  • A new study of samples from the Ryugu asteroid reveal a greater diversity of macromolecular organic matter than that found in related carbonaceous meteorites. Researchers find distinct populations of alkyl-aromatic grains, and organic carbonate is found with coarse-grained clay minerals

  • Supramolecular networks deposited on surfaces are of interest for a range of applications, but expanding monolayers to well-ordered multilayers remains a significant challenge, not least because analytical tools capable of probing such assemblies are limited. Here, the authors demonstrate that combining AFM-IR with STM enables an assessment of the differences in molecular conformations between 2D and 3D supramolecular networks adsorbed onto a HOPG surface.

  • There is an urgent need of cleaner and energy-efficient technologies for future sustainable chemicals and fuels. Here the authors report the gas phase synthesis of long hydrocarbon chains from atomic carbon and molecular hydrogen precursors in an inert carrier gas, avoiding the use of metal catalysts.

  • Visible-light-responsive photocatalysts can directly harvest energy from solar light. Stable conducting polymer nanostructures show high photocatalytic activity under visible light without using sacrificial reagents or precious metal co-catalysts.

  • The periodic organization of molecules on a solid substrate is attractive for a range of applications, but selecting the appropriate characterization technique that is suitable for both large area and accurate analysis at the nanoscale remains challenging. Here, the authors showcase the utility of infrared absorption microscopy in the unambiguous identification of complex molecular layers, directly observing isolated polyoxometalate-based nanoclusters dispersed on a substrate.
