Abstract: A free standing liquid membrane is disclosed that can selectively separate objects based on the kinetic energy value of the objects such that either an object having a first kinetic energy value can pass through the free standing liquid membrane while retaining the membrane and/or an object having a second kinetic energy value is prevented from passing through the membrane while retaining the membrane. Advantageously, the free standing liquid membrane can remain intact for seconds to hours with multiple objects passing through the membrane.

Abstract: A substrate with a switchable surface has been developed that can rapidly switch its surface character such as between two distinct liquid-repellent modes: (1) a superhydrophobic mode and (2) a slippery mode. Such surfaces have demonstrated adaptive liquid repellency and water harvesting capabilities.

Abstract: Synthetic brochosomes can be prepared by disposing a monolayer of first polymer microspheres on a substrate and forming a layer of metal on the monolayer of the first polymer microspheres. A monolayer of second polymer microspheres is then disposed on the layer of metal to form a template. The second polymer microspheres are smaller than the first polymer microspheres. A brochosome material is then electrodeposited on the template. The brochosome material is selected from the group consisting of a metal, a metal oxide, a polymer or a hybrid thereof. The first polymer microspheres and the second polymer microspheres are then removed to form a coating of synthetic brochosomes of the brochosome material on the substrate.

Abstract: An ostomy bag having a polymeric surface is prepared by forming a polyphenol layer on the surface, forming a silanization layer on the polyphenol layer and forming a lubricant layer entrenched over the silanization layer. The silanization layer is polymerized from a solution including: (i) a polymerizable silane or siloxane or combination thereof; (ii) a solvent; and (iii) an acid catalyst. The silanization layer comprises an array of silanes or siloxanes or a combination thereof each having ends anchored to the polyphenol layer and opposite ends extending away from the polyphenol layer.
