Measurement of vital signs (VS) is essential to assess the condition of human body. VS includes body temperature (Tc), heart (pulse) rate (HR), respiration rate (RR) and blood pressure (BP). VS are useful in detecting medical problems. Typically VS measurement and monitoring takes place in a controlled setting like hospital, clinic or home using bulky contact based machines. In order to monitor VS ...

Geothermal is a critical, yet underutilized, resource for our nation’s climate and energy goals. Geothermal, like other new technologies whose socioeconomic impacts are not fully understood, may cause disproportionately high adverse effects on disadvantaged communities. This is especially true if the process does not fully account for their socioeconomic and cultural interests and concerns. Unfo ...

The development of next-generation materials for Li-ion batteries is a highly significant problem and opportunity with far-reaching implications for the future of energy storage and electrification. Graphite is a known suboptimal anode material due to low charge rates and limited specific capacity. While replacing graphite with silicon increases the specific energy density (Wh/kg) by a maximum of ...

The cost of capturing CO2 from coal-derived flue gas using existing technologies, like absorption far exceeds the DOE's target of around $30-40/ton of CO2. To overcome this hurdle, a novel transformative block copolymer membrane has been developed, which contains microporosity using rubbery polar polymers with nanoparticles. This membrane has the potential to achieve exceptional CO2 permeance (450 ...

The conventional nitric acid manufacturing method uses natural gas as a feedstock for hydrogen and an energy intensive thermal process that emits a large amount of carbon dioxide. A new low-temperature plasma system, which can be driven electrically by a renewable or nuclear energy source, could reduce the energy consumed by the synthesis of nitric acid while eliminating the emission of greenhouse ...

Problem Statement and Approach: Sensitive detection of electromagnetic (EM) fields at microwave frequencies underlies crucially many high-energy physics (HEP) experiments that rely on the measurement of weak couplings between ultralight dark matter and electromagnetism. These HEP experiments require the sensing of EM fields down to single photon level, which, unfortunately, remains a significant c ...

Energy storage is required to address variability in supply and demand of electricity, while transitioning to a renewable-intensive grid, electrifying transportation, and electrifying heat. Buildings have high energy demands for heating, ventilation, and air conditioning (HVAC). Thermal Energy Storage (TES) can store off-peak/renewable-intensive for later use in heating or cooling the host buildin ...

A major barrier to advances of machine learning (ML) and artificial intelligence (AI) in manufacturing and largescale DOE facilities is incomplete and inaccurate data sets. The proposed distributed framework offers a versatile, high-performance, and extremely scalable data consolidation platform, adept at handling vast amounts of data. The "data mesh" or "distributed data lake" architecture allows ...

Despite ambitious targets set by businesses and government to reduce emissions and improve sustainability, industries lack the scalable technologies to achieve these goals. While promising methods to capture and convert CO2 into value-added products including fuels and chemicals have been commercialized, these pathways are thermodynamically uphill, energy-intensive, and require temperatures above ...

C56-02a-272165Source-based (Cs-137 or Co-60) calibration systems produce gamma radiation fields of known energy and intensity for calibration of radiation monitoring equipment, dosimeters, and industrial/medical radiation technologies to ensure their accurate operation. These calibration systems are essential for the safe and correct use of such devices. However, the use of high- activity radioiso ...
