Aryl radical formation by aryl halide bond cleavage by a N-heterocyclic carbene catalyst
Aryl halides with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a chemical reaction that generates a highly reactive aryl.....»»
New model refutes leading theory on how Earth"s continents formed
The formation of Earth's continents billions of years ago set the stage for life to thrive. But scientists disagree over how those land masses formed and if it was through geological processes we still see today......»»

Ice 0: Researchers discover a new mechanism for ice formation
Ice is far more complicated than most of us realize, with over 20 different varieties known to science, forming under various combinations of pressure and temperature. The kind we use to chill our drinks is known as ice I, and it's one of the few for.....»»
New research underscores the close relationship between Saharan dust and hurricane rainfall
Giant plumes of Sahara Desert dust that gust across the Atlantic can suppress hurricane formation over the ocean and affect weather in North America. But thick dust plumes can also lead to heavier rainfall—and potentially more destruction—from la.....»»
