Molecular Scrivener For Reading Or Writing Data To A Macromolecule

NIST Inventors
Joseph Robertson and Kin (Charles) Cheung
A molecular scrivener reads data from or writes data to a macromolecule and includes: a pair of shielding electrodes; a scrivener electrode between the first and second shielding electrodes and that electrically floats at a third potential that, in an absence of a charged or dipolar moiety of the
Depiction of Non-Resonant Electron Spin Resonant Probe And Associated Hardware

Non-Resonant Electron Spin Resonant Probe And Associated Hardware

NIST Inventors
Jason Campbell , Jason Ryan , Kin (Charles) Cheung , Robert Gougelet and Pragya Shrestha
This invention allows citizens to assess themselves (at the 2 Gy ± 0.5 Gy exposure level) using a dosimeter embedded in commercial and non-commercial identification cards. Patients can then seek appropriate action without the need for first responder and/ or public health official intervention. The

Electron Spin Resonance Spectrometer and Method for Using Same

NIST Inventors
Kin (Charles) Cheung and Jason Ryan
The new High Definition-E S R(HD-E S R ) spectrometer utilizes a superior detection scheme to perform electron spin resonance measurements. The major innovation centers on the use of a shorted coaxial “probe” (as small as a few nanometers) to excite the sample under test using near-field microwave

Phase Shift Detector Process for Making and Use of Same

NIST Inventors
Kin (Charles) Cheung , Jason Ryan and Jason Campbell
The detector senses very small phase shifts in a highly balanced microwave bridge. An electric field optimized microwave probe, in close proximity to a sample, serves to perturb the degree of bridge balance due to a .change in effective dielectric constant of the sample. The major innovation
