<P>The hybrid structure of nanoparticle-decorated nanowires (NP@NW) combines the merits of large specific surface areas for NPs and anisotropic properties for NWs and is a desirable structure for applications including batteries, dye-sensitized solar cells, photoelectrochemical water splitting, and catalysis. Here, we report a novel <I>sol-flame</I> method to synthesize the NP@NW hybrid structure with two unique characteristics: (1) large loading of NPs per NW with the morphology of NP chains fanning radially from the NW core and (2) intimate contact between NPs and NWs. Both features are advantageous for the above applications that involve both surface reactions and charge transport processes. Moreover, the sol-flame method is simple and general, with which we have successfully decorated various NWs with binary/ternary metal oxide and even noble metal NPs. The unique aspects of the sol-flame method arise from the ultrafast heating rate and the high temperature of flame, which enables rapid solvent evaporation and combustion, and the combustion gaseous products blow out NPs as they nucleate, forming the NP chains around NWs.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2013/nalefd.2013.13.issue-3/nl300060b/production/images/medium/nl-2012-00060b_0002.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl300060b'>ACS Electronic Supporting Info</A></P>

A New Segmentation-based Animation Storage Format On Mobile Platform
Lin Feng,Ziqiang Diao,Yu Cai,Yunzhe Sun 한국멀티미디어학회 2006 한국멀티미디어학회 국제학술대회 Vol.2006 No.-
Handheld computers such as mobile phone are becoming new platform for gaming. However, the limited memory is the main bottleneck that affects the game development. A new segmentation-based animation storage format is proposed to partly solve such problem. The key unit is extracted from segmented image and then can be reused in different key frames so that the size of the animation file can be greatly reduced. Furthermore, a convenient interface for data manipulation is also proposed, which can improve efficiency during development.
