Naomi Ginsberg, professor of chemistry and physics at UC Berkeley, credits her love of learning as the driving force behind her unusual academic journey. In her first year of college, she studied engineering because it was, as she explains it, “technical, but also creative.” However, a summer research internship studying magnetic resonance—a backbone of modern medical imaging— opened her eyes to creative problem solving in basic science.
University of California, Berkeley, scientists have created a blue light-emitting diode (LED) from a trendy new semiconductor material, halide perovskite, overcoming a major barrier to employing these cheap, easy-to-make materials in electronic devices.
A breakthrough by Peidong Yang could one day help tall buildings use dramatically less energy, by using their windows to generate electricity. For the full story visit ABC7 News.
Scientists have long sought to mimic the process by which plants make their own fuel using sunlight, carbon dioxide, and water through artificial photosynthesis devices, but how exactly substances called catalysts work to generate renewable fuel remains a mystery.
M. thermoacetica first made its debut as the first non-photosensitive bacterium to carry out artificial photosynthesis in a study led by Peidong Yang, a professor in UC Berkeley’s College of Chemistry. By attaching light-absorbing nanoparticles made of cadmium sulfide (CdS) to the bacterial membrane exterior, the researchers turned M. thermoacetica into a tiny photosynthesis machine, converting sunlight and carbon dioxide into useful chemicals.
With the right technology, the gas station of the future will make its own fuel directly from sunlight, in the process sucking up carbon and producing oxygen. Decades into the future, the same technology could provide fuel and oxygen for the first Martians, and could even be tweaked to produce fertilizer....
Peidong Yang, a professor of chemistry and faculty scientist at Berkeley Lab, and his colleagues have tweaked the chemical structure of perovskite — a versatile material that already rivals silicon-based solar cells — so that the material turns from transparent...
