Abstract: This invention relates to the low-cost manufacture of a tunable physical topographic pattern and more particularly to the manufacture of micro and nano scale hierarchical periodic wrinkle patterns that are generated upon compression of supported thin films. Disclosed herein is (i) a composite material with tunable hierarchical wrinkle patterns, wherein the composite material comprises a stretched and pre-patterned base layer and a thin film that is conformally attached to the pre-patterned surface of the base layer, (ii) a method of fabricating the pre-patterned base via pattern replication, and (iii) a method of fabricating tunable hierarchical wrinkle patterns, wherein the pattern can be deterministically switched across the hierarchical and non-hierarchical states via strain control.

Abstract: Disclosed herein are tiles, coatings, and related methods that provide both high cleanability and high slip resistance. The coating can be a surface coating with a unique chemical make-up. The surface coating can also have particles suspended within it. During a firing process, the coating and particles can settle in such a manner that the surface structure of the coating, and thus the surface structure of the tile, is both easy to clean and slip-resistant.

Abstract: A composite structural article includes a polymeric body having a first major surface and an opposing second major surface. The composite structure includes a continuous fiber element extending along and embedded within the lateral length of a rib element and/or an open mesh woven element embedded within and coplanar a textured surface of the first major surface or the opposing second major surface.

Abstract: A grain oriented electrical steel sheet reduces local exfoliation of insulating coating films and thus has excellent corrosion resistance and insulation properties. The grain oriented electrical steel sheet may be obtained by, assuming that a1 (?m) is a film thickness of the insulating coating at the floors of linear grooves and a2 (?m) is a film thickness of the insulating coating on a surface of the steel sheet at portions other than the linear grooves, controlling a1 and a2 to satisfy the following formulas (1) and (2): 0.3 ?m?a2?3.5 ?m??(1), and a1/a2?2.5??(2).

Abstract: A composite article having blast and ballistic resistance suitable for helmets, personal protection and hard armor applications comprises a high-strain hardening elastomeric layer and a layer of continuous yarns having a tenacity of 15 grams per dtex and a modulus of at least 500 grams per dtex or an oriented polyethylene sheet layer having a modulus ten times greater in one direction than in another direction.
