Acidification of slurry to reduce ammonia and methane emissions

Ammonia released into the environment is a major problem. Agriculture is considered the most prolific polluter—it is responsible for 95 percent of these emissions in Germany. The colorless, acrid gas is toxic in higher ...

Pressure-based control enables tunable singlet fission materials for efficient photoconversion

Applying hydrostatic pressure as an external stimulus, Tokyo Tech and Keio University researchers demonstrate a new way to regulate singlet fission (SF), a process in which two electrons are generated from a single photon, ...

An ancient mound of shells has been mined in the San Francisco Bay for 100 years—but the oyster's future is uncertain

For years now, if a commuter were to glance to the north side of the San Mateo Bridge, they might see a lonely barge, painted with the words "Lind Marine," floating a few hundred yards from the shoreline.

Scientists probe the source of stochastic occurrence of super-knock in engines running on hydrogen/methane fuels

In a study published in Combustion and Flame, researchers investigated the impact of non-thermal reaction chemistry on the propagation of combustion fronts for a H2-CH4 fuel mixture burning in air within a bounded domain, ...

Not waving, drowning: Why keeping warming under 1.5 C is a life-or-death matter for tidal marshes

It may not always be clear why global temperature rise must be kept below 1.5℃, compared to 2℃ or 3℃. Research published today in the journal Science shows this apparently small distinction will make all the difference ...
