Effects of natural organic matter on aggregation kinetics of boron nanoparticles in monovalent and divalent electrolytes
منشور في 2010"…However, the attachment efficiency kept increasing in the presence of CaCl2 and alginate with the increase in the electrolyte concentration and was greater than unity at >4 mM CaCl2. The destabilization was attributed to bridging of the nanoparticles by the alginate–Ca2+ system. …"

A control algorithm to increase the efficient operation of wind energy conversion systems under extreme wind conditions
منشور في 2022"…<p dir="ltr">This paper aims to increase the power production of gearless permanent magnet synchronous generator (PMSG) based wind energy conversion systems (WECS) in strong (greater than 25 m/s) wind speed regions. In general, most wind turbines cut off when wind speed is over the cut-out rate; as a result, the power generation of the wind farm decreases. …"
