  • Single-atom Fe–N–C catalysts are the most promising alternative to Pt-group metal catalysts for the cathodic oxygen reduction reaction in fuel cells, but while the chemical environment of their active centres is well understood, their electronic structure remains elusive. Now, using molecular model catalysts, a high-spin trivalent FeN4 site with an axial hydroxyl ligand is identified as the active site in Fe–N–C catalysts.

  • Probing inevitable defects in two- dimensional materials is challenging. Here, the authors tackle this issue by using tip-enhanced Raman spectroscopy (TERS) to obtain distinctly different Raman features of edge defects in atomically thin MoS2, and further probe their unique electronic properties as well as identify the armchair and zigzag edges.

  • Revealing the spatial distribution of hot carriers in real space is crucial to their efficient utilization. Here, the authors show that in-situ electrochemical tip-enhanced Raman spectroscopy is able to resolve the spatial distribution of reactive hot carriers with a nanometer spatial resolution.

  • Characterization of dynamic conformational changes in membrane protein complexes by NMR spectroscopy remains challenging. Here authors report the site-specific incorporation of 4-trimethylsilyl phenylalanine (TMSiPhe) into proteins, which enabled the characterization of multiple conformational states of a phospho-β2 adrenergic receptor/β-arrestin-1 complex in response to different receptor ligands.

  • Plasmon-enhanced Raman spectroscopy (PERS) is a highly sensitive technique that can provide molecular fingerprint information. This Technical Review discusses the fundamental principles, advantages and limitations of PERS, key issues in using PERS and interpreting results, and state-of-the-art applications in materials characterization, bioanalysis and the study of surfaces.
