Topic: Quantum Dots: The Nobel Prize in Chemistry 2023
The Nobel Prize in Chemistry 2023 rewards the discovery and development of quantum dots, nanoparticles so tiny that their size determines their properties. These smallest components of nanotechnology now spread their light from televisions and LED lamps, and they guide surgeons when they remove tumor tissue, among many other applications.
Physicists had long known that in theory, size-dependent quantum effects could arise in nanoparticles. Few people believed that this knowledge would be put to practical use. However, in the early 1980s Aleksey Yekimov created nanoparticles of copper chloride in glass. Their size affected the color of the glass via quantum effects.
A few years later, Louis Brus was the first scientist to prove size-dependent quantum effects in particles floating freely in a fluid. In 1993 Moungi Bawendi revolutionized the chemical production of quantum dots, resulting in almost perfect particles. This high quality was necessary for them to be utilized in applications.
Quantum dots now illuminate computer monitors and television screens based on QLED technology. They add nuance to the light of some LED lamps, and biochemists and doctors use them to map biological tissue.
Philip W. Apruzzese (BE Chem. E., MS Technology Mgmt., CHMM) graduated from Stevens Institute of Technology, Hoboken, NJ. He was employed in the pharmaceutical industry (Squibb, Beecham, Schering-Plough) for nearly 40 years, holding manufacturing operations, project, research pilot plant startup, and environmental compliance management positions. From 2010 to 2019 he was employed part-time as a Chem Eng/Environmental, health and safety consultant, in addition to working seasonally as a Level C Official for USA Cycling racing events. Since relocating to the Seattle area he has begun volunteer work with several non-profit community cycling/Recycling resources and advocacy organizations. In 2015, he spoke on Tour de France cycling performance enhancements – Post Lance/Post Drugs. In 2019 and 2021 he presented on the Nobel Prize in Chemistry before the Lyceum Society.

Speaker: Kiran Rachamallu
Topic: The Scientist’s Role in Crafting Effective Public Policy (Annual address by an alumnus of the NYAS Junior Academy)
Increasingly, the scientific community has been called upon to utilize their expertise when making important policy decisions. This talk will highlight how scientific research is used in the context of policy making in the federal government, demonstrating how to ensure that policies are based on accurate information that reflects the latest scientific advancement. Using real world examples such as climate change, antibiotic resistance, and Covid-19, this talk will go through some strategies on how scientists can ensure their voices are heard as well as best practices for translating cutting-edge scientific research into real world policy change.
Kiran Rachamallu is a Research Assistant at the Center on Budget and Policy Priorities (https://www.cbpp.org). He has previously worked for the Department of Health and Human Services and the American Institutes for Research. Kiran is skilled in conducting both basic science and social science research and specializes in translating the latest scientific research into recommendations for policymakers. Throughout high school, he was a member of the Junior Academy of the New York Academy of Sciences and participated in several challenges. Kiran graduated summa cum laude from the College of William and Mary with a Bachelors in Public Policy and Biology.
The Lyceum Society is a collegial venue promoting fellowship, education, and discussion among retired members of NYAS.
