Abstract: A system is provided for generating a microfluidic channel. The system may include a co-flow generator having a delivery tube configured to provide a support liquid. The co-flow generator may include a coupling having an outlet configured to provide an epoxy resin. The delivery tube may be centrally positioned in the outlet of the coupling such that the delivery tube and the outlet together eject a co-flow of epoxy and support liquid into a tubular shell. The system may further include a conductive ring defining a hole through which the tubular shell extends. Heating the conductive ring causes or hastens curing of the epoxy resin to form a micro-channel defined by the cured epoxy around the support liquid.

Abstract: Embodiments of this disclosure relate to the multimedia processing field, and provide a video frame interpolation method, apparatus, and a device. In the video frame interpolation method in this disclosure, a first image at first time, a second image at second time, and sensor data captured by a dynamic vision sensor apparatus are obtained, and the sensor data includes dynamic event data between the first time and the second time. At least one target image is determined based on the first image, the second image, and the sensor data, where the at least one target image is an image corresponding to at least one target time between the first time and the second time. The dynamic event data is used to help compensate for motion information missing from existing image data. This implements accurate prediction of an intermediate image, and improves image prediction effect.

Abstract: A system contains a CO2 purifier and a CO2 electrolyzer. In operation, the CO2 purifier selectively captures CO2 from a gas stream and then releases purified CO2 as an output. The purified CO2 is then provided as an input to the cathode of the CO2 electrolyzer. The CO2 electrolyzer can electrochemically reduce the CO2 to a carbon-containing product (CCP) that may be stored, consumed, used to synthesize a valuable product, etc. The purifier may be an electrochemical cell that allows at least some non-CO2 inlet components to pass without being absorbed. Depending on the composition of the inlet stream, examples of non-absorbed components include water, nitrogen, carbon monoxide, oxygen, and sulfur-containing compounds.
