Increases in motor efficiency that would result from the use of copper motor rotors are projected to result in total energy savings in the year 2010 of 20.2 E+12 Btu/y if the new motors gain only a 10% market penetration. Savings would rise to 143 E+12 Btu/y at the expected market penetration of 50 to 70%. (Figures vary because increases in ...

Cu doping is a simple and effective approach to render NiOx a promising HTL for high-performance perovskite solar cells due to the improved elec. cond. and favorable perovskite crystn. As a result, losses in Jsc and FF in the pristine NiOx-based devices are mitigated, and a high PCE of up to 15.40% with good environmental stability are obtained.

Introduction. High temperature ceramic solid oxide fuel cells (SOFCs) are well-known electrochemical devices that directly convert, in a very efficient way, the chemical energy of hydrogen-enriched fuels, including hydrocarbons, into electricity and heat power (Singhal and Kendall, 2003; Cooley, 2009).They are promising energy conversion devices due to their fuel flexibility, good electricity ...

Jul 02, 2021 During the spin-coating process, while DMSO leaves the film, it can be expected that BAAc is retained due to its high boiling point and ionic state. Furthermore, BAAc, with its high boiling point, is challenging to volatilize at an annealing temperature of 100 C entirely.

Jun 01, 2020 The purification process proposed in this work was achieved by high-efficiency extraction with two-phase solvents, water and n-hexane, considering that ODA is used as organic surfactant for Cu NWs. ODA, as the organic surfactant of Cu NWs, was added specifically to manipulate the shape of the nanocrystals into NWs.

Feb 19, 2020 But this study found that the actual performance of nutrients recovery by pure magnesium oxide power was not as high-efficiency as expected. The reason is probably that struvite tends to crystallize on the surface of MgO power, thus hinders the hydrolysis and release of internal Mg 2+. Otherwise, MgO power easily dissolves in the slightly ...
