A team of physicists said they have finally experimentally documented quantum spin liquids, a long sought-after exotic state of matter. The work marks a big step toward being able to produce this elusive state on demand and to gain a novel understanding of its mysterious nature.
By trapping light into tiny crevices of gold, researchers have coaxed molecules to convert invisible infrared into visible light, creating new low-cost detectors for sensing.
Researchers have built a micro-device that uses vibrating molecules to transform invisible mid-infrared light into visible light. The breakthrough ushers in a new class of compact sensors for thermal imaging and chemical or biological analysis.
Scientists have developed a way to create a more complex magnetic moment arrangement in chromium triiodide, allowing this atomically thin material to store more information and to perhaps process information faster.
Researchers used electron energy loss spectroscopy to directly measure the coefficient of thermal expansion at grain boundaries in the polycrystalline material SrTiO3. The researchers identified differences in the coefficient of expansion depending on the grain boundary.
Researchers have developed a new photocatalyst made from an aerogel that could enable more efficient hydrogen production. The key is sophisticated pretreatment of the material.
Scientists have developed a new approach for observing mechanochemical reactions - where simple ingredients are ground up to make new chemical compounds and materials that can be used in anything from the pharmaceutical to the metallurgical, cement and mineral industries.
Researchers have developed tiny 'Janus balls' that show their colored side under a magnetic field. These microparticles could be useful in inks for anti-counterfeiting tags, which could be verified with an ordinary magnet.
An international team of scientists has unveiled a unique quantum-mechanical interaction between electrons and topological defects in layered materials that has only been observed in engineered atomic thin layers.
The concepts of metamaterials and metasurfaces have spawned massive novel applications in free-space optics. However, recent research also indicates that they possess prominent potential for tailoring the electromagnetic modes in optical waveguides. In a new review, researchers discuss recent advances of applying various meta-structures with diverse waveguide platforms to enhance the performance and expand functionalities for integrated photonic devices.
Scientists have discovered how a previously known form of resonator, made of two parallel mirrors, can be created and controlled in a much simpler way than previously realised.
