The Present work includes, degradation of polyethylene under different environmental conditions to know the effect of physical, chemical and biological factors prevailing in those conditions on degradation of polyethylene. Plastic films viz., Low density polyethylene (LDPE), High density polyethylene (HDPE) and High m…
The purpose of this article is to report a case for the use of industrial solid waste in substitution of fossil fuel in clinker kilns in the cement industry. The partially replaced fossil fuels originated in the oil industry. The industry calls this practice co-processing. The research took place in a cement industria…
The most probable cause of quenches of a coil wound of Bi/Ag-sheathed wires is the appearance of a long resistive zone caused by the temperature rise of the long part of the conductor due to, for example, ac losses and the malfunction of the cryogenic system. Protection characteristics of quenches by this cause are ex…
Fluorescence quantum yield of two novel compounds—dibenzo[c,k]-1,2-dithia-6,9-diazacyclododecane-5,10-dione ( 1 ) and dibenzo[c,k]-1,2-dithia-6,9-diaza-7-methylcyclododecane-5,10-dione ( 2 ) was studied by Williams method using anthracene as a reference.
We use polarization-resolved Raman spectroscopy to assess the crystal quality of epitaxial kesterite layers. It is demonstrated for the example of epitaxial Cu₂ZnSnSe₄ layers on GaAs(001) that "standing" and "lying" kesterite unit cell orientations (c'-axis parallel / perpendicular to the growth direction) can be dist…
In this work, the random phase approximation theory is applied to generate an expression for the direct correlation function based on the linear isotherm regularity equation of state. We use the hard-core Yukawa potential in the modelling of real fluids, in which the molecular parameters are state-dependent. We use th…
We present our recent development concerning the evaluation of a low energy dose application to electron beam responding materials with a simple portable optical device. Electron beam irradiation is a promising option to sterilize sensitive and high performance products or surfaces at a low temperature and without moi…
Abstract Oxidative copolymerizations of styrene (St) with α‐methylstyrene (AMS) have been studied under 100 psi (690 kPa) oxygen pressure at 50 °C in the presence of various catalysts, namely 2,2′‐azobisisobutyronitrile, cobalt(II) phthalocyanine pyridine complex and cobalt(II) tetraphenylporphyrin pyridine complex. T…
The Three Graces of Canova illustrates an assembly of three entities, each carrier of its own virtue, which become one in the embrace to the central figure, governing the unit composition. Similarly, the Ln3Q9 molecular framework assembles three different NIR-luminescent lanthanide ions, in which the central position…
In this paper, we have developed a simple, facile, and efficient approach to synthesize polyaniline fibers (PANI fibers) from aniline in the presence of (NH 4 ) 2 S 2 O 8 with sodium dodecyl benzene sulfonate (SDBS) and L-camphorsulfonic acid (L-CSA) as double templates. The chemical constituents of the composites are…
We present a new feature-based design concept for filter design in which a filter is designed specifically to image a known feature with dimensions lower than the optical resolution of the system. Unlike the conventional filter design based on focal spot engineering, we use the complete response of the microscope to f…
Abstract We present a first-principles density functional theory-based study about the impact of pressure on the structural and elastic properties of bulk CaN2, SrN2, and BaN2. Non-spin and spin polarized calculations indicate that the non-spin polarized ground state was more favourable with magnetic moments of 1.049…
Special Tm3+ transition and a bright green light emission is first observed in the Yb3+/Tm3+ co-doped KMnF3, which are synthesized by the molten salt synthesis method. The RGB light emissions are simultaneously obtained with a single Tm3+ activator, and white upconversion luminescence is observed only by changing the…
Temperature dependent optical reflectance measurements on well characterized samples of nonintentionally doped, Cr-doped, and V-doped ${\mathrm{Sb}}_{2}{\mathrm{Te}}_{3}$ show that both the parent compound and the Cr-doped version are narrow-gap semiconductors $({E}_{g}\ensuremath{\approx}0.25$ eV) with a conventional…
The stable 4 : 1 host–guest complex of phthalocyanine (Pc) and hydroxypropyl-beta-cyclodextrin was designed, computer modeled and prepared. The complex formation can greatly increase water solubility, reactive oxygen generation ability, biocompatibility and, thereby, the in vitro phototoxicity of Pc to cancer cells.
Supercapacitors are energy storage devices that make use of ion adsorption (electrochemical double layer capacitors) or fast surface redox reactions (pseudocapacitors). They complement batteries in electrical energy storage. Recent advances in charge storage mechanisms and the development of advanced nanostructured ma…

N-Doped meso-macroporous carbon materials were synthesized using melamine-formaldehyde resin as carbon precursor and silica spheres as a removable template. The as-synthesized carbon materials with a bimodal pores structure (about 3.9 and ∼50–200 nm) display a high surface nitrogen content of 30 wt %. The macropores o…
The half-metallicity and electronic structures for the bulk, surfaces and interfaces of zinc blende (ZB) NiO are investigated by using full potential linearized augment plane wave method with the modified Becke and Johnson potential. Obtained results reveal ZB NiO is half-metallic ferromagnet with half-metallic gap 0.…
Abstract The sulfonated bipyridine derivative disodium 6,6′‐bis(sulfonatomethyl)‐2,2′‐bipyridine [Na2(smbipy)] was synthesized, and its complexation behaviour towards divalent 3d metals in aqueous solution was explored. The complexes of late 3d metals [M(smbipy)(H2O)2]·H2O (M = Co, Ni, Zn) and [Cu(smbipy)(H2O)] are sp…
