TL;DR: Based on the chemical stability of group IV and V elements in acidic solutions, TaOx nanoparticles prepared by electrodeposition in an ethanol-based Ta plating bath at room temperature were investigated as novel nonplatinum electrocatalysts for the oxygen reduction reaction (ORR) in polymer electrolyte fuel cells (PEFCs) as discussed by the authors.

TL;DR: Nickel oxide and mixed-metal oxide structures were fabricated by using microwave irradiation in pure water to create unique rose-shaped nanostructures that exhibited promising performance as nanocatalysts for CO oxidation and in energy storage devices.

TL;DR: The findings of this work identify soft annealing as a critical parameter for the processing of chemically derived thin-film transistors, and it correlates device performance to the changes in material structure induced by softAnnealing.

TL;DR: In this paper, the authors measured the zeta potential of carbonate particles at different ionic content and aging times and found that the ionic properties affect the surface potential of these particles.

TL;DR: In this article, the authors report photolithographically defined n-type TFTs (n-TFTs) based on cadmium sulfide (CdS) films deposited using solution-based techniques.
