A method to form a protective overlay with wear resistant particles applied in well-defined patterns by applying wear resistant particles on a surface, bonding a part of the wear resistant particles with a binder preferably applied with a digital drop application head and removing the non-bonded wear resistant particles from the surface.

Methods for attachment and devices produced using such methods are disclosed. In certain examples, the method comprises disposing a capped nanomaterial on a substrate, disposing a die on the disposed capped nanomaterial, drying the disposed capped nanomaterial and the disposed die, and sintering the dried disposed die and the dried capped nanomaterial at a temperature of 300° C. or less to attach the die to the substrate. Devices produced using the methods are also described.

Methods and apparatus to identify additively manufactured parts are disclosed. An example apparatus includes a body, formed of layers layered substantially parallel to a base layer, composed of a first material having a first density, a first indicium embedded internally in the body as a void, and a second indicium on an external surface of the body, the second indicium aligning with the first indicium.

Aspects relate to patterned nanostructures having a feature size not including film thickness of below 5 microns. The patterned nanostructures are made up of nanoparticles having an average particle size of less than 100 nm. A nanoparticle composition, which, in some cases, includes a binder, is applied to a substrate. A patterned mold used in concert with electromagnetic radiation function to manipulate the nanoparticle composition in forming the patterned nanostructure. In some embodiments, the patterned mold nanoimprints a pattern onto the nanoparticle composition and the composition is cured through UV or thermal energy. Three-dimensional patterned nanostructures may be formed. A number of patterned nanostructure layers may be prepared and joined together. In some cases, a patterned nanostructure may be formed as a layer that is releasable from the substrate upon which it is initially formed. Such releasable layers may be arranged to form a three-dimensional patterned nanostructure for suitable applications.

Methods and systems for optical effects in pigments, inks, and on media. One aspect of this disclosure involves a pigment particle which includes a core, having a fluorescent material and having a spherical shape, and a shell surrounding the core; the shell includes a photochromic material which has a first optical property in a first light source and a second optical property in a second light source which includes a set of wavelengths not sufficiently present in the first light source. The second optical property attenuates an emitted radiation from the fluorescent material. Other aspects are also described.

A number of thin regions are formed in the drawn carbon nanotube film along the aligned direction by reducing density of carbon nanotubes in each of the plurality of thin regions. A variable-density carbon nanotube film is provided and includes a number of thin regions and at least one normal region having a density of carbon nanotubes greater than that of the thin regions. The at least one normal region includes a number of carbon nanotubes substantially aligned along an aligned direction. The thin regions are arranged in the form of at least one row extending along the aligned direction.
