Dr. Priya Pradhan and Dr. Jie He Promoted

Priya PradhanJie HeOne of the highlights in academic life are promotions in academic rank that are awarded after rigorous and lengthy review of the academic achievements by the department, the Dean, the Provost, and with the help of a number of outside reviewers. The Board of Trustees then awards the promotions based on the evaluations and recommendations of all that reviewed the academic track record. With the beginning of this academic year, we have two such promotions to celebrate: Dr. Priya Pradhan was promoted from Assistant to Associate Professor in Residence and Dr. Jie He was promoted from Assistant to Associate Professor with tenure. Please join us in congratulating Priya and Jie!

Priya is teaching general and organic chemistry at the Hartford campus. She graduated in 2009 from UConn with a Ph.D., having worked in the research group of Professor Bill Bailey.

Jie established a thriving research group at Storrs after he joined our department in 2014. His broad range of research interests center on the integration polymers with inorganic materials (metal ions, clusters and nanoparticles).

Congratulations again! We are proud to have you both in our Department!

After 45 Years of Teaching, Professor Bailey Retires

BaileyAfter a 45-year successful career at UConn, Professor Bill Bailey retired at the beginning of this academic year. Alas, retiring is the wrong word: Bill merely stepped away from active teaching. He will still be found in the building (when anyone can be found in the building again). We certainly will also see continued scholarly work being published by him.

Bill’s research is in the realms of organolithium chemistry methodology, mechanisms, and conformational analyses. His dedication and creativity as an educator and mentor extraordinaire is to be celebrated.

Please join us in thanking and congratulating Bill!

Welcome to Fall 2020

A Message from the Department Head

Dear All,

Welcome to a new semester! The campus and building have come alive once again. We are welcoming new faculty and graduate students to the Department, we have awards and a retirement to celebrate, and we have a large group of students eagerly lining up for general or organic chemistry classes. Alas, this is not going to be a normal semester. Almost everything will be very different and difficult in ways that are predictable and unpredictable. Continue reading

A Tale of Two Lab Courses

A recent article in ACS Publications, from Prof. Kiet Tran, Prof. Anwar Beshir, and Prof. Abhay Vaze, demonstrates a comparison of the experiences of both organic and analytical lab faculty during the COVID-19 pandemic distance learning initiative is described here. Faculty of both lab courses experienced four shared challenges in the transition to the online format: (1) experimental implementation, (2) assessments and postlab activities, (3) technological inequalities, and (4) synchronization of student attendance.

Mercury Remains a Persistent Poison in Connecticut’s Still River

Western Connecticut is known for rolling hills, rich history, and industry, such as hat making. Once called the “Hat City of the World,” Danbury thrived. Anyone familiar with Lewis Carroll’s Mad Hatter may also be aware of the dangers of hat making, due to the industry’s use of the potent toxin mercury. Starting in the late 1700s, Danbury hat factories were a point source of pollution, dumping large quantities of mercury into the nearby Still River.

Fashions change, the use of mercury in hat making was outlawed in 1940, and now all that remains of the once-thriving hatting industry in Danbury is its history – or is it?

A group of researchers from UConn and Wesleyan University spent four years studying a stretch of the Still River, and found that the industrial waste of a century ago is still very much present in 2020.

Kayla Anatone ’12 (CAHNR), a current PhD student at Wesleyan University, was interested in the local history but also in learning if “legacy” mercury was impacting the environment and making its way into the food web. She and co-authors from the UConn Marine Sciences department – including PhD student Gunnar Hansen, Professor Robert Mason*, Assistant Research Professor Zofia Baumann and Wesleyan University Professor Barry Chernoff – recently published the findings in Chemosphere.

Passing of Jane Knox, Emerita Faculty

KnoxJane received a BA degree in chemistry from Bryn Mawr College in 1961 and a Masters in Teaching (MAT) degree from Harvard University in 1962. After teaching high school chemistry in Pearl River, NY, she attended Boston University where she obtained an MA in chemistry in 1968. Accompanying her husband to Oxford University for two years, she joined the biophysics research group of Nobel Laureate Prof. Dorothy Hodgkin and assisted in the atomic-level structural determination of insulin. Returning to the US, she worked briefly with Prof. Frederick Richards in the Department of Molecular Biophysics and Biochemistry at Yale University. In 1971, Jane began employment at the University of Connecticut as a Lecturer in Chemistry.

In our Department she supervised our undergraduate analytical chemistry laboratories, helping to write the department’s laboratory manual “Experiments in Analytical Chemistry” with an emphasis on electronics and instrumentation. She organized the Chemistry Olympiad for high school students in Connecticut and Massachusetts and later started a new course entitled “Chemistry for an Informed Electorate,” a longtime interest of hers. She served on several University policy committees, including on the College of Liberal Arts and Sciences (CLAS) Courses and Curriculum Committee. Jane was appointed an Assistant Dean in the Advisory Center of CLAS from 1992 to 1997, returning to the Chemistry Department from which she retired as Lecturer Emerita in 2003. In her retirement, Jane continued her involvement with the Connecticut Valley Section of the ACS where she championed the Chemistry Olympiad and engagement of high school teachers. She was also the driving force behind meetings of the emeritus faculty members in the Chemistry Department.

Many of you will remember Jane as an instructor dedicated to her students, holding all to a high standard. She was a true scholar — ever curious and interested in learning and exacting in all her activities. While she will be missed, her legacy of contributions to the Department and to the community will continue.

Contributions in Jane’s honor may be made to the Jorgensen JOY program through the University of Connecticut Foundation, 2390 Alumni Drive U-3206, Storrs, CT 06269. Online memories of Jane may be written at: https://www.potterfuneralhome.com/obituary/Jane-Knox.

Bird Eggshells Just Became More Colorful

Two eggs showing novel eggshell pigments: guacamole green and purplish-brown of two tinamous speciesFor well over 100 years, only two pigments have been identified in avian eggshells: rusty-brown protoporphyrin (e.g., brown chicken eggs) and blue-green biliverdin (e.g., turquois eggs of robins). However, tinamou (chicken-like forest dwellers of South America) eggshells display unusually colored eggshells, suggesting the presence of other pigments. The Brückner Group, in collaboration with the ornithologists and eggshell and bird color experts Daniel Hanley (Long Island University) and Richard Prum (Yale University), investigated this. Through extraction, derivatization, spectroscopy, chromatography, and mass spectrometry, they identified two novel eggshell pigments: yellow–brown bilirubin and red–orange uroerythrin from the guacamole-green and purplish-brown eggshells of two tinamous species. Both pigments are known porphyrin catabolites and were found in the eggshells in conjunction with biliverdin. A colour mixing model using the new pigments and biliverdin reproduced the respective eggshell colours. These discoveries expand our understanding of how eggshell colour diversity is achieved. The ability of these pigments to photo-degrade may have an adaptive value for the tinamous – this is the subject of follow-up studies for the ornithologists.

Atomwise Partnership Enables UConn Researcher to Investigate COVID-19 Drug Target

University of Connecticut professor of molecular and cell biology James Cole* is working on identifying new therapeutics for COVID-19.

Through a collaboration with Atomwise, a California-based company which uses artificial intelligence to advance small molecule drug discovery, Cole is one of the 15 researchers looking at different coronavirus protein targets for COVID-19 treatment.

Cole is focusing on the NSP15/EndoU ribonuclease enzyme the COVID-19 virus needs to replicate as well as degrade viral RNA to hide it from host cell defenses. Cole is looking for a molecule that can inhibit the enzyme and thus inhibit replication of coronaviruses.

“The virus and the host carry out this war,” Cole says. “The virus has to evade the host’s innate immunity response while the host is trying to stop the virus from replicating.”

By inhibiting this enzyme, the body’s innate immune system would prevent the virus from replicating. Continue reading
