  1. A Nanosized Silica Sunflower This SEM image represents an inorganic but vivid silica SUNFLOWER prepared by microwave plasma CVD. Take a look at the 100-nm-long white scale bar beneath the picture, and you will be surprised at how tiny this sunflower is. The sunflower-like morphology can be attributed to the unique assembly of one-dimensional silica (SiOx) nanowires which have very large aspect ratios because of the vapor-liquid-solid (VLS) growth mechanism. The picture was provided by Dr. Ming-Shien Hu who did the CVD experiment in 2004 at Advanced Materials Laboratory led by Drs. Li-Chyong Chen (CCMS, NTU) and Kuei-Hsien Chen (IAMS, Academia Sinica). Submitter & Editor: Dr. Chia-Liang Sun (Institute of Atomic and Molecular Science, Academia Sinica, Taipei, Taiwan; E-mail: clsun@ms.ntu-ccms.ntu.edu.tw) (First Prize Award in the art contest of American Vacuum Society, Seattle, 2007)
