Abstract:
This disclosure relates to a substrate treating method and a treatment liquid. The substrate treating method includes a treatment liquid supplying step, a solidified film forming step, and a sublimation step. In the treatment liquid supplying step, a treatment liquid is supplied to a substrate. The treatment liquid contains a sublimable substance, a solvent, and a surfactant. In the solidified film forming step, the solvent and the surfactant evaporate from the treatment liquid on the substrate. In the solidified film forming step, a solidified film containing the sublimable substance is formed on the substrate. In the sublimation step, the solidified film sublimates. The surfactant has an octanol-water partition coefficient LOGPow of −1 or more and 1 or less. Vapor pressure Pc of the surfactant at room temperature is 0.9 times or more and 3 times or less vapor pressure Pb of the solvent at room temperature.
Abstract:
Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.
Abstract:
Polypropylene (PP) superhydrophobic sheets and a fabrication method using a stream of polypropylene from plastic waste thereof are provided. Superhydrophobic PP sheets of varying thickness having a base layer and a top layer may be fabricated using recycled or waste polypropylene, where the fabrication process uses 20% of total plastic waste to prepare said sheets having contact angles ranging from 140 to 160 degrees. The polypropylene superhydrophobic sheets may impart protective water-repellent properties against the elements.

Abstract:
Reflectin proteins are proteins derived from cephalopods (certain species of squid) which have unusual optical properties. Disclosed herein are thin films of reflectin proteins which can be tuned to reflect infrared light. Advantageously, the films can be tuned dynamically over short time scales, to reflect at different wavelengths. Disclosed herein are novel infrared-reflective coatings, methods of making such coatings, and infrared-reflective objects such as textiles, building materials, and camouflage materials.
Abstract:
When a slurry in which a rare-earth-compound powder is dispersed is applied to sintered magnet bodies 1 and dried to apply the powder thereto, the sintered magnet bodies 1 are conveyed by a conveyer 2 and made to pass through the slurry 4 to apply the slurry to the sintered magnet bodies 1. Furthermore, a plurality of push-up members 51, which pass through insertion holes 22 provided in a conveyor belt 21, and protrude above the conveyor belt, are used to temporarily push up the sintered magnet bodies 1, and temporarily separate the conveyor belt 21 and the sintered magnet bodies 1. As a result, the slurry can be efficiently applied, even mass production can be suitably dealt with, and the slurry can be uniformly and reliably applied to the entire surface of each of the sintered magnet bodies.
Abstract:
A method of manufacturing a composite film, the method including: preparing a coating liquid including a resin and a filler and having a viscosity of from 0.1 Pa·s to 5.0 Pa·s: removing aggregates contained in the coating liquid by making the coating liquid pass through a filter having a minimum pore diameter that is larger than a maximum particle diameter of the aggregates; applying the coating liquid that has been subjected to the aggregate removal on one surface or both surfaces of a porous substrate, to form a coating layer; and solidifying the resin contained in the coating layer, to obtain a composite film including: the porous substrate; and a porous layer that is formed on one surface or both surfaces of the porous substrate and that contains the resin and the filler.
Abstract:
A method for producing a green body includes forming a layer which contains a powder of a ceramic on a substrate, applying at least one solidifying composition on at least a part of the layer, repeating forming the layer and applying at least one solidifying composition at least one time, removing the solvent or dispersing agent at least in part for forming a green body, and removing the powder which has not bonded and thereby exposing the green body. The solidifying composition contains a dissolved or liquid organometallic compound, which has at least one atom other than C, Si, H, O, or N bonded to at least one organic moiety, an organic binding agent, and a solvent or dispersing agent.
Abstract:
A composite structure includes a substrate, a first coating layer arranged on the substrate, and a second coating layer arranged on the first coating layer such that the first coating layer is between the substrate and the second coating layer. The composite structure may further include a third coating layer and an aggregate layer arranged on the second coating layer. A method of forming a composite structure includes applying a coating mixture by spray or by rolling, brushing or squeegeeing to a substrate, partially dissolving the substrate, thereby allowing the coating mixture to partially mix with the substrate to form a first coating layer on the substrate; and forming a second coating layer from the coating compound on the first coating layer.
Abstract:
A precursor sol of aluminum oxide contains a polycondensate formed by the hydrolysis of an aluminum alkoxide or an aluminum salt, a solvent, and an organic aluminum compound having a specific structure. An optical member is produced by a process including a step of immersing an aluminum oxide film in a hot water with a temperature of 60° C. to 100° C. to form a textured structure made of aluminum oxide crystals, the aluminum oxide film being formed by feeding the precursor sol of aluminum oxide onto a base.
