Widely tuneable terahertz lasers boost photo-induced superconductivity in K3C60      (via sciencedaily.com)     Original source 

Researchers have long been exploring the effect of using tailored laser drives to manipulate the properties of quantum materials away from equilibrium. One of the most striking demonstrations of these physics has been in unconventional superconductors, where signatures of enhanced electronic coherences and super-transport have been documented in the resulting non-equilibrium states. However, these phenomena have not yet been systematically studied or optimized, primarily due to the complexity of the experiments. Technological applications are therefore still far removed from reality. In a recent experiment, this same group of researchers discovered a far more efficient way to create a previously observed metastable, superconducting-like state in K3C60 using laser light.

Enlightening insects: Morpho butterfly nanostructure inspires technology for bright, balanced lighting      (via sciencedaily.com)     Original source 

Researchers developed a nanostructured light diffuser that provides balanced lighting by diffracting blue and red light, and can be cleaned by simple rinsing with water. The diffuser consists of cheap materials and can be shaped with common tools. A protective glass coating maintains the diffuser's optical performance yet adds durability. This work might improve the visual performance of everyday lighting displays.

Bringing out the color in zinc      (via sciencedaily.com)     Original source 

Researchers have synthesized a zinc complex based on two zinc centers that absorbs visible light. They demonstrated that this capability depends on the proximity of the zinc ions, where the complex responds to visible light when the zinc atoms are closer. This new property is expected to expand the utility of zinc, which already offers advantages including biological relevance, cost effectiveness, and low toxicity.

Groundbreaking study shows defects spreading through diamond faster than the speed of sound      (via sciencedaily.com)     Original source 

Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what give metals their strength and workability, but they can also make materials fail catastrophically ­– which is what happens every time you pop the pull tab on a can of soda. The fact that they can travel so fast gives scientists a new appreciation of the unusual types of damage they might do to a broad range of materials in extreme conditions.
