The University of Pennsylvania (Penn or UPenn) is a private Ivy League research university in Philadelphia, Pennsylvania. Founded in 1740, it is one of the nine colonial colleges founded prior to the Declaration of Independence and the first institution of higher learning in the United States to refer to itself as a university. Benjamin Franklin, Penn's founder and first president, advocated an educational program that trained leaders in commerce, government, and public service, similar to a modern liberal arts curriculum. The university has four undergraduate schools as well as twelve graduate and professional schools. Among the university's professional and graduate schools are the first school of medicine in North America (Perelman School of Medicine, 1765), the first collegiate business school (Wharton School, 1881) and the first "student union" building and organization (Houston Hall, 1896). In 2018, the university had an endowment of $13.8 billion, the seventh largest endowment of all colleges in the United States, as well as an academic research budget of $966 million.

Growing ‘Metallic Wood’ to New Heights

“Natural wood remains a ubiquitous building material because of its high strength-to-density ratio; trees are strong enough to grow hundreds of feet tall but remain light enough to float down a river after being logged. For the past three years …

New strategies for designing electroluminescent materials

“A collaborative team of materials scientists and theoretical chemists provide hybrid perovskite nanoparticles that are high-efficiency light emitters by using a comprehensive defect-suppression strategy. New research details how a class of electroluminescent materials, key components of devices such as LED …

Engineers manipulate color on the nanoscale, making it disappear

“Most of the time, a material’s color stems from its chemical properties. Different atoms and molecules absorb different wavelengths of light; the remaining wavelengths are the “intrinsic colors” that we perceive when they are reflected back to our eyes …

State-of-the-art lasers at the micro level

“New filter chips created by Penn engineers could enable high-quality lasers at a fraction of their current size and cost. Many emerging technologies rely on high-quality lasers. Laser-based LiDAR sensors can provide highly accurate scans of three-dimensional spaces, and as …

New scavenger technology allows robots to ‘eat’ metal for energy

“When electronics need their own power sources, there are two basic options: batteries and harvesters. Batteries store energy internally, but are therefore heavy and have a limited supply. Harvesters, such as solar panels, collect energy from their environments. This gets …

Revealing ‘hidden’ phases of matter through the power of light

“New research shows how materials can be imbued with new chemical properties using a solid phase transition method that relies on extremely fast pulses of light. Most people think of water as existing in only one of three phases: solid …

Engineers 3D print smart objects with ‘embodied logic’

“Even without a brain or a nervous system, the Venus flytrap appears to make sophisticated decisions about when to snap shut on potential prey, as well as to open when it has accidentally caught something it can’t eat. Researchers …

Shining Light on the Separation of Rare Earth Metals

“New studies identify key molecular characteristics to potentially separate rare earth metals cleanly and efficiently with light. The Science Inside smartphones and computer displays are metals known as the rare earths. Mining and purifying these metals involves waste- and energy-intense …

Paving the way for safer smaller batteries and fuel cells

“Fuel cells and batteries provide electricity by generating and coaxing positively charged ions from a positive to a negative terminal which frees negatively charged electrons to power cellphones, cars, satellites, or whatever else they are connected to. A critical part …

Penn Engineering Research Gives Optical Switches the ‘Contrast’ of Electronic Transistors

“Current computer systems represent bits of information — the 1’s and 0’s of binary code — with electricity. Circuit elements, such as transistors, operate on these electric signals, producing outputs that are dependent on their inputs. ​​​​​​​As fast and powerful …
