    Abstract: A device may include a substrate, a first fluid processing chip, a second fluid processing chip, a tapered channel, and a fluid actuator. The first fluid processing chip may be disposed on the substrate and may process a micro-volume of fluid. The second fluid processing chip may be disposed on the substrate and co-planar with the first fluid processing chip. The second fluid processing chip may process at least a portion of the micro-volume of fluid. The tapered channel may be disposed between the first and second fluid processing chips to transport the at least the portion of the micro-volume of fluid from the first fluid processing chip to the second fluid processing chip. The fluid actuator may be disposed proximate to the tapered channel and may control movement of the at least the portion of the micro-volume of fluid within the tapered channel.

    Abstract: A thermal contact device may include a thermal contact die embedded in a moldable material. The thermal contact die may include a number of resistors integrated into the thermal contact die, and a number of heater drivers integrated into the thermal contact die and electronically coupled to the resistors. The moldable material is coplanar with a thermal contact side of the thermal contact device. Further, the moldable material includes at least one gradient edge along a medium feed path.

    Abstract: In one example in accordance with the present disclosure, a fluidic ejection die is described. The die includes an array of nozzles. Each nozzle includes an ejection chamber, an opening, and a fluid actuator disposed within the ejection chamber. Each nozzle also includes an inlet passage to deliver fluid into the ejection chamber and an outlet passage to deliver fluid out of the ejection chamber. The fluidic ejection die also includes an array of channels divided into inlet channels and outlet channels. Each inlet channel is fluidly connected to a respective plurality of inlet passages and each outlet channel is fluidly connected to a respective plurality of outlet passages.

    Abstract: An example system includes a microfluidic cavity; a retaining feature within the microfluidic cavity, and a releasing feature. The retaining feature is to position capsules at a predetermined location in the microfluidic cavity. The capsules have a thermally degradable shell enclosing a material therein. The releasing feature is to selectively cause degradation of the shell to release the material into the microfluidic opening. The releasing feature is to generate heat to facilitate degradation of the shell. In some examples, the retaining feature is a physical barrier sized to prevent flow of the capsule and to allow flow of the released materials through the microfluidic cavity.
