designs. In addition to fabrication and characterization of these measurement tools, we also develop new readout schemes, signal and data processing, control systems, and biomimetic surfaces to improve
-
mechanistic investigations benefit from experimental and theoretical studies on model sample systems consisting of crystalline samples, ordered ultrathin films, or appropriately assembled biomolecules
-
NIST only participates in the February and August reviews. This project’s focus is to develop light-scattering nanoscopy methods for rapid, multi-attribute characterization of nanoparticles
-
details of regulatory mechanisms for ERK1/2 is a timely and important goal. Structural, biochemical, and biophysical experiments carried out by Natalie Ahn's lab and others have established key aspects
-
to meet these demands. NIST also researches methods to improve physical environmental measurements made to complement or validate space-based measurements. The NIST effort is aided by specialized facilities
-
frequency collective motions of biomolecular systems. These collective modes characterize the incipient motions for the large-scale conformational changes along the torsional coordinates responsible
-
particular, grating MOTs of diverse species like Li, Sr, or even molecules offer paths toward making new sensors. Our motivation is making a cold-atom based vacuum standard (CAVS) that also doubles as a vacuum

on these materials is analogous to that on synthetic quartz half a century ago, with much to be determined about crystal growth, defect evolution, and dependence on crystallographic orientation before high-performance
