Visualizing every step of on-surface cycloaddition reactions

By observing individual atoms as they rearrange themselves step by step, chemists at RIKEN have cast new light on the route by which halogenated aromatic molecules join together on a silver surface1. These insights promise ...

Creating and observing current vortices in 2-D materials

Researchers at the University of Chicago and the U.S. Department of Energy's Argonne National Laboratory have developed a new method to measure how photocurrents flow in a 2-D material—a result that could have implications ...

Taming electrons with bacteria parts

Electrons are tough to pin down in biology. Learning how to harness electrons is no fool's errand because, when electrons move, they are the electricity that powers life.

Unique organic light-emitting molecular emitters

A team including researchers from Osaka University has produced a new molecular emitter for organic light-emitting diodes (OLEDs). Using rational chemical design with U-shaped synthetic building blocks, the scientists were ...

The greenbacks in mobile phone mines

No-one who is economically active can afford to go without at least a mobile phone, and at the pace that electronic equipment is re-invented, it's only a matter of time before your 'latest' iPhone 11 ends up on a dump site.

Electronics

Electronics is a branch of science and technology that deals with the flow of electrons through nonmetallic conductors, mainly semiconductors such as silicon. It is distinct from electrical science and technology, which deal with the flow of electrons and other charge carriers through metal conductors such as copper. This distinction started around 1906 with the invention by Lee De Forest of the triode. Until 1950 this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers and vacuum tubes.

The study of semiconductor devices and related technology is considered a branch of physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering. This article focuses on engineering aspects of electronics.
