Latest Patents

One of his latest patents focuses on the synthesis of composite nanofibers for applications in lithium batteries. This invention discloses methods for fabricating one-dimensional composite nanofibers on a template membrane with a porous array through chemical or physical processes. The procedures are based on the concept of 'secondary template', where tubular first nanofibers are grown in the pores of the template membrane. Subsequently, second nanofibers are produced using the hollow first nanofibers as secondary templates. The template membrane is then removed to obtain the composite nanofibers, which demonstrate superior performance in weight energy density, current discharge efficiency, and irreversible capacity. These composite nanofibers have extensive applications, including thin-film batteries, hydrogen storage, molecular sieving, biosensors, and catalyst support.

Another significant patent involves a process for synthesizing one-dimensional nanosubstances using electron cyclotron resonance chemical vapor deposition (ECR-CVD). This invention provides a method where a membrane with channels serves as the host material for synthesis. The anodic membrane is brought into contact with a microwave-excited plasma of a precursor gas using the ECR-CVD system. This allows for the parallel alignment of nanosubstances to be synthesized in the channels of the membrane over a large area. Notably, carbon nitride nanosubstances were successfully synthesized for the first time through this process.
