Study examines how clean air act affects municipal bond market

Credit: Unsplash/CC0 Public Domain Research has studied the effects of climate risk on financial markets, but few studies have addressed the effect of environmental policy on those markets. A new study examined whether federal policy aimed at mitigating local air pollution—specifically, the Clean Air Act—affected the municipal bond market from 2005 to 2019. The study […]

Buildings: The unbreakable bond

ORNL researchers produced self-healable and highly adhesive elastomers, proving they self-repair in ambient conditions and underwater.

Elastomers, commonly used […]

New type of ultra-strong chemical bond discovered

Scientists have recently discovered a totally new type of chemical bond — and it’s way stronger than it has any right to be. The new type of bond shows that the divide between powerful covalent bonds, which bind molecules together, and weak hydrogen bonds, which form between molecules and can be broken by something as […]

Researchers discover C-H bond activation reactions at low temperature by photo-induced means
