  • Patent number: 11186731
    Abstract: The present disclosure describes a strategy to create self-healing, slippery self-lubricating polymers. Lubricating liquids with affinities to polymers can be utilized to get absorbed within the polymer and form a lubricant layer (of the lubricating liquid) on the polymer. The lubricant layer can repel a wide range of materials, including simple and complex fluids (water, hydrocarbons, crude oil and bodily fluids), restore liquid-repellency after physical damage, and resist ice, microorganisms and insects adhesion. Some exemplary applications where self-lubricating polymers will be useful include energy-efficient, friction-reduction fluid handling and transportation, medical devices, anti-icing, optical sensing, and as self-cleaning, and anti-fouling materials operating in extreme environments.

  • Publication number: 20140081012
    Abstract: Pharmaceutical, chemical and biological agents containing a reversible disulfide linker are described. These agents can also be covalently bound or contained in delivery vehicles for delivering the agents to desired targets or areas. Also described are delivery vehicles which contain an agent having a reversible disulfide linker and to vehicles that are covalently linked to the agent containing a reversible disulfide linker. The modifications described herein can modify properties of the agents and vehicles, thereby providing desired solubility, stability, hydrophobicity and targeting while the reversibility of the linker can leave the agent to which it is attached free from residual chemical groups after being reduced.

  • Patent number: 8375539
    Abstract: A method of manufacturing a low capacitance density, high voltage MIM capacitor and the high density MIM capacitor. The method includes depositing a plurality of plates and a plurality of dielectric layers interleaved with one another. The method further includes etching a portion of an uppermost plate of the plurality of plates while protecting other portions of the uppermost plate. The protected other portions of the uppermost plate forms a top plate of a first metal-insulator-metal (MIM) capacitor and the etching exposes a top plate of a second MIM capacitor.
