PHILADELPHIA –- Researchers have discovered the middleman in the complex chemical reaction that is essential to the atmosphere's ability to break down pollutants, especially the compounds that cause acid rain. The study improves the basic understanding of the chemical removal of acid rain and will allow scientists to better model how pollutants are removed from the atmosphere and to predict potential environmental conditions.

PHILADELPHIA –- The Penn Cultural Heritage Center, dedicated to expanding scholarly and public awareness, discussion and debate about complex issues surrounding the world’s endangered cultural heritage, has been established at the University of Pennsylvania Museum of Archaeology and Anthropology in Philadelphia.
PHILADELPHIA –- Physicists at the University of Pennsylvania have characterized an aspect of graphene film behavior by measuring the way it conducts electricity on a substrate. This milestone advances the potential application of graphene, the ultra-thin, single-atom thick carbon sheets that conduct electricity faster and more efficiently than silicon, the current material of choice for transistor fabrication.
University of Pennsylvania Researchers Demonstrate a Flexible, One-Step Assembly of Nanoscale Structures
PHILADELPHIA –- Scientists at the University of Pennsylvania have created a one-step, repeatable method for the production of functional nanoscale patterns or motifs with adjustable features, size and shape using a single master “plate.”
