Reducing the amount of carbon dioxide emissions from burning fossil fuels has been identified as one of the most important and difficult problems facing our society. The post combustion CO2 capture from flue gas is particularly challenging due to the relatively low pressure (1 atm) and high temperature (~70 ºC) of flue gas, and its small CO2 concentration (

Robots can drop pieces of plastic or metal in a pattern to build something but new software is needed to make the path the robot needs to follow. This work will build software that runs on high performance computers to determine the correct printing paths for the robots.

Supercritical CO2 power cycles are being developed for both utility-scaled power generation applications, as well as smaller waste heat recovery applications. Supercritical CO2 cycles are more efficient than current cycles, and the associated turbomachinery components are significantly smaller than that for current steam turbine-based power generation. However, sCO2 cycles operate at a combination ...

Several automotive industry changes are leading to the need for wide-range, high-boost turbocharging systems. Engine emission requirements require good turbocharger performance over a very wide range of flow rates. Trends in engine downsizing require turbochargers to have both good high flow performance, and good low flow performance, to cover a wide range of engine rpm operation. Current methods ...

According to a 2014 study commissioned by the Department of Energy, hydropower from the more than 3 million untapped streams in the U.S. could potentially generate 65 gigawatts of electricity and help to reduce greenhouse gas emissions and pollution. However, the development of hydropower has been limited by several obstacles, as described by the U.S. Geological Survey: most of the prime locations ...

High-temperature superconductors (HTS) are a vital technology for future particle accelerators, motors, generators and other electric power systems, fusion reactors, and many other medical and defense applications requiring high magnetic fields. One remaining limiting factor limiting to the implementation of HTS systems is the lack of adequate sensors to monitor the temperature and strain states o ...

Bennett Advanced Research proposes to examine fundamental properties of adaptive materials for use with Additive Manufacturing technologies. The focus will be on developing a system for spacecraft Self Health Monitoring (SHM).

Kyma Technologies, the leading domestic supplier of crystalline III-N substrate materials, is teamed with leading AlGaN materials & device experts at Sandia National Laboratory, to develop high-quality AlGaN templates in Phase I and free-standing AlGaN substrates in Phase II. Understanding that the commercialization potential of AlGaN templates and substrates requires a cost-effective and diameter ...

Optical limiters (OL) protect sensitive optical and electronic devices from laser-induced damage. The existing passive OL utilize nonlinear optical materials transmitting low-intensity light, while blocking laser radiation with intensity exceeding certain limiting threshold (LT). The common problem with the existing OL is that, at any particular frequency range, the choice of suitable nonlinear ...

The current surface activation process used to activate the surface of landing gear parts uses an aggressive grit blasting technique prior to electroplating. This technique is effective, but requires large amounts of blast media, requires a pre-cleaned surface and the process removes up to 0.1mils of substrate, much more than necessary. There is an urgent need for a process that can easily and eff ...
