A multi-speckle set-up for dynamic light scattering experiments has been implemented to investigate the relaxation dynamics in the glass-former at temperatures across the glass transition. When compared to literature data obtained with traditional single-speckle set-ups, the present results clearly show the advantages…
It is possible to associate with every atom or molecule in a liquid its own atomic stress tensor. These atomic stress tensors can be used to describe liquids' structures and to investigate the connection between structural and dynamic properties. In particular, atomic stresses allow to address atomic scale correlation…
In this study, aluminum doped zinc oxide thin films were deposited on ordinary glass substrates at the temperature of 425°C by spray pyrolysis technique for various doping concentrations of aluminum ranging from 1 to 5 at.%. The effect of dopant concentration on structural, morphological and optical properties of ZnO:…
The structure and property of Abelmoschus manihot Manihot fibers were investigated in the present work. Its transverse section was irregular polygon and the single fiber was cylindrical shape. It belonged to cellulose I crystalline structure and its crystallinity was near to cotton and ramie. The breaking strength was…
Biomaterials play a vital role in the field of regenerative medicine and tissue engineering. To date, a large number of biomaterials have been used in cardiovascular research and application. Recently, biomaterials have held a lot of promise in cardiac stem cell therapy. They are used in cardiac tissue engineering to…
Gold and silver nanoparticles green synthesized using an aqueous extract of geranium (Pelargonium graveolens) leaves were embedded in cholesterol-containing dipalmitoyl phosphatidylcholine lipid vesicles by a simple eco-friendly method, resulting in bio-based composites with antioxidant and antibacterial properties. T…
Rigid thiourethane foams were prepared from vegetable oil-based polythiols (polymercaptans) and compared with soy- and castor oil-based polyurethane reference foams. Three types of polymercaptans were tested, soybean oil-based one with thiol groups only, epoxidized soybean oil-based with vicinal thiol and hydroxyl gro…
Blend films of different ratios of carboxymethyl cellulose (CMC)/polyethylene oxide (PEO) were prepared by the solution casting method. To investigate the effect of irradiation on all properties of prepared blend, it was exposed to different gamma irradiation doses (10, 20, and 30 kGy). Physical properties such as gel…
The integrated processes of Shenmu subbituminous coal pyrolysis and CO2 reforming of methane over catalyst (Ni/SiO2) with and without using dielectric barrier discharge plasma (ICCP and ICCC) were carried out to check the effectiveness of the integrated process on improving the tar yield of coal pyrolysis. The effects…
This paper investigates the susceptibility of multilayer ceramic (MLC) capacitors to high-voltage electrical fast transients (EFTs). X7R and NP0 MLC capacitors with a 50 V voltage rating and 0603 package size were tested. X7R capacitors often failed during a spike in the voltage, but exhibited no obvious degradation i…
Diatoms were collected from the Kotulpur area of West Bengal. Four diatom taxa, namely,Eunotia minor(Kützing) Grunow,Achnanthidium minutissimum(Kützing) Czarnecki,Lemnicola hungarica(Grunow) Round and Basson, andNavicula radiosaKützing were observed using scanning electron microscopy (SEM) and identified in light of m…
Melting characteristics of high-density polyethylene (HDPE) mixed with nano-size ceramic fillers (hydroxyl apatite and yttria stabilised zirconia) was analysed using the isochronal heating rate between 10 °C min−1 and 80 °C min−1. In this investigation, the kinetics of melting of HDPE-ceramic composites was analysed u…
The effect of substrates on the magnetic and transport properties of Ni2Mn1.5In0.5 ultra-thin films were studied theoretically and experimentally. High quality 8-nm films were grown by laser-assisted molecular beam epitaxy deposition. Magneto-transport measurements revealed that the films undergo electronic structure…
Silica films containing gold nanoparticles were grown by magnetron radio frequency (rf) sputtering technique under various deposition conditions. XRD measurements revealed the formation of gold nanoparticles embedded in amorphous silica films. The structural and optical properties of the films were tailored by varying…
The global production of natural fibres is evaluated at the level 35–40 million tons/year. It is expected that the global megatrends in population growth, prosperity growth, climate change and limited cotton supply, increase in fiber consumption will lead to a demand overhang for other cellulosic fibers, including new…
Abstract We report on comparative studies of the emission properties of CdSe/ZnSe quantum dots (QDs) grown by molecular beam epitaxy either with or without predeposition of a sub‐monolayer CdTe stressor, and in the latter case, either with or without in‐situ thermal annealing. The emission of a limited number of QDs w…
This paper reports the synthesis of a hyperbranched polymer by a cost-effective one-step copolymerization of A3 and B2 monomers, namely, triethanolamine and sebacoyl chloride, respectively, followed by methylation of tertiary amine groups. The structure of the hyperbranched polymer QTEAS as an efficient material for t…
A holographic liquid crystal polarization grating with a Fabry-Perot structure was developed. Because of its resonant structure, the device offers high levels of control of the diffraction properties of incident-polarized light beams, depending on the resonance conditions. The diffracted light beams are emitted in bot…
Different xPbO–(1–x)B2O3 glasses were prepared by conventional melting method. They were investigated by differential scanning calorimetry (DSC), Raman and IR spectroscopy. The glasse's structure and the PbO role to the formation of the borate units in the framework is investigated. The dielectric constant and dielect…
The properties of epitaxial silicene monolayers on Ag(111) at various levels of oxidation are determined through complementary density functional theory calculations and soft X-ray spectroscopy experiments. Our calculations indicate that moderate levels of oxidation do not cause a significant bandgap opening in the ep…
