TL;DR: High-resilience positive-intrinsic-negative perovskite solar cells are demonstrated by incorporating a piperidinium-based ionic compound into the formamid inium-cesium lead-trihalide perovSKite absorber, and detailed degradation routes that contribute to the failure of aged cells are revealed.

TL;DR: It is shown that the band gap of MAPbBr3 crystals does not change due the presence of Bi3+ in the growth solution, and an increased density of states in theband gap and use of very thick samples for transmission measurements, erroneously give the impression of a band gap shift.

TL;DR: The highest azadirachtin content was recorded in the neem tree populations growing in the southern part of India and was found to be affected by climate and habitat.

TL;DR: Comparison between the left-running Fer expansion and the Magnus expansion indicates that the sign of the odd orders in Magnus may better be reversed if one would like to consider its effect in order.

TL;DR: Pulse sequences that implement sequential acquisition strategies on one and two radiofrequency channels with a combination of proton and carbon detection to record multiple experiments under magic-angle spinning are presented.
