Combining Air Capture and Water Splitting for Generating Carbon Dioxide and Hydrogen for Synthetic Fuel Production
Background
The conversion of solar energy to fuels requires both water (H2O) and carbon dioxide (CO2) as feedstocks. These feedstocks provide the carbon and hydrogen atoms necessary to form hydrocarbons. By removing oxygen from one or both of these compounds, liquid hydrocarbon fuels can be produced. Water can be converted into hydrogen and oxygen...

Nano-Sized Boron-Doped Diamond-Enabled Electrodes for Water Treatment and Chemical Sensing
Background
Electrochemical sensing is a compact process used to detect chemicals in aqueous solutions (e.g., water, bodily fluids, foods). It can also be used to treat pollutants in drinking and industrial wastewaters. Electrochemical oxidation can generate hydroxyl radicals, which are effective in degrading organic contaminants in water, including...

Robotic Shake Table for Earthquake Research and Education
Shake tables provide a critical tool for simulating earthquake events and testing the response of structures to seismic forces. Simulated earthquake conditions can help civil engineers identify potential weaknesses in the design and suggest ways to improve a structure’s resilience. In a controlled laboratory setting, shake tables can also be...

Vibrational Wireless Underground Communication System
Wireless underground sensing networks (WUSNs) aim to provide real-time remote sensing of soil properties and monitoring of underground activities. Most subterranean animals have already mastered the use of vibrations for underground communication, localization of prey, and detection of predators. Humans, on the other hand, have yet to develop communication...

Methods and Systems for Ultra-trace Analysis of Environmental Waters
Many sites with ground and/or surface water pollution
have been identified across the United States. For site characterization,
exposure and risk assessment as well as remediation monitoring, it is important
to analyze the environment for toxic contaminants at trace levels. However, this
sensing is often expensive, especially when attempting...

SulfCo
Background
Recent research in the asphalt industry has focused on promoting sustainability through reducing mixing and compaction temperatures. Sulfur-extended asphalt has been studied extensively for this purpose because of the reduction in price of asphalt concrete that sulfur offers, as well as reducing the mixing and compaction temperatures. However,...

Design and Application of Form Factors for Sorbent Materials
Background
Many current air-capture designs feature flat air contactor surfaces with air flow predominantly tangential to those surfaces. In many cases, it may be advantageous to induce some turbulence across the sheet to enhance transport into the depth of the material. In general, it is advantageous to create surface roughness that is designed to...

CoolPaint
Background
Multifunctional coatings are typically made from nanoparticles of magnesium oxide (MgO) that have the ability to carbonate and serve as a permanent carbon-storage medium. The inorganic phase, consisting of MgO particles, is combined with an organic blend comprising an amine-terminated polymer. This organic component facilitates the capture...
