A method includes: sandwiching a plastic layer between a glass substrate and a metal plate made of an iron-nickel alloy and joining the metal plate to the glass substrate with the plastic layer in between; forming a mask portion including a plurality of mask holes from the metal plate; joining a surface of the mask portion that is opposite to a surface of the mask portion that is in contact with the plastic layer to a mask frame, which has a higher rigidity than the mask portion and is in a shape of a frame surrounding the mask holes of the mask portion; and peeling off the plastic layer and the glass substrate from the mask portion.

The purpose of the present invention is to provide a coated metal mold having superior durability and adhesion resistance over a usage range from cold to warm/hot; and a method for manufacturing the coated metal mold. The coated metal mold is characterized by having a hard coating on a surface, wherein the hard coating includes an A layer formed from a nitride and having a film thickness not smaller than 5 μm, and a B layer formed of a diamond-like carbon coating, the B layer is disposed closer to the outer surface side than the A layer, the surface of the B layer has an arithmetic mean roughness Ra≤0.2 μm, a maximum height Rz≤2.0 μm, and a skewness Rsk<0.

In a method for coating on a surface of a medical PEEK material with titanium to have a microporous structure, titanium is coated on a surface of polyether ether ketone (PEEK) via magnetron sputtering. The surface of the titanium coated on the surface of PEEK is polished via an electromagnetic polishing apparatus. A thin-film with titanium dioxide (TiO.sub.2) having a microporous structure is formed on the polished surface of the titanium via an anodic oxidation treatment.

A piston ring that is pre-treated by grit blasting to a defined roughness, followed by PVD coating with a metal nitride to a thickness of at least 10 μm, leaving peaks and valleys in the coated piston ring. The coated piston ring is then lapped to remove the peaks without penetrating the coating, so that valleys and plateaus remain in the coated surface. The resulting piston ring exhibits superior coating retention due to the increased surface area created by the grit blasting, and yet also superior performance, as the cavities remaining increase the porosity of the coating and thus enhance the lubrication of the ring.

An inorganic paint pigment may include a fluid matrix, and paint flakes carried within the fluid matrix. Each paint flake may include a common aluminum layer having a first major surface and a second major surface opposing the first major surface, a first plasmonic aluminum reflector layer carried by the first major surface, and a second plasmonic aluminum reflector layer carried by the second major surface.

A nano scale robotic system for single cell DNA sequencing of a strand of DNA positioned on a slide utilizes an atomic force microscope (AFM) having an end effector in the form of a cantilever with a tip. The AFM causes its cantilever tip to scan over the base pairs of the DNA strand. A pair of spaced-apart electrodes at the tip makes contact with opposite sides of the DNA strand and the current between bases of the DNA strand is measured by a current measurement system connected to the electrodes. An artificial intelligence-based data analytic system determines the DNA sequence based on the current from the current measuring system. The AFM tip is guided over the DNA strand by comparing compressed desired intensity local scan images and compressed actual intensity local scan images and using the difference to control the location of the tip.

A metallic sheet with deposited structured images and method for manufacture (MSDIMM) that includes a substrate, at least one structural feature, and a metal layer. The structural feature is at least one cavity on the substrate's upper surface, or at least one material object that extends outward from the substrate's upper surface. The metal layer is deposited, either by sputtering or atomic deposition, onto the substrate's upper surface, and, as the metal layer is deposited, the metal layer interfaces with and follows the dimensions of the structural feature(s), thereby creating a visible image at the location(s) of the structural feature(s). The visible image can be any image, and is preferably either an artistic image, a textual image, or an authentication image. The MDSIMM can be used for a variety of purposes, and is especially effective as a form of exonumia or currency.

An alpha-alumina coated turbocharger turbine wheel includes a hub portion, a plurality of blades disposed about the hub portion, each blade of the plurality of blades having a leading edge and a trailing edge, a centerline passing axially through the hub portion, and a back-side wall defined radially between the leading edge of each blade of the plurality of blades and the centerline. The turbocharger turbine wheel is made of a metal alloy and a surface coating layer of alpha-alumina. The surface coating layer of alpha-alumina may be disposed only on the hub portion, the plurality of blades, and a radially-outer portion of the back-side wall. The radially-outer portion is defined between a radial distance from the centerline and the leading edge of each blade of the plurality of blades. Alternatively, the surface coating layer of alpha-alumina may be disposed on the hub portion, the plurality of blades, and an entirety of the back-side wall.

A method for manufacturing a wavelength conversion member, includes: providing a wavelength conversion layer having a phosphor-containing portion and a light reflecting portion surrounding the phosphor-containing portion, and the wavelength conversion layer having an upper surface, a bottom surface and at least one side surface; forming a light-blocking film on the upper surface of the wavelength conversion layer; and removing a part of the light-blocking film by laser processing to expose at least a part of the phosphor-containing portion from the light-blocking film.
