A team of researchers studied water under extreme conditions, discovering its structure transforms from ordered to disordered at supercritical temperatures. This knowledge provides an improved estimate of water's behavior during geochemical and geological processes.
A team of scientists discovered that cloud seeds can pick up molecules even when they don't collide directly with the clusters. The finding has significant implications for understanding atmospheric chemistry processes such as ozone depletion.
Scientists discover water's conductivity increases at extremely low temperatures, contradicting expectations for an ordinary liquid. This phenomenon supports the idea of a 'liquid-liquid' phase transition in water.
Scientists have observed water's retardation of dynamism in biological enzyme substrate compounds, which acts like an 'adhesive' to control metabolic processes. This finding has implications for future drug design and development of medicines.
A newly synthesized polymer, fitted with molecular pincers, effectively captures nicotine molecules and its analogues. The polymer can be used for fabrication of sensitive and selective chemical sensors to determine nicotine in solutions, as well as for slow, controlled release of nicotine for therapeutic purposes.
Frank Millero, a leading expert in marine geochemistry, has been awarded the prestigious V.M. Goldschmidt Award for his major achievements in the field. His research focuses on understanding biogeochemical processes and the global carbon dioxide cycle in the world's oceans.
Phillip A. Sharp has been awarded the 2010 Herbert Tabor Lectureship for his groundbreaking research on small RNAs, RNA interference, and its potential to revolutionize biology and generate new therapeutics. Sharp's work builds on his landmark discovery of RNA splicing in 1977, which earned him a Nobel Prize in Physiology or Medicine.
Udayan Mohanty, a physical chemist at Boston College, received a 2009 Guggenheim Fellowship to study rare chemical reactions using new computational models. He aims to discover unknown reaction pathways, particularly those surrounding DNA and RNA behavior.
Gabor A. Somorjai has been recognized with the 2008 Priestley Medal for his pioneering work in surface science and catalysis, driving significant advancements in materials science and nanoscience. His research has led to thousands of publications over 40 years.
Soft Matter will separate from its host journal in January 2007, becoming an independent publication with a focus on interdisciplinary research. The move is expected to have far-reaching effects for the soft matter community.
COACh founder and chair Geri Richmond will use $10,000 grant to expand mentorship programs to Latin America, aiming to improve hiring and promotion of women in academic chemistry departments. Richmond's organization has seen success with its workshops and leadership forums, increasing women's participation and reducing workplace stress.
Miller develops accurate chemical models by simulating traffic flow and manipulating equations to predict real-world outcomes. He aims to use these models to save laboratory time, money, and point to new avenues of research.
Christensen studies carotenoids' role in photosynthesis, a process by which plants turn light into chemical energy. His work draws students to the basics of physical chemistry, influencing his teaching at Bowdoin College.
Geraldine Richmond, a renowned Oregon chemist and educator, has been recognized for her efforts to foster diversity in the chemical workplace. She founded the Committee on the Advancement of Women in Chemistry (COACh) to support women chemists and promote gender equality.
Dai and his team have developed a system to control the synthesis of carbon nanotubes, enabling their use in sensing technologies. One type of nanotube structure shows promise as a sensor for detecting nitrogen dioxide, a common pollutant in vehicle exhaust.
Giacinto Scoles receives Peter Debye Award in Physical Chemistry for inventing new methods of creating controlled molecular beams, allowing study of chemical reactions in unprecedented detail. These techniques also contribute to the development of better semiconductors with improved performance.
Researchers at the University of Pennsylvania found that adding a 'fuzz' of chemical chains to colloidal molecules can lead to the formation of predictable arrays of lattices. This entropy-driven phenomenon offers promise for designing new materials rationally rather than through trial and error.
Chemist William R. Dolbier receives American Chemical Society Award for Creative Work in Fluorine Chemistry for innovative studies of fluorine, which strengthens bonds and makes products like Teflon resistant to high temperatures.
Dr. Mario Molina, Nobel laureate and environmental science professor, will address his experiences as a minority in the sciences at the American Chemical Society meeting. He will also discuss his work on ozone depletion and atmospheric chemistry.
Koehler's project focuses on the adsorption of trace atmospheric gases on soot under simulated conditions. Her research aims to understand how soot derived from jet fuel affects the chemical balance of the atmosphere, with potential implications for sulfur dioxide conversion to sulfuric acid.
Thomas Holme, a chemistry professor and TV personality, receives the Helen M. Free Award for Public Outreach from the American Chemical Society for his efforts to increase public awareness of chemistry through TV appearances and local activities. His segments air on WTMJ-TV, reaching an audience of over 200,000 viewers since 1995.
