A triphasic liquid system fabricated from isooctane, aqueous base, and trioctylmethylammonium chloride/decanol promoted the formation of Pd-nanoparticles in the size range of 2-4 nm which remained immobilised in the onium phase, catalysed organic reactions, and could be recycled.

Due to their superior optical and electrical properties, gold nanowires are used ubiquitously across industries. Current techniques for fabricating such structures are often expensive, involving multiple steps, cleanroom operation, and limited ability for a user to controllably place a nanowire at a desired location. Here, we introduce the concept of triphasic electrodeposition, where metal salts act as antagonistic salts at the liquid|liquid interface, leading to their increased concentration at this phase boundary.

Owing to its ability to separate substances with a broad scope of polarities, exploring the three-phase solvent systems (TPSSs) with high-speed countercurrent chromatography is a topic of interest in separation science, and their retention volumes should be more concerned. This study primarily investigates the behavior of retention volumes while examining the isolation abilities of the TPSS in the technique above. We took standard compounds, including sophoricoside, Sudan red 7B, and rotenone, which have a broad range of polarity, for investigation in this study and separated them using different four-liquid TPSSs made up of water, acetonitrile, methyl acetate, and n-hexane (WAMH).

Using heterogeneous single-atom catalysts (SACs) in the Suzuki-Miyaura coupling (SMC) has promising economic and environmental benefits over traditionally applied palladium complexes. However, limited mechanistic understanding hinders progress in their design and implementation. Our study provides critical insights into the working principles of Pd@CN, a promising SAC for the SMC.

Oxidase enzyme-based electrochemical bioassays have garnered considerable interest due to their specificity and high efficiency. However, in traditional solid-liquid diphase enzyme electrode systems, the low solubility of oxygen and its slow mass transfer rate limit the oxidase catalytic reaction kinetics, thereby affecting the bioassay performance, including the detection accuracy, sensitivity, and linear dynamic range. ZIF-8 nanoparticles (NPs) possess hydrophobic and high-porosity characteristics, enabling them to serve as oxygen nanocarriers.

Bioassay systems that can selectively detect biomarkers at both high and low levels are of great importance for clinical diagnosis. In this work, we report an enzyme electrode with an oxygen reduction reaction (ORR)-tolerant HO reduction property and an air-liquid-solid triphase interface microenvironment by regulating the surface defects and wettability of nanoporous tin oxide (SnO). The enzyme electrode allows the oxygen that is required for the oxidase catalytic reaction to be transported from the air phase to the reaction zone, which greatly enhances the enzymatic kinetics and increases the linear detection upper limit.
