Much of western Europe has endured long stretches of hot weather and heat waves this summer. France recently experienced its hottest day on record and put 54 of its 96 departments under the highest heat alert.
A research team has developed a highly durable platinum-nickel (PtNi) hydrogen evolution catalyst that suppresses nickel (Ni) leaching through atomic ordering. Nickel leaching is a major cause of performance degradation in catalysts used for anion exchange membrane water electrolysis (AEMWE). The findings are published in the journal Carbon Energy.
As extreme weather intensifies, Reese Greenlee is testing the limits of 3D-printed concrete to create stronger, more accessible storm shelters for vulnerable communities.
With airlines and consumers increasingly concerned about carbon, nitrogen and hydrocarbon emissions, biofuels have emerged as a green alternative. Among these, those made from coconut oil are particularly attractive because they have fatty acid chain lengths similar to the hydrocarbon chain lengths required for jet fuel, suggesting they could make effective fuels with minimal processing.
The Fukushima nuclear disaster on March 11, 2011, triggered by a tsunami and leading to multiple reactor meltdowns, shook confidence in nuclear safety well beyond Japan. In Germany, it was a turning point: Chancellor Angela Merkel's government suspended nuclear power's earlier lifetime extensions and ultimately pursued a phase-out, with broad parliamentary support.
