A new propulsion method for metallic micro- and nano-objects has been developed. The process is based on the novel concept of bipolar electrochemistry: under the influence of an electric field, one ...
Scientists are smashing metallic micro-cubes to make them ultrastrong and tough by rearranging their nanostructures upon impact. The team reports that firing a tiny, nearly perfect cube of silver onto ...
Ultralight (less than 10 milligrams per cubic centimeter) cellular materials are desirable for thermal insulation; battery electrodes; catalyst supports; and acoustic, vibration, or shock energy ...
