Bio-Grafted Plastic Granules (BCPG)
Background Removal and immobilization of metal leachates from various compounds (industrial waste, mine tailings, waste engine oil, etc.) used in construction and the built environment is critical. Specifically, the use of mine tailing in construction of roadway base and sub-base could lead to leaching of metals to surface and ground water. In response...

WooplyMatt
Background According to the U.S. Environmental Protection Agency (EPA), volatile organic compounds (VOC) are compounds that have a high vapor pressure and low water solubility. Many VOCs are human-made chemicals that are used and produced in the manufacture of paints, pharmaceuticals, and refrigerants. These VOCs break down and harm the atmosphere,...

High-Efficiency Photocatalytic Formate Production from Carbon Dioxide
Background Greenhouse gases (GHGs) trap heat and lead to global warming and other severe effects of climate change. Carbon dioxide (CO2) is the main source of GHG, and its capture before entering the atmosphere is an important mitigation approach. Captured CO2 from point-emission sources or via direct air capture (DAC) can be geologically sequestered...

Electric Field Enhancement of Solar Thermochemical Fuel Production
Background Solar thermochemical carbon dioxide (CO2) splitting is a process where solar energy is used to split CO2 into carbon monoxide (CO) and oxygen (O2). Conventional solar thermochemical CO2 splitting involves a metal oxide being heated to its reduction temperature using concentrated thermal energy, which liberates O2. This process also exposes...

Coaxial Layered Fiber Spinning for Wind Turbine Blade Recycling
Background Plastic waste presents an acute environmental challenge to nearly all freshwater and marine ecosystems. The long degradation time of plastic requires effective methods of disposal to avoid adding additional plastic waste to aquatic environments. The end-of-life waste from wind turbine blades (WTBs) is also a pressing issue, as WTB waste...

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...
