Trends in additively manufactured microfluidics, microreactors and catalytic materials

Abstract

The interest in microfluidics, that is the manipulation of fluids with volumes in the range of μL or below, have increased exponentially in the past decades, due to their relevance...

Dual Superlyophobic Materials for Under-Liquid Microfluid Manipulation, Immiscible Solvent Separation, and CO2 Blockage

“…Microfluid manipulation or transport is important for mass transfer and special chemical reactions . Thus, under-liquid microfluid manipulation and microdrop reaction were performed.…”

“…29 Microfluid manipulation or transport is important for mass transfer and special chemical reactions. 30 Thus, under-liquid microfluid manipulation and microdrop reaction were performed. As shown in Figure 4d and Video S1, the dual superlyophobic SMM was placed in petroleum ether, and a base drop containing phenolphthalein and an acid drop were then dripped on the SSM surface.…”

Wood-inspired dual-scale directional channel cellulose bioreactors with high mass transfer efficiency for continuous flow catalytic green conversion

“…4 In recent years, continuous catalytic immobilized enzyme reactors with directional channels have attracted considerable interest, because they generate low pressure and enable rapid flow. [5][6][7] In this type of reactor, the substrate in the channel quickly interacts with the catalyst to achieve efficient reaction, and several processes, such as subsequent centrifugal separation, are avoided, considerably reducing the process energy consumption and cost. 8,9 In addition, owing to the relatively uniform channel, industrial problems caused by pressure drop have been considerably improved.…”

Acoustic microfluidics for colloidal materials and interface engineering

“…1 By virtue of its unique merits in terms of ease-of-use, low-cost, portability, scalability, and automation, microfluidics has demonstrated effectiveness and improvements over conventional benchmark methods. [2][3][4][5][6][7] Although considerable progress has been achieved, the low Reynolds number at the microscale means that microfluidic devices face the critical challenge of process intensification inside the microchannels, which greatly limits their applicability. [8][9][10] To overcome this problem, researchers have developed many passive strategies that rely on the optimization of channel geometries and device configurations.…”
