Chicago’s West Side is air pollution hotspot

Chicago’s West Side is air pollution hotspot

In the new study, researchers developed a process to systematically identify areas of agreement and disagreement among three individual state-of-the-art air-quality datasets: satellite observations, a simulation developed at Northwestern and sensors from Microsoft Research’s Project Eclipse. Although one or two datasets identified multiple areas as NO2 hotspots, all three datasets consistently flagged Chicago’s West Side … Read more

Predicting the sustainability of a future hydrogen economy

Predicting the sustainability of a future hydrogen economy

As renewable energy sources like wind and solar ramp up, they can be used to sustainably generate hydrogen fuel. But implementing such a strategy on a large scale requires land and water dedicated to this purpose. Recent research in Nature Communications led by Carnegie’s Lorenzo Rosa and visiting scholar Davide Tonelli from ULB and UCLouvain … Read more
