摘要： Devices and methods suitable for cell separation. The devices herein include non-random voids interconnected through non-random pores and/or non-random solid geometrical structures optionally connected through solid non-random interconnecting elements. Such devices are preferably suitable for affinity-based cell isolation techniques which rely upon binding interactions.

摘要： Technologies for reducing the viscosity of heavy crude oil are disclosed. In embodiments the technologies utilize a combination of a processing additive composition (PAC) and hydrodynamic cavitation to produce an oil composition having a viscosity V2, wherein V2 is at least 40% less than a viscosity V1 of untreated heavy crude oil. PACs, systems for reducing the viscosity of heavy crude oil using a combination of a PAC and hydrodynamic cavitation, and methods for reducing the viscosity of heavy crude oil with a combination of a PAC and hydrodynamic cavitation are also disclosed.

摘要： A system for providing microwave energy to aftertreatment devices that treat the exhaust of an internal combustion engine. The system has a microwave generator and a transmission network for delivering the microwaves to one or more of the aftertreatment devices. The transmission network comprises a combination of solid and hollow waveguides. Antenna(s) transmit microwave energy into the working chamber the aftertreatment device(s), with at least one of the devices having antenna(s) capable of distributing microwave energy throughout its chamber.

摘要： An engine with a vertically oriented parallel valve and stem arrangement accommodating tumble flow to support spark-ignited fuel usage. The engine may be provided in a configuration generally suited for swirl flow, compression combustion fuel usage. However, the introduction of a unique, replaceable valve head assembly may be utilized to induce tumble flow within a combustion chamber of the engine. Thus, spark-ignited fuel may be utilized without requiring vast overhaul of the engine to accommodate such fuels. Notably, with the addition of such an assembly, diesel fuel may be replaced with natural gas on large scale equipment without the requirement of impractically burdensome or expensive measures.

摘要： Design, fabrication and applications of three-dimensional (3D) bioreactor for cell expansion and cell secreted substance production. The bioreactors have relatively low levels of potentially cytotoxic compounds, can be coated with substituted or unsubstituted poly(p-xylene) type coatings and can also be separately formed from liquid crystal photopolymerizable monomers.

摘要： A retainer apparatus configured to releasably retain an article, comprising a face plate member each having a front face; a plurality of vacuum cups and a plurality of support pins each extending distally relative to the front face, respectively; wherein the vacuum cups and the support pins are laterally spaced from one another; wherein the plurality of vacuum cups retain the article to the retainer apparatus in a presence of vacuum; wherein the plurality of support pins are extendable/retractable relative to the face plate member, wherein each of the support pins have a longitudinal axis, respectively, and are configured to contact the article to support the article against movement along the longitudinal axis and support the article against movement transverse to the longitudinal axis; and a locking mechanism configured to inhibit the support pins from being retractable and extendable when the locking mechanism is engaged.

摘要： A test system for detecting corrosion under a coating on a structure, the coating being transmissive to microwaves and the surface being reflective to microwaves. A microwave generator generates microwaves of a desired power and frequency, which are delivered to a test head that both transmits the microwaves to the surface and receives the microwaves as reflected from the structure. A corrosion detection processor measures the phase and amplitude of the reflected signal, and compares measurement data to reference data to determine if corrosion under the coating is indicated.

摘要： A hydraulic lash assembly (HLA) for use in a valvetrain. The HLA preferably includes a first arm configured to transition a valve between a closed orientation and an open orientation. The first arm can include an engagement surface to receive a driving force from a timing member and to cause the valve to transition to the open orientation for a predetermined period. The HLA further preferably includes a second arm to receive a holding force from an actuator and a pivot section to couple to the first arm and displace the first arm based on the holding force from the actuator. Preferably, the first arm and the second arm form a lever arrangement whereby the pivot section of the second arm underlies and supports the first arm and allows for rotational movement of the first arm that is independent from the second arm.

摘要： A system for using excess energy of a power generation system and an sCO2 (supercritical carbon dioxide) stream to store and generate power. An air separation unit uses the excess energy to cool and liquify ambient air into liquid nitrogen (L-N2) and liquid oxygen (L-O2). The L-O2 and L-N2 are stored until energy is desired. An L-O2 energy discharge path has an oxygen heat exchanger that vaporizes and heats the oxygen, a combustor that combusts the oxygen and fuel to produce exhaust, and a first turbine is driven by the exhaust to produce energy. An L-N2 energy discharge path has a nitrogen heat exchanger that vaporizes and heats the L-N2, thereby providing expanded nitrogen, and a second turbine is driven by the expanded nitrogen to produce energy. Heat for the heat exchangers on both discharge paths is provided by the sCO2 stream.

摘要： The present invention is directed at the integration of a solid oxide fuel cell (SOFC) into the exhaust stream of an internal combustion engine aided by the upstream injection of a fuel, such as a hydrocarbon fuel. The internal combustion engine may be advantageously operated in a lean condition while the SOFC receives the hydrocarbon fuel to promote and maintain optimized fuel cell operation.
