PHILADELPHIA — Researchers at the University of Pennsylvania are participating in a massive, interdisciplinary collaboration known as the TerraSwarm Research Center, which will study the potential applications — and risks — of “swarm-based” computing and robotics.

Innovations in the realm of transportation technology have historically been physical; steam boilers gave way to internal combustion engines and then to electric fuel cells. But like most other technological landscapes, the field of transportation has undergone a digital revolution.

PHILADELPHIA — By showing that tiny particles injected into a liquid crystal medium behave as predicted by existing mathematical theorems, physicists have opened the door for the creation of a host of new materials with properties that do not exist in nature.

PHILADELPHIA — Directed assembly is a growing field of research in nanotechnology in which scientists and engineers aim to manufacture structures on the smallest scales without having to individually manipulate each component. Rather, they set out precisely defined starting conditions and let the physics and chemistry that govern those components do the rest.  

Liquid crystals have become a workhorse of technology; they are the standard for television and computer displays. In fact, there is a good chance you are looking at some liquid crystals right now.

PHILADELPHIA — The field of metamaterials involves augmenting materials with specially designed patterns, enabling those materials to manipulate electromagnetic waves and fields in previously impossible ways.

PHILADELPHIA — In the waning days of 2012, two words have dominated the post-election discourse: “fiscal cliff.” The cliff is a combination of impending budgetary measures that will take effect in January if a legislative compromise is not reached.

PHILADELPHIA – Five faculty members at the University of Pennsylvania have been named Fellows of the American Association for the Advancement of Science.  Two are from Penn’s Perelman School of Medicine, two are from its School of Arts and Sciences

PHILADELPHIA — One of the most promising innovations of nanotechnology has been the ability to perform rapid nanofabrication using nanometer-scale tips.  Heating such tips can dramatically increase fabrication speeds, but high speed and high temperature have been known to blunt their atomically sharp points.

PHILADELPHIA — Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications.  In a world where electronics are becoming more pervasive, flexibility is a highly desirable trait, but finding materials with the right mix of performance and manufacturing cost remains a challenge.
