Slow orbital changes caused pulses in Earth's oxygen cycle 500 million years ago, which spurred explosions of animal life.

The Sturtian Snowball Earth glaciation (717~660 million years ago) represents the most severe icehouse climate in Earth's history. Geological evidence indicates that, during this glaciation, ice ...

A scientists has sulfur on her mind. The yellow element is a vital macronutrient, and she's trying to understand how it cycles through the environment. Specifically, she's curious about the sulfur ...

Lithium sulfur batteries are often touted as the next major chemistry for electric vehicle applications, if only their cycle life wasn’t so short. But that might be changing soon, as a group of ...

The hybrid sulfur cycle, integrating thermal and electrochemical processes, has emerged as a promising route for sustainable hydrogen production with minimal carbon emissions. At its core, the process ...

Estuaries and Coasts, Vol. 40, No. 5 (SEPTEMBER 2017), pp. 1346-1357 (12 pages) To evaluate the impact of invading seagrass on biogeochemical processes associated with sulftir cycles, we investigated ...

Nutrient cycles such as the carbon, nitrogen, phosphorous and sulfur cycles are critical processes that free up elements essential to life by recycling them through our water, air, and soil. Sulfur, ...

This is a preview. Log in through your library . Abstract ABSTRACT The time-dependent climate response to changing concentrations of greenhouse gases and sulfate aerosols is studied using a coupled ...

Chemists have discovered a completely unexpected shortcut in the global sulfur cycle. This process is determined by tiny organisms in the ocean's plankton. Sulphur is found in many different compounds ...

The biggest obstacle to mass production and use of sulfur-based batteries is durability. A good lithium-ion battery, like ...
