Improved, Low-Stress Economical Submerged Pipeline

A preliminary study has shown that the use of a high-strength composite fiber cloth material may greatly reduce fabrication and deployment costs of a subsea offshore pipeline. Above-water pipelines are often not feasible due to safety, cost, and environmental problems, and present, fixed-wall, submerged pipelines are often very expensive.

Spectroelectrochemical Instrument Measures TOC

A spectroelectrochemical instrument has been developed for measuring the total organic carbon (TOC) content of an aqueous solution. Measurements of TOC are frequently performed in environmental, clinical, and industrial settings. Until now, techniques for performing such measurements have included, variously, the use of hazardous reagents, ultraviolet light, or ovens, to promote reactions in which the carbon contents are oxidized.

NASA Ames Research Center at Moffett Field, CA conducts critical research and development for the space agency, with a primary focus on supercomputing, networking, and intelligent systems. Recently, NASA Ames initiated work on the Sustainability Base, a $20.6-million facility designed to surpass standards for LEED Platinum™ sustainable design certification and approach net-zero energy consumption. When complete, it will be one of the federal system’s greenest buildings, and the first new NASA Ames facility in 20 years.

Technique Boosts High-Power Potential For Gallium Nitride Electronics

Gallium nitride (GaN) material holds promise for emerging high-power devices that are more energy efficient than existing technologies – but these GaN devices traditionally break down when exposed to high voltages. Now researchers at North Carolina State University have solved the problem, introducing a buffer that allows the GaN devices to handle 10 times greater power.

Combustor Computations for CO₂-Neutral Aviation

This method can be used to determine synthetic and biological fuels and blends.

Knowing the pure component Cp0 or mixture Cp0 as computed by a flexible code such as NIST-STRAPP or McBride-Gordon, one can, within reasonable accuracy, determine the thermophysical properties necessary to predict the combustion characteristics when there are no tabulated or computed data for those fluid mixtures or limited results for lower temperatures. (Note: Cp0 is molar heat capacity at constant pressure.) The method can be used in the determination of synthetic and biological fuels and blends using the NIST code to compute the Cp0 of the mixture.

Looking to Cow Rumen for Better Biofuels Enzymes

A cow's digestive system allows it to eat more than 150 pounds of plant matter every day. Now researchers report that they have found dozens of previously unknown microbial enzymes in the bovine rumen – the cow's primary grass-digestion chamber – that contribute to the breakdown of switchgrass, a renewable biofuel energy source.
