  • Reactant enrichment of nanoreactors boosts hydrogenation performance

    Reactant enrichment of nanoreactors boosts hydrogenation performance

    The picture shows mechanism of nanoreactor. The hollow structure of the Pt NPs@MnOx nanoreactor affords a confined space in which reactants enter via directional diffusion driven by the concentration gradient. Then, selective adsorption reduces the internal reactant concentrations, which would promote the in-diffusion of reactants consistently. After the reaction with abundant hydrogen atoms, the weak…

    The Future of Fully Homomorphic Encryption

    This sponsored article is brought to you by NYU Tandon School of Engineering. In our digital age, where information flows seamlessly through the vast network of the internet, the importance of encrypted data cannot be overstated. As we share, communicate, and store an increasing amount of sensitive information online, the need to safeguard it from…

  • New twist on optical tweezers

    New twist on optical tweezers

    Nov 01, 2023 (Nanowerk News) Optical tweezers manipulate tiny things like cells and nanoparticles using lasers. While they might sound like tractor beams from science fiction, the fact is their development garnered scientists a Nobel Prize in 2018. Scientists have now used supercomputers to make optical tweezers safer to use on living cells with applications…

  • Neutralizing electronic inhomogeneity in cleaved bulk MoS₂

    Neutralizing electronic inhomogeneity in cleaved bulk MoS₂

    The illustration shows the MoS2 lattice structure (green: Mo, yellow: S). The material after cleaving is shown in the forefront, the surface is jagged, and the measured surface electronic structure is inhomogeneous (colored map). In the back is the cleaved material after exposure to atomic hydrogen (represented by the white balls). The measured surface electronic…

    How hydrogen treatment makes MoS2 more reliable for various applications

    Nov 01, 2023 (Nanowerk News) Molybdenum disulphide (MoS2) is a highly versatile material that can function, for example, as a gas sensor or as a photocatalyst in green hydrogen production. Although the understanding of a material usually starts from investigating its bulk crystalline form, for MoS2 much more studies have been devoted to mono and…
