As computational density for high- performance computing and big-data services continues to scale, performance scalability of next generation computing systems is becoming increasingly constrained by limitations in memory access, power dissipation and chip packaging. The processor-memory communication bottleneck, a major challenge in current multicore processors due to limited pin-out and power bu ...

Cost-effective and power-efficient radiation tolerant semiconductors are needed in various harsh environments, such as particle detectors, communication satellites, high-altitude avionics and medical imagining equipment. These include amplifiers, voltage regulators, analog-to-digital converters (ADCs) and digital logic circuitry. However, radiation-tolerant high-speed ADCs currently cost more than ...

Development of accelerator structures that can sustain acceleration gradients up to 150 MeV/m are required in order to build a future multi-TeV collider with an energy reach beyond present or planned electron-positron colliders. Limitations for operation with high acceleration gradient arise from RF breakdown. High-melting-point insulated coatings are to be applied first to test samples and to p ...

Separations often account for a majority of process costs. This is because all traditional separation processes have inherent weaknesses that prevent the system from achieving perfect (or even near perfect in many instances) selectivity. These weaknesses result in large recycle streams and require multiple separation units in concert in order to produce a product clean enough for use or sale. An a ...

An important objective of the NEAMS program is to enable widespread use of the software tools among the industry, academia, and regulatory communities. For solving the problems occurring at various stages of NEAMS simulations, typically there are several possible choices for numerical subroutines. Furthermore, the best method for a numerical problem may also evolve over the course of the simulatio ...

Neutron scattering is one of the most useful methods of studying the structure and dynamics of matter. These methods require large installations at national laboratories, such as Oak Ridge National Laboratory (ORNL), National Institute of Standards and Technology (NIST) and other facilities constructed or planned in the US and around the world. These facilities serve a large and diverse community ...

Providing Army combat medics with meaningful experience in treatment of battlefield injuries is a particular challenge. Moulage has the potential to assist in acquiring what could otherwise be very hard-to-come-by preparatory experience for distressing real-life emergencies medics and soldiers may encounter in the field. However, current approaches to moulage are limited in their ability to reflec ...

Redox flow batteries are a promising technology for electrical energy storage for renewable energy sources; however traditional redox flow batteries are limited in their use due to non-uniform pressure drops and mass transfer limitations, as well as high manufacturing costs related to the felt material costs for the electrode and component alignment challenges during manufacturing.General Statemen ...

Under the Department of Energy’s Ground-based Nuclear Detonation Research and Development (GNDD R&D) Program, the Air Force Technical Application’s Center (AFTAC) monitors for nuclear explosions through high altitude whole-air gas sampling using compressors to inject air into a high-flow air stream or store in a high-pressure vessel. The existing compressors have proven reliability issues with ...

Indium tin oxide (ITO) films are currently the most widely used transparent conductor in optoelectronic applications. However, ITO suffers from several major technological and economic limitations for large area applications such as inadequate performance, high cost, and brittleness. The primary objective of this Small Business Technology Transfer (STTR) Phase I/Phase II project is to develop the ...
