This collection celebrates 15 years of research on covalent organic frameworks and highlights some of the contributions that were published in journals of the Nature Research portfolio. We hope you enjoy exploring these snippets on the synthesis and structure of COFs, their physical properties, and their application in fields encompassing energy, catalysis, storage and separation.
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.
To mark the 150th anniversary of the chart that has come to symbolize the field of chemistry, 2019 has been declared to be the International Year of the Periodic Table of Chemical Elements by the United Nations. We join the celebrations with a collection of articles that explore elements on — and off — the table.
Encoded chemical libraries can be used to screen a vast array of compounds against a protein target to identify potent binders. A collection of articles in this focus looks at different methods to create libraries of encoded peptide macrocycles and the advantages that such libraries offer for discovering protein binders.
Efficient redox catalysis offers an important avenue in using renewable energy to process fuels. To this end, efforts in homogeneous, heterogeneous and microbial catalysis may each advance our fundamental understanding and technological capabilities.
Our understanding of the bonding, reactivity and electronic structure of actinides, though it has both fundamental and practical importance, lags behind that of the rest of the periodic table. A collection of articles in this Focus highlights recent developments in this area, in particular featuring uranium(VI) dianions bearing four U–N multiple bonds, berkelium(IV) stabilized in aqueous solution and a plutonium material showing evidence for the delocalization of 5f electrons.
