative study of diffuse reflectance of nanodiamond (ND), sp 2 /sp 3 co…
In this letter we have studied broadband conductivity spectra (10 Hz–3 GHz) of fast-ion-conducting silver selenite glasses of compositions x AgI-(1− x )( y Ag 2 O-(1− y )SeO 2 ). We have observed that the conductivity spectra below 10 MHz are characterized by a power law with exponent less than unity, while the conduc…
Abstract With increasing environmental awareness, evaluating the potential of biopolymers as a substitute for traditional materials has been of great interest. Crystallization kinetics provides fundamental knowledge required for evaluation, playing vital role in determining the final properties of the product. In this…
The methodology of protein crystallography provides a number of potential bottlenecks. Here, an approach to successful structure solution of a difficult heterodimeric complex of two human proteins, paraspeckle component 1 (PSPC1) and non-POU domain-containing octamer-binding protein (NONO), that are involved in gene r…
Most physical properties of a wood plastic composite (WPC) with poly(vinyl chloride) (PVC) matrix are lower than those of corresponding neat PVC because of poor interfacial adhesion between hydrophobic PVC and hydrophilic wood. In this study, to improve the interfacial adhesion, wood flour was pre‐treated with N‐2(ami…
Current studies, dedicated to metallic (gold, silver, iron, and copper) nanomaterials are reviewed in this paper. This metals own unique physical and chemical properties which determine their application. The medical application of metallic nanomaterials includes therapy and prophylaxis of diseases, development of new…
Layer-by-Layer (LbL) coatings are promising tools for the biofunctionalization of biomaterials, as they allow stress-free immobilization of proteins. Here, we explore the possibility to immobilize phosvitin, a highly phosphorylated protein viewed as a model of bone phosphoproteins and, as such, a potential promotive a…
A monolithic vanadia-titania based catalyst has been subjected to studies with in situ FTIR spectroscopy coupled with mass spectrometry, during the SCR (Selective Catalytic Reduction) reaction. A device based on a transmission reactor cell for monolithic samples was constructed, dedicated to the study of surface speci…
Application of high electric field is effective for the alignment of carbon nanotube (CNT) in a nanocomposite film. The conventionally used single pair of parallel plate electrodes is not applicable to large-sized nanocomposite fabrication due to limited output voltage of the high-voltage source. We have proposed an a…
