These tiny combs were made inside a furnace at about 1250 degrees Celsius. Commercial zinc oxide powder, which was heated at about 1400 degrees Celsius, was used as the source material. This picture was taken inside a field emission gun scanning electron microscope at 1200x magnification.Scanning electron microscopy (SEM) image of aligned ZnO nanowire arrays synthesized by a vapor-solid process. The source materials used for the synthesis were commercial ZnO, SnO2 and graphite powders, which were placed in a tube furnace. By heating the source materials to a high temperature, reduction of Sn from SnO2 occurred, which served as the catalyst for the growth of ZnO nanowires. This material is the fundamental structure for biosensing, manipulation of cells, electron field emission, and converting mechanical energy (such as body movement, muscle contraction, heart beating, blood flow..) into electricity for powering nanodevices.Electron microscope image of a mirid bug.Scanning Electron Microscope (SEM) photomicrograph of TephaFLEX® Surgical Mesh (magnification 15X).

The ‘fibre’ which can be readily identified as a softwood tracheid due to the presence of four bordered pits.This microscape image was digitally stitched together from multiple (FEI) field emission gun scans or more commonly know (SEM)Scanning Electron Microscope scans. The base surface in this picture is made of highly aligned, dense zinc oxide nanorods, which were grown inside a tube furnace system by oxidizing zinc foil at temperature of 500-600 Celsius degree. The higher, complex structures are also made from zinc oxide, which were grown from by absorbing the reactants from the vapor.
