Graphene-based Materials for Applications in Heterogeneous Catalysis, Water Treatment and Solar Water Desalination

This talk will address the development of three classes of graphene-based materials as (1) support for metal nanoparticle catalysts in heterogeneous catalysis, (2) sorbent materials for the removal of heavy metal ions from polluted water, and (3) photothermal energy converter materials for efficient solar water desalination.

Chemistry and Biology of Nucleic Acid- and Nucleotide-Binding Proteins

The functions of nucleotides and nucleic acids involve their interactions with cellular proteins.  In this presentation, I will discuss about our recent efforts toward the development and applications of quantitative proteomic methods for unbiased, proteome-wide discovery of proteins that can recognize unique secondary structures of DNA. I will also discuss our recent development of targeted quantitative proteomic methods for interrogating ATP- and GTP-binding proteins at the entire proteome scale.

New Chemical Probe Technologies: Applications to Imaging, Target Identification and Drug Discovery

Hydrolases are enzymes that often play important roles in many common human diseases such as cancer, asthma, arthritis, atherosclerosis and infection by pathogens. Therefore tools that can be used to dynamically monitor their activity can be used as diagnostic agents, as imaging contrast agents and for the identification of novel classes of drugs. In the first part of this presentation, I will describe our efforts to design and synthesize small molecule probes that produce a fluorescent signal upon binding to tumor associated protease targets.
