Projects and Programs

Microplastic and Nanoplastic Metrology

Ongoing

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

Nanoscale Spectroscopy for Advanced Electronics, Quantum Materials and Devices

Ongoing

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

GaN Nanowire Growth

Ongoing

Selective epitaxy: We have demonstrated that the diameter and placement of nanowires can be controlled by using silicon nitride (SiNx) masks on top of MBE-grown buffer layers (see figure). With electron beam lithography, several patterns with 3 mm die size that provide over 100,000 controlled

Comparing the Biological Responses of Photoluminescent Silicon Nanoparticles with Silicon Micron-sized Particles

Completed

Intended Impact Technology is now available to produce nanoparticles of uniform size and shape which may allow their use in a wide range of applications from drug delivery to water purification. The high surface area to volume ratio of nanoparticles makes them particularly good catalysts as well as
