The objective of the proposed project is to develop designs for manufacturable all-metal terminal hot-electron transistors (AMTHETs) that will enable 1W – 10W THz RF amplifiers and oscillators. The proposed work will focus on quantum-mechanical modelin...

In the US alone, 3 billion pounds of consumed fresh tomatoes are grown in greenhouse farms. These farms improve food security, require less land, and consume less resources; however, for these farms to operate, large labor forces are needed to maintain, harvest, and package the tomatoes. These jobs, though paying well above minimum wage, do not attract local workers and force farmers to use immigr ...

The importance of improving postharvest handling can be understood in terms of the primary impact of poor postharvest care--food loss. Technologies for improving postharvest handling focus on extending the shelf life of the fruit or vegetable while maintaining or improving upon the quality of the produce. A major achievement in prolonging produce storage life has been the implementation of cold st ...

As biodiesel production in the USA increases, bottlenecks in feedstock appear likely. Several companies have formed to investigate novel forms of conversion of lower cost feedstocks but all have found the same substantial hurdle, meeting the 15PPM sulfur specification of ASTM D6751. Numerous experiments have shown that low-cost fats, oils and greases may contain 300 - 500PPM sulfur and that no sin ...

The proposed research will evaluate the use of panoramic, street-level imagery to support and enhance community forestry. Similar to a windshield survey, these publicly available mapping resources can provide baseline data on tree species or genus, diameter, and condition that can be used to support future planting initiatives and best management practices. Furthermore, when combined with both man ...

Advanced Cooling Technologies, Inc. will develop a low-cost, high-efficiency condensation irrigation system to desalinate brackish water and provide affordable freshwater for agricultural applications. Solar thermal energy or low grade waste heat will be used to vaporize water from brackish water and humidify air; the hot humid air will then be sent to buried perforated condensation pipes and cond ...

There is growing consumer demand for "clean-label" food ingredients including color additives derived from natural sources. Colorant-related issues represent 3 of the top 10 concerns of consumers about food ingredients, and numerous food manufacturers and retailers have publically committed to removing synthetic food colors from their products. Fruit/vegetable-derived anthocyanins, carotenoids, an ...

High-speed flight vehicles commonly use carbon / carbon (C/C) and carbon / silicon carbide (C/SiC) for structural components. These materials are chosen because of their superior structural properties at elevated temperatures. Most often, their properties are characterized using flat and thin material test plates. While this approach is convenient, it is not guaranteed to yield material properties ...

Ultran will develop and prototype the transducer technology and initial system prototypes for a wearable system for imaging and modulation of peripheral nerves. Transducers developed for energy delivery will use Ultran's gas matrix piezoelectric (GMP) technology while those for imaging may use either GMP and piezoelectric micromachined ultrasonic transducers prototyped by a supplier. Miniaturized ...

Wearable, high image quality, low power, conformable ultrasound capable of delivering acoustic energy for nerve modulation
