Abstract: The large photogalvanic effect photocurrent is desirable in noncentrosymmetric materials, which may promote practical applications in optoelectronic devices. Here, based on the quantum transport simulations, we propose that the maximum photocurrent of recent attractive Te-based… read more here.

DOI: 10.3390/molecules27092686
Abstract: Commercialization of anion exchange membrane fuel cells (AEMFCs) has been limited due to the chemical degradation of various quaternary ammonium (QA) head groups, which affects the transportation of hydroxide (OH−) ions in AEMs. Understanding how… read more here.
