Organometal halide (OMH) perovskites are highly promising for photovoltaic (PV) and other applications. However, their instability toward environmental factors such as humidity presents a major challenge in potential commercial use. In this study, we developed method to modify the surface of CH3NH3PbI3 perovskite films by spin coating oleic acid (OA) create water resistant layer that results enhanced stability PV performance. The OA-surface passivated were studied using FT-IR spectroscopy,...
A unique natural polymer based colon specific drug carrier was prepared from carboxymethyl cellulose (CMC) and acrylic acid (AAc) in aqueous solution employing γ‐radiation induced copolymerization crosslinking. The effect of preparation conditions such as the content irradiation dose on gelation process investigated. swelling behavior hydrogels characterized by investigating time pH dependent (CMC/AAc) different CMC content. effects hydrogel composition medium indices were estimated. results...
Abstract A series of functional copolymer hydrogels composed carboxymethyl cellulose (CMC) and 2‐acrylamido‐2‐methyl propane sulfonic acid (AMPS) were synthesized using γ‐radiations‐induced copolymerization crosslinking. Preparation conditions optimized, the swelling characteristics investigated. The ability prepared to recover some toxic metal ions from their aqueous solutions was studied. hydrogel showed a great capability such as: Mn +2 , Co Cu Fe +3 solutions. data revealed that...
Problems resulting from gas emissions lead to increase the concern about safety and health issues with demand reduce marine shipping. Marine power plants are considered as one of greatest contributors in pollutants around world. Waste heat recovery systems when implemented ship propulsion system can emissions, fuel consumption improve overall efficiency generation utilization. The present article describes waste technology potential for operators lower costs, exhaust effect on EEDI ship....
Abstract A new carrageenan based chelating copolymer sorbent was prepared by gamma radiation induced copolymerization and crosslinking of kappa‐carrageenan (k‐Car) acrylic acid (AAc). The swelling characteristics the were investigated studying effect time, pH, ionic strength medium. sorption capacities for Fe, Pb, Mn, Zn, Cu, Sr, Cd, Al 172, 202, 216, 221, 230, 239, 244 mg/g respectively. Freundlich Langmuir adsorption isotherms used to validate metal uptake data heats ions calculated....
Copolymer films of Acrylic acid/ Methyl methacrylate AAc/MMA with comonomer composition 60/40 was prepared and then irradiated by gamma irradiation. The effect irradiation on some the physical properties copolymer investigated. dose level ranged from 5 to 200 kGy. thermo gravimetric analysis (TGA) showed that thermal stability increased up 100 kGy it started decrease. results UV-Visible spectroscopy a decrease in values optical band gap tail width doses starting DC conductivity (?DC) found...
