We are pleased to announce Julia Rho is selected as a 2020 PMSE Future Faculty Scholar

This program aims to highlight up-and-coming postdocs and provide a platform for them to share their work at the ACS, which took place virtually this year. Julia is currently a postdoctoral researcher in the Sumerlin group working in the area of polymer chemistry. Her research spans several projects, including the study of polymer self-assembly, complex coacervates, and cyclic polymers as vitrimers. Congratulations, Julia!”

Kari Basso: Selected as the female superstar in Mass Spec

This is a group within the American Society for Mass Spectrometry that brings together women in the field of mass spec. They hold virtual workshops with people around the world focused on supporting and mentoring women in science. They hold a virtual happy hour every two weeks that includes a speaker, often female CEO’s, or speakers on work life balance issues and then we have a break out session to network. Every month they spotlight one female super star in mass spec, this month the woman chosen is our own Dr. Kari Basso. When asked, Dr. Basso described being both shocked and honored to have been chosen.

Coray Colina Receives Fulbright U.S. Scholar Award to Mexico for a Research/Teaching Appointment

The U.S. Department of State and the J. William Fulbright Foreign Scholarship Board are pleased to announce that Coray Colina of University of Florida has received a Fulbright U.S. Scholar Program award to Mexico. Colina will research/lecture at Universidad Nacional Autonoma de Mexico as part of a project to perform research on Molecular Chimeras for Opioid Receptor Modulators.

As a Fulbright Scholar, Colina will share knowledge and foster meaningful connections across communities in the United States and Mexico. Fulbrighters engage in cutting-edge research and expand their professional networks, often continuing research collaborations started abroad and laying the groundwork for forging future partnerships between institutions.

Wei group published in Energy & Environmental Science

A research paper from the Wei group has been published in Energy & Environmental Science–the top leading journal in the energy field with a 2018 impact factor of 33.250 and five-year impact factor of 32.826. The article titled “Modulating Multi-Hole Reaction Pathways for Photoelectrochemical Water Oxidation on Gold Nanocatalysts” reports a discovery that catechol molecules on Au/TiO2 heterostructures are able to directly trap and stabilize visible-light-generated hot holes on Au under steady-state reaction conditions (t ~ms–s). Those long-lived hot holes are further found to create a new reaction pathway in which the catechol-trapped holes cooperate with the newly generated holes on Au. The new mechanism boosted photoelectrochemical water oxidation on Au by one order of magnitude. Our study provides a molecular level understanding of the role of photo-generated hot holes in facilitating water oxidation, illustrating a strategy to assemble metal nanoparticles, semiconductors, and molecules to effectively separate charge carriers and harvest hot holes for driving photochemical reactions.

The research was supported by the National Science Foundation, UF Graduate School Fellowship, Department of Energy Science Graduate Student award, Ann Stasch Summer Fellowship, Vala Research Excellence Award, and College of Liberal Art and Science (CLAS) Dissertation Fellowship funded by the Charles Vincent and Heidi Cole McLaughlin Endowment.

Wei group published in JACS

A research paper from the Wei group has been published in JACS. The article titled “Cooperation of Hot Holes and Surface Adsorbates in Plasmon-Driven Anisotropic Growth of Gold Nanostars” reports a discovery that plasmon-generated hot holes work with surface adsorbates collectively to control the anisotropic growth of gold (Au) nanostructures. Specifically, it is found that hot holes stabilized by surface-adsorbed iodide enable the site-selective oxidative etching of Au0, which leads to non-uniform growths along different lateral directions to form six-pointed Au nanostars. Our studies establish a molecular-level understanding of the mechanism behind the plasmon-driven synthesis of Au nanostars and illustrate the importance of cooperation between charge carriers and surface adsorbates in regulating the morphology evolution of plasmonic nanostructures.

The research was supported by the National Science Foundation, UF Graduate School Fellowship, and Department of Energy Science Graduate Student award.

Christopher Brewer Receives UF Graduate Student Mentoring Award

Christopher Brewer has been honored with the UF Graduate Student Mentoring Award. This award is presented by the UF Graduate School and all graduate students at UF are eligible. Brewer is a fourth year graduate student in the McElwee-White lab. During his time here he has mentored two undergraduate students (Olivia Hawkins and Nicholas Sheehan) and two graduate students (Hanwen Liu and Courtney Sparrow). To Chris, mentoring others is a very rewarding part of his graduate career here.

New Faculty Hire: Alix Rexford – Biochemistry Lecturer

Dr. Rexford received her bachelor’s degree in Biochemistry from the College of Charleston. She earned her PhD in Biochemistry at Florida State University studying protein-protein interactions involved with the activation of the glycolytic enzyme glucokinase under the guidance of Dr. Brian Miller. Since 2016 she has taught chemistry and biochemistry at Florida State University. Dr. Rexford’s goal is to facilitate critical thinking in her classroom through application-based problem solving. She is excited to bring her skills to the University of Florida Department of Chemistry.
