Abstract: Examples include microfluidic devices. Example microfluidic devices comprise a first microfluidic channel, a second microfluidic channel, and microfluidic output channel fluidly coupled to the first microfluidic channel and the second microfluidic channel via a fluid junction. The example device comprises a first fluid actuator disposed in the first microfluidic channel to actuate to thereby pump a first fluid into the microfluidic output channel, and the example device comprises a second fluid actuator disposed in the second microfluidic channel to actuate to pump a second fluid into the microfluidic output channel. The first fluid actuator and the second fluid actuator are to actuate to thereby pump a fluid mixture of the first fluid and the second fluid into the microfluidic output channel.

Abstract: A sample comprising a first substance and a second substance is modified by breaking down molecular bonds of the second substance of the sample to form a modified sample having altered surface enhanced luminescence (SEL) characteristics to reduce overlapping of SEL characteristics of the first substance in the second substance. Surface enhanced luminescence data resulting from excitation of the modified sample is collected. Characteristics of the first substance based upon the collected surface enhanced luminescence data are identified.

Abstract: A printhead having a number of single-dimensional memristor banks is described. The printhead includes a number of nozzles to deposit an amount of fluid onto a print medium. Each nozzle includes a firing chamber to hold the amount of fluid, an opening to dispense the amount of fluid onto the print medium, and an ejector to eject the amount of fluid through the opening. The printhead also includes a number of single-dimensional memristor banks. Each memristor bank includes a number of memristors arranged in a single dimension and a number of serially-connected de-multiplexers to selectively activate a target memristor of the memristor bank. The number of serially-connected de-multiplexers is equal to the number of memristors and an output of at least one de-multiplexer is an input into a subsequent de-multiplexer.

Abstract: According to examples, an apparatus may include a printhead assembly containing a housing supporting a printhead. The printhead may have nozzles that are to fire droplets of a functional agent onto a layer of build material particles along respective flight paths to form sections of a 3D object from the build material particles, an array of light emission devices to direct respective light beams in the respective flight paths, and an array of photon detectors to detect respective light beams directed from a light source of the array of light emission devices, the light emission devices and the photon detectors being supported on the housing. The apparatus may also include a controller to determine whether any of the nozzles is operating improperly based upon whether the photon detectors detected the light beams and to output an instruction regarding an improperly operating nozzle in response to a determination that the nozzle is operating improperly.
