Tuning properties of membrane and catalyst layers optimizes reactors for fuel cells and more
Ethylene is a chemical widely used as a feedstock for producing polymers and industrial chemicals. Oxidative coupling of methane (OCM) is a promising, energy-efficient way of creating ethylene from natural gas by reacting methane with oxygen. However.....»»
Crunch time for Phoebus before testing
Launching things into space is hard. Aside from the engines and software, orbital calculations and the launch pad, the tanks that hold the fuel are a masterful example of engineering in their own right. And ESA will soon be testing the next generatio.....»»
Deepfake videos during Russian invasion of Ukraine could undermine trust
A new study explores themes in Twitter discussions of deepfake videos related to the Russian invasion of Ukraine, highlighting the potential for real videos to be mistaken for deepfakes and for deepfakes to fuel conspiracy theories. John Twomey of Un.....»»
Nighttime rehearsal for Ariane 6 toward first flight
Yesterday, a team of CNES, ESA, Arianespace and ArianeGroup personnel at Europe's Spaceport in Kourou, French Guiana, completed a full-scale wet rehearsal of the new Ariane 6 rocket that was fueled and then drained of its fuel. The test lasted over 3.....»»
