    Picoscale engineering of bonds is a powerful method to tune materials properties. Transcending nanoscience, picoscience offers the ultimate length scale to manipulate materials through subtle bond distortions between individual atoms, as this Review discusses through several examples ranging from perovskites to superconductors and to topological materials.

    Tuning the surface strain in multimetallic nanomaterials represents an effective strategy to improve their electrocatalytic properties. In this Review, using the oxygen reduction reaction as a model, the underlying relationship between surface strain and catalytic activity is discussed, along with the introduction, tuning and quantification of strain in nanocatalysts.

    Singlet exciton fission is a carrier multiplication process in organic semiconductors that could be used to enhance the efficiency of conventional inorganic solar cells and break the Shockley–Queisser limit of single-junction photovoltaics. In this Review, recent progress in the field is assessed, highlighting the key results and identifying the crucial challenges ahead.
