Carbon Dioxide Measurements and Reference Materials

Ongoing
CO 2 Reference Materials The Gas Sensing Metrology Group at NIST has a long history of providing reference materials to industry, monitoring communities, and academia. The program began in the 1970’s by developing an initial suite of CO2 primary standard mixtures (PSMs) to support the US Department

Carbon Dioxide Removal Consortium

Ongoing
Industry is developing a variety of carbon capture and removal techniques including nature-based, hybrid, and engineered solutions. The scientific understanding, measurements, and models of these complex systems are still evolving. Furthermore, advanced technologies that enhance the applicability

Carbon Nanotube Reference Materials

Completed
Carbon nanomaterials are expected to play an important role in future technological developments of transistors, photovoltaics, transparent thin film conductors, sensors, and fuel cell electrodes among many potential applications. However, the potential of these materials has been hindered by a lack

Cardiac Device Reliability

Ongoing
Impact and Customers This project will reduce the need for surgeries to replace failed implants, thereby improving safety and quality of life for implant recipients and reducing medical expense to society. It will provide assessment tools for the external electronic devices that support the

CBRS Sharing Ecosystem Assessment

Ongoing
Background: In 2020, FCC auction 105 auctioned licenses in the Citizens Broadband Radio Service (CBRS). CBRS (3.55 GHz to 3.7 GHz) has a three-tiered framework to accommodate shared federal and non-federal use of the band. The DoD 3.5 GHz Transition Plans focus on ecosystem validations

CCQM Activities in the Gas Analysis Working Group

Ongoing
The results from these Key comparisons will be used to benchmark the appropriate Calibration and Measurement Claims (CMCs) of the participating NMIs. CMCs are basically the declared capabilities that an NMI offers to customers, and they are included in a searchable database at the BIPM web site

CCQM Activities in the Organic Analysis Working Group

Ongoing
The results from these studies will be used to demonstrate the capabilities of participating NMIs for their similar measurement services, and eventually benchmark the appropriate  Calibration and Measurement Capabilities (CMCs) that summarizes this capability.  NIST CMCs that directly support SI

Cell Line Authentication

Ongoing
Cell Line Authentication – The scientific community has responded to the misidentification of human cell lines with validated methods to authenticate these cells; however, there are few assays available for nonhuman cell line identification. We have developed multiplex polymerase chain reaction (PCR

Cell Viability for Advanced Therapies

Ongoing
In the Biosystems and Biomaterials Division at NIST, we have established several technical programs to support the development and implementation of cell viability assays in advanced therapies. These programs address key needs in cell viability assay development including selection and development

Cell-based Assay for Mechanistically-based Prediction of Cytoxicity

Completed
Ricin is a type 2 ribosome inactivating protein (RIP) belonging to the A-B family of toxins and is of particular interest because of its potential use as a biological weapon and the dearth of rapid and sensitive assays that could assist detection and decontamination. The ricin toxin inhibits protein

Cement Characteristics by Direct Phase Assessment

Ongoing
DESCRIPTION: The major research goal is the accurate prediction of field performance metrics from accurate characterization of mineralogical composition and texture. Compounding characterization and prediction problems is the widespread reliance since the 1930's on the Bogue estimates of composition

Certification of Three Soil SRMs for Inorganic Environmental Measurements

Completed
The three NIST soil SRMs, 2709, 2710 and 2711, have been used worldwide by hundreds of laboratories; combined sales typically exceed 800 units per year. Use of these SRMs provides our customers with tools that are essential for achieving quality assurance in the analysis of contaminant elements in

RF Channel Propagation Measurements and Models for Communications Circuits

Ongoing
The research community has long identified the need for propagation measurements to develop and evaluate communication circuits. Since 2011, NIST has been to prototyping state-of-the-art channel sounders for measuring RF channel propagation. NIST current channel sounders include LIDAR and camera

Characterization of Additive Manufacturing Materials

Completed
Objective: Deliver new standardized feedstock and AM-built material characterization methods, exemplar data, and databases to accelerate the design and use of additive manufacturing parts in high-performance applications (e.g., critical parts in high-stress applications such as turbine blades or

Characterization of 3D Photovoltaics

Completed
First Generation (thick layers of crystalline silicon) and Second Generation (thin films of CdTe, CIGS, and related materials) PV devices are both well established in the marketplace, with well defined techniques for fabrication and characterization. Third Generation PV encompasses a wide diversity

Characterized Authentic Drug Samples (CADS)

Ongoing
Project Overview The CADS project aims to provide academic researchers, forensic practitioners, and industry with curated and characterized panels of authentic seized drug samples for research, development, validation, and implementation purposes. In addition to making authentic samples available

Characterizing User Equipment Emissions

Completed
Designed, demonstrated and validated a test methodology for measuring aggregate emissions over a wide range of condition. Several factors were evaluated, including the collective power distributions emitted by the UEs in a cell, the number of UEs transmitting simultaneously, the spectral properties

Charpy Impact Machine Verification Program

Ongoing
The low cost and simple configuration of the test have made it a common requirement in codes for critical structures. However, the test is not useful if the variation in test results between laboratories is not tightly controlled. The control is accomplished by requiring the indirect verification of
