In this work the optimum resination rate of white mustard straw particles with UF resin in the production of straw particleboards was investigated. The resination rates used in this study were 10, 12 and 14%. For the selected resination rate, the possibility of reducing the density of the straw particleboards was also…
Inerting is an important measure to prevent fire and explosion, and enhance the survivability of an aircraft. In the battle environment, the hits from the projectiles or fragments on the fuel tank may affect the inerting effectiveness. By modifying the traditional scrubbing inerting model, this paper proposes a new in…
We investigate swelling induced pattern transformation of pH-sensitive hydrogel membranes made of poly(2-hydroxyethyl methacrylate)- co -poly(acrylic acid) (PHEMA- co -PAA) with periodic pores in both square and oblique arrays. The hydrogel membranes are fabricated by replica molding from a poly(dimethylsiloxane) (PDM…
Warp-knitted brushed fabrics are special pile fabrics with uneven and declining piles that consist of broken filament ends. It is difficult to predict the finial pattern of the pile surface in the process of the design of patterned fabric. There are few researches on computer simulation of the fabric because of their…
A new vinyltrimethoxysilane-based hybrid silica monolith was developed and used as a reversed-phase capillary column. The synthesis of this rich vinyl hybrid macroporous monolith, by cocondensation of vinyltrimethoxysilane with tetramethoxysilane, was investigated using an unconventional (formamide, nitric acid) porog…
The paper presents methodologies and results concerning one-and two-dimensional numerical modeling of radio frequency oscillations in a coaxial transmission line fed with a short pulse of electric current. The line is partially filled with a ferrite material, magnetized longitudinally close to saturation. The 2D model…
An anionic heptacopper(II) oxo-cluster {Cu7} was obtained from a simple reaction in aqueous solution without heating. In a similar reaction, another cage compound {Sb12} with an encapsulated {Cu2} core was produced, implying the structural versatility of copper(II)-oxide assemblies constructed from potassium antimonyl…
We here explore a kinetically controlled synthetic protocol for preparing solvent-solvable Au102(SPh)44 nanoclusters which are isolated from polydispersed gold nanoclusters by solvent extraction and size exclusion chromatography (SEC). The as-obtained Au102(SPh)44 nanoclusters are determined by matrix-assisted laser d…
Influence of intercalation on the electronic band structure of the layered nanohybrid compound of the GaSe-type with a stage ordering (three layers in the packet in the considered case) is studied in the modified version of the periodic Anderson model. Density of electron states for the intercalated system is calculat…
ETHYLENE-PROPYLENE-DIENE rubber (EPDM/ nano-filler) composites were prepared and crosslinked by gamma rays. The composites either contain 40phr of fumed silica, 40phr of zirconium silicate, separately, or different ratios from both ranging from 30:10-10:30, respectively. The effect of the presence of these fillers in…
The electronic structures of Ag6M2O7 (M = Si, Ge) are investigated by the scalar-relativistic full potential linearized augmented plane wave plus local orbital (FLAPW+lo) method using the modified Becke-Johnson (MBJ) potential combined with the local density approximation (LDA) correlation. For Ag6M2O7 (M = Si, Ge), t…
Vibration suppression of a strain gradient Euler–Bernoulli beam in presence of disturbance and uncertainties is considered in this investigation. Vibration of the system is suppressed by an adaptive boundary controller which has robustness to the environmental and control effort disturbances. The direct Lyapunov stabi…
Perylene bisimides dye-based water-soluble fluorescent polymer P3, N,N'-bis(3-amyl)-1-bromo-7-{4'-[3''-(S-poly(N-acryloyl ethylene diamine hydrochloride)-2'''-methyl propionic acid)propionyloxy hexyloxy]phenyl} perylene-3,4:9,10-tetracarboxylic bisimides, was synthesized with polyelectrolyte modification via one-pot r…

Nb5+ or W6+ donor-doped powders were synthesized by applying a mechanochemical synthesis route, in an attempt to improve the multiferroic properties of BiFeO3 based materials. The as-synthesized samples evidence a highly efficient incorporation of Nb5+ or W6+ into the BiFeO3 perovskite lattice, together with a low pre…

Each uric acid molecu…
Nanocrystalline gadolinium niobate, GdNbO4 with fergusonite structure was directly formed from the precursor solution mixtures of GdCl3 and NbCl5 under weakly basic conditions at temperatures higher than 210°C for 5 h in the presence of aqueous ammonia via hydrothermal route. The as-prepared GdNbO4 nanocrystals and th…
In this study, we investigated the Polyurethane paint based on palm oil with the addition of nanoparticles montmorillonite as a heat-resistant.The composites with 1 wt%, 3 wt% and 5 wt% of bentonite filler content obtained by synthesizing in situ were investigated and compared to the neat polyurethane matrix material.…
Electropolishing behavior of steel was studied in orthophosphoric acid in the presence of gelatin for improving the finish obtained. This was inspected by surface tension measurement and potentiodynamic polarization by measuring the limiting current in solutions containing different concentrations of gelatin. Gelatin…
Background: Research in to transparent super-hydrophobic surfaces is of considerable interest in the present scenario, as it finds plenty of applications in both fundamental research and industry. An extensive scattering of propagated light may take place through super hydrophobic surfaces because of very high surface…
