We carry out Brownian dynamics simulations and study the crystallization of particles in an inverse pyramidal-shaped container induced by an external force. Owing to the side walls of the container, the face-centered cubic (fcc) structure is mainly formed. In the bulk, both disordered solidlike particles and hexagonal…
Chemically synthesized graphene contains large number of defects which act as localized spin moments at the defect sites. Cobalt nanosheets of variable thickness are grown on graphene surface to investigate spin/magnetotransport through graphene sheets containing large number of localized spins. Negative magnetoresist…
In order to understand the evolution of chemical structure in glasses, Raman features were fitted into different peakfitting functions, including Gaussian and Lorentzian types. It was found that, while single function was used for peakfitting, Gaussian function showed better fitted curves in overlapping bands than Lor…
pH‐sensitive poly[2‐(diethylamino)ethyl methacrylate]‐modified vesicular silica (VS‐PDEAEMA) is prepared in different amounts of 2‐(diethylamino)ethyl methacrylate via activators regenerated by electron transfer for atom transfer radical polymerisation. The pH‐responsive polymer is successfully grafted onto the shell…
Abstract Generally, it is very difficult to obtain multistimuli-responsive hydrogel particles. Here, we introduce a novel method for the preparation of multistimuli-responsive hydrogel particles by adding water into the poly(ethylene glycol) (PEG)-based hyperbranched polymers. The produced PEG-base polymers via revers…
Indian Sarsaparilla (Hemidesmus indicus R. Br.) is widely used in Indian traditional medicine. In the present work, we explored the effects of decoction, traditional Ayurvedic preparation, and hydroalcoholic extract, a phytocomplex more traditionally studied and commercialized as food supplement in western medicine, f…
Wire matrix inserts are used in different applications of tubular heat exchangers to improve tube side heat transfer. They have also been used to suppress fouling in crude oil refining services. In this paper it is investigated whether the changed hydrodynamic and thermal conditions when applying wire matrix inserts h…
Highly photoluminescent gel was prepared by embedding water soluble quantum dots (QDs) in an inorganic–organic hybrid gel matrix using a conventional sol–gel process. Aminopropyltrimethoxysilane and citric acid (CA) were found to be the best combination for the gel preparation. 13 C-NMR and FT-IR studies indicated hyd…
Water-soluble cadmium sulfide (CdS) nanoparticles were synthesized through aqueous thermochemical method using thioglycolic acid as a capping agent. The resulting CdS nanoparticles were characterized using x-ray diffraction, field-emission scanning electron microscopy, ultraviolet–visible, and photoluminescence spectro…
We report on the visible light induced photocatalytic responses of zinc oxide (ZnO) nanostructures in the form of nanowires and nanowalls grown on aluminum substrates. Morphological and microstructural characteristics of these nanostructures have been analyzed using scanning electron microscopy (SEM) and high resoluti…
ABSTRACT The use of natural additives, with low toxicity and good compatibility, for PVC is becoming increasingly attractive. In this study, soybean oil additives were prepared by air oxidation reactions and blending with PVC. The oxidation reaction produced a significant increase in the number of hydroxyl groups in s…
In this work we study the terahertz light propagation through deeply-scaled graphene-based reconfigurable metasurfaces, i.e. metasurfaces with unit-cell dimensions much smaller than the terahertz wavelength. These metasurfaces are analyzed as phase modulators for constructing reconfigurable phase gradients along an op…
Designs of cloaking devices and more general invisible objects have primarily applied the techniques of transformation optics and scattering cancellation to derive material structures that achieve the desired effects. In this Letter, we note that it is also possible to construct a broader class of invisible objects di…
An equivalent circuit model of ‘U’-shaped split-ring resonators (SRR), the basic structure of SRR has been proposed and studied. The proposed model, other than traditional equivalent circuit model, has taken both the influence of geometrical parameters and dielectric substrate into account and investigated them in det…
A [Ru(phen)3](2+) complex (phen = 1,10-phenanthroline) having an arylethynyl group at the 4-position of one of the three phen ligands (aryl: (dimesityl)borylduryl group = [RuBE](2+) or duryl group = [RuDE](2+)) showed dual emissions at low temperature in propylene carbonate (PC). The shorter emission lifetime componen…

The aim of this study was to measure the thermal properties of foamed nano/macro filler–reinforced styrene maleic anhydride (SMA) composites. SMA (66%) as a polymer matrix (10% maleic anhydride content) and various fillers including wood flour, starch, α-cellulose, microcrystalline cellulose and cellulose nanofibrils…
Composites of ferromagnetic and ferroelectric are of interest for studies on mechanical strain mediated magneto-electric (ME) interactions and for useful technologies. Here, we report on magnetic-field-assisted-assembly of barium titanate (BTO)-nickel ferrite (NFO) core-shell particles into linear chains and 2D/3D arr…
In this work, an experimental study was conducted on two different types of gelatin from mammalian sources; type A, derived from acid-cured tissue of porcine skin and type B, from lime-cured tissue of bovine skin. The effect of temperature, pH, and ionic strength on viscoelastic properties of gelatin hydrogels was car…
Thin foil dog bone samples prepared from a hot rolled Zr-2.5Nb alloy have been deformed by tensile deformation to different plastic strains. The development of slip traces during loading was observed in situ through SEM, revealing that deformation starts preferentially in certain sets of grains during the elastic-plas…
