  • Patent number: 11585006
    Abstract: Disclosed herein are methods specifically tailored for facilitating the mitigation of cosmetic impressions associated with fingerprint impressions on surface(s) of articles of manufacture made from anodized substrates. To this end, such methods provide for removal of fingerprints by enzymatically functionalizing the surface(s) of the article of manufacture (e.g., a cosmetic coating thereof) to generate an enzymatically active surface and activating such enzymatically functionalized surface(s) to promote such fingerprint removal. Thus methods and articles of manufacture made in accordance with such methods provide improved end-use utility and functionality of many products for consumer electronic applications, automotive applications, building materials applications, and the like.

  • Patent number: 11499230
    Abstract: The disclosed methods and apparatus improve the fabrication of solid fibers and microstructures. In many embodiments, the fabrication is from gaseous, solid, semi-solid, liquid, critical, and supercritical mixtures using one or more low molar mass precursor(s), in combination with one or more high molar mass precursor(s). The methods and systems generally employ the thermal diffusion/Soret effect to concentrate the low molar mass precursor at a reaction zone, where the presence of the high molar mass precursor contributes to this concentration, and may also contribute to the reaction and insulate the reaction zone, thereby achieving higher fiber growth rates and/or reduced energy/heat expenditures together with reduced homogeneous nucleation. In some embodiments, the invention also relates to the permanent or semi-permanent recording and/or reading of information on or within fabricated fibers and microstructures.
