Facile synthesis of amino-modified magnetic covalent organic framework for the efficient extraction and determination of anionic azo dyes in carbonated beverages.

In this work, a novel magnetic covalent organic framework (COF (TpPa-NH) @ FeO) was prepared via two step by simple solvent method for the extraction of anionic azo dye residues in food. The as-prepared COF (TpPa-NH) @ FeO nanocomposite was characterised by scanning electron microscope, transmission electron microscope, Fourier transform-infrared spectroscopy, X-ray diffraction and vibrating sample magnetometer. Before high-performance liquid chromatography with ultraviolet detection (HPLC-UV) determination, it was used as magnetic adsorbent for magnetic solid-phase extraction (MSPE) to extract and pre-concentrate three anionic azo dyes in carbonated beverage samples.

Love Is Blind! Exploring the Impact of Brand Love on eWOM in Chinese Hospitality Industry.

The rising penetration and value of online information reviews in the hospitality industry have been extensively examined. People are increasingly interacting on interactive online media, prompting firms to create online communities to share electronic word-of-mouth (eWOM) with them and with one another in order to increase brand love. This study seeks to discover what drives consumers to participate in these online brand communities.

Use of a magnetic covalent organic framework material with a large specific surface area as an effective adsorbent for the extraction and determination of six fluoroquinolone antibiotics by HPLC in milk sample.

A magnetic covalent organic framework material was synthesized with a core-shell structure using a simple solvothermal method. It was prepared with Fe O as the magnetic core, covalent organic framework as the shell, which synthesized from 1,3,5-triformylphloroglucinol and p-phenylenediamine by Schiff base reaction. Transmission electron microscopy, Fourier transform infrared spectroscopy, powder X-ray diffraction, vibrating sample magnetometry, and nitrogen adsorption-desorption were used to characterize magnetic adsorbent.

Novel magnetic g-CN/α-FeO/FeO composite for the very effective visible-light-Fenton degradation of Orange II.

A novel magnetic heterogeneous g-CN/α-FeO/FeO catalyst was successfully synthesized through a simple hydrothermal method. The structure, morphology, and optical properties of the catalyst were characterized. The photocatalytic activity of the heterogeneous g-CN/α-FeO/FeO catalyst for the photo-Fenton degradation of Orange II in the presence of HO irradiated with visible light ( > 420 nm) at neutral pH was evaluated.

Corn-like, recoverable γ-FeO@SiO@TiO photocatalyst induced by magnetic dipole interactions.

Corn-like, γ-FeO@SiO@TiO core/shell heterostructures were synthesized by a modified solvothermal reduction combined with a sol-gel method. SiO shells were first deposited on monodisperse FeO microspheres by a sol-gel method. FeO@SiO@TiO corn-like heterostructures were then obtained by sequential TiO coating, during which the magnetic dipolar interactions induced the anisotropic self-assembly process.

Establishment of complete blood count reference intervals for Chinese preschoolers.

Background: Reference intervals are critical for interpreting test results of a clinical laboratory. The aim of this study was to establish local reference intervals of complete blood count for healthy preschoolers in China.

Methods: Three thousand eight hundred and twenty-one blood specimens from children aged 4 months to 6 years were collected and analyzed.
