The use of disposable plasticized medical gowns – both conventional and biodegradable – has surged since the onset of the COVID-19 pandemic. Landfills now brim with them.
“Blue” hydrogen – an energy source that involves a process for making hydrogen by using methane in natural gas – is being lauded by many as a clean, green energy to help reduce global warming. But Cor...
Researchers Use Novel Microreactor To Study Formation Of Methane Hydrate,An Icy Prison For Key Greenhouse Gas（图）
Researchers Novel Microreactor Methane Hydrate An Icy Prison Greenhouse Gas
2017/9/5
Researchers at the NYU Tandon School of Engineering are using a novel means of studying how methane and water form methane hydrate that allows them to examine discrete steps in the process faster and ...
For the first time scientists have looked at the net balance of the three major greenhouse gases—carbon dioxide, methane, and nitrous oxide—for every region of Earth’s landmasses. They found surprisin...
The discovery of a new form of microbial life that can consume the potent greenhouse gas methane has earned University of Queensland (UQ) researchers a place in the prestigious journal Nature.
Reuse of Recovered Waste Tail-Gas in a Full-Scale Furnace
Energy Recovery Carbon dioxide Furnace
2016/3/28
Recovery and reuse of waste energy to reduce fuel dependence on petroleum fuel, and to alleviate emissions of
contaminants is becoming an important policy for managing energy and the environment. In ...
Modified Chaplygin Gas and Solvable F-essence Cosmologies
Modified Chaplygin gas K-essence Fessence G-essence
