How metals work together to weaken hardy nitrogen-nitrogen bonds

Nitrogen, an element that is essential for all living cells, makes up about 78 percent of Earth's atmosphere. However, most organisms cannot make use of this nitrogen until it is converted into ammonia. Until humans invented ...

New approach for solving protein structures from tiny crystals

Using x-rays to reveal the atomic-scale 3-D structures of proteins has led to countless advances in understanding how these molecules work in bacteria, viruses, plants, and humans—and has guided the development of precision ...

Origins of sulfur in rocks tells early oxygen story

(PhysOrg.com) -- Sedimentary rocks created more than 2.4 billion years ago sometimes have an unusual sulfur isotope composition thought to be caused by the action of ultra violet light on volcanically produced sulfur dioxide ...

Understanding the impact of defects on the properties of MoS2

Researchers at the Center for Integrated Nanostructure Physics have shown that defects in monolayer molybdenum disulfide (MoS2) exhibit electrical switching, providing new insights into the electrical properties of this material. ...
