2019 IUPAC FOR AFRICA: POSTGRADUATE SUMMER SCHOOL ON GREEN CHEMISTRY
Dr. Isai T. Urasa was an invited speaker at the “2019 IUPAC for Africa: Postgraduate Summer School on Green Chemistry” that occurred at the University of Dar es Salaam, Dar es Salaam, Tanzania, May 12-19, 2019. Organized and managed by the IUPAC Inter-divisional Committee on Green Chemistry for Sustainable Development (ICGCSD), this was one of many events that have been organized in celebration of the IUPAC Centenary and the 150th anniversary of the creation of the Periodic Table. The six-day event was the first to be held on the Continent of Africa.
The Summer School was hosted by the University of Dar es Salaam (UDSM), University of Dodoma (UDOM) and the Tanzania Bureau of Standards (TBS) in collaboration with the Tanzania Chemical Society (TCS). Both UDSM and UDOM are among highly ranked Universities in Africa offering a wide range of academic disciplines at both undergraduate and postgraduate levels. The goal of the Summer School was to provide a platform for the participants to discuss the concepts, practice, and applications of green/sustainable chemistry. It is expected that events like this will have a catalytic effect on encouraging young African scientists, engineers and others, to create new solutions for a more sustainable development agenda for the Continent. Participants of the Summer School (mostly early career chemistry professionals and graduate students) represented a broad range of African Countries from Morocco to South Africa, Europe, the U.S., and China. The event included 12 lectures given by invited speakers, and 55 poster presentations given by early career professionals and graduate students, covering a broad range of research topics centered on the Twelve Principles of Green Chemistry & Sustainability. Many of the presentations had a strong emphasis on Catalysis. Also in attendance were IUPAC President Qifeng Zhou and Vice President Chris Brett (IUPAC President elect).
ANNUAL DEPARTMENTAL DINNER
The annual Department of Chemistry and Biochemistry dinner was held on December 4, 2019 in the Student Center Cyber Lounge. Senior Stephanie Chigbu opened with a greeting and blessing, followed by a delicious meal prepared by staff and faculty. Everyone enjoyed reflections offered by a representative of each year group and Dr. Asojo presented certificates to recognize outstanding academic performances by students.
Two returning alumni were in attendance, Janay Little and Kennedy Goldsborough. They are both pursuing advanced degrees at VCU in Richmond. The presenter for the evening was Janay Little who spoke on her activities at VCU including her research on type IV pili biogenesis in E. coli.
Dr. Stefan France from Georgia Institute of Technology had planned to give a seminar on “Acceptor-Acceptor Diazo Compounds as Building Blocks for Intermolecular C-H Functionalization” on Thursday, March 19, 2020 but unfortunately the seminar was postponed due to the corona virus
The commonwealth of VA approved the Masters in Chemistry Teaching degree in Fall 2019.
The Department welcomed Mr. Zachary Messegee as the Chemical Instrument Technician. Mr. Messegee provided support for teaching and research instrumentation and the water quality lab. He worked with Dr. Isai Urasa, monitoring local estuaries and wetlands in the Hampton, VA area and performing measurements for trace heavy metals, nitrate/nitrite and phosphates. Mr. Messegee was accepted to graduate school recently and we wish him well in his future studies.
We also welcomed Dr. Renata Baroni, a post-doc working with Dr. Asojo, who helped train students in biochemistry and biotechnology techniques. Dr. Baroni completed her nine-month international Post-doctoral fellowship in March 2020. She worked under the mentorship of Dr. Oluwatoyin Asojo and was funded by São Paulo State Research Foundation (FAPESP).
