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.
Graduate students Elizabeth Beattie, Nick Parrotta, Nick McGill and Niko Vladimirov of the School of Engineering and Applied Science are featured for winning the 2013 James Dyson Award for their Titan Arm invention.
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.
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.
