Illustration of the integrated PEC device.

Researchers have created a smart device capable of producing large amounts of clean hydrogen. By concentrating sunlight, their device uses a smaller amount of the rare, costly materials that are required to produce hydrogen, yet it still maintains a high solar-to-fuel efficiency. Their research has been taken to the next scale with a pilot facility installed on the EPFL campus.

Scientists at EPFL’s Laboratory of Renewable Energy Science and Engineering (LRESE) came up with the idea of concentrating solar irradiation to produce a larger amount of hydrogen over a given area at a lower cost...

Surprising Quantum effect in Hard Disk Drive material


Researchers at Argonne have discovered a way to control the direction of electron spin in a cobalt-iron alloy, influencing its magnetic properties. The result could have implications for more powerful and energy-efficient materials for information storage.

Scientists have further explored a new effect that enhances their ability to control the direction of electron spin in certain materials. Their discovery may lead to more powerful and energy-efficient materials for information storage.

Sometimes scientific discoveries can be found along well-trodden paths. That proved the case for a cobalt-iron alloy material commonly found in hard disk drives. As reported in a recent issue of Physical Review Letters, researchers from the U.S...

Quantum Gas turns Supersolid

Several tens of thousands of particles spontaneously organize in a self-determined crystalline structure while sharing the same macroscopic wavefunction — hallmarks of supersolidity.

Researchers report on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.

Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring rather antithetic properties, has been long searched in superfluid helium...

3D printing of chalcogenide glass could enable low-cost manufacturing of complex optical components for telecom and sensing applications. For the first time, researchers have successfully 3D printed chalcogenide glass, a unique material used to make optical components that operate at mid-infrared wavelengths. The ability to 3D print this glass could make it possible to manufacture complex glass components and optical fibers for new types of low-cost sensors, telecommunications components and biomedical devices.
