Electrodes at commercial forefronts
Abstract: Electrodes at commercial forefronts describe self sustenance approaches in place of traditional cent percent dependence on fissile fuels. Application of solid oxide fuel cells in developed multi-electrode systems have employed in cases of power shortages at nano-material designs. Nano-materials have large surface area but introduced problems such as poor electrode packing densities, high electrolyte reactivity, and expensive synthesis procedures. Thermal stress assisted electrolytic decomposition has motivated use of high temperature …

Solubility Enhancement of Theophylline Drug Using Mixed Solvency Approach
Abstract: “Solubility enhancement” is one of the difficult tasks that have become a great challenge in formulation development of orally administered drugs having poor aqueous solubility. Poor aqueous solubility of drugs creates significant problems in producing formulations of sufficiently high bioavailability, thereby preventing the effective usage of these drugs. With the introduction of the concept of “mixed-solvency,” it is feasible to increase the solubility of poorly water-soluble drugs in aqueous solutions …
