Solar energy is the most abundant source of energy available in our country. The power of the sun can be efficiently used to harness energy for solving our energy needs. The void of not having efficient technology to tap this abundant energy reservoir has led to search for better technologies and more varied applications. Our primary focus in this paper would be on utilizing solar energy for do...

Previously we had shown that ammonia stimulates nitric oxide (NO) synthesis in astrocytes by increasing the uptake of the precursor amino acid, arginine via the heteromeric arginine/glutamine transporter y⁺LAT2. Ammonia also increases the concentration in the brain of the endogenous inhibitor of nitric oxide synthases (NOS), asymmetric dimethylarginine (ADMA), but distribution of ADMA surplus b...

The ammonia-water film condensation is used as an efficient working fluid in industrial applications such refrigeration, plate condenser and evaporator, absorber/generator heat exchange, air-conditioning, pumps separation processes. present work focuses on a numerical investigation of water-ammonia falling binary liquid inside parallel by mixed convection. composed two vertical plates. One the ...

Three lignocellulosic pretreatment techniques (ammonia fiber expansion, dilute acid and ionic liquid) are compared with respect to saccharification efficiency, particle size and biomass composition. In particular, the effects of switchgrass particle size (32-200) on each pretreatment regime are examined. Physical properties of untreated and pretreated samples are characterized using crystallini...

Abstract Given the significant changes taking place in geopolitical global situation, and derived supply chain issues for some traditional electric propulsion propellants like xenon, alternative issue is perceived as a strategic topic to tackle, ammonia (NH3) becoming one serious candidate. Ammonia increasingly being investigated extend green hydrogen use by overcoming storage transportation of...

The behavior of several nand p-type semiconductors in liquid ammonia with 0.1 M KI as supporting electrolyte was investigated. The flat-band potentials were estimated from Schottky-Mott plots, and the current-potential curves with several redox couples (e.g., benzophenone, naphthalene, nitrobenzene) in the dark and under illumination were obtained. Photoinjection of solvated electrons at p-GaAs...

Dielectric constant and loss in liquid-ammonia solutions of alkali halides have been measured in the frequency range 0.7 — 70 GHz. At least one relaxation process exists in this frequency range in addition to the relaxation of the solvent molecules. The additional relaxation is ascribed to the orientational polarisation of ion pairs. The concentration of the ion pairs, calculated with a special...
