A list of radiation-induced materials modifications that are NIST traceable

Photonic Dosimeter and Process for Performing Dosimetry

NIST Inventors
Ronald Tosh , Zeeshan Ahmed , Ryan P. Fitzgerald and Nikolai Klimov
Patent Description Radiation-induced materials modification is ubiquitous. These applications rely on dosimetry to reliably deliver the desired amount of radiation to the right place. Currently the dosimetry standard is based on calorimetry of a large water phantom irradiated exclusively by Co-60

Neural Member, Neural Network, and Neurological Memory

NIST Inventors
Stephen E. Russek , William Rippard and Matthew Pufall
Patent Description We propose a new form of artificial synapse based on dynamically reconfigurable superconducting Josephson junctions with magnetic clusters in the barrier. The spiking energy per pulse varies with the magnetic configuration. The critical current of each magnetic Josephson junction

Measuring a size distribution of nucleic acid molecules in a sample

NIST Inventors
Craig Copeland and Samuel M. Stavis
Patent Description This invention is a method for measuring the size of single nucleic-acid molecules. Measuring the size of nucleic-acid molecules is important in a variety of applications ranging from criminal forensics to clinical diagnostics. The invention advances conventional methods and
This is a line drawing for patent number 10,625,470

3D Printing of Composition-Controlled Copolymers

NIST Inventors
Young Jong Lee
Patent Description This invention is a new 3D printing process of continuously or discretely controlling composition of photo-polymerization reactants to produce 3D objects with spatially varying chemical, physical and mechanical properties. This invention is based on photo­ polymerization of liquid
Line drawing of high efficiency photon detection

High Efficiency Photon Detection

NIST Inventors
Alex Smolyanitsky
Patent Description A detection pixel includes a material that is chosen so that its (averaged) atomic number density leads to the Compton process being the dominant scattering mechanism in response to incident photons, leading to production of Compton electrons with sufficient number and kinetic
