Before geoengineering, some fundamental chemistry
Research led by Joseph S. Francisco of the School of Arts & Sciences examines the chemistry of a proposal to curb climate change’s effects—creating a sunshade in the upper atmosphere made of sulfuric acid—and finds that there’s more work to do to successfully pull off such a feat.
Improved fluorescent amino acids for cellular imaging
New research describes how to insert synthetic fluorescent amino acids into proteins in living cells, with implications for the study of neurological diseases.
Versatile ‘chemoproteomic probes’ for activity-based protein profiling
A new study uses organohydrazine probes to map chemical reactivty across the proteome, allowing for a diverse classes of proteins and biological pathways to be studied.
Identifying an elusive molecule key to combustion chemistry
Researchers made the most direct observation of a key intermediate formed during the breakdown of hydrocarbons during combustion and in the atmosphere, results that could help in the future design of fuels that burn more efficiently.
Through the thin-film glass, researchers spot a new liquid phase
A new study on thin films of glass shows how they can be fabricated to be denser and more stable, providing a framework for new applications and devices through better design.
New grant aims to broaden participation in cutting-edge materials research
As one of eight teams to be awarded National Science Foundation funding, a partnership between Penn and the University of Puerto Rico will continue its long-running collaboration focused on innovative research and STEM career pathway support.
The alternative fuel life of everyday items
Researchers in the Goldberg Group, including Karen Goldberg, Vagelos Professor in Energy Research, and Drew Newman, doctoral candidate in chemistry, focus on alternative fuel sources for items that are part of everyday life.
