  • Patent number: 11209411
    Abstract: The invention generally relates to methods for analyzing stability of an active pharmaceutical agent. In certain aspects, the methods involve obtaining an active pharmaceutical agent, and distributing the active pharmaceutical agent into one or more microdroplets. The one or more microdroplets including the active pharmaceutical agent are then subjected to one or more conditions that force degradation of the active pharmaceutical agent in each of the one or more microdroplets. The one or more microdroplets are then analyzed to determine a ratio of the active pharmaceutical agent to that of a degradation product of the active pharmaceutical agent, thereby analyzing stability of an active pharmaceutical agent.

  • Publication number: 20210357078
    Abstract: A touch panel, a method for manufacturing the same and a display device are provided in the disclosure. The method for manufacturing the touch panel includes: forming a first conductive layer on a base substrate; performing a patterning process on the first conductive layer to form a first conductive layer pattern, wherein the first conductive layer pattern includes two etched regions and a non-etched region which are formed at a preset intersection position where a first touch electrode and a second touch electrode intersect with each other; forming an insulation pattern at the preset intersection position, wherein the insulation pattern is filled in the two etched regions and covers the non-etched region; forming a second conductive layer, wherein the first conductive layer and the second conductive layer constitute a conductive layer; and performing a patterning process on the conductive layer.
