Materials that change temperature in response to mechanical stress could make possible solid-state refrigerators that are not only more efficient than traditional vapor compression cooling technology, but environmentally-friendly replacements.
Poop could be a goldmine - literally. Surprisingly, treated solid waste contains gold, silver and other metals, as well as rare elements such as palladium and vanadium that are used in electronics and alloys. Now researchers are looking at identifying the metals that are getting flushed and how they can be recovered.
How do you take the sea of gases that makes up our atmosphere and convert that into liquid fuels? Or how do you remediate greenhouse gases and turn them into something usable for the chemical industry?
Construction crews may someday use a plant molecule called lignin in their asphalt and sealant mixtures to help roads and roofs hold up better under various weather conditions. It also could make them more environmentally friendly.
Adapting to climate change could have profound environmental repercussions, according to a new study. It reveals that adaptation measures have the potential to generate further pressures and threats for both local and global ecosystems.
Electric vehicles are cool, research shows. Literally. A new study adds more fuel to the already hot debate about whether electric vehicles are more environmentally friendly than conventional vehicles by uncovering two hidden benefits.
A new report raises a question vital for the future: what government policies are most effective at accelerating energy innovations? A study of the economic forces in energy and environment, some of which are different than other industries, can help answer this.
Plastic products advertised as biodegradable have recently emerged, but they sound almost too good to be true. Scientists have now found out that, at least for now, consumers have good reason to doubt these claims.
Using discarded electronic boards, researchers have developed a system for obtaining clean hydrogen that can be used as fuel. The researchers have already registered the patent of the process in Japan.
A means by which the removal of carbon dioxide from coal-fired power plants might one day be done far more efficiently and at far lower costs than today has been discovered by a team of researchers. By appending a diamine molecule to the sponge-like solid materials known as metal-organic-frameworks (MOFs), the researchers were able to more than triple the CO2-scrubbing capacity of the MOFs, while significantly reducing parasitic energy.
