Water Heating System With Legionella Control

NIST Inventors
David A. Yashar
A bacteria abatement water heater abates bacterial growth and includes a fluid-isolated heat exchanger; a water heating container that heats water to a high water temperature that is greater than or equal to a kill temperature for bacteria; a hot water delivery conduit including a transitional
Cell design showing both cell walls and windows made of non-conducting glass. A thin layer of polysilicon deposited on the glass is used for bonding the cell closed.

Atomic Vapor Cell And Making An Atomic Vapor Cell

NIST Inventors
Christopher L. Holloway , Alexandra (Aly) Artusio-Glimpse , Vladimir Aksyuk and Matt Simons
A new method for fabricating cells at the wafer level that minimizes the amount of silicon. Instead of fabricating the frame onto which glass is bonded out of silicon, we start with a glass wafer, in which holes have been etched or abrasively machined. A thin layer of polysilicon is deposited onto

Optomechanical Accelerometer And Performing Optomechanical Accelerometry

NIST Inventors
Jason J. Gorman , Thomas W. LeBrun and David Long
An optomechanical accelerometer includes: a fiducial mass for a microscale Fabry-Perot optical cavity; a proof mass for the microscale Fabry-Perot optical cavity, such that the proof mass oscillates in a displacement motion toward and away from the fiducial mass in response to acceleration of the

Calibration Apparatus And Calibrating A Laser Doppler Vibrometer

NIST Inventors
Michael Gaitan , Benjamin Reschovsky and Akobuije Chijioke
A new approach to characterize the performance of a laser Doppler vibrometer (LDV). The method uses two acousto-optic modulators to frequency shift the light from an LDV by a known quantity to create a synthetic velocity shift that is traceable to a frequency reference. Results are presented for

Quantum Flow Cytometer

NIST Inventors
Sergey Polyakov and Ivan Burenkov
A quantum flow cytometer for detecting an analyte with photon-number statistics includes: a flow cytometer that: receives a pump light in a first direction; receives an analyte flow comprising the analyte in a second direction; and produces scattered light from scattering the pump light by the

Methods For Electrically Charging Nanocrystals At Very Large Areas

NIST Inventors

Methods are disclosed for uniformly charging nanocrystals. Using these methods large area interfaces per nanocrystal can be formed for electrically powering or operating nanocrystals. The formed metal- interfaces, including metal- semiconductor and semiconductor- semiconductor, are structurally

Body Cube And Process For Culturing Tissue

NIST Inventors
Mandy B. Esch, PhD
A body cube for culturing tissue that includes: an organ chip holder; and a body barrier chip and a first body organ chip disposed in the organ chip holder, the first body organ chip including a first cell culture chamber that receives cell culture medium and produces a first tissue in the first

Synchronizer And Synchronizing Transfer Over An Optical Link

NIST Inventors
Laura Sinclair , William C. Swann and JD Deschenes
A synchronizer for synchronizing transfer over an optical link includes a frequency reference oscillator; a tracking optical timing source; a tracking comb signal; a signal processor-controller; a comb timing discriminator; a clock frequency comb; a bidirectional terminal; a time-frequency offset

Dry Prelithiation Of Electrode Materials For Lithium Batteries And Supercapacitors By Controlled Dose Low Energy Implantation Of Lithium Ions

NIST Inventors
Christopher Soles , Vladimir Oleshko and Jabez J McClelland
In this disclosure, we describe a method of creating new and improved battery electrodes by doping conventional battery electrode materials with dry lithium (Li+) ions, using ion implantation techniques under vacuum. This dry "prelithiation" step will both (a) increase the amount of active Li+ in

Nearly Optimal Time-Independent Reversal of a Spin Chain

NIST Inventors
Alexey Gorshkov
This technology is a time-independent protocol that reverses the order of qubits in a chain (e.g., changing the order $1, 2, 3$ to $3, 2, 1$). It uses a pre-engineered "Hamiltonian"—a specific set of fixed magnetic fields and interactions between neighboring qubits—to naturally evolve the system
