The 239th ECS Meeting and the 18th International Meeting on Chemical Sensors (IMCS) bring together the most active researchers in academia, government, and industry—both professionals and students—to engage, discuss, and innovate in the areas of electrochemistry and solid state science and technology. This is the premier destination for industry professionals to experience five days of learning, technical presentations, business development, and networking opportunities. The 239th ECS and 18th IMCS meetings will be held as scheduled as fully digital events. Rather than travelling to Chicago, all presenting authors are requested to submit digital presentation files (video, and/or slide deck or poster) in advance of the meeting. These materials will be freely available to all global attendees for on-demand viewing throughout the meeting dates.
