Sheng Dai

Sheng Dai is a renowned inventor and patent holder based in Knoxville, TN, with an impressive 62 patents to his name. Dai's latest patents have been widely recognized for their potential to revolutionize various fields of science and technology.

One of Dai's latest innovations includes the development of amidoxime-functionalized materials that extract metal ions from liquid solutions. The production of this material involves providing a precursor material that has nitrile groups appended to its surface. Dai's method then involves reacting these nitrile groups with hydroxylamine or a derivative thereof in the presence of a polar aprotic solvent at a temperature of 60-80°C. This method converts at least a portion of the nitrile groups to amidoxime and imide dioxime groups. Dai's functionalized material has a higher uranium absorption capacity than a functionalized material produced under the same conditions except that the nitrile groups are reacted with hydroxylamine in only a protic solvent. Dai's patent also includes methods for using this functionalized material to extract metal ions from metal-containing solutions.

In addition, Dai has also developed nitrogen-sulfur-carbon nanocomposites with their application as cathode materials in lithium-sulfur batteries. These electron-conducting porous compositions comprise an organic polymer matrix doped with nitrogen atoms and having elemental sulfur dispersed therein. Dai's patent also includes composites of S/N-doped electron-conducting porous aromatic framework compositions and S/N-doped mesoporous carbon composition. A binder and optionally conductive carbon can be added to these composites, which can be incorporated into cathodes for a lithium-sulfur battery.

Dai has worked for various companies, including UT-Battelle, Inc. and UNIVERSITY OF TENNESSEE RESEARCH FOUNDATION. He has had the pleasure of working alongside talented individuals such as Xiao-Guang Sun and Huimin Luo.

In conclusion, Sheng Dai's patents highlight his dedication to innovation and cutting-edge research. His work has the potential to make significant contributions to various areas of science and technology, and we can't wait to see what he comes up with next.
