标题:Synthesis of uniform diamond nanoparticles
发明人：YAN HAO; LYU TENGTENG
权利人:UNIV NORTH TEXAS
摘要:The synthesis of sub-five-nanometer nanodiamonds with high uniformity and purity. Inspired by the formation of natural diamond, iron carbide nanoparticles embedded in iron oxide matrices as the carbon source were used. High-pressure-high-temperature treatment of the precursor yields nanodiamonds with tunable diameters down to 2.13 nm and 0.22-nm standard deviation. The disclosed synthesis procedures also include a method for forming fluorescent nanodiamonds.

权利人:THE UNIV OF TULSA
摘要:Disclosed is a process for producing graphene from solid hydrocarbons including biomass and coal. The disclosed method does not require the presence of hydrogen and does not operate under a vacuum. The method begins by converting biomass to a graphene precursor while coal is used as is. Subsequently, the method grinds the graphene precursor to provide a desired particle size. The particles of graphene precursor (biocoal or coal) are converted to graphene by catalytic conversion on metallic foil under atmospheric conditions and in the absence of hydrogen.

标 题:Bottom-Up, Scalable Synthesis Of Oxide-Based Sub-Nano And Nanofilaments And Nanofilament-Based Two-Dimensional Flakes And Mesoporous Powders
发明人：BARSOUM MICHEL W; BADR HUSSEIN OSAMA
权利人:UNIV DREXEL
摘要:Provided are methods to convert—through a bottom-up approach—binary and ternary titanium carbides, nitrides, borides, phosphides, aluminides, and silicides into lepidocrocitic nanofilaments that in some cases self-assemble into 2D flakes by immersing them in a quaternary ammonium solution at moderate temperatures. The resulting flakes can comprise nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances.

摘要:Provided are methods to convert - through a bottom-up approach – binary and ternary titanium carbides, nitrides, borides, phosphides, aluminides, and silicides into nanofilaments that in some cases self-assemble into 2D flakes by immersing them in a quaternary ammonium solution at moderate temperatures. The resulting flakes can be C-containing anatase-based layers that are in turn comprised of nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances. Electrodes made from these materials performed well in energy systems. The materials also reduce the viability of some cancer cells. Also provided are mesoporous materials, devices, and related methods.
