"Nanoscience, Biological Imaging, and Renewable Energy" by Hongjie Dai

-

Location: 107 Carey Auditorium, Hesburgh Library

Dai2 300x300
Abstract

This talk presents Prof. Hongjie Dai’s recent work in carbon-based nanosciences. He will first briefly review his group’s earlier work of carbon-based nanomaterials, and then focus on fluorescence biological imaging in the newly coined 1000-1700 nm NIR-II window to benefit from suppressed light scattering at long wavelengths. Prof. Dai will show in vivo NIR-II imaging with millimeter tissue depth, single-cell spatial resolution, and real-time temporal resolution using a wide range of nano-scale fluorescent/luminescent nanoprobes emitting > 1000 nm including carbon nanotubes, quantum dots, rare-earth down-conversion nanoparticles, and donor-acceptor organic molecules.

In the second part of the talk, he will briefly present his group’s work on the rechargeable Al battery, Na/Cl2, and Li/Cl2 batteries based on novel carbon materials.

Biography

Hongjie Dai is the Jackson-Wood Professor of Chemistry at Stanford University. He has made fundamental contributions to nanosciences especially to novel carbon-based nanomaterials including carbon nanotubes and graphene nanoribbons. He pioneered nano-carbon biological and nanomedicine applications including imaging in the NIR-II/SWIR window. In the renewable energy area, he invented new electrocatalysts, the aluminum-ion battery and Na/Cl2 and Li/Cl2 batteries.

Dai is a member of the US National Academy of Sciences, National Academy of Medicine, and a fellow of the American Academy of Arts and Sciences. Dai received the APS James McGroddy Prize for New Materials, the ACS Pure Chemistry Award, the MRS Mid-Career Researcher Award, the NIH Director’s Pioneer Award, and others.
