Perovskite edges can be tuned for optoelectronic performance

Layered 2D material improves efficiency for solar cells and LEDs.

Researchers flip a magnetic memory cell with a light pulse at record speed

Electrical and computer engineering researchers have created a magnetic tunnel junction that can be switched by a pulse of light lasting one trillionth of a second - a new record.

Using nature to build nanomachines

Scientists have used electron cryomicroscopy to show that a small difference of only several amino acids can have a large impact on flagella function. The study gives new insight on the construction of synthetic nanomachines.

Conquering metal fatigue with laminated nanostructures

Novel laminated nanostructure gives steel bone-like resistance to fracturing under repeated stress.

New way to tune electronic energy levels may lead to valleytronic devices

Toward valleytronic devices for data storage or computer logic systems.

'photonic doping' makes class of metamaterials easier to fabricate

By carefully combining multiple structures, metamaterials can exhibit properties that don't naturally exist. Engineers now have a new, simpler way of making them, using a concept dubbed 'photonic doping'.

The prototype of a chemical computer detects a sphere (w/video)

It turns out that after an appropriate teaching procedure even a relatively simple chemical system can perform non-trivial operations. In their most recent computer simulations researchers have shown that correctly programmed chemical matrices of oscillating droplets can recognize the shape of a sphere with great accuracy.

New material helps record data with light

Researchers used metal-organic frameworks to generate quasiparticles - excitons, which were fully controllable and also helped to record information at room temperature.

Guiding light: 3-D metasurfaces with optical possibilities

The new metamaterials can be fabricated in multiple layers to form complex, three-dimensional meta-atoms that reflect more light than shiny gold surfaces, usually considered the ultimate in infrared reflectivity.
