A method for creating a hydrophilic antimicrobial diamond coating on a silicon or glass surface includes providing a silicon or glass surface, creating a second surface by seeding a plurality of nanodiamond particles on the silicon or glass surface by microwave plasma chemical vapor deposition (MPCVD), and forming a silver nitrate and hydroxylamine solution. A third surface may be created by seeding a plurality of silver nanoparticles onto the second surface by spraying the silver nitrate and hydroxylamine solution onto the second surface and maintaining the silver nitrate and hydroxylamine solution on the second surface for a predetermined time. The third surface may then be exposed to an oxygen plasma treatment.

A method for designing new materials for superlubricity comprises developing, on a computational system, a computational supercell comprising x unit cells of a base material, each unit cell comprising y atoms of the base material. The computational system replaces randomly chosen z atoms of the base material with an impurity atom of an impurity material to form a candidate material. The computational system determines volumetric strain of the candidate material. In response to the volumetric strain exceeding a predetermined threshold, the computational system determines that the candidate material has superlubricity. The computational system displays the candidate material to a user if the candidate material has superlubricity.
