Penn Produces Graphene Nanoribbons With Nanopores for Fast DNA Sequencing

The instructions for building all of the body’s proteins are contained in a person’s DNA, a string of chemicals that, if unwound and strung end to end, would form a sentence 3 billion letters long.

Penn and Drexel Team Demonstrates New Paradigm for Solar Cell Construction

For solar panels, wringing every drop of energy from as many photons as possible is imperative.  This goal has sent chemistry, materials science and electronic engineering researchers on a quest to boost the energy-absorption efficiency of photovoltaic devices, but existing techniques are now running up against limits set by the laws of physics.

Researchers at Penn Add Another Tool in Their Directed Assembly Toolkit

An interdisciplinary team of University of Pennsylvania researchers has already developed a technique for controlling liquid crystals by means of physical templates and elastic energy, rather than the electromagnetic fields that manipulate them in televisions and computer monitors. They envision using this technique to direct the assembly of other materials, such as nanoparticles.
