E-waste recycling matter of national security: report

Recovering precious elements from e-waste is a security imperative for Europe that should be written into law, according to a report Monday that said it was "crucial" to ensure industry competitiveness and sustain tech-dependent ...

Observation of antichiral edge states in a circuit lattice

A modified Haldane lattice exhibits the intriguing phenomenon of antichiral edge states that propagate in the same direction on opposite edges and co-exist with bulk states. Using an electric circuit, researchers have successfully ...

New nanoscale device for spin technology

Researchers at Aalto University have developed a new device for spintronics. The results have been published in the journal Nature Communications, and mark a step towards the goal of using spintronics to make computer chips ...

Rules of resistance against transgene silencing

Clear rules for engineering transgenes that can be inserted and propagated over multiple generations of nematodes include ways to protect inserted genes from the organism's natural defenses against foreign DNA. Developed ...

Liquid metal ink liberates form

Today's electronic devices strive for new form factors—to make them foldable, stretchable, and deformable. To produce such devices that are highly stretchable or deformable, it is necessary to develop electrodes and circuit ...

Knotting semimetals in topological electrical circuits

Invented more than 15,000 years ago, knots represent one of the earliest technological breakthroughs at the dawn of human history that kick-started the subsequent rise of human civilisation. Even today, we are still relying ...
