3D models for placing nanoparticles in the palm of your hand

Nanoparticles are super tiny―as small as one nanometer, or one billionth of a meter―and are of keen interest to materials scientists for their unique physical and chemical properties. They cannot be detected by the naked ...

Unexpected speed-dependent friction in graphene

Due to their low-friction properties, materials consisting of single atomic layers are of great interest for applications where the aim is to reduce friction—such as hard disks or moving components for satellites or space ...

Can gold mining be more sustainable?

In a review paper recently published in the journal Land Degradation and Development, Shrabya Timsina and Nora Hardy focused on the effects of surface gold mining in tropical regions, a growing environmental concern in recent ...

Diagnosing jaundice using tear fluids

Human tear fluids contain many proteins, metabolites, and other molecules whose concentrations change significantly with certain diseases. A research team has now developed a handy test kit for tears that can identify patients ...

New inexpensive and nontoxic method for creating benzene rings

Chemical syntheses in liquids and gases take place in three-dimensional space. Random collisions between molecules have to result in something new in an extremely short time. But there is another way: on a gold surface under ...

Single-cell analysis reveals heterogeneity in metal adsorption

Biosorption is the removal of contaminants from a sample by adsorbing them onto the surface of a biological material. It is expected to provide environmental and economic benefits compared with conventional separation techniques. ...
