  • Patent number: 10271387
    Abstract: The present invention relates to a microwave interactive susceptor structure for the microwave heating of food products. In one aspect, the invention relates to a duplex design for the microwave interactive structure on cellulose-based substrates. In another aspect, the invention relates to a method of patterning the duplex microwave interactive structure on the substrates using a printing press with or without an alignment function.
    Type: Grant

  • Patent number: 10088751
    Abstract: The present disclosure discloses a method of fabrication of free standing open pore membranes with uniform pore size and shape and ordered pore distribution, and its use for synthesis of nanoparticle patterns. The method includes applying a photoresist layer to the top surface of a substrate, heating the photoresist layer for a period of time, and exposing the photoresist layer to a dose of ultraviolet radiation through a mask having a predetermined pattern. The dose of ultraviolet radiation is controlled in intensity and time and the photoresist layer is exposed such that a top portion of the photoresist layer through which the dose of ultraviolet radiation enters the photoresist layer undergoes greater cross linking than a bottom portion of the photoresist layer immediately adjacent to the top surface of the substrate such that a cross linking gradient develops through a thickness of the photoresist layer.

  • Patent number: 9442375
    Abstract: Disclosed herein is a substrate having a surface modified to impart multi-scale roughness, thereby providing superhydrophobic and/or superoleophobic properties. The surface comprises a pattern of microscale pillars topped by a plurality of nanoparticles having a re-entrant convex shape. The area fraction of the surface is also selected to provide the desired superoleophobic properties. Also disclosed herein is a process for creating the modified surface comprising photolithography, optionally followed by vapor deposition. The substrates may be formed into useful articles or applied to pre-formed articles.
