Electrical conductivity and viscosity are measured in CaO–MgO–SiO 2 and CaO–BaO–SiO 2 melts to address the cationic effect on electrostatic interaction and strain field distortion based on the Anderson–Stuart theory. Electrical conductivity and viscosity at 1873 K are measured by two‐plate method and rotating cylindri…
ABSTRACT The study of the flexural behavior of the polypropylene/mica system with modified interface by the presence of an interfacial agent obtained from an industrial polymerization by‐product is one of the purposes of present work. The interfacial agent used was a p‐phenylen‐bis‐maleamic grafted atactic polypropyle…
ABSTRACT Novel fluorinated reactive surfactants were used for the organic modification of monmorillonite clays. These organoclays were used for the preparation of polystyrene−clay nanocomposites by in‐situ free radical polymerization. Reference systems based on hydrocarbon homologous surfmer and nonpolymerizable surfa…
We report a new strategy for improving the efficiency of non-specific amyloidosis therapeutic drugs by coating amyloid-responsive lipid bilayers. The approach had drawn inspiration from amyloid oligomer-mediated cell membrane disruption in the pathogenesis of amyloidosis. A graphene-mesoporous silica hybrid (GMS)-supp…
We present a detailed theoretical study of bilayer-graphene's electronic properties in the presence of electric and magnetic fields. Using group-theoretical methods, we derive an invariant expansion of the Hamiltonian for electron states near the $\mathrm{K}$ point of the Brillouin zone. In contrast to known materials…
The dynamics of multicomponent metallic alloys is spatially heterogeneous near glass transition. The diffusion coefficient of one component of the metallic alloys may also decouple from those of other components, i.e., the diffusion coefficient of each component depends differently on the viscosity of metallic alloys.…

Control of multi-martensite phase transformations and physical properties constitute greatly unresolved challenges in Fe 7 Pd 3 -based ferromagnetic shape memory alloys.Single crystalline Fe 7 Pd 3 thin films reveal an austenite to martensite phase transformation, continuously ranging from the facecentered cubic (fcc)…
Red emission intensity was optimized in three stages, by investigating the effects of: (i) host composition (Gd, Y and Gd/Y), (ii) codoping Li(+) as a sensitizer and, finally, (iii) with a SiO2 shell coating as a protecting layer. Lanthanide vanadate powder phosphors were synthesized using a modified colloidal precipi…
ABSTRACT Zirconia (ZrO2) nanoparticles were synthesized by hydrolysis and condensation of zirconium‐n‐propoxide (ZNP) in 1‐propanol at the presence of methacrylic acid (MA), serving as a chelating agent for ZNP. The formed nanoparticles were chemically modified by the UV‐curable coupling agent, 3‐(trimethoxysilyl)prop…
Low temperature transport in multiwalled carbon nanotubes (MWNTs) has been studied at different diameters and lengths, within $2\text{--}10\phantom{\rule{0.16em}{0ex}}\mathrm{nm}$, and $0.3\text{--}3.5\phantom{\rule{0.16em}{0ex}}\ensuremath{\mu}\mathrm{m}$, respectively. In a majority of the samples, semiconductivity…
The fullerene C70 may be considered as the shortest possible nanotube capped by a hemisphere of C60 at each end. Vibrational spectroscopy is a key tool in characterising fullerenes, and C70 has been studied several times and spectral assignments proposed. Unfortunately, many of the modes are either forbidden or have v…
ABSTRACT The purpose of this work was to add economic value to crambe meal, the protein‐rich byproduct from the industrial extraction of Crambe abyssinica seed oil, by using it as a potential feedstock for oilseed meal‐based plastics. The feasibility to produce continuous, flexible plastic films of glycerol‐plasticize…
ABSTRACT Potato peel powder (POPL), which is biodegradable, has been used as filler material in polypropylene (PP) matrix in varying concentration from 10 to 40% by weight to prepare biocomposites and investigated water absorption, physicomechanical and thermal properties. Scanning electron microscopy and X‐ray diffra…
The effect of asymmetric rolling with cone-shaped rolls on ultra-fine grain evolution was investigated. To do this, low-carbon steel containing 0.15 % C (mass fraction) billet (h|b|l = 10|45|100 mm3) with the initial average grain size of 60 μm was deformed up to the thickness of 5mm in cone-shaped rolls with diameter…
The authors present and discuss a method for simultaneous quantitative analysis of total loss on ignition (LOI) (CO 2 + H 2 O) and CO 2 content separate from the LOI, in an industrial environment of quicklime production. Total LOI is determined by the Compton scattered Rh Kα tube radiation which is used directly in th…
The conventional grinding wheels employment is an economically viable alternative on Austempered ductile iron (ADI) grinding. The machining of this iron is in most cases performed with superabrasive grinding wheels, requiring machine tools with higher costs. The ADI grinding with conventional grinding wheels can produ…
The effects of isothermal holding time on precipitation behaviour and resultant hardness were investigated in detail. Of particular note, with prolonged isothermal holding time at 650, 700 and 750° C, the hardness peak moves to a higher value, nearly remains unchanged, and to a lower value, respectively. It has been d…
OBJECTIVES: We investigated whether the combination coating of a novel "prohealing coating" hyaluronan-chitosan (HC) and anti-CD34 antibody applied on an SES (HCASES) can reduce neointimal formation while promoting endothelialization compared to either agent alone. BACKGROUND: Drug-eluting stents have considerably red…
Abstract Hydrogen peroxide is well known as one of environmentally benign reagents for the oxidation of starch. The aim of this work was to develop a simplified model for the describing of mass transfer and reaction kinetics phenomena of non‐catalytic and iron complex catalysed starch oxidation using hydrogen peroxide…
