An integrally formed umbrella framework comprises an upper nest, a lower nest, a plurality of long bones and the same number of supporting bones. The fluid line is configured to transfer a polymer fluid and solvent mixture to the spray head. The average height of the microcavity differs by not more than about 5 \u03bcm from the saturated particle thickness of the electrophoretic particle divided by the volume fraction of the electrophoretic particles in the internal phase. The user interface is operable to receive a user-input allocation of battery capacity among the subsystem circuits and functions. The liquid binder composition may include a protein and at least two crosslinking compounds that include a carbohydrate and an organic amine with two or more primary amines. These spacer compositions and spacer products may be utilized in well fluid operations, including well cementing operations and well completion operations.
