Guess who was the fastest driver?

Hello, my name is Jeffrey Walters. I am a rising junior at Virginia State University. I am a chemistry major with a concentration in biochemistry. After graduating I plan on either going into the workplace or joining a M.D program where I will pursue my dream of becoming a doctor.

I am working in Dr. Zhang’s lab during my time here at UC. His lab focuses on exploring nanoscience which offers one of the most exciting opportunities for innovation in technology. Specifically, my project is focused on silica nanoparticles (mSiO2) which can act as a carrier to deliver something easily. For example, a drug. These porous nanoparticles have many pores. After creating them from conducting a synthesis they are loading with toluidine blue (TBO), a photosensitizer, and coated with a dopamine shell. The TBO molecule is water soluble dye molecule that will help me observe the process. I am working and analyzing the best way these mSiO2 particles can be loaded by using various techniques and methods.

Daniel Leong is a rising Sophomore at the University of Cambridge. He is studying Natural Sciences and intends to specialize in Chemistry. He grew up in Malaysia but is now living in Cincinnati, OH. This summer, Daniel is conducting research at Dr Yujie Sun’s lab under the

guidance of graduate student Guanqun Han. He is investigating the novel application of two-photon absorption (TPA) in photocatalysts. TPA occurs when two low-energy infrared-red (IR) photons are absorbed to emit an energetic ultraviolet (UV) photon capable of initiating chemical reactions. In comparison to UV light, IR radiation is only weakly absorbed by the solvent, has greater penetration through media, and can be abundantly harvested from the Sun. His work on this topic will help elucidate this physical process and reap benefits from using IR light in photocatalysis. He is responsible for the synthesis of novel photocatalysts with large TPA cross sections, modifying substituents to tune the photocatalyst for specific reactions.
