摘要： Methods and systems for chromatography are disclosed that employ a flexible container configured to fit within a support structure and adapted to receive a filtration or absorptive medium. The flexible container can include at least one inlet, at least one outlet, and a separation barrier peripherally sealed within the container to separate the container into a resin containing portion and a drainage portion. The barrier can be configured to exclude the resin material from the drainage portion while allowing fluids to pass therethrough. The disposable chromatography system can further include one or more agitators disposed within the flexible container and adjustably configured to be raised or lowered in the flexible container. When the agitator is in the raised position, the resin packing material can operate in a settled, packed-bed configuration. Alternatively, the agitator in the lowered position permits the chromatography resin packing material to operate in a mixed, slurry configuration.

摘要： Disclosed is direct ink write (DIW) print extrusion head for 3D printing of viscous elastomers. The disclosed print extrusion head comprises a mixer assembly, comprising a fluid distribution cap coupled to a carrier, an in-line mixer coupled to the fluid distribution cap. A cooling jacket surrounds the in-line mixer. A nozzle is coupled to the in-line mixer and protrudes below the cooling jacket over a work surface. The position of the nozzle relative to the work surface is changeable. At least one heat source is on the chassis and disposed adjacent to the fluid distribution cap. The at least one heat source comprises a heat guiding element to direct heat to a region onto the work surface below the nozzle.

摘要： A system for performing a gas-liquid mass transfer includes a container bounding a compartment and having a top wall, a bottom wall, and an encircling sidewall extending therebetween. A tube has a first end and an opposing second end, the first end of the tube being disposed within the compartment of the container. A nozzle is disposed within the compartment of the container and has at least one outlet, the nozzle being coupled with the tube so that a gas can be passed through the tube and out the at least one outlet of the nozzle. The nozzle is sufficiently buoyant so that when a fluid is disposed within the compartment of the container, the nozzle floats on the fluid.
