Abstract: The present disclosure relates to a continuous flow process for preparing conducting polymers, for example polyaniline. The continuous flow process can provide a controlled synthesis of a conducting polymer from an emulsion comprising a polymerizable organic monomer and a free radical initiator in flow within a temperature controlled continuous flow reactor comprising at least one mixing element. The present disclosure also relates to the conducting polymers prepared by the continuous flow process.

Abstract: This disclosure is directed to retention clamps that may be included in post-tensioning assemblies. More specifically, in some embodiments, a sheathing-retaining clamp for a post-tensioning assembly may comprise a body adjustable between an open position and a closed position, wherein in the closed position, the body is configured to wrap around a tendon assembly of the post-tensioning assembly, and a fastening mechanism configured to lock the body in the closed position. In some such embodiments, the sheathing-retaining clamp may additionally comprise a plurality of compression ribs that extend radially inwards from the body in the closed position and that are configured to directly contact a sleeve of the tendon assembly.

Abstract: A grow tube includes a first side, a second side, a first end portion, a second end portion, a first edge portion, a second edge portion, and a vent. The second side is opposite the first side, the second end portion is opposite the first end portion, the second edge portion is opposite the first edge portion, and the first and second edge portions and the first and second end portions define the first and second sides. The vent extends between the first side and the second side and comprises a flap and an opening. The vent can be V-shaped in some instances. The grow tube can also include one or more locking tabs and/or adjustment mechanisms, which allow the grow tube to be moved between tubular and flat configurations and/or allow a diameter of the grow tube in the tubular configuration to be adjusted, respectively.
