Here we report an integrated microdevice consisting of efficient passive mixer, a magnetic separation chamber, and capillary electrophoretic microchannel in which DNA barcode assay, target pathogen separation, analysis were performed sequentially within 30 min for multiplex detection at the single-cell level. The intestine-shaped serpentine 3D micromixer provides high mixing rate to generate particle–pathogenic bacteria–DNA labelled AuNP complexes quantitatively. After purification those...

A highly sensitive enzyme electrode was prepared based on gold nanoparticles for measurement of pesticides. Gold 25–30 nm were synthesized a glassy carbon by double-pulse technique while the coverage controlled applied potential and time. The modified to form self-assembled monolayer, followed covalent binding tyrosinase. TYR-AuNP-GC compared with bare GC, AuNP-GC, AuNP-GC TYR-Au (plate type) electrodes in terms cyclic voltammetry. voltammograms well represent sensitivity enzymatic oxidation...

Deep geological disposal using a multibarrier system is promising solution for treating high-level radioactive (HLRW) waste. The HLRW canister represents the first barrier migration of radionuclides into biosphere, therefore, corrosion behavior materials significance. In this study, electrochemical behaviors SS316L, Ti-Gr.2, Alloy 22, and Cu in naturally aerated KAERI underground research tunnel (KURT) groundwater solutions were examined. potential, current, impedance spectra test recorded...

In a deep geological disposal system, bentonite buffer material is an important barrier used to protect the canister from inflow of groundwater and prevent outflow radionuclides. This study aimed characterize mineralogical chemical reactions caused by copper corrosion in radioactive waste repository. We investigated d-spacings montmorillonite Gyeongju (Ca-type, KJ-I) under groundwater-saturated conditions over 10 years compared their characteristics with those Wyoming (Na-type, MX-80) Korea...

This study was carried out to examine the removal of rare earth (RE) elements by electrodeposition for purification and reuse LiCl-KCl salt after electrorefining electrowinning. The electrochemical behavior RE (Dy Gd) in LiCl-KCl-DyCl 3 -GdCl at 500°C investigated using cyclic voltammetry (CV) technique Mo Mg electrodes. It observed that reduction potential shifted electrode owing alloy formation with (RE-Mg alloy). Subsequently, a series potentiostatic electrolysis tests were conducted...

Application of square wave voltammetry (SWV), a pulse technique without renewal the diffusion layer between waves, was demonstrated for quantitative analysis lanthanide concentrations. The reproducible measurement conditions in molten salt were investigated terms principal parameters such as height and frequency getting proper calibration curve. It observed that peak current SWV increased when gadolinium concentration less than 1 wt%. In addition, total amount lanthanides binary solutions...

Deposition behaviors of Sr and Cs in various liquid cathodes, such as Zn, Bi, Cd, Pb, were examined to evaluate their recovery from LiCl–KCl eutectic salt. Cations the salt deposited on cathode, exhibiting potential −1.8 −2.1 V (vs. Ag/AgCl). Zn cathode had successful deposition exhibited highest efficiency, up 55%. Meanwhile, other cathodes showed low current efficiencies, below 18%, indicating decomposition. was recovered irregular rectangular SrZn13 particles. A negligible amount entire...
