TL;DR: This transient absorption (TA) mechanistic study provides strong evidence that the improved electrical properties of oxygen-deficient TiO2 enables remarkably efficient spatial separation of electron–hole pairs on the submicrosecond time scale at moderate applied bias, and this coupled to effective suppression of microsecond to seconds charge carrier recombination is the primary factor behind the dramatically improved photoelectrochemical activity.

TL;DR: In this paper, the authors demonstrate that atomically thin layers of MoS2 and WS2 nanosheets can oxidize water to O2 under incident light and demonstrate that charge carrier lifetime is tailorable in atomically-thin crystals by creating heterojunctions of different compositions and architectures.

TL;DR: In this article, a lower limit for the required lifetime of holes for water oxidation on WO3 was provided by measuring the decay of photoholes on the milliseconds to seconds time scale in the presence of an electron scavenger.

TL;DR: In this article, the impact of moisture-induced chemical degradation and proton-lithium exchange on the Li-ion dynamics in the bulk and the grain boundaries and at the interface with lithium metal in highly Li-conducting garnet electrolytes is provided.

TL;DR: In this paper, the role of the dopant distribution in determining the critical current density for dendrite formation was investigated and the importance of controlling the dopants distribution in the garnet structure was highlighted.
