In the future, delivering therapeutic drugs exactly where they are needed within the body could be the task of miniature robots. Not little metal humanoid or even bio-mimicking robots; think instead of tiny bubble-like spheres.
By controlling the structural architecture of copper at the nanoscale, researchers could precisely shape the copper into nanoclusters under 2 nm in diameter, thereby enhancing the efficiency of its use as a catalyst.
Applied to a polycrystalline catalyst, the technique allows the visualisation of crystal grains, grain boundaries and defects - key factors dictating catalyst performance.
New technique guides liquid metal through microscopic channels to create flexible electronic circuits, offering simplified manufacturing of 3D conductive structures.
