Catalysts are everywhere. They make chemical reactions that normally occur at extremely high temperatures and pressures possible within factories, cars and the comparatively balmy conditions within the human body. Developing better catalysts, however, is mainly a hit-or-miss process.
(This is the first in a series about University of Pennsylvania students who took their arguments in support of federal student financial aid to Washington this summer in a project organized by the Office of Student Registration and Financial Services.)
Physicist Charlie Johnson connects the biological to the digital, using graphene and carbon nanotubes to turn chemical interactions into electrical signals. Johnson will explain how attaching biological structures, such as antibodies, to these flat or rolled-up lattices of carbon atoms has enabled him and his colleagues to build new kinds of sensors, detecting things like Lyme disease bacteria.
Olivia Lenz graduated from the University of Pennsylvania in May, but she is sticking around to continue something she started as a sophomore: seeking answers to the subtle cycle of sleep.

The inner workings of a cell involve hundreds of thousands of discrete molecules, engaged in a repeating cycle of interactions that sustain life.
The University of Pennsylvania has been named a project site for the Undergraduate STEM Education Initiative, a multiyear, multimillion dollar project that aims to improve the quality of education in science, technology, engineering and mathematics.
Several studies have shown that how much parents say to their children when they are very young is a good predictor of children’s vocabulary at the point when they begin school.
