A metal-free organic framework for electrocatalytic production of ethylene from carbon dioxide
Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary c.....»»
Researchers investigate meridional deflection of global eddy propagation derived from tandem altimetry
Since the finding of their ubiquitous presence in the ocean decades ago, mesoscale eddies have been recognized as key contributors in transporting heat and substances. A common view on the meridional deflection of eddy propagation is poleward for cyc.....»»
How three tenacious reefs can help restore global oyster populations
Researchers at the University of Sydney have revealed how our oyster reefs can provide lessons on reef restoration projects. More than 85% of naturally occurring oyster reefs have been lost in recent decades due to disease, overharvesting, global war.....»»
