A team of material scientists, chemical engineers and physicists from the University of Pennsylvania has made another advance in their effort to use liquid crystals as a medium for assembling structures.
During the past five years, the number of international students at the University of Pennsylvania has seen record growth at the undergraduate and the graduate level. Penn is among the top destinations for international students from around the world seeking to study in the United States. Currently, the University hosts 5,751 international students from 137 different countries, including China, Japan, Thailand, Canada, Taiwan and Singapore.
The idea of growing replacement tissue to repair an organ, or to swap it out for an entirely new one, is rapidly transitioning from science fiction to fact.
The heart maintains a careful balancing act; too soft and it won’t pump blood, but too hard and it will overtax itself and stop entirely. There is an optimal amount of strain that a beating heart can generate and still beat at its usual rate, once per second.
The blood stem cells that live in bone marrow are at the top of a complex family tree. Such stem cells split and divide down various pathways that ultimately produce red cells, white cells and platelets.
With a gift of $15 million, University of Pennsylvania trustee emeritus P. Roy Vagelos, C’50, Hon’99, and his wife, Diana, parents ’90, are continuing to ensure Penn’s leadership in energy research by endowing two professorships dedicated to this critically important field.
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.
The Institute of Medicine and the National Research Council today released a comprehensive report on sports-related concussions in youth, detailing factors associated with increased rates of the brain injury, the effectiveness of protective devices and new screening, diagnosis, treatment and management techniques, as well as the long-term consequences of concussions.
On Wednesday, Oct. 23, the University of Pennsylvania’s Nano/Bio Interface Center will host its annual NanoDay@Penn. This public education and outreach event will feature a series of talks, demonstrations and exhibits dealing with nanotechnology, a rapidly expanding scientific discipline that involves the manipulation of matter on the atomic and molecular scale.
In an Op-Ed, Vukan R. Vuchic of the School of Engineering and Applied Science says that Philadelphia should make transit more accessible rather than striving to accommodate more cars.
