    This Perspective describes the physical molecular driving forces that stabilize native lignocellulosic plant biomass structures and govern thermochemical biomass pretreatments. Understanding these driving forces can help us to design efficient methods for deconstructing biomass into biofuels and other bioproducts.

Perovskites for Optoelectronics

Perovskite materials have become very promising candidates for a new generation of potentially printable and efficient optoelectronic devices. Photovoltaic devices based on hybrid perovskites now achieve more than 20% photoconversion efficiency, and applications in solid-state lighting, photodetection and lasing are soaring. Their optoelectronic and photophysical properties are under intense scrutiny. This web-collection brings together a selection of multi-disciplinary research and comments published in the Nature journals that explores the basic properties of halide-based perovskite materials and their potential for application in optoelectronics, from solar cells to lasers. It serves to illustrate the road to easily processable and efficient devices by presenting both historical milestones and the crucial landmark studies published in the last 12 months in the Nature journals.
