A novel mechanism for electron optics in two-dimensional solid-state systems opens up a route to engineering quantum-optical phenomena in a variety of materials.
A customizable smart window harnesses and manipulates solar power to save energy and cut costs.
MOFs and COFs are porous materials with a broad range of applications, such as gas storage, CO2 capture or drug delivery. Researchers have demonstrated that spray-drying is a suitable method for producing this kind of materials.
Using techniques similar to those they employed to develop laser-induced graphene, scientists turned adhesive tape into a silicon oxide film that replaces troublesome anodes in lithium metal batteries.
For the very first time, scientists have successfully imitated the functioning of brain neurons using semiconductor materials.
This phenomenon has a number of applications in magnetic sensors and magnetic reading heads, which, however, have not been reported in van der Waals heterostructures before.
Scientists have confirmed a long-standing theoretical prediction for high-temperature superconductors. Different states of matter make superconductivity possible. One of those theorized states of matter is called a pair density wave. The scientists confirmed pair density waves using advanced microscopic imaging techniques.
Vibrations of atoms in a crystal of the semiconductor gallium arsenide are impulsively shifted to a higher frequency by an optically excited electric current. The related change in the spatial distribution of charge between gallium and arsenic atoms acts back on their motions via electric interactions.
Researchers have discovered the highly selective separation of CO2 over nitrogen in composite membranes with ultrathin layers with selectivity governed by the molecularly thin interface formed between polymers.
Researchers have improved on the technique of local processing of composites based on nanoporous glass with addition of silver and copper; now, it is possible to predict with high accuracy the optical properties of a plasmonic component.
Researchers have developed a memory device using a two-dimensional layered-structure material, unlocking the possibility of commercializing the next-generation memory device that can be stably operated at a low power.
For a long time, something important has been regularly neglected in electronics: If you want to make electronic components smaller and smaller, you also need the right insulator materials.
Using sophisticated optical microscopy techniques, engineers demonstrate that sufficient strain in 2D material can yield single-photon emitters, key to quantum technologies and future photonic circuitry.
Researchers have developed a novel noninvasive approach called nano-radiomics that analyzes imaging data to assess changes in the tumor microenvironment that are not detected with conventional imaging methods.
In topological materials, electrons can display behaviour that is fundamentally different from that in 'conventional' matter, and the magnitude of many such 'exotic' phenomena is directly proportional to an entity known as the Chern number. New experiments establish for the first time that the theoretically predicted maximum Chern number can be reached in a real material.
Chameleons are famous for their color-changing abilities. Depending on their body temperature or mood, their nervous system directs skin tissue that contains nanocrystals to expand or contract, changing how the nanocrystals reflect light and turning the reptile's skin a rainbow of colors. Inspired by this, scientists have developed a way to stretch and strain liquid crystals to generate different colors.
A team of scientists have invented a new tool that can catch and straighten out molecule-sized tangles of polymers - whether made of protein or plastic. This tool, that works a bit like pulling a wad of thread through a needle hole, opens a new way to create custom materials that have never been made before.
Scientists studying in situ drying behavior of thin film coatings visualize interactions that could impact drug delivery technology.
Researchers have designed and fabricated an ultrasensitive plasmonic biosensor with the integration of atomically thin perovskite nanomaterials on metasurfaces. For that purpose, they used an atomically thin perovskite nanomaterial with high absorption rate, sandwiched between hexagonal boron nitride and graphene layers, which enables the precise tuning of the depth of the plasmonic resonance dip. This biosensor can reach an ultra-high plasmonic sensitivity for detecting small-molecule, low-concentration analytes.
Researchers have developed a method to 'print' a protective coating of copper oxide over the perovskite device. They have shown that only a 3-nanometre thick coating is sufficient to prevent any damage to the perovskite after depositing the transparent top electrode.
