Disclosed herein is a constant shear continuous reactor device, comprising: an annular gas delivery tube comprising a gas inlet and a gas outlet; a first annular liquid delivery tube comprising a first liquid inlet and a first liquid outlet arranged concentrically around the annular gas delivery tube along a common axis, where the first liquid outlet is located at a downstream position relative to the gas outlet or is coterminous with the gas outlet; and an annular reactor wall tube comprising a final liquid inlet, a mixing zone section and a reactor outlet, where the annular reactor wall tube is arranged concentrically around the first annular liquid delivery tube along the common axis.

A system is described that is capable of operating as an energy conversion system that functions as a fuel cell and generates electrical current from a fuel or fuels, or as a reactor for conversion of starter materials into more complex molecules through ion-ion and ion-molecules and which may preferably be adapted to operate as a gas to liquid (GTL) process. The system ionises at least one fuel or starter material and manipulates, selects and transports ions for reaction by means of suitable electrostatic or electrodynamic ion guides, filters or drift tubes. The system of the present application replaces the electrolyte, catalyst and/or membrane found in classic fuel cells or GTL processes with an electrostatic or electrodynamic ion manipulation region such as an ion guide, analyser, drift tube or filter.

The present invention relates to a device for the photocatalytic reduction of a substance with a structured reaction plate and/or a structured housing, wherein the reaction plate has, at least in some regions, a surface which contains a material with negative electron affinity and which can be electronically excited with radiation having a wavelength of ≥180 nm.

An automated radiopharmaceutical production and quality control system includes a particle accelerator, a radiopharmaceutical micro-synthesis subsystem, and quality control subsystem. The micro-accelerator of the improved biomarker generator is optimized for producing radioisotopes useful in synthesizing radiopharmaceuticals in quantities on the order of multiple unit doses, allowing for significant reductions in size, power requirements, and weight when compared to conventional radiopharmaceutical cyclotrons. The radiopharmaceutical micro-synthesis subsystem encompasses a small volume chemical synthesis system comprising a microreactor and/or a microfluidic chip and optimized for synthesizing the radiopharmaceutical in small quantities, allowing for significant reductions in processing time and in the quantity of radioisotope required. The automated quality control subsystem is used to test the composition and characteristics of the radiopharmaceutical to ensure that it is safe to inject.

A microfluidic system, including: a container, an ultrasound transmitter assembly, and a phononic crystal plate. The container is configured to accommodate a solution containing microparticles. The ultrasound transmitter assembly is configured to transmit ultrasonic waves to the phononic crystal plate, where the ultrasonic waves have a frequency which is the same as a resonance frequency of the phononic crystal plate. The phononic crystal plate is placed in the solution, and configured to generate a local acoustic field on a surface of the phononic crystal plate under excitation of the ultrasonic waves, and induce an acoustic microstreaming vortex to generate an acoustic streaming shear stress on the microparticles. The phononic crystal plate defines therein cavities, the respective cavities are arranged periodically in the phononic crystal plate, and all the respective cavities are filled with gas.
