in this work, the effect of presence of the sodium tripolyphosphate (stpp), as an inorganic salt, on improving the performance of polyamide (pa) thin layer membranes has been studied. characterization analyses confirmed the presence of the salt on the whole surface structure of the thin layer. different salt loadings resulted in different fluxes and cu (ii) rejections. the thin layer containing...

The conversion of sunlight into electricity using solar cells has attracted very much attention during the last decades. Solar energy is clean, abundant and renewable. Solar cells found applications in many different fields such as in calculators, solar lamps and even on spacecraft and satellites. Historically, conventional solar cells were built from inorganic materials. The efficiency of such...

Organic–inorganic interfaces exist in many natural or synthetic materials, such as mineral–protein interfaces found in bone and epoxy–silica interfaces found in concrete construction. Here, we report a model to predict the intrinsic strength between organic and inorganic materials, based on a molecular dynamics simulation approach combined with the metadynamics method, used to reconstruct the f...

There is a lot of thrill in a new area of research called Nanotechnology. The term nanotechnology describes a range of the technologies performed on a nanometer scale with widespread applications. Lot of research has been going on in finding nanomaterials. An area of research under this field is Nanocomposites. They are material made by mixing of two different materials (with different properti...

The MODAR process uses supercritical water, heated above 374OC and pressurized above 220 atm, as a medium for the rapid and complete oxidation of organic compounds to carbon dioxide, water and inorganic salts. The destruction efficiencies achieved exceed 99.99% for a wide range of compounds including chlorinated solvents and PCB’s. The exothermic oxidation reaction produces sufficient energy to...

Green hydrogen, produced using solar energy, is a promising means of reducing greenhouse gas emissions. Photoelectrochemical (PEC) water splitting devices can produce hydrogen sunlight and integrate the distinct functions photovoltaics electrolyzers in single device. There flexibility degree integration between these electrical chemical energy generating components, so plethora archetypal PEC d...

Organic-inorganic hybrid perovskite solar materials, being low-cost and high-performance, are promising for large-scale deployment of the photovoltaic technology. A key challenge that remains to be addressed is the toxicity of these materials since the high-efficiency solar cells are made of lead-containing materials, in particular, CH3NH3PbI3. Here, based on first-principles calculation, we se...
