UV light-mediated difunctionalization of alkenes through an aroyl radical addition/1,4-/1,2-aryl shift has been described. The resulted aroyl radical from a photocleavage reaction added to acrylamide ...

Ozone pollution isn’t just a summer story anymore. In parts of northern China, high ozone levels are now appearing during ...

An improved catalytic system was developed for the Rh complex-catalyzed hydroxycarbonylation of alkenes using formic acid (HCOOH). Ligand screening revealed DPEphos, a bidentate phosphine ligand, to ...

The Avon Lake Public Library is home to one of only 19 Ozone Gardens in the United States, and the American Library Association has featured the local library in its national newsletter.

The advisory for Orange, Ulster, Dutchess, Sullivan, Putnam, Rockland and Westchester counties lasts from 11 a.m. to 11 p.m. Wednesday.

A team of chemists at the University of Cambridge has developed a powerful new method for adding single carbon atoms to molecules more easily, offering a simple one-step approach that could ...

Ozone forms when air pollutants react with sunlight, and Wednesday’s warm temperatures, sunny skies and thin layer of wildfire smoke provide the perfect ingredients. Pollution from cars and trucks ...

They say ozone levels are expected to reach the “Unhealthy for Sensitive Groups” category on Wednesday and Thursday along the coast from Kittery to Acadia National Park. Ozone air quality on ...

Ozone concentrations are forecast to reach the "Unhealthy for Sensitive Groups" (USG) rating along the coast from Kittery through Acadia National Park on both days. Inland areas—including Down East, ...

In addition to elevated ozone levels, a smoke plume from Canadian wildfires will cause hazy skies Wednesday. You can monitor the air quality in the state by clicking here . This article tagged under: ...

BACKGROUND: Previous research suggests that exposures to air pollution and nonoptimal temperatures are associated with a higher risk of acute myocardial infarction (AMI), but few studies examined the ...

In a recent letter (Nature, April 18), I ventured to counsel chemists to go back to the land — to study Faraday. Since then, in the Times (May 16), I have urged that Faraday’s great discovery ...
