Organized Hypocrisy as a Tool of Climate Diplomacy

A method and system for making a gas permeable shell in a micro electromechanical systems (MEMS) device is disclosed. The MEMS device is created with an internal sacrificial layer. The device is then coated with a slurry composition which, after drying, is later exposed to a solvent. As a result, the sacrificial layer is removed to produce interconnected voids.
