Researchers build first 3D magnetic logic gate

(Phys.org) —The integrated circuits in virtually every computer today are built exclusively from transistors. But as researchers are constantly trying to improve the density of circuits on a chip, they are looking at alternative ...

Graphene-based sensor detects harmful air pollution in the home

Scientists from the University of Southampton, in partnership with the Japan Advanced Institute of Science and Technology (JAIST), have developed a graphene-based sensor and switch that can detect harmful air pollution in ...

Computers that mimic the function of the brain

Researchers are always searching for improved technologies, but the most efficient computer possible already exists. It can learn and adapt without needing to be programmed or updated. It has nearly limitless memory, is difficult ...

Bridging the nanoscale gap: A deep look inside atomic switches

A team of researchers from Tokyo Institute of Technology has gained unprecedented insight into the inner workings of an atomic switch. By investigating the composition of the tiny metal 'bridge' that forms inside the switch, ...

3-D magnetic interactions could lead to new forms of computing

A new form of magnetic interaction which pushes a formerly two-dimensional phenomenon into the third dimension could open up a host of exciting new possibilities for data storage and advanced computing, scientists say.

First observation of a square lattice of merons and antimerons

Scientists have, for the first time, observed a square lattice of merons and antimerons—tiny magnetic vortices and antivortices that form in a thin plate of the helical magnet Co8Zn9Mn3. By finely varying a magnetic field ...
