[Graphene] – Misalignments in encapsulated graphene lead to strong modification of electronic properties 23 February 2020

Researchers at the University of Antwerp report how higher-order periodic modulations called supermoiré caused by the encapsulation of graphene between hexagonal boron nitride affect the electronic and structural properties of graphene, as revealed in three recent independent experiments.

[Energy Storage] – Scientists learn more about the first hours of a lithium-ion battery’s life 23 February 2020

The first hours of a lithium-ion battery’s life largely determine just how well it will perform. In those moments, a set of molecules self-assembles into a structure inside the battery that will affect the battery for years to come.

[Nanoparticles] – Copper oxide sub-nanoparticle catalysts prove most superior 23 February 2020

Scientists at Tokyo Institute of Technology have shown that copper oxide particles on the sub-nanoscale are more powerful catalysts than those on the nanoscale. These subnanoparticles can also catalyze the oxidation reactions of aromatic hydrocarbons far more effectively than catalysts currently used in industry.

[Nanophotonics] – Silver sawtooth creates valley-coherent light for nanophotonics 23 February 2020

Scientists at the University of Groningen used a silver sawtooth nanoslit array to produce valley-coherent photoluminescence in two-dimensional tungsten disulfide flakes at room temperature.
Until now, this could only be achieved at very low temperatures. Coherent light can be used to store or transfer information in quantum electronics. This plasmon-exciton hybrid device is promising for use in integrated nanophotonics (light-based electronics).

[Nanoparticles] – Self-Cleaning Clothing- What Role do Nanoparticles Play? 23 February 2020

The use of nanoparticles to enhance clothing is not a new development. Starting in the mid-2000s, many garment manufacturers began integrating silver nanoparticles with antimicrobial qualities into their products. More recently, major advancements have been made in self-cleaning fabrics that make use of nanoparticles.

[Perovskites] -Perovskites reveal huge resettable single-photon response 23 February 2020

Despite the progress in perovskite device efficiencies, these systems are not fully understood, in particular the frequency- and power-dependence of their response to light. Yu-Hwa Lo and colleagues at the University of California in San Diego (UCSD) now report on systematic investigations of how these devices respond to light for frequencies varying over eight orders of magnitude and power ranging from millions to single photons.

[Nano-Medecine] – Drug release inside the cell 23 February 2020

The concept is based on the interaction of resonant semiconductor iron oxide Fe2O3 nanoparticles with light. Particles previously loaded with the antitumor drug are injected in vivo and further accumulate at the tumor areas. In order to release the drug non-invasively, the carrier particles have to be light-sensitive. For this purpose, the polymer containers (capsules) can be modified with iron oxide resonant semiconductor nanoparticles. When irradiated with light, they get heated and induce drug release.
