MoS@MWCNTs with Rich Vacancy Defects for Effective Piezocatalytic Degradation of Norfloxacin via Innergenerated-HO: Enhanced Nonradical Pathway and Synergistic Mechanism with Radical Pathway.

Molybdenum disulfide (MoS)-based materials for piezocatalysis are unsatisfactory due to their low actual piezoelectric coefficient and poor electrical conductivity. Herein, 1T/3R phase MoS grown in situ on multiwalled carbon nanotubes (MWCNTs) was proposed. MoS@MWCNTs exhibited the interwoven morphology of thin nanoflowers and tubes, and the piezoelectric response of MoS@MWCNTs was 4.

Preparation and photocatalytic performance study of dual Z-scheme BiZrO/g-CN/AgPO for removal of antibiotics by visible-light.

At present, the high re-combination rate of photogenerated carriers and the low redox capability of the photocatalyst are two factors that severely limit the improvement of photocatalytic performance. Herein, a dual Z-scheme photocatalyst bismuthzirconate/graphitic carbon nitride/silver phosphate (BiZrO/g-CN/AgPO (BCA)) was synthesized using a co-precipitation method, and a dual Z-scheme heterojunction photocatalytic system was established to decrease the high re-combination rate of photogenerated carriers and consequently improve the photocatalytic performance. The re-combination of electron-hole pairs (e and h) in the valence band (VB) of g-CN increases the redox potential of e and h, leading to significant improvements in the redox capability of the photocatalyst and the efficiency of e-h separation.

Effective mineralization of p-nitrophenol by catalytic ozonation using Ce-substituted LaCeFeO catalyst.

In this study, cerium-doped lanthanum ferrite perovskite oxides (LaCeFeO) with different A-site were synthesized using a sol-gel method and they were used as ozonation catalyst for p-nitrophenol (PNP) mineralization for the first time. Catalytic activity in terms of total organic carbon (TOC) removal followed the order of LaCeFeO > LaCeFeO > LaCeFeO > LaCeFeO > LaFeO with 77, 66, 61, 60 and 56% respectively. The synthesized catalysts were characterized by diffraction of X-ray (XRD), Raman spectroscopy, Brunauer-Emmett-Teller (BET) and scanning electronic microscopy (SEM).

Metabonomics study of essential hypertension and its chinese medicine subtypes by using gas chromatography-mass spectrometry and nuclear magnetic resonance spectroscopy.

A metabonomic study was performed to investigate the metabolic mechanism of essential hypertension and its Chinese medicine subtypes, including "Yin-deficiency and Yang-hyperactivity syndrome" (YDYHS) and "Yin-Yang deficiency syndrome" (YYDS). Plasma samples from 22 healthy volunteers, 31 hypertensive patients with YDYHS, and 29 hypertensive patients with YYDS were analyzed by (1)H-NMR spectroscopy and gas chromatography coupled with mass spectrometry (GC-MS). The three groups were distinctly classified by principal components analysis (PCA) and partial least squares discriminant analysis (PLS-DA).
