PHILADELPHIA — Ancient pollen and charcoal preserved in deeply buried sediments in Egypt’s Nile Delta document the region’s ancient droughts and fires, including a huge drought 4,200 years ago associated with the demise of Egypt’s Old Kingdom, the era known as the pyramid-building time.
Penn Researchers and Colleagues Create a Cheaper, Cleaner, More Efficient Catalyst for Burning Methane
PHILADELPHIA — As the world’s accessible oil reserves dwindle, natural gas has become an increasing important energy source. The primary component of natural gas is methane, which has the advantage of releasing less carbon dioxide when it’s burned than do many other hydrocarbon fuels. But because of the very stable structure of the methane molecule, it can be difficult to access the energy stored within.
PHILADELPHIA – Charles L. Kane of the University of Pennsylvania is among three who have been awarded the 2012 Dirac Medal and Prize by the Abdus Salam International Centre for Theoretical Physics.
PHILADELPHIA — Many recent advances in microtechnology and nanotechnology depend on microscopic spherical particles self-assembling into large-scale aggregates to form a relatively limited range of crystalline structures. Directed assembly is a new branch of this field, where scientists figure out how to make particles assemble to form a broad range of structures at given locations.
