Cold Core Technology Platform

Ongoing
Cold atoms can be useful sensors for a host of different phenomena including inertial forces like acceleration and rotation, gravity, magnetic fields, vacuum and time. However, most of these applications are still confined to the laboratory. Building robust, field-deployable quantum sensors made

Collaborative Microgrid for Smart Buildings

Completed
Currently, the idea of designing collaborative smart buildings is becoming a real challenge. Indeed, the emergence of smart grids and the growing use of smart household appliances is the main driving force behind the use of demand side management. This would require developing an efficient control

Collaborative Research with NIST Scientists and Engineers

Ongoing
As members of interdisciplinary teams, SED statisticians contribute in a variety of ways. SED staff develop appropriate statistical strategies to meet the needs of the research teams, participate in the planning of experimental studies, and conduct rigorous and nontrivial uncertainty analysis of

Collapse Assessment of Buildings under Seismic Loading

Completed
Objective - To evaluate the collapse probabilities of a suite of steel buildings for a series of increasingly severe earthquake ground motions, and to compare these probabilities to the collapse objective presumed in ASCE/SEI 7. The probabilities of collapse will be determined using the methodology

Combating Antibiotic Resistance

Ongoing
We are developing in vitro systems to generate controlled chemical and community environments that mimic the features of real-world that are important determinants for evolutionary rate and resistance potential. In addition, we are developing tools to isolate and analyze single bacteria along the

Combinatorial Approaches to Thin Film Nanomaterials

Completed
The behavior and performance of nanostructured materials and devices are governed by the chemistry and structure of their surfaces and interfaces. However, chemistry-structure-performance relationships in these systems are complex, so hundreds of experiments can be necessary to determine optimal

Commissioning Building Systems for Improved Performance and Cybersecurity

Ongoing
Objective To improve the performance of building systems by providing the measurement science needed to develop improved building commissioning techniques that utilize embedded capabilities of building control systems, accelerate the adoption of cost-effective commissioning as standard practice and
NIST

Community Resilience Program

Ongoing
Objective - By 2028, deliver novel resilience planning and analysis methods and tools to support informed decision making by communities of all sizes. By 2028, implement multifaceted outreach, collaboration, and engagement to ensure the effective dissemination of community resilience guidance

Compact Cold Atom Instruments

Ongoing
Chip-scale laser cooling This project develops technologies to achieve chip-scale laser cooling, beyond direct miniaturization of existing laboratory techniques. This includes development of the vacuum technology for realizing low power, passively pumped ultra-high vacuum chambers [1,2] and novel
optical clock

Compact strontium optical clock with integrated photonics

Ongoing
The development of a liter-scale apparatus to produce Sr, would enable highly accurate, transportable optical clocks based on their ultra-narrow optical transition. However, straightforward miniaturization of the traditional optical infrastructure necessary to implement multi-step laser cooling has
Compact ultrastable optical references illustration

Compact Ultrastable Optical References

Ongoing
At the heart of any stable laser is a reference cavity resonator. By locking a laser’s frequency to a reference cavity mode, the laser inherits the resonator’s stability. These stable lasers can then be used in various sensing and spectroscopy applications, including in optical atomic clocks and

Comparative Mammalian Proteome Aggregator Resource (CoMPARe) Program

Ongoing
Comparative proteomics strives to gain insight into key underlying molecular changes that result in unique phenotypes across related taxa. Proteomic analysis complements comparative genomics by providing evidence of protein abundance, orthogonal to gene copy number and amount of transcript. To
Serum Project Logo

Comparative Serum Proteomics Project

Ongoing
State-of-the-art biomolecular analysis is no longer limited to model organisms and is becoming routine in non-model organisms. Major drivers of this emerging bioanalytical capacity include increasing accessibility and quality of sequenced genomes as well as high-resolution fast-duty cycle mass

Comparison: Co-60 Absorbed Dose for High-Dose Dosimetry

Completed
The NIST comparison demonstrated the need to know the participant's calibration scheme and dose rates, as well as the inclusion of an additional dose level (1 kGy, in addition to 5 kGy, 15 kGy, and 30 kGy). The rationale for modifying the protocol was based on the recent NIST characterization of a

Comparison of Internet Congestion-Control Algorithms

Completed
Complex systems are generically characterized by a large number of factors and a large number of potential responses, hence statistical questions immediately present themselves as to 1. What should be measured? 2. What experiment design should be used to generate content-full data? 3. How should

A Comparison of WD-EPMA Heterogeneity Testing Procedures

Ongoing
X-ray stage mapping (XSM) can be used to determine the extent of heterogeneity on the micron scale though it is more time consuming and not as accurate as the more rigorous NIST random-point (RP) testing procedure. The objective of this work is to demonstrate the advantage of the latter procedure
