High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magneti ...

Be it magnets or superconductors: materials are known for their various properties. However, these properties may change spontaneously under extreme conditions. Researchers at the Technische Unive ...

EPFL researchers have discovered that Vanadium Dioxide (VO2), a compound used in electronics, is capable of “remembering” the entire history of previous external stimuli. This is the first materia ...

This view into processes that take place within so-​called artificial spin ice could play an important role in the development of novel high-​performance computers. When water freezes to form ice ...

Prussian blue analogs (PBAs) are promising cathode materials for sodium-ion batteries (SIBs) due to their low-cost, similar energy density comparable with that of LiFePO4 in lithium-ion batteries, and long cycle life. Nevertheless, crystal water (≈10 wt%) in PBAs from aqueous synthesis environments can bring significant side effects in real SIBs, especially for calendar life and high temperature storage performance. Therefore, it is of great importance to eliminate crystal water in PBAs for fu...

The development of highly secure but simple and inexpensive encryption technology for the prevention of data leaks and forgeries is decidedly challenging. In the journal Angewandte Chemie, a resea ...

Modifying surface and boundary features lets researchers control how a 2D model system transitions from a fluid to a crystalline phase.

Cornell-Forscher haben einen neuen Weg gefunden, die Torsionssteifigkeit der DNA zu messen - wie viel Widerstand die Helix bietet, wenn sie verdreht wird - eine Information, die möglicherweise Auf ...

Thin films of molybdenum and sulfur belong to a class of materials that can be considered for use as photocatalysts. Inexpensive catalysts such as these are needed to produce hydrogen as a fuel us ...

Date Time New Insight into Nonlinear Optical Resonators Unlocks Door to Numerous Potential Applications Optical resonators, which circulate and confine light (for instance in lasers), are currently used in a variety of applications of all sizes-from pinpoint light sources smaller than the width of a human hair to kilometer-scale sensing devices such as the Laser Interferometer Gravitational-wave Observatory (LIGO) experiment that detects gravitational waves. Devices known as optical parametric ...
