We report the temperature dependence of the low-temperature specific heat down to 400 mK of the electron-doped Ba(Fe 0.92 Co 0.08 ) 2 As 2 superconductors. We have measured two samples extracted from the same batch: first sample has been measured just after preparation with no additional heat treatment. The sample sho…

Metal jet emission and weld interface formation in impact welding were investigated for similar- and dissimilar-metal lap joints. Numerical simulation of oblique collision between metal plates was performed using smoothed particle hydrodynamics (SPH) method for various plate thicknesses, collision velocities, and coll…
The aim of the present paper was to obtain new solid forms of Norfloxacin. For this purpose Norfloxacin was recrystallized from: acetic acid and its mixtures with several organic solvents. By recrystallization of Norfloxacin from acetic acid and from its mixture with several organic solvents a new solvate was found. T…
The Hall effect, the anomalous Hall effect (AHE) and the spin Hall effect are fundamental transport processes in solids arising from the Lorentz force and the spin-orbit coupling respectively.The AHE, in which a voltage transverse to the electric current appears even in the absence of an external magnetic field, was f…
The goal of the present investigation was to formulate and evaluate chitosan nanoparticles of temoxifen citrate for cancer therapy. Nanoparticles of TMX were prepared using chitosan using ionic gelation method. The concentration of the polymers Chitosan were selected based on the results on preliminary screening. The…
The effect of the strain rate, stress triaxiality and temperature on the fracture properties of Ti6Al4 V is studied. First, static and dynamic in-plane tensile, shear and plain-strain tests are carried out. Classical measurements are combined with full field strain measurement by means of digital image correlation to…
Cadmium chalcogenides with appropriate band gap energy have been attracting a great deal of attention because of their potential applications in optoelectronic devices. CdS in the form of thin films is prepared at different substrate by a simple and inexpensive chemical bath deposition technique. The as deposited thin…
The antimicrobial effects of silver (Ag) ion or salts are well known. Recently, silver nanoparticle is attracting an interest in a wide variety of fields since it has been known to be safe and effective as an antimicrobial agent against a broad spectrum of microorganisms. Although silver nanoparticle has been applied…
A recognized safety issue for future fusion reactors fueled with deuterium and tritium is the generation of sizeable quantities of dust. Activated dust mobilization during a Loss of Vacuum Accidents (LOVA) is one of the safety concerns for the International Thermonuclear Experimental Reactor (ITER). Intense thermal lo…
We report reactivity of silicon doped single walled carbon nanotube (Si-CNT) towards the small atmospheric gas molecules O 2 , CO 2 , SO 2 and NO 2 using density functional theory based on the numerical basis set method. The reactivity of gas molecules is explained with binding energy, band structure, charge density,…
Nd 3+ strengthens the Er 3+ :2.7-m emission 10 4 times in fluorophosphate glass; in addition, it can also decrease its upconversion effects and the 1.5-m emission accordingly. Cross-relaxation process is the principal transition mechanism in this codoping system. Compared with Er 3+ singly doped glass, J-O parameters…
Calotropis gigantea Linn. (Asclepiadaceae) a widely growing plant has been reported to possess number of medicinal properties. The purpose of the present study was to evaluate scientifically the anticonvulsant activity of Petroleum ether, Benzene, Chloroform, Methanol and Aqueous extract of leaves of the plant C.gigan…
In this paper the behavior of positive charge formed in the vicinity of the Semi-conducting sheet anode at room temperature and under applied dc has been investigated just after the reversal of the sample, and when the sample was combined with another sample without pre-stressing using the pulsed electro acoustic (PEA…
Spherulitic morphology of pure poly lactic acid (PLLA) PLLA have investigated after thermal annealing. The morphology of spherulite of pure poly lactic acid (PLLA) PLLA have investigated after thermal annealing. The effect of both annealing temperature and crystallization temperature on the formation of cracks was des…
Tubular frameworks of a tetrathiafulvalene (TTF) based electron-donor with a N1-phenyluracil moiety were constructed by strong self-assembling abilities. The uracil moiety formed the reversed Watson–Crick type hydrogen-bond pair. The TTF moiety exhibited C–H⋯X hydrogen-bonds, S⋯S interactions, and uniform π-stack. The…
A cavity resonator in the shape of a prism with a square base and walls that are either perfect electric or perfect magnetic conductors is considered. The resonator consists of two identical prisms with triangular bases, filled respectively with a double-positive material and a double-negative metamaterial, the two ma…
The TM0 surface mode in an infinitely long parallel-plate waveguide filled with a double-positive (DPS) and epsilon-negative (ENG) metamaterial bi-layer is studied. With proper constitutive parameters and thicknesses of the two layers, the slow-wave factor (SWF) for such a parallel-plate waveguide can tend to infinity…
Abstract The objective of this work is to present a comparative study of the behaviour of a polymer composite before and after accelerated ageing with exposure to UVB radiation and water vapour. The goal is to propose a methodology to characterise material ageing by observing its phenomenological behaviour without tak…
We studied the optical absorption and photoconductive properties of thin films consisting of core-shell octapod-shaped nanocrystals, which consisted of CdS pods that branch out from a CdSe core. The current-voltage characteristics were measured at room and cryogenic temperatures and agreed well with a phenomenological…
