CsPbI3 nanowires undergo a structural phase transition from the yellow non-perovskite phase to the black perovskite phase during rapid thermal quenching. Perovskite phase CsPbI3 nanowires exhibited good optoelectronic properties for photovoltaic applications.

The development of high-performance and low-cost oxygen reduction and evolution catalysts that can be easily integrated into existing devices is crucial for the wide deployment of energy storage systems that utilize O2-H2O chemistries, such as regenerative fuel cells and metal-air batteries. Herein, we report an NH3-activated N-doped hierarchical carbon catalyst that exhibits good performance for both the oxygen reduction reaction and the oxygen evolution reaction, as demonstrated by means of electrochemical studies of its integration into the oxygen electrode of a regenerative fuel cell, and through theoretical calculation using density functional theory.

We develop a facile graphene-misorientation strategy to obtain angle-confined graphene bicrystals that contain only two lattice orientations with a tilt angle of 30°. The size of each graphene domain before coalescence is tuned from sub-centimeter (6 mm) to micrometer size using an efficient cooperative passivation strategy with a high growth rate.

Tumor oxygenation, measured by in vivo photoacoustic imaging and ex vivo immunofluorescence staining, was markedly improved by the intravenous administration of liposomes co-loaded with the photosensitizer hydrophobic chlorin e6 and the diabetes drug, metformin. Subsequently, the therapeutic efficacy of in vivo photodynamic treatment using the liposomes was shown to be superior to that of conventional photodynamic therapy without metformin.

We report the rational design of a catalyst for the oxygen reduction reaction with highly active catalytic centers and enhanced active site accessibility. The catalyst was obtained via a facile Prussian blue nanoparticle approach and displayed outstanding catalytic activity on par with the state-of-the-art Pt/C catalyst at the same mass loading in alkaline media, good performance in acidic media, and excellent stability and crossover tolerance.
