Abstract: The invention is a high-throughput voltage screening crystallographic device and methodology that uses multiple micro wells and electric circuits capable of assaying different crystallization condition for the same or different proteins of interest at the same of different voltages under a humidity and temperature controlled environment. The protein is solubilized in a lipid matrix similar to the lipid composition of the protein in the native environment to ensure stability of the protein during crystallization. The invention provides a system and method where the protein is transferred to a lipid matrix that holds a resting membrane potential, which reduces the degree of conformational freedom of the protein. The invention overcomes the majority of the difficulties associated with vapor diffusion techniques and essentially reconstitutes the protein in its native lipid environment under “cuasi” physiological conditions.

Abstract: A catalytic membrane composite that includes porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane is provided. The porous fibrillated polymer membrane may be manipulated to take the form of a tube, disc, or diced tape and used in multiphase reaction systems. The supported catalyst particles are composed of at least one finely divided metal catalyst dispersed on a porous support substrate. High catalytic activity is gained by the effective fine dispersion of the finely divided metal catalyst such that the metal catalyst covers the support substrate and/or is interspersed in the pores of the support substrate. In some embodiments, the catalytic membrane composite may be introduced to a stirred tank autoclave reactor system, a continuous flow reactor system, or a Parr Shaker reaction system and used to effect the catalytic reaction.

Abstract: We describe vortical thin layer film flow along a spiral channel designed to improve mass and heat transfer efficiency for a multitude of physicochemical reactions and processes. Spiral channels, commonly augmented by centrifugal rotation, support rapid reaction between one or more fluids in a given channel. Dean vortices generate screw-shaped patterns processing axially in the channel, repeatedly refreshing radial interfaces. Fluids self-align, self-assemble, stable, controllable, exhibit thin film geometry. Multiple discrete lamellae can flow with independent velocity separated by density and may be soluble or insoluble in one another. Membranes separating spirals allow other interactions. Energy can be provided and extracted from each flow. Flows can enter or exit independently along the channel length. The pressure within each channel is controlled even when operated at the liquid's vapor pressure. The device is scalable to include a multiplicity of flows in a multiplicity of centrifugally rotating chambers.

Abstract: A self-regulating gas generator that, in response to gas demand, supplies and automatically adjusts the amount of gas (e.g., hydrogen or oxygen) catalytically generated in a chemical supply chamber from an appropriate chemical supply, such as a chemical solution, gas dissolved in liquid, or mixture. The gas generator may employ a piston, rotating rod, or other element(s) to expose the chemical supply to the catalyst in controlled amounts. The gas generator may be used to provide gas for various gas consuming devices, such as a fuel cell, torch, or oxygen respiratory devices.
