英文摘要	Direct fabrication of uniform patterns of Fe2O3 center dot xH(2)O nanoparticles on the SiOx/Si surface was achieved by microcontact printing (mu CP). The as-prepared poly( dimethylsiloxane) ( PDMS) stamps with a hydrophobic surface were used. The "ink" was an FeCl3 center dot 6H(2)O ethanol solution. Fe2O3 center dot xH(2)O nanoparticles were formed on the stamps from the hydrolysis of FeCl3 during the ink drying process and were then directly deposited onto the SiOx/Si surface with mu CP. The nanoparticles were transferred to the areas beneath the "raised" portions of the stamp at low ink concentration but populated at the areas beneath the "recessed" portions of the stamp at high ink concentration. The hydrophobic property of the stamp surface cooperated with the gravity of the particles in bringing on such an exchange of recession and repousse. The density and size of the formed nanoparticles could be tuned by varying the ink concentration. The patterned Fe2O3 center dot xH(2)O nanoparticles were used as the catalysts for the growth of single-walled carbon nanotubes (SWCNTs) by CVD. By skillfully patterning the inks of different concentrations on the same SiOx/Si wafer, we studied the effect of the ink concentration on the growth of SWCNTs. It is also shown that this simple method could be extended to the fabrication of other metal-containing nanoparticles.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000239758300026&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Physical; Materials Science, Multidisciplinary; SCI(E); EI; 33; ARTICLE; 17; 4109-4114; 18
