Optical cryocoolers, which are compact and produce no vibrations, are ideal for many electronics and sensor applications. In particular, some advanced metrology systems require cooling to around 124 K, the temperature at which the coefficient of thermal expansion for crystalline silicon goes through a null point. Currently, the dominant solid-state cooling technology is thermoelectric cooling, whi ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

The goal of this project is the formulation a rigid, insulating, low-density wood composite, with physical and thermal properties comparable to fossil fuel derived foams. _x000D_ _x000D_ To achieve energy conservation standards mandated by certification agencies such as Passive House and LEED, high performance buildings require multiple shells of insulation – an inner shell that contains electri ...

Need: People are exposed to formaldehyde, a carcinogen found in building materials. Highly sensitive, real-time formaldehyde sensors would improve human safety by alerting users to harmful concentrations. _x000D_ _x000D_ Technical Feasibility: Vaporsens produces chemical sensors based on novel organic nanofiber technology. Phase 1 results demonstrated high selectivity, rapid-response time, and dem ...

Large populations of interacting agents or swarms, are common throughout nature and society and, increasingly, in mechanical and electronic domains. Although the individual agents in such systems are governed by local rules, their collective behavior is often well-orchestrated to solve complex tasks, whether fighting disease, navigating through space to find resources, or to manage social interact ...

We propose to continue our project generating transgenic insect with improved nutrition for humans and livestock, building on the milestones we have reached and will continue to develop in phase I. We have already demonstrated insertion of exogenous reporter DNA into the insect, and continue to develop genetic engineering tools and techniques. We have expressed the biosynthetic pathway of interest ...

Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean burn limit (beyond which combustion is poor) restricts further emission reductions, the use of oxyg ...

DARPA is interested in demonstrating the capability of freeform fabrication systems to go beyond basic metal materials, such as stainless steel, and build advanced alloy components from CAD files without part-specific tooling or operator intervention. In this Phase I project, Lone Peak proposes to develop a titanium feedstock material and develop the SFF process for two rapid prototyping systems: ...
