About 494 presentations (287 oral, 207 posters) at this conference covered the following 13 areas: Adsorption and gas storage, Biological and medical application, Carbon nanomaterials, Chars/cokes and industrial applications, Electronic/Electrochemical properties and applications, Flame formed carbons, Materials characterization/techniques, Membranes/pyrocarbons and diamond films, Novel forms and chemically modified carbons, Porous carbons/activations, Precursor chemistry/carbonization and graphitization, Reactivity/catalysis and surface science, Structural carbons/fibers and composites. Carbon nanomaterials and nanostructure were highlighted at this conference, 12 of all 48 oral sessions and 112 of all 494 papers being on this topic. A pre-(conference) workshop, A Colloquium on Carbon Nanoforms, and three of the four plenary lectures reported the latest (development) and showed us the current trends in research on Carbon nanomaterials. At this conference, the idea was emphasized that the "nano" concept now not only represents some kinds of materials and structure, but also, much more important, brings us a new insight to carbon materials, novel or conventional. Carbon scientists firmly believe that they are trying to create the "golden age" of Carbon materials.Blood coagulation resistance of nonwoven single-walled carbon nanotubes and its implications for implantable prosthesesMENG Jie^1,SONG Li^2,KONG Hua^1,WANG Chao-ying^2,GUO Xiao-tian^1,XU Hai-yan^1,XIE Si-shen^2(1.

The adsorption behaviors of fibrinogen, albumin and fresh plasma on SWNT membrane were investigated by scanning electron microscopy (SEM) and energy dispersive X-ray analysis. The platelet adhesion and activation induced by the SWNT membrane were evaluated through SEM observations and fluorescent labeled flow cytometric analysis. Results indicated that the SWNT membrane showed a clear adsorption preference of fibrinogen over albumin. However, there was no appreciable platelet adhesion and activation occurred consequently on a SWNT membrane surface pre-absorbed with fresh plasma, and the percentage of activated platelets caused by a SWNT membrane in a platelet-rich-plasma was about 5?%. The conclusion is that the SWNT membrane has unique platelet inertness in blood environments and this anticoagulant effect permits potential use in artificial organs, prostheses and tissue engineering in the cardiac-vascular systems.展开更多
