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

Combinatorial Testing

Ongoing

Commissioning Building Systems for Improved Energy Performance

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

Commissioning of the PERFORM Structural Testbed Project

Ongoing
Objective - To establish, maintain, and continually enhance the support infrastructure required to safely conduct measurements on the performance of structures under multiple hazards with quantified uncertainty. What is the new technical idea? The modular, reconfigurable PERFORM Structural

Community Resilience Program

Ongoing
PROGRAM OBJECTIVES: To develop science-based tools for communities, professionals, and researchers to assess resilience and to support informed planning and decision making at the community scale for improving resilience in communities of all sizes. To conduct a multi-faceted outreach effort to

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

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

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

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

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

Comparisons (Archive): International Comparison of Pu-241 Activity

Completed
Quantitation of 241Pu in low-level waste and environmental samples is of interest because 241Pu is a precursor of other transuranium nuclides that have longer half-lives, greater environmental mobility, and greater toxicity. In addition, 241Pu is the most difficult of the plutonium isotopes to

Comparisons (Archive): International Comparison of Tc-99 Activity

Completed
Measurements by NIST on the solution were performed by three methods: viz., liquid scintillation (LS) standardizations (with 3H-standard efficiency tracing); with triple-to-double-coincidence ratio (TDCR) method; and with by 4ηβ(LS)-γ(NaI) live-timed anticoincidence (LTAC) measurements. Impurities
