Abstract: Graphene printing is disclosed. A disclosed example graphene printing apparatus includes a gas source to cause a graphene precursor gas to flow across a surface of a substrate, and a localized heat source to locally heat portions of the surface to cause graphene to grow at the portions of the surface based on a printing pattern.

Abstract: According to an example, an apparatus may include a memory that may store instructions to cause a processor to generate, for each part to be fabricated in a build envelope of a 3D fabricating device, first level descriptions and second level descriptions for the part. The processor may determine, using the first level descriptions, whether there is an arrangement that results in the parts jointly fitting within the build envelope while providing certain thermal decoupling spaces between the parts. In response to a determination that the arrangement using the first level descriptions for the parts has not been determined, the processor may determine, using the second level descriptions, whether there is an arrangement that results in the parts jointly fitting within the build envelope while providing the certain thermal decoupling spaces.

Abstract: In an example, an air filter system includes an air filter and a thermally conductive particulate sensor (TCPS). The TCPS includes a temperature sensor to measure a first temperature of the TCPS at a first time, measure a second temperature of the TCPS at a second time, and provide the measured first temperature and the measured second temperature to a controller. The controller to determine an actual rate of temperature change based on the measured first temperature and the measured second temperature, compare the actual rate of temperature change to a target rate of temperature change, and provide a notification when a difference between the actual rate of temperature change and the target rate of temperature change is greater than an accumulation threshold indicative of a threshold amount of particulate accumulation on the TCPS.

Abstract: A surface enhanced Raman scattering (SERS) sensor may include a substrate, an electrically conductive layer having a first portion spaced from a second portion by a gap, an electrically resistive layer in contact with and extending between the first portion and the second portion of the electrically conductive layer to form an electrically resistive bridge across the gap that heats the nano fingers in response to electrical current flowing across the bridge from the first portion to the second portion and nano fingers extending upward from the bridge.

Abstract: According to an example, an apparatus may include a printhead to deliver a printing liquid from firing chambers through a plurality of bores arranged along a surface of the printhead. The apparatus may also include a cleaning system to apply a pressurized cleaning fluid onto the surface of the printhead while preventing application of the pressurized cleaning fluid into the firing chambers through the plurality of bores.

Abstract: According to an example, a three-dimensional (3D) printer may include a first delivery device to selectively deposit first liquid droplets onto a layer of build materials, in which the first liquid has a fusing radiation absorption property. The 3D printer may also include a fusing radiation generator to selectively emit fusing radiation at multiple ranges of wavelengths and at selected locations to selectively fuse the build materials and a controller to tune a range of wavelengths at which the fusing radiation generator is to emit fusing radiation based upon the fusing radiation absorbing property of the deposited first liquid, to determine the selected locations at which the fusing radiation at the tuned range of wavelengths is to be emitted, and to control the fusing radiation generator to selectively emit fusing radiation at the tuned range of wavelengths and onto the selected locations.

Abstract: An electronic device includes a marker with a pattern of marks encoding product information of the electronic device. The pattern includes first marks having a first material with a first isotopic ratio of an element, and second marks having a second material with a second isotopic ratio of the element different than the first isotopic ratio.

Abstract: In an example implementation, a substance detection device includes a chamber with chamber walls, a chamber top, and a chamber bottom. A substrate comprises imprinted nanostructures positioned within the chamber, and the substrate is coupled to the chamber walls to form the chamber bottom. An inert gas is sealed within the chamber.
