This project will develop a compact, robust low-power monitor for ethylene and other gases to enable space-based greenhouses.Human missions in space will require advanced systems to maintain an environment supporting human life, and smart greenhouses arenbsp;necessary for fresh food supply in long term space missions. Plants can produce ethylene through natural metabolic processes, and this ethyle ...

Harmful algal blooms can devastate ecological and economic systems; federal disasters are declared, public drinking water systems shut down, fisheries closed, and mass wildlife die offs and acute toxicity/death for humans occur. By the numbers, the negative financial impact of HABs globally is $10B and, as temperatures climb, conditions are increasingly favorable for HAB events. HABs can be contro ...

Tribo Flow Separations, LLC proposes a novel method for measuring nitrogen ground state densities and rotational temperatures of molecular nitrogen in the free stream of arcjet ground testing facilities through emission spectroscopy measurements. Knowlede of these quantities will reduce uncertainties in the knowledge of local specific enthalpy which, in turn, is the defining quantity for the deter ...

Human missions to the Moon and Marsnbsp;will require advanced systems to maintain an environment supporting human life. Smart greenhouses are necessary for fresh food supply in long term space missions. Through natural metabolic processes, plants can produce ethylene, which can accumulate in closed environments and have undesirable effects on the plants. These effects can include reduced growth, i ...

The overall goal of this project is to demonstrate the feasibility of 3D printing of ferrous, Cobalt, and Nickel-based alloys, using UHV’s innovative low temperature 3D printing technology for metals and alloys. This technology is based on electrochemical (co-)deposition of metallic ions at the tips of an array of electrolyte-containing nozzles, which are controlled by CAD files from a computer ...

APIQ Semiconductor proposes development of a scalable, wide bandgap (WBG) monolithic power integrated circuit (MPIC) technology for power electronic conversion, management, and distribution. The proposed WBG microelectronics are to be based upon low defect, homogeneous gallium nitride (GaN) based materials using native GaN substrates. The technology to be developed will replace silicon power switc ...

NASA recognizes the importance of conservation, smart utilization and reuse of resources for their deep space missions to address the need for regeneration of air, water and waste with highly reliable systems to reduce mission payload. Additionally, energy for life support and other systems needs to be obtained from renewable energy sources or waste streams. In order to address NASA's requirements ...

Longhurst Engineering, PLC, and Vanderbilt University propose an in-space friction stir welding (FSW) machine for joining complex structural aluminum components. The proposed FSW machine is innovative because it can be deployed by 2 people and be used to weld complex surfaces that extend beyond linear welding applications. The in-space FSW machine is a 3 axis system that can be mounted to work p ...

This program will focus on developing and validating computational models for near-net shape processing of aluminum alloys. Computational models will be developed for deformation modeling and for texture generation. Characterization of two aluminum alloys including flow stress, forgeability, and recrystallization characteristics will provide input for the models. The models will be validate thr ...

Designing complex systems, such as those used by NASA, requires a coordinated effort among a variety of engineering teams. In order to be successful, the human-computer interactions in these systems need to follow a principle-based design process. In Phase II, TiER1 and Alion propose to continue development on HFE-AT, renaming it and creating a Human Factors Analysis Support Tool (H-FAST), which ...
