CRYOGENIC HELIUM REFRIGERATORS AND LIQUIFIERS CONVENTIONALLYEMPLOY OIL LUBRICATED POSITIVE DISPLACEMENT COMPRESSORS AT THE WARM END AND FREQUENTLY USE PISTON TYPE EXPANSION ENGINES AT THE COLD END. THESE SYSTEMS REQUIRE EXTENSIVE AND VIGILANT MAINTENANCE TO CONTROL CONTAMINATION FROM LUBRICATING OIL AND ITS VOLATILE COMPONENTS MIGRATING TO THE COLD END. HENCE THE NEED FOR LOW MAINTENANCE COMPRESSO ...

The changing global nuclear security landscape requires new imaging tools for remote detection applications. Integrating multiple imaging applications into one sensor has that advantage of reducing unmanned aerial vehicle payloads which can result in enhanced, streamlined data collection with fewer flights. While gathering different optical field signatures such as intensity, wavelength, and polar ...

Argonne National Laboratory has pioneered a new method for additively manufacturing MCPs and functionalizing their channels with atomic layer deposition. We will help extend their technology to particle detection at Nuclear Physics facilities for beam tuning and test a prototype detector at the ATLAS facility.

Under this Phase II grant, NuMat Technologies (NuMat) will continue to develop metal-organic frameworks as point-of-use hydrogen purifiers. These purifiers, once realized, will be deployed to ensure high purity hydrogen is delivered to fuel cell electric vehicles (FCEVs). Data collected at the National Renewable Energy Laboratory has shown that hydrogen purity at fueling stations can be lower than ...

Power electronics for Grid-tied Battery Energy Storage Systems (BESS) featuring: (a) newly developed monolithically integrated High Voltage SiC MOSFET- Schottky Diodes; (b) Intelligent Gate Drivers that provide in-situ monitoring and restoration capabilities; and (c) novel three level Neutral point clamping topology are proposed. An isolated topology such as dual active bridge followed by an activ ...

IN MOST CRYOGENIC SYSTEMS, THE PIPING JOINTS IN COLD REGIONSOF THE SYSTEM ARE MADE BY WELDING OR SOLDERING. THIS IS ESSENTIAL BECAUSE EXISTING DESIGNS OF CRYOGENIC PIPE SEALS CANNOT BE RELIED ON NOT TO LEAK. ANY SUCH LEAKS INTO THE COLD BOX REDUCE THE EFFECTIVENESS OF THE INSULATION, THEREBY REDUCING THE EFFICIENCY OF THE REFRIGERATOR. WELDEDJOINTS MAKE REPLACEMENT OF COMPONENTS DIFFICULT AND HAVE ...

The primary goal of this proposed work is to develop a long wavelength infrared (LWIR) colloidal quantum dot (CQD)-based focal plane array (FPA) and show its feasibility when used in a camera system and a hyperspectral imaging system. Phase I results cumulated in the first-ever synthesis of photoresponsive LWIR CQDs and CQD-based photodetectors at the single device level operating at room temperat ...

The proposed low-SWaP PAPR technology improves the convenience, comfort, and protection level for respirators used in low-threat hazardous environments. Creare’s PAPR technology will be applicable to a variety of respiratory protection needs, including emergency escape, laboratory and field work in low-hazard conditions, and some combat and combat support activities. The PAPR will improve user f ...

Chemical, biological, or toxin attacks in military and civilian settings are a serious and growing concern. Standard first aid for exposure to some chemical warfare agents and toxins includes the immediate administration of relevant antidotes using an autoinjector. When an attack occurs, pre-filled autoinjectors must be immediately available and thus highly portable, and they must be suitable fo ...

Such broad use has long been inhibited by tool complexity and by the fact that simulation and data analysis tools require complex pre- and post-processing and parallel workflow orchestration. Tedious tool installation procedures and complex parallel platform and data management requirements add further impediments to technology transfer and industrial adoption. Parallel Works Inc. has created a We ...
