  • ELECTROCATALYST HAVING QUASI-TWO-DIMENSIONAL METAL NANOSHEET HAVING TURING STRUCTURE MORPHOLOGY
    Publication number: 20240018673
    Abstract: The invention discloses an electrocatalyst includes a quasi-two-dimensional metal nanosheet having a thickness ranging between 4 nm and 12 nm. The quasi-two-dimensional metal nanosheet includes platinum (Pt), nickel (Ni), and niobium (Nb). The quasi-two-dimensional metal nanosheet has a Turing structure morphology including one or more of Turing stripes and Turing spots assembled by individual metal nanocrystals having different orientations via constrained orientation attachment.

  • Ultra-flat and low-friction metallic glass film and a method for preparing the same
    Patent number: 11873551
    Abstract: An ultraflat and ultralow-friction metallic glass thin film is fabricated. The metallic glass thin film is a binary alloy, wherein a content of one metal element of the binary alloy is between 45 atomic % and 64 atomic %. The metallic glass thin film has an atomically smooth surface with a surface roughness Ra less than 0.1 nm and a total height of profile Rt less than 0.15 nm; the friction coefficient is below 1×10?2. Due to the metallic glass thin film being treated by ion bombardment, the metallic glass thin film is thermally ultrastable.
