Presently, mechanistic paradigms in catalysis generally posit that the active species remains either homogeneous or heterogeneous throughout the reaction. In this work, we show that a prominent industrial process, palladium (Pd)–catalyzed vinyl acetate … Presently, mechanistic paradigms in catalysis generally posit that the active species remains either homogeneous or heterogeneous throughout the reaction.

For the first time, scientists have collected measurements close to a giant iceberg, giving an unprecedented window into the impact of meltwater on the surrounding Southern Ocean and ecosystem. The paper is published today (4 April 2025) in the journal Nature Geoscience. For the first time, scientists have collected measurements close to a giant iceberg, giving…

Sitting atop the land of the Muwekma Ohlone Tribe, located on the eastern hills of the Santa Cruz Mountains and about five miles southwest of Stanford University’s main campus, is one of its most beautiful classrooms: Jasper Ridge Biological Preserve (‘Ootchamin ‘Ooyakma). Since 1965, this site, a part of the School of Humanities and Sciences…

Members of the International Maritime Organization (IMO) are divided over whether to approve a carbon tax on international shipping, ahead of a meeting starting on Monday to finalize emissions-reduction measures. Members of the International Maritime Organization (IMO) are divided over whether to approve a carbon tax on international shipping, ahead of a meeting starting on Monday…

Five years ago, thanks to a federal program that distributes surplus military equipment to local police, Bridgeport acquired a heavily armored vehicle capable of withstanding a mine blast. Other places like Bristol, Hartford, New London, and Willimantic also got one. Five years ago, thanks to a federal program that distributes surplus military equipment to local police,…
