Projects and Programs

X-ray Testbed for Breakthrough Catalyst Measurements

Ongoing

NIST’s Material Measurement Laboratory and Physical Measurement Laboratory are developing a first-of-kind X-ray testbed for operando monitoring of catalytic

Femtosecond Nonlinear Optical Spectroscopy of Nanoscale Materials

Ongoing

Condensed matter dynamics can evolve on a subpicosecond timescale, too fast to follow using many characterization techniques. We use femtosecond optical pulses

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

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

Ongoing

Conventional techniques for analyzing chemical composition, such as infrared (IR) microscopy often miss critically important nanoscale details. To overcome this
