A flexible, durable, and solvent‐resistant inorganic polymer‐based microstructured solution‐shearing blade is demonstrated by Steve Park and co‐workers in article number 1800647 . The dimension and shape of the microstructure are used to tune the curvature of the meniscus formed between the shearing blade and the substrate, which is utilized to manipulate the crystal size of organic thin films. Such a novel technique to control the crystal size is potentially applicable to other thin‐film crystallization systems.
