FeO-Loaded g-CN/C-Layered Composite as a Ternary Photocatalyst for Tetracycline Degradation.

A ternary photocatalyst, FeO-loaded g-CN/C-layered composite (g-CN/C/FeO) was fabricated by a facile sonication and in situ precipitation technique. Carbon nanosheets were prepared using the remaining non-metallic components of waste printed circuit boards as carbon sources. In this hybrid structure, g-CN was immobilized on the surfaces of carbon nanosheets to form a layered composite, and 10-15 nm FeO nanoparticles are uniformly deposited on the surface of the composite material.

Microwave-assisted synthesis of 3D BiMoO microspheres with oxygen vacancies for enhanced visible-light photocatalytic activity.

Oxygen vacancies (OVs) defects in metal oxide-based photocatalysts play a crucial role in improving the charge carrier separation efficiencies to enhance the photocatalytic performances. In this work, OVs were introduced in 3D BiMoO microspheres through a facile and fast microwave-assisted method via the modulation of tetramethylethylenediamine (TMEDA). EPR, Raman and XPS results demonstrated that large amounts of oxygen vacancies were formed on the surface of BMO microspheres.

Microwave Solvothermal Synthesis of Three-Dimensional BiMoO Microspheres with Enhanced Photocatalytic Activity.

In this study, three-dimensional (3D) BiMoO microspheres were successfully fabricated by a facile, rapid, and mild microwave solvothermal strategy for the first time. The resultant 3D BiMoO microspheres exhibited superior adsorption capacity and photocatalytic efficiency in the degradation of the representative antibiotic ciprofloxacin under visible light, for which the reaction kinetic rate constant is 7.5 times as high as that of the as-synthesized zero-dimensional BiMoO nanoparticles.

Bifunctional NiAlFe LDH-coated membrane for oil-in-water emulsion separation and photocatalytic degradation of antibiotic.

A new NiAlFe layered double hydroxide/polydopamine/polyvinylidene fluoride (NiAlFe LDH/PDA/PVDF) membrane was fabricated by in-situ growth of LDH on the PDA modified PVDF membrane. The as-prepared membrane possesses a nano/microscale rough structural surface and displays the superior wettability of superhydrophilicity in air and underwater superoleophobicity. Combining the favourable features of superwettability and hierarchical rough structure, the NiAlFe LDH/PDA/PVDF membrane could effectively separate a series of oil-in-water emulsions with high efficiency (>99%) and high permeation flux (925-1913 L m h bar).

[Prenatal diagnosis of two cases with 2p15-p16.1 microdeletion syndrome].

Objective: To detect chromosomal aberrations in two fetuses with multiple malformation.

Methods: The two fetuses were subjected to chromosomal microarray analysis (CMA) by using Affymetrix CytoScan 750K arrays. The results were analyzed by bioinformatic software.

Facile Fabrication of C-TiO Nanocomposites with Enhanced Photocatalytic Activity for Degradation of Tetracycline.

Visible-lightdriven C-TiO nanocomposites were prepared via a simple calcination and acid etching process. The C-TiO nanocomposites were characterized by X-ray photoelectron spectroscopy, Raman spectroscopy, X-ray diffraction, transmission electron microscopy, and high-resolution TEM. The results showed that TiO nanoparticles were combined with a porous carbon layer through surface C-O groups, which facilitates the strong interface interaction.

[Genetic analysis of two fetuses with congenital heart defects and 3q microdeletion].

Objective: To determine the nature of genomic copy number variations (CNVs) in two fetuses with congenital heart defects (CHD) and explore the correlation between 3q microdeletions and CHD.

Methods: Genomic DNA was extracted from fetal umbilical cord tissue, and chromosome copy number variations were detected by low coverage whole genome sequencing.

Results: Both fetuses had microdeletions of the long arm of chromosome 3.

LTPB2 acts as a prognostic factor and promotes progression of cervical adenocarcinoma.

Latent transforming growth factor-beta-1 binding protein-2 (LTBP-2) is a member of the fibrillin/LTBP super family of extracellular matrix proteins, found to be overexpressed in certain malignant tumors. However, the clinical significance and biological role of LTBP-2 in cervical adenocarcinoma has remains unclear. We found that the expression of LTBP2 was higher in cervical adenocarcinoma than in normal cervical epithelial tissue as assessed by immunohistochemistry.
