Size Effect on Photothermal Heating Ability of Gold Bipyramids
Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...
