Rare earth doping: a strategy to enhance the catalytic activity of ZnFeO in activating peroxymonosulfate for acetaminophen degradation.

In this paper, ZnFeO was doped by two rare earth metals (La and Pr), and the as-prepared ZnLaFeO and ZnPrFeO were applied to activate PMS for acetaminophen degradation. ZnLaFeO with the largest oxygen vacancy (O) content showed the highest acetaminophen degradation efficacy. About 89.

Novel heterogeneous Fenton catalysts prepared using electrolytic manganese residue for efficient degradation of acetaminophen.

Electrolytic manganese residue (EMR) was used as a support to prepare novel EMR-supported catalysts for the heterogeneous Fenton degradation of acetaminophen. Among the five supported catalysts, Co/EMR showed the highest catalytic activity. Several important factors influencing the decay of acetaminophen, including Co loading content, catalyst dosage, HO concentration and initial solution pH, were investigated.

Discovery of new tricyclic spiroindole derivatives as potent P-glycoprotein inhibitors for reversing multidrug resistance enabled by a synthetic methodology-based library.

The discovery of novel and highly effective P-gp inhibitors is considered to be an effective strategy for overcoming tumor drug resistance. In this paper, a phenotypic screening a self-constructed synthetic methodology-based library identified a new class of tricyclic spiroindole derivatives with excellent tumor multidrug resistance reversal activity. A stereospecific compound OY-103-B with the best reversal activity was obtained based on a detailed structure-activity relationship study, metabolic stability optimization and chiral resolution.

Manipulating the formation of cesium lead bromide nanocrystals oleic acid.

To realize the precise modulation among the cesium lead halide perovskite-related phases is one of the most fascinating subjects and has motivated increasing research. The formation mechanisms of different phases of cesium lead halide have not been fully recognized. In this work, we reported the phase-selective synthesis of CsPbBr nanorods and CsPbBr nanocrystals (NCs) in amine-free systems, simply by adjusting the dosage of oleic acid (OA).

Research on the on-line determination of formaldehyde gas by the gas-liquid phase chemiluminescence method.

Based on the gas-liquid phase chemiluminescence tester independently developed by our laboratory, a highly sensitive, fast and accurate on-line detection method of formaldehyde gas in ambient atmosphere is established. The chemiluminescence system and the trace formaldehyde gas in the air directly undergo an interface heterogeneous chemiluminescence reaction to obtain a strong chemiluminescence signal. Through the measurement of the chemiluminescence signal intensity, a highly sensitive, real-time and on-line method for the determination of formaldehyde in the air was established.

Development of Au NPs-decorated filter paper as a SERS platform for the detection of benzidine.

In this paper, a simple and cost-efficient strategy was used to construct a uniform Au NPs distribution on the surface of flexible filter paper for the detection of benzidine. Taking full advantage of the adsorption properties of filter paper, small gold nanoparticles were adsorbed onto its surface as gold seeds, and subsequently grown by electroless plating to form a highly uniform distribution of Au NPs substrates. By changing the electroless plating time, an optimal substrate was obtained.

The effect of sintering process on lithium ionic conductivity of LiAlLaZrO garnet produced by solid-state synthesis.

Recently, solid-state electrolyte lithium lanthanum zirconium oxide garnet (LiLaZrO, LLZO) has attracted great attention due to its high room temperature conductivity of lithium ions and stability against lithium metal electrodes. The Al-doped cubic garnet LiAlLaZrO was synthesized by a conventional solid-state method at different sintering temperatures. The influence of the sintering process on the structure and ionic conductivity was investigated by X-ray diffraction, electrochemical impedance spectroscopy, and scanning electron microscopy.
