The sulfur cycle. In the soil, there are three forms of sulfur: sulfide gas, sulfide minerals and elemental sulfur, which must be oxidized into sulfate for plants to use.

Sulphur is found in many different compounds throughout the world -- not only in the atmosphere, but also in the oceans and on land. All these manifestations are connected in a cycle.

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 ...

Dr. Lang and colleagues present a new marine sulfur cycle model that incorporates the volatile organosulfur cycle to explain the global deposition of superheavy pyrite, i.e. pyrite isotopically ...

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.

It maintained over 80% of its initial capacity after 25,000 charge/discharge cycles. This far surpasses the durability of lithium-ion batteries, which degrade after approximately 1,000 cycles.

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 ...

A study into Lake Superior has revealed a 3 billion-year-old secret about planet Earth.. Researchers at the University of California, Santa Barbara, and University of Minnesota, Duluth, discovered ...

After more than a year of testing, the sulfur cathode remains stable and, as the team reported, its performance has not degraded in 4,000 charge-discharge cycles, which is equivalent to 10 years of ...
