Abstract: Transitioning conventional x-ray detector materials and structures to bendable or flexible (e.g., plastic) substrates makes them rugged against breakage when dropped but exposes the detectors to damage if bent. Disclosed are bendable digital x-ray detector structures that are rugged with regard to bending as well as dropping. The structures provide strain matching between layers so that a detector backplane is in and/or near the mechanical neutral plane and therefore less susceptible to bending stress.

Abstract: One embodiment provides a chemical reactor, which can comprise a substrate for facilitating chemical reactions occurring at triple-phase boundaries. One possible substrate may further comprise a set of dynamically controllable sites and/or pixels upon which control signals may affect a desired formation of gas bubbles over an active catalytic (or other desired) solid surface in a liquid flow—wherein a chemical reaction in two or more phase boundaries may occur. In yet another embodiment, a control algorithm may send control signals to controllable sites/pixels to maximize the operation of the reactor according to a desired metric (e.g., product formation) that may input a set of sensor data to affect its control.
