Perched atop a high plateau in Chile’s Atacama Desert, a long-awaited observatory is beginning to take shape: the largest suite of ground-based telescopes
Max Planck, one of the Twentieth Century’s most eminent physicists, observed, "An experiment is a question that science poses to Nature, and a measurement is
David Gerrold, a prolific American author, and screenwriter, summarizes the progress of the last 120 years when he observes, “In the 20th century, we had a
The Micro and Nanoplastic (MNP) Metrology Project aims to develop a toolbox of methods for size-based separations from complex matrices, chemical characterization protocols, and test materials necessary to enable quantification of micro- and nano-sized plastic particles, a need articulated by our
Semiconductor technologies are critical to U.S. economic and national security as they are essential to modern life in communications, healthcare, energy, etc. and also underpin many emerging technologies like quantum, artificial intelligence, high power electronics and advanced wireless (6G+). The
One type of device that is emerging as an attractive artificial synapse is the resistive switch, or memristor. These devices, which usually consist of a thin layer of oxide between two electrodes, have conductivity that depends on their history of applied voltage, and thus have highly nonlinear
This project focuses on manipulating nanomaterials, including weakly bonded van der Waals systems, and probing emergent phenomena in these nanoengineered systems to impact technologies such as nanoelectronics, optoelectronics, quantum sensing, and quantum computing. Developing processes to
