(Phys.org)—Creating 3D visualizations of hydrogen atoms in proteins is especially challenging, often requiring their locations to be inferred from those of nearby carbon, nitrogen, oxygen or sulfur atoms stored in protein ...
(PhysOrg.com) -- On the macroscale, silicon is a brittle material that cannot be easily molded into a desired shape. But scientists have found that a piece of silicon just 3 nm long can be stretched to more than 20 times ...
(PhysOrg.com) -- Peering through a transmission electron microscope (TEM), researchers from Germany, Spain, and the UK have observed graphene sheets transforming into spherical fullerenes, better known as buckyballs, for ...
(PhysOrg.com) -- Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron ...

A small team of chemists from Nankai University, Nanjing Tech University and Shanxi University, all in China, working with a colleague from Universidad San Sebastián, in Chile, has, for the first time, created a fullerene-like ...
Polyethylene plastics—in particular, the ubiquitous plastic bag that blights the landscape—are notoriously hard to recycle. They're sturdy and difficult to break down, and if they're recycled at all, they're melted into ...

A team of researchers with members affiliated with several institutions in China has demonstrated real-space imaging of some of the most representative forms of hydrated protons. In their paper published in the journal Science, ...
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 ...
