Understanding the global carbon cycle provides scientists with vital clues about the planet's habitability.
Silicon anodes are generally viewed as the next development in lithium-ion battery technology. Silicon's ability to absorb more charge translates to longer battery life and smaller batteries, if researchers can check the physical expansion of the silicon that comes with charging. Research from Drexel University and the Trinity College in Ireland, suggests that adding MXene ink to the silicon electrode-making process would do just that.
Electric vehicles running on fuel cells tout zero emissions and higher efficiency, but expensive platinum is holding them back from entering a larger market. A new method increases fuel cell electrode activity at least tenfold, using 90 percent less metal.
In the United States, the removal of dams now outpaces the construction of new ones -- with more than 1,400 dams decommissioned since the 1970s -- and a new study suggests that the ecosystem effects of dam removal can be predicted.
In a paper entitled 'Organic Electrosynthesis for Sustainable Chemical Manufacturing,' NYU Tandon Professor Miguel Modestino and NYU Tandon doctoral student Daniela Blanco review the challenges and opportunities facing the global chemical industry amid pressure to decrease carbon emissions.
Researchers have documented a group of tanner crabs vigorously feeding at a methane seep on the seafloor off British Columbia -- one of the first times a commercially harvested species has been seen using this energy source.
Fossil fuel combustion is the main contributor to black carbon collected at five sites around the Arctic, which has implications for global warming, according to a study by an international group of scientists that included a US team from Baylor University.
Total human carbon dioxide emissions could match those of Earth's last major greenhouse warming event in fewer than five generations, new research finds. A new study finds humans are pumping carbon dioxide into the atmosphere at a rate nine to 10 times higher than the greenhouse gas was emitted during the Paleocene-Eocene Thermal Maximum (PETM), a global warming event that occurred roughly 56 million years ago.
A Japanese research team at The University of Tokyo produced a 3-D cluster molecule based on palladium. First, they created a 'butterfly-shaped' Pd4 framewok, using an organosilicon compounds bearing the aromatic substitutents as both template and support for the palladium atoms. Then, using another template, they connected two butterfly-shaped Pd4 skeleton, via chlorine, into a Pd6 cluster based on edge-sharing tetrahedra. This strategy using organosilicons to design customized subnano-architectures may enable design of a range of functional materials and catalysts.
Significantly less than two degrees Celsius above pre-industrial times -- this is the temperature to which global warming should be limited, according to the Paris Climate Agreement. In a current study, a research team from the Karlsruhe Institute of Technology and the University of Edinburgh shows that previous efforts to reduce greenhouse gases through human land use are insufficient.
