Clingy copper ions contribute to catalyst slowdown

Heavy-duty diesel trucks on the road today are equipped with aftertreatment systems that include selective catalytic reduction (SCR) technology using urea solution as a reducing agent to curtail harmful nitrogen oxide (NOx) ...

Magnetic nanoparticles pull valuable elements from water sources

A clever idea to use magnetic nanoparticles to capture valuable materials from brines has blossomed into industrial-scale pilot projects that could help make the U.S. a producer of critical minerals used in electronics and ...

Suitable spawning habitat awaits salmon

In a multi-stage effort to return migratory salmon to the Upper Columbia River so the fish may rekindle self-sustaining populations, scientists recently concluded that acres of suitable habitat await the salmon, should they ...

Preparing for climate's impact on renewables

Reducing the impacts of climate change will require substantial investments in renewable energy sources. But climate change itself could affect those renewable alternatives: changing yields for biomass crops, reduced streamflow ...

Cheaper carbon capture is on the way

As part of a marathon research effort to lower the cost of carbon capture, chemists have now demonstrated a method to seize carbon dioxide (CO2) that reduces costs by 19 percent compared to current commercial technology. ...
