Abstract: Embodiments of this application provide a method for annotating video data performed by a computer device. The method includes: displaying target video data in a video application; displaying annotated media data in the video application in response to a trigger operation performed on a progress time point annotation function in the video application, the annotated media data being media data associated with a current progress time point, the current progress time point being a progress time point corresponding to the trigger operation to which the target video data is played; and sharing the annotated media data with another user in response to a confirmation operation performed on the annotated media data, the annotated media data enabling the second user to perform a progress jump on the target video data based on the current progress time point. Through this application, efficiency of video progress positioning can be improved.

Abstract: A method of selective deposition that includes disposing in a deposition chamber a patterned substrate of side-by-side areas of metal and dielectric. The deposition chamber is connected to a bubbler that contains an N-heterocyclic carbenes (NHC) precursor. By heating the bubbler, gaseous free NHC is generated which is pulsed into the deposition chamber, where the NHC selectively chemisorbs onto the metal surface. Annealing after deposition of NHC improves surface patterning by removing stray metal from the dielectric section.
