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) emissions from engine exhaust before they reach the tailpipe. SCRs rely on a catalyst to help chemically convert NOx gases into nitrogen, water, and small amounts of carbon dioxide.
The team’s findings could aid the design of catalysts that work better and last longer during the nitrogen oxide conversion process known as selective catalytic reduction.
As the world scrambles to head off the long-term impacts of climate change, much of the effort has gone toward replacing industrial processes that produce carbon dioxide.For instance, wind and solar generation have offset electricity from fossil fuel

Abstract:
Inspired by nature, researchers at Pacific Northwest National Laboratory (PNNL), along with collaborators from Washington State University, created a novel material capable of capturing light energy. This material provides a highly efficient artificial light-harvesting system with potential applications in photovoltaics and bioimaging.

The research provides a foundation for overcoming the difficult challenges involved in the creation of hierarchical functional organic-inorganic hybrid materials. Nature provides beautiful examples of hierarchically structured hybrid materials such as bones and teeth. These materials typically showcase a precise atomic arrangement that allow
