Absolute total cross section (TCS) for electron scattering from hexafluoroacetone (HFA: (CF3)2CO) molecules has been measured from 1 to 400 eV, employing a linear electron-transmission technique. The TCS energy function for the electron–HFA collision has two broad enhancements: the first, visible between 2 and 28 eV,…
Abstract A novel inorganic‐organic hybrid compound [Cu2(TTHA)(bpy)2(H2O)]2·6H2O (TTHA = 1,3,5‐triazine‐2,4,6‐ triamine hexaacetic acid; bpy = 2,2′‐bipyridine) was synthesized and characterized. The compound crystallizes in the triclinic space group P$\bar{1}$ with cell dimensions of a = 10.4837(14) Å, b = 13.0935(17)…
The next great wave of innovation and development for implantable medical devices focuses on surface engineering. This would enhance their performance, restore lost functions and ultimately reduce pain. Biomimetic coating is a promising approach, used in that concern. In the present work, an attempt was made to develo…
Loading–unloading curves obtained from indentation experiments can be used to extract elastic-plastic mechanical properties using the finite element (FE) method. However, extensive computation times are required in such an approach due to the fact that the optimization procedure is based on iterative FE computations.…
We report a study on the low-temperature heat transport of the Ba${}_{3}$Mn${}_{2}$O${}_{8}$ single crystal, a layered spin-dimer compound exhibiting the magnetic-field-induced magnetic order or the magnon Bose-Einstein condensation. The thermal conductivities ($\ensuremath{\kappa}$) along both the $ab$ plane and the…
A brief summary of the Indian research and development activities related to Thorium utilization for sustainable supply of nuclear energy is provided in this paper.
The dissolution of seven natural limestones and calcareous rocks in hydrochloric acid solution was examined to investigate their capability for wet flue gas desulphurisation. All samples were crushed, ground and sieved to a size‐fraction of 150–250 µm. Thereafter they were subjected to a dissolution experiment utilisi…
BACKGROUND: Based on growing evidence that some adult multipotent cells necessary for tissue regeneration reside in the walls of blood vessels and the clinical success of vein wrapping for functional repair of nerve damage, we hypothesized that the repair of nerves via vein wrapping is mediated by cells migrating from…
A new tetradentate tetraaza ligand was prepared via Schiff-base condensation of 3,4-diaminotoluene with 2,3-butandione monoxime in aqueous solution. This ligand coordinates cobalt(III) through nitrogen donors in equatorial positions with loss of one oxime proton with concomitant formation of an intramolecular hydrogen…
Radomes usually used for protection of antennas from environment should have minimum degrading effects on antenna performances. Recently, metamaterials are used in radome designs to improve their characteristics. In this work, various combinations of omega type metamaterial are investigated in planar radome designs. T…
Aqueous extract of Massularia acuminata root at the doses of 50, 100 and 200 mg kg(-1) body weight was investigated for its effect on sexual behaviour in male Wistar rats. Phytochemical screening revealed the presence of alkaloids, anthraquinones, saponins, phenolics, flavonoids and tannins in the extract. The increas…
Nanotechnology remains the field to explore in the quest to enhance therapeutic efficacies of existing drugs. Fabrication of a methacrylate copolymer-lipid nanoparticulate (MCN) system was explored in this study for oral drug delivery of levodopa. The nanoparticles were fabricated employing multicrosslinking technolog…
In this work, the reliability of an embedded planar capacitor with epoxy-BaTiO3composite dielectric was investigated under temperature-humidity-bias (THB) conditions. The temperature and humidity conditions were selected as 85°C and 85% RH, respectively. In order to investigate the effect of an applied bias, one set o…
Improvement of pattern placement accuracy is essential to solve upcoming challenges in mask making. Placement errors are driven by multiple effects with electron mediated resist surface charging being a major error source. Modeling this systematic effect thus allows the determination of the placement errors before pla…
We develop a fully microscopic, statistical mechanics approach to study phase transitions in Ising systems with competing interactions at different scales. Our aim is to consider orientational and positional order parameters in a unified framework. In this paper, we consider two-dimensional stripe-forming systems, whe…
Nanocrystalline Eu(3+), Tb(3+) co-doped Lu(2)O(3) powders with a maximum size of 25.5 nm were prepared by the sol-gel process, using lutetium, europium and terbium nitrates as precursors, and ethanol as a solvent. Differential thermal analysis (DTA) and infrared spectroscopy (IR) were used to study the chemical change…
The influences of temperature, dopant density, free-carrier density, and field orientation on the electron drift mobility and velocity-field relationship in wurtzitec-axis GaN are quantified by means of theoretical investigation. Electron velocity perpendicular to the growth plane is uniformly lower than that parallel…
Abstract The long-term atmospheric corrosion behavior of extruded aluminum alloy 7075-T6 (UNS A97075) was investigated by weight loss, corrosion morphology, loss in mechanical properties, and corro...
A series of six self-propagating molecular assemblies (SPMAs) were generated by alternative solution-deposition of ruthenium polypyridyl complexes and d8palladium and platinum salts on glass and silicon substrates. The d6 polypyridyl complexes have three pyridine units available for forming networks by coordination to…
We analyze the ultrahigh-resolution laser angle-resolved photoemission spectroscopy intensity from the slightly underdoped Bi${}_{2}$Sr${}_{2}$CaCu${}_{2}$O${}_{8+\ensuremath{\delta}}$ in the superconductive (SC) state. The momentum distribution curves were fitted at each energy $\ensuremath{\omega}$ employing the SC…
