Two-dimensional circuit with magnetic quasi-particles

Mon, 2018-01-22 21:41
Whether smart phone, computer or dialysis machine -- there is no electronic device without chips and their electronic components inside. The individual circuit elements are therefore often wired using three dimensional so called bridge constructions. Physicists are now working on a more efficient variation, where specific quasiparticles named magnons instead of electrons are being used. They have shown for the first time, in an initial model, that magnon current flow is possible in an integrated magnon circuit, in which case the components are only being connected two dimensionally.

New semiconductor processing technology developed

Mon, 2018-01-22 21:10
Extremely fine porous structures with tiny holes -- resembling a kind of sponge at nano level -- can be generated in semiconductors. This opens up new possibilities for the realization of tiny sensors or unusual optical and electronic components.

Making fuel cells for a fraction of the cost

Mon, 2018-01-22 19:43
Researchers now describe the development of an inexpensive, efficient catalyst material for a type of fuel cell called a polymer electrolyte membrane fuel cell, which turns the chemical energy of hydrogen into electricity and is among the most promising fuel cell types to power cars and electronics.

Virtual reality goes magnetic

Sat, 2018-01-20 05:34
The success of Pokémon GO made many people familiar with the concept of 'augmented reality': computer-generated perception blends into the real and virtual worlds. So far, these apps largely used optical methods for motion detection. Physicists have now developed an ultrathin electronic magnetic sensor that can be worn on skin. Just by interacting with magnetic fields, the device enables a touchless manipulation of virtual and physical objects.

'Programmable droplets' could enable high-volume biology experiments

Sat, 2018-01-20 05:33
Researchers have developed hardware that uses electric fields to move droplets of chemical or biological solutions around a surface, mixing them in ways that could be used to test thousands of reactions in parallel.

A nanostructured gate dielectric may have addressed the most significant obstacle to expanding the use of organic semiconductors for thin-film transistors. The structure, composed of a fluoropolymer layer followed by a nanolaminate made from two metal oxide materials, serves as gate dielectric and protects the organic semiconductor - which had previously been vulnerable to damage from the ambient environment.
