A density functional study on equilibrium geometries, stabilities and electronic properties of Au5Li binary clusters

All electron scalar relativistic calculations have been performed to investigate the electronic structures of isomeric Au5Li binary clusters at the BLYP/DNP level of theory. The properties of these clusters are compared with the pristine Au6 clusters. As in case of the pure Au6 cluster, the minimum energy structure of the bimetallic Au5Li cluster is triangular with the lithium...

Over-Expression of Superoxide Dismutase Ameliorates Cr(VI) Induced Adverse Effects via Modulating Cellular Immune System of Drosophila melanogaster

The evolutionarily conserved innate immune system plays critical role for maintaining the health of an organism. However, a number of environmental chemicals including metals are known to exert adverse effects on immune system. The present study assessed the in vivo effect of a major environmental chemical, Cr(VI), on cellular immune response using Drosophila melanogaster and...

Nanotwinning and structural phase transition in CdS quantum dots

Nanotwin structures are observed in high-resolution transmission electron microscopy studies of cubic phase CdS quantum dots in powder form by chemical co-precipitation method. The deposition of thin films of nanocrystalline CdS is carried out on silicon, glass, and TEM grids keeping the substrates at room temperature (RT) and 200°C by pulsed laser ablation. These films are then...

Radionuclides and Radiation Indices of High Background Radiation Area in Chavara-Neendakara Placer Deposits (Kerala, India)

The present paper describes a detailed study on the distribution of radionuclides along Chavara – Neendakara placer deposit, a high background radiation area (HBRA) along the Southwest coast of India (Kerala). Judged from our studies using HPGe gamma spectrometric detector, it becomes evident that Uranium (238U), Thorium (232Th) and Potassium (40K) are the major sources for...

Influence of Cobalt Doping on the Physical Properties of Zn0.9Cd0.1S Nanoparticles

Zn0.9Cd0.1S nanoparticles doped with 0.005–0.24 M cobalt have been prepared by co-precipitation technique in ice bath at 280 K. For the cobalt concentration >0.18 M, XRD pattern shows unidentified phases along with Zn0.9Cd0.1S sphalerite phase. For low cobalt concentration (≤0.05 M) particle size, d XRD is ~3.5 nm, while for high cobalt concentration (>0.05 M) particle size...

Copper Nanoparticles in Ionic Liquid: An Easy and Efficient Catalyst for Selective Carba-Michael Addition Reaction

In this paper, we wish to report a novel synthesized copper nanoparticles in an ionic liquid employed as a catalyst for Michael addition between active methylene compound and α, β-unsaturated compounds to give corresponding compounds in excellent yield and in shorter reaction times.

Gas Chromatographic Retention Indices of Fentanyl and Analogues

Narcotic analgesics of the fentanyl class are characterized by high potency and relatively short duration of action. These compounds nowadays have become a substitute for heroine and are highly addictive for abusers. Herein, we report retention indices of fentanyl and its eighteen analogues relative to the homologous n-alkane series. These values are determined on a moderately...

Severe hypotension and overflowing of venous reservoir at the initiation of cardiopulmonary bypass in a patient undergoing repair of ruptured sinus of Valsalva aneurysm: management issues

Aneurysm of sinus of Valsalva is a rare cardiac lesion that may be acquired or congenital. The presentations of RSOV range from incidental detection to frank heart failure. Right sinus of Valsalva aneurysm usually ruptures into the right ventricle. If non-coronary sinus is involved, most aneurysms erode into the right atrium. The problems described with surgical repair of RSOV...

Removing the Threat of Diclofenac to Critically Endangered Asian Vultures

Veterinary use of the nonsteroidal anti-inflammatory (NSAID) drug diclofenac in South Asia has resulted in the collapse of populations of three vulture species of the genusGyps to the most severe category of global extinction risk. Vultures are exposed to diclofenac when scavenging on livestock treated with the drug shortly before death. Diclofenac causes kidney damage, increased...
