    Nanoscale semiconductor materials have large tolerance to lattice mismatches, which enables an almost arbitrary control of alloy composition and bandgap energy. In this Review, semiconductor alloy nanomaterials are examined, and their synthesis, properties and potential for applications — such as lasers, solid-state lighting and solar cells — are discussed.

    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.
