Billions of tiny particles packed into rechargeable lithium-ion battery electrodes are responsible for storing charge and making it available when it’s needed to do work. X-ray movies of this process show the particles absorbing and releasing lithium ions as the battery charges and discharges. Now, in an important step forward, researchers have used a type […]

As candidates for high-density data storage and quantum computation, magnetic transition metal complexes have attracted extensive attention. It has been established that the atomic surroundings of the magnetic ions play a significant role and govern the magnetism of these magnetic complexes. One feature in particular, magnetic anisotropy, which describes the preferential orientation of the magnetic […]

Scientists have successfully demonstrated that autonomous methods can discover new materials. The artificial intelligence (AI)-driven technique led to the discovery of three new nanostructures, including a first-of-its-kind nanoscale “ladder.” The newly discovered structures were formed by a process called self-assembly, in which a material’s molecules organize themselves into unique patterns. Scientists at Brookhaven’s Center for […]

Light emission from emitters is a valuable piece of information in a variety of sensing and detection techniques, capable of labeling physical and biological processes which occur in the proximity of the emitter. Furthermore, quantum technologies are currently exploiting the statistics of single-emitters light emission aiming at turning particular emitters into fundamental units to sustain […]

The Nobel Prize in Chemistry 2016 was awarded to Jean-Pierre Sauvage, Fraser Stoddart and Ben Feringa “for the design and synthesis of molecular machines”. Molecular machines are made by one or a few molecules linked together, comprising several hundred atoms. If a molecule can use an energy input to perform a mechanical movement (output) it […]

Graphene is a diamagnetic material, this is, unable of becoming magnetic. However, a triangular piece of graphene is predicted to be magnetic. This apparent contradiction is a consequence of “magic” shapes in the structure of graphene flakes, which force electrons to “spin” more easily in one direction. Triangulene is a triangular graphene flake, which possesses […]

When two photons with the same energy interact with a nonlinear material, they “combine” and generate a new photon with twice the energy of the initial photons. More precisely, two photons at the fundamental frequency are absorbed by a plasmonic structure to emit one photon at the second-harmonic frequency. This is called second-harmonic generation. Second-harmonic […]
