Protective and Flame-Retardant Bifunctional Epoxy-Based Nanocomposite Coating by Intercomponent Synergy between Modified CaAl-LDH and rGO.

Extensive utilization in various settings poses extra requirements of coatings beyond just anticorrosion properties. Herein, 8-hydroxyquinoline (8-HQ) intercalated CaAl-based layered double hydroxide (CaAl-8HQ-LDH) was loaded on reduced GO (rGO) through a one-pot hydrothermal reaction, which was employed as the nanofiller endowing the epoxy (EP/CaAl-8HQ LDH@rGO) with excellent flame-retardancy while ensuring efficient protection for mild steel. Results of electrochemical impedance spectroscopy (EIS) demonstrated the durability of the EP/CaAl-8HQ LDH@rGO-coated specimen, with the impedance at the lowest frequency (||) maintained as 1.

A Mine Water Source Prediction Model Based on LIF Technology and BWO-ELM.

The traditional methods for identifying water sources in coal mines lack the ability to quickly detect water sources and are prone to causing secondary pollution of samples. In contrast, laser induced fluorescence (LIF) technology has been introduced for the identification of coal mine water sources due to its high sensitivity and real-time performance. However, extreme learning machine (ELM) have shortcomings in randomly selecting weights and biases.

Research on transformer fault diagnosis based on an IWHO optimized MS1DCNN algorithm and LIF spectrum.

Accurate diagnosis of transformer faults can effectively improve the enduring reliability of power grid operation. Aiming at overcoming the problems of long time consumption and low diagnostic rate in the past diagnosis methods, this article designs a laser-induced fluorescence (LIF) detection system, which can be combined with a multi-scale one-dimensional convolution neural network (MS1DCNN) to diagnose transformer fault categories. The structural parameters of MS1DCNN are optimized using the improved wild horse optimizer (IWHO).

Synthesis and Characterization of a Novel Apple Pectin-Fe(III) Complex.

In the present study, apple pectin (AP) extracted from apple pomace was used to chelate with Fe(III) to synthesize an AP-Fe(III) complex. The obtained AP-Fe(III) complex was characterized by UV-vis spectroscopy, FTIR, XPS, and TG analysis. The Fe content in the AP-Fe(III) complex was determined to be 24.

Extraction of Low Methoxyl Pectin from Fresh Sunflower Heads by Subcritical Water Extraction.

Subcritical water extraction (SWE) of pectin from fresh sunflower heads was optimized using the response surface methodology (RSM). The optimal conditions for the maximum yield of pectin (6.57 ± 0.

Facile fabrication of Cu(II) coordinated chitosan-based magnetic material for effective adsorption of reactive brilliant red from aqueous solution.

In order to effectively remove reactive brilliant red (RBR) in aqueous solution, a novel Cu(II) coordinated chitosan-based magnetic composite (CTS-Cu@SiO@FeO) was prepared. The physicochemical properties of the resultant adsorbent were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), vibrating sample magnetometer (VSM) thermogravimetric (TG) analysis, scanning electron microscopy (SEM) and N adsorption-desorption. The adsorption capacity toward RBR was systematically investigated as a function of contact time, solution pH, initial concentration, ionic strength and temperature.

Three sunflower head pectin (SFHP) with different molecular weights ( = 4.50, 97.23, and 254.

Preparation of a novel chitosan-based magnetic adsorbent CTS@SnO@FeO for effective treatment of dye wastewater.

A novel chitosan-based magnetic composite CTS@SnO@FeO was prepared by water-in-oil emulsification for adsorbing anionic dye RBR in aqueous solution. The physicochemical properties of the obtained material were characterized by FTIR, XRD, VSM, TGA, SEM and N adsorption-desorption. Effects of contact time, solution pH, ionic strength, initial dye concentration and temperature on the adsorption of reactive brilliant red (RBR) were investigated via batch adsorption experiments.

Activation of platelet protease-activated receptor-1 induces epithelial-mesenchymal transition and chemotaxis of colon cancer cell line SW620.

The aim of the present study was to examine the role of protease-activated receptor-1 (PAR1)-stimulated platelet activation in the epithelial-mesenchymal transition (EMT) and migration of colon cancer cells, and to identify the underlying mechanisms. TFLLR-NH2, a PAR1 agonist, was used to activate platelets and the platelet supernatants were used to treat the SW620 colon cancer cell line. Expression of E-cadherin and vimentin on SW620 cells was detected by immunofluorescence and western blotting, and the level of the transforming growth factor β1 (TGF-β1) was measured using ELISA following the activation of platelets by TFLLR-NH2.
