MNP Metrology Program

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
PTIR combines the spatial resolution of AFM with the specificity of absorption spectroscopy

Nano-Chemical Imaging and -Spectroscopy (IR, nIR, VIS)

Ongoing
The aim of this project is twofold: 1) improve the PTIR measurement (spectral range, signal to noise ratio, throughput, time resolution, information content, range of environmental conditions) and 2) apply PTIR to characterize nanomaterials in important applications. Examples or recent PTIR
nanowires

GaN Nanowire Metrology and Applications

Ongoing
GaN Nanowire LEDs: Our selective epitaxy methods and dopant characterization techniques have enabled fabrication of arrays of nanowire LEDs with controlled location and spatial layout. This development is complemented by modeling of the carrier flow and recombination. These LEDs were combined to

Nanoscale Thermal Properties

Completed
It is known that at the nanoscale, composition and interface structure play important roles in determining the mechanical, thermal, and electrical properties of multiphase nanomaterials and nanocomposites. To probe the thermal properties of these heterogeneous nanomaterials, local thermal analysis
