Patent number: 9353646Abstract: The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS). Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). SLIPS outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (<2.5°), quickly restore liquid-repellency after physical damage (within 0.1-1 s), resist ice, microorganisms and insects adhesion, and function at high pressures (up to at least 690 atm). Some exemplary application where SLIPS will be useful include energy-efficient fluid handling and transportation, optical sensing, medicine, and as self-cleaning, and anti-fouling materials operating in extreme environments.Type: GrantFiled: January 19, 2012Date of Patent: May 31, 2016Assignee: President and Fellows of Harvard CollegeInventors: Joanna Aizenberg, Michael Aizenberg, Sung Hoon Kang, Philseok Kim, Tak Sing Wong

Patent number: 9322953Abstract: An indefinite metamaterial where the surface or immediate subsurface region is roughened or disordered has improved coupling of electromagnetic waves incident on the medium. This also means that the amount of energy reflected by the material is reduced. Such a reduction in reflection may reduce the radar observability of a structure with a metamaterial surface, or increase the amount of energy coupled to a detector. An indefinite metamaterial has at least one of the components of the permittivity tensor that is different in sign from the other axes, and in a uniaxial indefinite material this differing axis is oriented perpendicular to the surface of the material. The disorder has scale dimensions of the order of a wavelength and may be random or periodic.Type: GrantFiled: May 18, 2011Date of Patent: April 26, 2016Assignee: PURDUE RESEARCH FOUNDATIONInventor: Evgueni E. Narimanov

Patent number: 9261140Abstract: A method involves the coating of a metallic substrate with a blasting medium through sandblasting or equivalent techniques. The blasting medium is preferably a powder made of silicon nitride (or other ceramic or engineering materials). The sandblasting process allows the silicon nitride powder to form a loosely packed layer on the substrate. With additional treatment via rolling and/or sliding action against a secondary body in the presence of a liquid lubricant, the loosely packed particle layer turns into a flattened surface matrix consisting of particle clusters and irregular cavities. The silicon nitride particles are spontaneously attached to the substrate surface without the use of an adhesive agent which subsequently leads to the formation of a surface matrix exhibiting a chaotic hybrid topography with zero tensile stress when subjected to rolling/sliding contact pressure. This cluster-cavity matrix can evolve continuously (thus dynamic) and is immune to debris indentation from dirty lubricants.Type: GrantFiled: December 30, 2009Date of Patent: February 16, 2016Inventor: Kenneth K. Chao

Patent number: 9169396Abstract: The invention relates to a method for the production of a web composed essentially of a granulate and a polymer. In order for the web to have good suction against the substrate after it has been laid on a floor, the interstices between the granulate particles are not allowed to be filled with the polymer. According to the invention, this is brought about in that the polymer is applied to the top side of the granulate. After the polymer melts, the polymer seeps down through the granulate. By means of targeted control or regulation, this sinking process is influenced before the polymer reaches the underside of the web. The invention also comprises a sensor and the product as such.Type: GrantFiled: January 19, 2011Date of Patent: October 27, 2015Assignees: TPS TechnoPartner Samtronic GmbHInventors: Hanns Joerg Mauk, Bernhard Voith, Bernd Fischer, Karl-Heinz Peter Scholz
