Positively charged (cetylpyridinium chloride), negatively (sodium dodecyl sulfate), and non-charged (polyethylene glycol) surfactants are used as potential foulant in reverse electrodialysis systems supplying seawater river freshwater. Fouling tendency of the foulants to ion-exchange membranes is investigated terms adsorption by electromigration, electrostatic attraction, macromolecule interact...

In this study, the design of electric powered VTOL Flying car was made in CAD program, and longitudinal, vertical lateral flight dynamics were examined aerodynamic analysis made. design, power propulsion systems flying car, avionic systems, security magnetic sensors, navigation landing take-off methods, requirement verification performance values determined. Our work for cars, which will soon s...

Light sources with ultra-low energy consumption and high performance are required to realize optical interconnects for on-chip communication. Photonic crystal (PhC) nanocavity lasers one of the most promising candidates fill this role. In work, we demonstrate an electrically-driven PhC nanolaser threshold current 10.2 {\mu}A emitting at 1540 nm operated room temperature. The InP-based bonded on...
