One process has similar CO2 footprint to e-mobility
Technologies for the removal of carbon dioxide (CO2) from the atmosphere (direct air capture, or DAC for short) are already in use, but neither their actual benefits for climate protection nor their other environmental impact have yet to be investigated. A research team led by Kavya Madhu and ...
Just a single week’s worth of water from hydraulic fracturing in Texas’ Eagle Ford Shale has the potential to produce enough lithium for 300 electric vehicle batteries or 1.7 million smartphones
Anyone using a cellphone, laptop or electric vehicle depends on lithium. The element is in tremendous demand. And although the supply of lithium around the world is plentiful, getting access to it and extracting it remains a challenging and inefficient process. An interdisciplinary team of ...
An industrial process that currently consumes vast amounts of energy in petrochemical plants around the globe could be replaced by an alternative process so efficient that it requires no heating or elevated pressure. Niveen Khashab from KAUST's Advanced Membranes and Porous Materials Center and ...
Selective dissolution of elemental gold from multi-metal sources in organic solutions
“Urban mining”, the recycling of precious metals from electronic gadgets, becomes ever more important, although processes that are both efficient and environmentally benign are still scarce. An international team of scientists has now looked deeper into gold dissolution, in particular, how ...
Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke University study finds. "Human ...
Getting More From Biomass
Swedish-Finnish company Stora Enso is undergoing a renewable materials transformation. Previously focused on pulp and paper, the company is developing new, innovative products and services based on wood and other non-food competing feedstock. The goal – to replace non-renewable materials and use ...
Surface polarization in mixed media increases attraction among elements
Despite their name, rare earth elements actually aren't that rare. Abundant in mines around the world, rare earths are used in many high-tech products, including visual displays, batteries, super conductors, and computer hard drives. But while they aren't necessarily tricky to find, the elements ...
New efficient and inexpensive technologies being developed at Purdue University could allow the extraction of rare earth elements, critical components of many electronics and green products, from waste coal ash. This innovation could enable the U.S. to enter into the $4 billion rare earth element ...
Manchester scientists have revealed how arsenic molecules might be used to 'fish out' the most toxic elements from radioactive nuclear waste - a breakthrough that could make the decommissioning industry even safer and more effective. Elizabeth Wildman, a PhD student in the research group led by ...
Indiana University researchers have reported the first definitive evidence for a new molecular structure with potential applications to the safe storage of nuclear waste and reduction of chemicals that contaminate water and trigger large fish kills. The study provides experimental proof for the ...
