A research team from the Korea Institute of Energy Research has developed a technology that efficiently manages volatile organic compounds (VOCs) emitted from small-scale businesses and recycles them with lower energy consumption compared to existing methods. Notably, this technology can be applied to automotive painting businesses located in and around...

Sometimes cell phones die sooner than expected or electric vehicles don't have enough charge to reach their destination. The rechargeable lithium-ion (Li-ion) batteries in these and other devices typically last hours or days between charging. However, with repeated use, batteries degrade and need to be recharged more frequently....

Scientists at the Department of Energy's Oak Ridge National Laboratory and the University of Cincinnati achieved a breakthrough in understanding the vulnerability of microbes to the butanol they produce during fermentation of plant biomass. The discovery could pave the way for more efficient production of domestic fuels, chemicals and materials....

Solar cells convert sunlight into clean energy—but if the solar cells themselves are made of toxic materials, it almost defeats the purpose. That's where tin sulfide (SnS) comes in. SnS is an environmentally friendly, naturally abundant, and relatively inexpensive semiconductor material that is a promising candidate for use in solar...

Fossil-fuel plants are increasingly being forced to stop and start production in response to changes in output from renewables. In a new study, researchers developed a dynamic competitive benchmark that accounts for startup costs and other unit-level operating constraints. They apply their framework to Western Australia, a setting where rooftop...
