  • Model thiophene-decorated nickel porphyrins are synthesized to examine how sulfur promotes CO2-to-CO conversion and tandem CO2-to-C2 product conversion in electrocatalytic CO2 reduction. Combined theoretical and experimental analyses show that thiophene substituents generate a ligand hole character that modulates the nickel-centred electronic structure, enhancing overall catalytic performance.

  • Manipulating the carbon-carbon coupling pathway in CO2 electroreduction is vital yet challenging. Here, by studying two model copper-based catalysts with distinct ethylene and ethanol selectivity, authors investigate the mechanistic origins for symmetric and asymmetric carbon-carbon coupling.

  • Conventional alkaline and neutral CO2-to-CH4 systems suffer carbon loss, and recovering the lost carbon requires input energy exceeding the heating value of CH4. Here, the authors report a chelating strategy to obtain Cu-N/O single sites decorated Cu clusters, which enables energy- and carbon-efficient CH4 electroproduction in an acidic system.

  • Copper is unique among CO2 electrocatalysts owing to its ability to produce multicarbon products at high rates; however, achieving selectivity for specific products remains challenging. Here, Cu surfaces decorated with alkaline earth metal oxides are found to strongly favour alcohols over hydrocarbons.

  • A novel dual-mode magnetic Fe3O4 nanoclusters was developed that exhibit efficient photothermal conversion and superparamagnetism. The particles served as numerous ‘nanoheaters’ in a PCR reaction mixture while enabling effective magnetic-based macromolecular manipulation. The thermal transfer between particles and adjacent water and DNA molecules thus become extremely efficient because of molecular-level proximity and allowed rapid amplification cycle progression. The defective mitochondrial DNA from cybrid cell lines of a patient with chronic progressive external ophthalmoplegia syndrome was efficaciously quantified by fluorescence intensity detection. Our finding provides new insight into rapid and accurate quantitative DNA diagnostics for future point-of-care applications.
