  • Selective oxidation of biomass-derived precursors has been reported but requires elevated temperatures and pressures of O2 and strongly alkaline conditions. This study develops an antenna–reactor plasmonic photocatalyst (RuPt on TiN) for the selective conversion of HMF to FDCA using near-infrared irradiation in the absence of base.

  • Precision agriculture requires scalable, low-cost sensor technologies capable of delivering real-time, high-resolution insights into soil, plant, and environmental conditions. Here, the authors review printable materials and devices in enabling real-time and continuous monitoring for smart agriculture.

  • Upcycling glycerol can substantially contribute to circular carbon economy. Here, an amino acid-functionalized graphene organocatalyst with high acidity converts glycerol and biooil wastes into high-value chemicals and fuels, even at low temperatures, advancing the state-of-the-art in sustainable carbon valorization technologies and circular economy.

  • Development of strategies for the synthesis of pi-conjugated polymers is hampered by limited solubility. Here, the authors report a synthetic protocol based on the search for specific vibrational modes through an appropriate tailoring of the p-conjugation of the precursors, in order to increase the attempt frequency of a chemical reaction.

  • Molecules can change their electronic properties when they are adsorbed on substrates, which can be useful for sensing and catalysis. Here, the authors use atomic force microscopy to show that the spin state of an iron complex can be changed upon displacing the molecule to different sites of a nitrogen-doped graphene

  • Developing room-temperature magnets from materials containing onlysporbitals has remained an elusive but important goal. Here, Zbořil and co-workers report hydroxofluorographenes that exhibit room-temperature antiferromagnetic ordering and low-temperature ferromagnetic behaviour with high magnetic moments.

  • Phosphates are fundamental building blocks of ribonucleic acids and excellent catalysts for proton transfer reactions. Here, the authors report that the combination of the catalytic effect of phosphates with the entropic effect of crystallization can be exploited to facilitate formation of oligopeptides from the crystalline salts of phosphoric acid with amino acids under mild conditions.
