I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Researchers discover new boron-lanthanide nanostructure” The family of boron-based nanostructures has a new member: metallo-borospherenes, hollow cages made from 18 boron atoms and three atoms of lanthanide elements. The discovery of carbon nanostructures like two-dimensional graphene and soccer ball-shaped buckyballs helped to launch a nanotechnology revolution. In recent years, researchers from Brown University and elsewhere…
“#New microscopy under ambient achieves less than 10 nm spatial resolution on surface potential measurement” Credit: ACS A new nanomaterials microscopy approach called Pulsed Force Kelvin Probe Force Microscopy (PF-KPFM), allows for less than 10 nanometer measurements of work function and surface potential in a single-pass AFM scan. The findings have been published in two…
“#Scientists home in on pairs of atoms that boost a catalyst’s activity” A study at SLAC and Stanford identified which pairs of atoms in a catalyst nanoparticle are most active in a reaction that breaks down a harmful exhaust gas in catalytic converters. The most active particles contained the biggest proportion of one particular atomic…
“#A new symmetry-broken parent state discovered in twisted bilayer graphene” The symmetry-breaking phase transition in magic-angle graphene. The four ‘flavours’ of Dirac electrons filling their energy levels are represented by four ‘liquids’ filling conical glasses. Credit: Weizmann Institute of Science In 2018 it was discovered that two layers of graphene twisted one with respect to…
“#Determining effective magnetic moment of multicore nanoparticles” Schema of multicore magnetic nanoparticle comprising N randomly oriented magnetic crystallites (gray spheres) each having a magnetic moment m_s. For clarity, the magnetic moments of only a few crystallites are shown. The effective magnetic moment of the multicore nanoparticle is given by the vectorial sum of the nanocrystallite…
“#Smallest cavity for light realized by graphene plasmons” Artistic illustration of the light compressed below the silver nanocubes randomly placed over the graphene-based heterostructure. Credit: Matteo Ceccanti Miniaturization has enabled technology like smartphones, health watches, medical probes and nano-satellites, all unthinkable a couple decades ago. Just imagine that in the course of 60 years, the…
