The newly-opened (Oct. 4, 2013) 78,000 square-foot Krishna P. Singh Center for Nanotechnology serves as Penn's focal point for nanoscience research and technology-development. P&A's Prof. Jay Kikkawa was instrumental in the planning and provision of vital services for the new facility.
Sudbury Neutrino Observatory
The Sudbury Neutrino Observatory (SNO) is a second generation dedicated solar neutrino experiment which has extended the results of the Penn group with the Kamiokande II detector by measuring three reactions of solar neutrinos to fully resolve the solar neutrino problem.
Reflective Self-Assembling Proteins
Prof. Alison Sweeney studies the biophysical properties of reflectin - a highly reflective and self-organizing squid protein found in cephalopods like the Hawaiian Bobtail squid shown here.
Bio-optics and bio-optical materials
Prof. Alison Sweeney and her colleagues believe that the reflective structures in giant clams help them grow algae. The clams use sub-wavelength structures formed from a protein called reflectin to optimize the photosynthesis of the algae living in the clam tissues.
Blinking Semiconducting Nanorods
Several clusters of semiconducting nanorods are being illuminated by blue light. The nanorods absorb blue light, become excited and emit red light. The emission of light by individual nanorods occurs in a random fashion with the nanorod turning "on" and "off" for variable lengths of time.
Johnson, a professor of physics, has a career that has ranged from the
basic science of nanomaterials through some very practical applications
of them. He has pioneered and commercialized manufacturing techniques
that make mass production of graphene for research and other uses
possible, continues to pin down the mechanisms underlying the tiny
materials’ properties, and has worked to incorporate biology and
chemistry with nanotech in ways that could offer big steps forward in
everything from health diagnostics to environmental monitoring.
