This bright field image shows a spontaneous assembly of hexagonal Pd nanosheets with {111} facet exposed on carbon film. four and a half pieces of regular Pd hexagons stacked together by a face-to-face order, which can be clearly discerned in the false-colour strengthened image. the strong electron irradiation induced the formation of nanopores on the surface of the ultrathin nanosheets.

We applied electrical technology to control the gold nanoparticle deposition on working electrode. In our experiment, the shape of gold nanoparticle could be successfully controlled (e.g. sphere, flower, dumbbell, popcorn and triangle). In addition, we could also prepare same controlled nanoparticle cluster, such as leaves, seaweed and Christmas tree cluster structures which is shown on the image. This research will provide a reliable surface roughness technology to increase sensitivity of biosensors.

SEM micrograph of etched pearlite and micron-sized secondary phase precipitations – iron carbide (Fe3C) on the surface of high carbon steel. One inclusion was located on pearlitic phase surrounded by lamellar structures and another one was occupied along the grain boundary. This microstructure was achieved by ultra-high temperature confocal scanning laser microscope with controlled quenching rate (-60⁰C/min) on originated dual-phase (martensite and retained austensite) high carbon steel.
