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.
This collection of primary research articles, reviews and protocols focuses on an emerging topic of mechanobiology, highlighting the broad involvement of mechanical forces in different biological contexts, their roles in development, physiology and disease, and how these forces are sensed and transduced to produce biologically-relevant responses. The collection also showcases new technical approaches to modulate mechanobiology, which in the future could be used to control cell fate and behaviour for therapeutic benefits.
In health and biomedical applications, electronic technologies allow monitoring, sensing and extracting physiological data as well as correcting or supporting tissue function through electrical stimuli. This collection highlights the recent developments in materials science, electronics and biology of bioelectronic devices.
