The design for a reversible microfluidic coupler is proposed for use with microreactors and other MEMS devices. However, real couplers will include imperfections that must be considered to fully evaluate the degree of sealing. A method is presented for applying a normally distributed surface finish with a predetermined amplitude to a perfectly flat contact surface. The method is then applied to...

Nuclear energy is being reconsidered worldwide as a low-carbon and dispatchable source. Following the development of Small Modular Reactors (SMR) to reduce capital costs increase safety new nuclear power plants, microreactors are designed by several companies. Microreactors usually defined SMR with output in range 1–20 MWe. They can operate part electric grid, independently from grid or microgr...

Introduction Currently, there is tremendous interest in the field of micro-structured gas-liquid contactors containing modified catalytic coatings on its micro-structured internals (Fig. 1) [1]. The most recent trend in the design of three-phase catalytic microreactors focuses on the use of structured catalyst supports, i.e. that the catalyst has to be deposited on a rigid, orderly arranged sup...

In this paper the fabrication and electrical characterization of a silicon microreactor for high-temperature catalytic gas phase reactions, like Rh-catalyzed catalytic partial oxidation of methane into synthesis gas, is presented. The microreactor, realized with micromachining technologies, contains silicon nitride tubes that are suspended in a flow channel. These tubes contain metal thin films...

Proteolytic digestion is an essential step in proteomic sample processing. While this step has traditionally been implemented in homogeneous (solution) format, there is a growing trend to use heterogeneous systems in which the enzyme is immobilized on hydrogels or other solid supports. Here, we introduce the use of immobilized enzymes in hydrogels for proteomic sample processing in digital micr...

Artificial Cells In article number 2202962, Yoon-Kyoung Cho and co-workers discuss the latest advances in cell membrane-engineered micro or nanoreactors that simulate biochemical compartments, signaling cascades, energy generation, growth, reproduction, adaptability. These reactors have potential to provide hybrid solutions for pharmaceutical drugs, biosensors, novel materials, microreactors.

In the field of positron emission tomography (PET) radiochemistry, compact microreactors provide reliable and reproducible synthesis methods that reduce the use of expensive precursors for radiolabeling and make effective use of the limited space in a hot cell. To develop more compact microreactors for radiosynthesis of 18F-labeled compounds required for the multistep procedure, we attempted ra...
