Abstract: This invention discloses a method for controlling nanoscopic wetting near or at a molecular scale for synthetic material applications. In particular this invention relates to a method for preparing a monolayer or thin film with a patterned nanoscopic wetting surface using a ‘sitting’ phase of polymerizable amphiphile, wherein hydrophobic alkyl chains of the amphiphile extend along the supporting surface and the amphiphile molecules align side-to-side, effectively forming a repeating cross-section of bilayer with alternating hydrophilic and hydrophobic stripes of a ˜6 nm pitch tunable based on the chain length of the amphiphile. Products prepared according to the methods disclosed herein are within the scope of this invention. In some embodiments, monolayers or thin films so prepared are transferable.

Abstract: A metallic stamp and die for the craft industry comprises a predetermined acid-etched design on a surface of a metallic plate. A first layer of a metallic paint is applied over the front and back surfaces of the metallic stamp and die. A second layer of a rubber paint is applied over the metallic paint. The metallic paint facilitates bonding of the rubber paint to the metallic plate and increases the life of the coating of the rubber paint. The rubber paint is configured to absorb and store an ink and facilitate transfer of the ink to one or more substrates, thus enabling stamping of the design on the substrate. The metallic die can be configured for a plurality of uses, such as embossing, cutting, heat-foiling, stamping, scoring, and inserting patterns or designs in a plurality of substrates.

Abstract: A painting target surface of a resin bumper is painted by discharging a paint mist from a spray gun toward the painting target surface with a charged conductor arranged in contact with an opposite side to the painting target surface. The paint mist is uncharged or is charged with electric charges having an opposite polarity to that of the conductor and at a potential having a lower absolute value than that of the conductor.

The coating formation method of the present invention includes a liquid agent applying step of applying a liquid agent containing one or more selected from water, polyols and oils that are in a liquid form at 20° C., and an electrostatic spraying step of electrostatically spraying a composition directly on skin to form a coating. The liquid agent applying step and the electrostatic spraying step are performed in this order or in a reversed order. The composition includes a component (a) and a component (b) below: (a) one or more volatile substances selected from the group consisting of water, alcohols, and ketones, and (b) a polymer having a coating formation ability.

Abstract: Methods of enhancing the anti-virus capabilities of surfaces directly contacted by humans. The methods include applying a hydrophobic coating material to a surface of an article to form a hydrophobic surface coating overlying the surface such that the hydrophobic surface coating defines a hydrophobic outer surface of the article. The hydrophobic outer surface is more hydrophobic than the surface of the article, and a liquid that contains suspended viruses and is deposited on the hydrophobic outer surface exhibits a contact angle relative to the hydrophobic outer surface that is greater than a contact angle of the liquid if directly deposited on the surface of the article, and the hydrophobic outer surface thereby increases inactivation of the viruses suspended in the liquid as compared to the surface of the article to which the hydrophobic coating material was applied.

Abstract: The invention relates to a coating method for coating a component surface (4) with a coating agent, in particular for painting a motor vehicle body component with a paint, having the following steps: ⋅ emitting a spray jet (1) of the coating agent onto the component surface (4) of the component to be coated by means of an atomizer (2), said spray jet (1) having a main axis (5) and having an asymmetry with respect to the main axis (5) such that the spray jet (1) generates a spray pattern with a corresponding asymmetry on the component surface (4), and ⋅ at least partially compensating for the asymmetry of the spray jet (1) such that the asymmetry of the resulting spray pattern on the component surface (4) is reduced. The invention further relates to a corresponding coating device.

Abstract: A laser-assisted microfluidics manufacturing process has been developed for the fabrication of additively manufactured structures. Roll-to-roll manufacturing is enhanced by the use of a laser-assisted electrospray printhead positioned above the flexible substrate. The laser electrospray printhead sprays microdroplets containing nanoparticles onto the substrate to form both thin-film and structural layers. As the substrate moves, the nanoparticles are sintered using a laser beam directed by the laser electrospray printhead onto the substrate.
