Computation and theory

Better understanding of defect interaction could lead to better alloys

Engineers have identified two aspects of the interaction between a metal and its alloying material that can predict how a particular alloy will behave.

Researchers take nanomaterials down to the next level

Researchers have developed an artificial, layered crystal composed of the elements lanthanum, titanium, cobalt and oxygen in atom-thick sheets.

Copper impurities produce strongest ever silver

By simply adding a trace amount of copper, scientists have created the strongest ever silver without reducing its electrical conductivity.

Silver helps borophene grow to unprecedented lengths

Using a silver substrate and molecular-beam epitaxy , scientists were able to grow elongated, hexagon-shaped flakes of the 2D material borophene.

New model reveals role of hopping electrons in high-temperature superconductors

A new model suggests that high-temperature superconductivity in cuprates arises when electrons hop from atom-to-atom in a particular pattern.

Machine-learning algorithm can pick out just the right dielectric Lego piece

Engineers have harnessed machine learning to design dielectric metamaterials that absorb and emit specific frequencies of terahertz radiation.

Molybdenum helps produce better transparent coating for touchscreens

Researchers have found that doping indium oxide with molybdenum rather than tin doubles the conductivity of this transparent conductor.

Tiny material protrusions generate static electricity when rubbed together

A new model shows how rubbing two objects together produces static electricity by bending tiny protrusions on the surface of the objects.
