Q. Jason Niu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: This invention is cross-linked, polymerized hydrocarbon particles which composition is characterized in that the particles have an average diameter of less than 30 nm, the particles exhibit a volume swell factor of no greater than 3.0; the composition is essentially free of metal ions; the particles have a polydispersity (polystyrene relative Mw/Mn) of less than 3.0, and the particles are characterized by a Mark-Houwink plot having a slope with an absolute value of less than 0.4 for the peak molecular weight range. The invention is also a method of making nanoparticles having a weight average diameter less than 30 nm by emulsion polymerization in the substantial absence of ionic components. Finally, the invention is a method of using such particles as thermally degradable components in making porous films.
