Research Probing Atmospheric Chemistry above Alaska Published

Dr. Tim Starn and collaborators investigated the role of BrO in ozone depletion in this paper published in Atmospheric Chemistry and Physics. Reactive halogen chemistry in the springtime Arctic causes ozone depletion events and alters the rate of pollution processing. There are still many uncertainties regarding this chemistry, including the multiphase recycling of halogens and how sea ice impacts the source strength of reactive bromine. In this study, observations from the CHACHA (CHemistry in the Arctic: Clouds, Halogens, and Aerosols) field campaign based out of Utqiaġvik, Alaska, from mid-February to mid-April of 2022 provided information on the vertical distribution of bromine monoxide (BrO), which is a tracer for reactive bromine chemistry.

WCU Award Dreyfus Lectureship

Congratulations to Drs. Danielle Chirdon and Kimberly Mullane on being awarded the 2023 Jean Dreyfus Lectureship for Undergraduate Institutions!

The Jean Dreyfus Lectureship awards provide a grant to bring Professor Suzanne Bart of Purdue University to give  two lectures in the chemical sciences. One of the lectures should be accessible and promoted to a wide audience that includes the general public. The second lecture will be more technical. A portion of the award is to support two undergraduates in summer research. You can register for the poster session and technical talk on Saturday, April 20th here.

Louis Stokes Alliance for Minority Participation Leadership and Academic Enhancement Program

The NSF-funded, Louis Stokes Alliance for Minority Participation Leadership and Academic Enhancement Program, named in honor of former congressman Louis Stokes, is to support historically underrepresented students pursuing a major in science, technology, engineering, and/or mathematics. Keystone LSAMP Scholars will conduct research, participate in academic and professional development (including summer camps and field trips), collaborate with an Alliance-wide community of LSAMP Scholars, and receive financial stipends and travel support. If you have any questions, please contact: Professor Azam. Please go to this website for more details and to access the application link.

Collaboration with Stanford Reveals Unexpected Reactivity of Silica

Considering the widespread use of mesoporous silica particles in our daily life as well as in medicine, the significant extent of oxidation facilitated by such previously considered chemically inert materials deserves much attention. Oxidation by such particles was studied in detail using nanoelectrospray ionization mass spectrometry. Data showed that more oxidation was measured when molecules have easier access to particle surfaces. The unexpected reactivity found for L-cysteine, glutathione, and D-penicillamine were reported in the Proceedings of the National Academy of Sciences by Dr. Yangjie Li and Professor Richard N. Zare, both in the Chemistry Department at Stanford University, working together with WCU's Kurt W. Kolasinski. More about this work is available in this news article published in Chemical and Engineering News.

Study on Muscle Membrane Repair Pathways Sheds Light on Origins of Muscular Dystrophy

Dr. Tom Kwiatkowski is part of an international team that has published the results of a study to assess the role of murine Dysf exon 40a in membrane repair and development of dysferlinopathy in mice. Their paper titled "Minimal expression of dysferlin prevents development of dysferlinopathy in dysferlin exon 40a knockout mice" has been published in Acta Neuropathologica Communications.

Dr. Constantinos Pistos invited talk at Chromatography Forum of Delaware Valley

Dr. Pistos gave a talk at the Chromatography Forum of Delaware Valley's (CFDV) 2023 annual Symposium in Claymont, DE on April 20th. His speech was entitled “Green Analytical Toxicology: What is the future in Forensic Toxicology?”.

The Chromatography Forum is an active and engaging organization and fosters a spirit of fraternity among those engaged in chromatography. It promotes practical use and theoretical knowledge for educational benefit and professional development of its members.

Winterthur Conservation Scientists Visit Chemistry Department

We had some visitors from the Winterthur Museum Scientific Research and Analysis Laboratory (SRAL) in the Chemistry Department. Conservation Scientist Catherine Matsen, along with Winterthur/University of Delaware Program in Art Conservation (WUDPAC) graduate student Tammy Hong visited the research lab of Dr. Zachary Voras to investigate the composition of Chinese export miniature paintings.

Dr. Kimberly Mullane spoke at Philadelphia Inorganic Colloquium

Dr. Mullane delivered an Invited talk at the Philadelphia Inorganic Colloquium to be held on 22 April at the College of New Jersey. Her talk is titled "Early (Zr, Hf) and Late (Cu) Transition Metals in Energy Applications." If you would like to attend, registration is now open. Free for all attendees.

The Philadelphia Inorganic Colloquium is a forum for chemists in the Delaware Valley. Each Colloquium features lectures from local researchers and a poster session for undergraduate, graduate and postdoctoral scholars. Learn more.

Professor Kurt Kolasinski Named a Fellow of the American Association for the Advancement of Science

Kurt Kolasinski, WCU professor of chemistry, has been named a Fellow of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society and publisher of the Science family of journals. This honor recognizes his lifetime work, specifically “his outstanding contributions to surface science and his efforts to educate others about this field.”

NSF Grant for a new Scanning Electron Microscope Awarded

The National Science Foundation has funded our proposal for the purchase of a field emission scanning electron microscope (FE-SEM). The $391,730 grant will be used to purchase an Apreo 2 from ThermoFisher FEI to replace our existing SEM. This instrument, which can image objects with 1 nm resolution and quantify elemental composition, is used in advanced undergraduate laboratory courses as well as research. It will be housed in the Center for Microanalysis and Imaging Research and Training (CMIRT), which is a facility supported by the College of the Sciences and Mathematics. Principle Investigator Dr. Kurt Kolasinski (Chemistry) was joined by Dr. LeeAnn Srogi (Earth & Space Sciences), Dr. Howell Bosbyshell (Earth & Space Sciences), Dr. Brandon Mitchell (Physics) and Dr. John Pisciotta (Biology) in the proposal. These researchers will use the new instrument to probe the structure of nanomaterials and semiconductors, to investigate the interactions of nanoparticles with the environment, and to study microtextures and chemical composition of mineral grains.
