Page 3 • Lehigh University We were delighted to welcome Fatema Amin to the research group this year. She is using selfassembled monolayers to tune the surface chemistry of substrates for the next phase of our study of the key experimental parameters that affect roll-off angles. Kiran Khadka’s paper in that area appeared in Langmuir early in 2022. Zahed Ghelichkhah continues to be a powerhouse in the research lab, publishing his second paper in the Electrochimica Acta and submitting his third manuscript. We also bid farewell to Tarannuma Ferdous Manny, who has joined her new spouse at Florida State University – we wish the new couple well! “Anion-Catalyzed Active Dissolution Model for the Electrochemical Adsorption of Bisulfate, Sulfate, and Oxygen on Gold in H2SO4 Solution,” Z. Ghelichkhah, R. Srinivasan, D.D. Macdonald, G.S Ferguson, Electrochimica Acta 2023, 439, 141515; https://doi.org/10.1016/j.electacta.2022.141515. “Does the Roll-off Angle Depend on Work of Adhesion?” K. Khadka and G.S. Ferguson, Langmuir 2022, 38, 4820–4825; https://doi.org/10.1021/acs.langmuir.1c03425. The Fisher lab has been hard at work investigating the molecular basis by which bacteria respond to changes in their environments. We received funding to specifically support our research on bacterial copper acquisition through a LEAPS-MPS grant from the NSF. During the past year, we welcomed several new lab members: Chemistry graduate student Jess Mickno and undergraduates Dia Zheng (Biochemistry, ’23), Emerald Kan (Biochemistry, ’23), David Han (Biochemistry, ’23), and Mu Hu (Biology, ’23). We also bid farewell to the lab’s first undergraduate student, Jing Guo, who graduated with Honors in Biochemistry last Spring and recently started a position as a research technician at the Dana Farber Cancer Institute at Harvard Medical School. Before she graduated, Jing and Oriana wrote a review article about cupredoxin domains, a protein fold that is used by many copper-binding proteins for a wide range of biological functions that was recently published in The Journal of Biological Inorganic Chemistry. Members of the group have also shared our research at a number of venues, both virtual and in-person. Dia, David, and Emerald all participated in the summer STEM-SI program and gave poster presentations about their research. Dia also gave a virtual talk at the ISCC this past April. During the past year, Oriana has also given several talks and presentations, including a poster presentation at the ASBMB annual meeting in Philadelphia, a seminar at Moravian University, a talk at the ACS Mid-Atlantic Region Meeting in New Jersey, and a talk at the 12th International Copper Meeting in Italy. The Fredin Group kept busy this year working on large scale computational problems at the intersection of photochemistry and material disorder. In particular, projects looking at inherent disorder (packing defects or molecular vibration) and induced disorder (dopants) have allowed the group to solve important problems in light-driven faceted and reconstructed nanoparticle catalysis, vibrational effects on conduction in organic materials, and the photoexicited state dynamics of organic molecules. Two undergraduates and one Masters student graduated from the group and are moving on to dental school, graduate school in chemistry, and a job in chemical industry. Graduate student, Zach Knepp passed his general exam and post-doc Dr. Anum Shahid Malik joined the group in January. The current group consists of three graduate students, one post-doc, and seven undergraduates. The 2nd year of PURE (Photochemistry Undergraduate Research Experience), which combines computation and
