Biomimetic superhydrophobic membrane with multi-scale porous microstructure for waterproof and breathable application

The multifunctional membranes with superior waterproofness and breathability have been extensively used in high-end wearable protection, desalination, and the aerospace industry. A multi-layered, biomimetic and superhydmphobic membrane is designed via a facile two-step strategy of phase-conversion and electrospraying. The homogeneous reticular porous microstructure with a stellate spherulite surface formed by introducing sodium chloride (NaCl) during the phase-conversion process provides an effective vapor-permeable channel for the membrane. Zirconium carbide (ZrC)/silica (SiO2) as two-component inorganic powders with different particle sizes can construct bio-inspired, hierarchical, and superhydrophobic layers. Simultaneously, the synergistic interactions between the components can preferably inspire the photo-to-thermal conversion properties of membranes, further accelerating the efficient transport of water vapor. The ultrathin hierarchical nanoporous composite membrane exhibits the excellent breathability of 11.9 kg m(-2) d(-1) and decent waterproofness of 60.71 kPa. An ultrahigh WCA of up to 167.3 degrees gives a stabilized superhydrophobic surface to the high moisture-permeable membrane while possessed robust reusable self-cleaning and photo-to-thermal properties. Furthermore, the superior performances with the tremendous potential for application prospects in various fields.

Promotive role of microRNA-150 in hippocampal neurons apoptosis in vascular dementia model rats

Cognitive impairment is one of the primary features of vascular dementia (VD). However, the specific mechanism underlying the regulation of cognition function in VD is not completely understood. The present study aimed to explore the effects of microRNA (miR)-150 on VD. To determine the effects of miR-150 on cognitive function and hippocampal neurons in VD model rats, rats were subjected to intracerebroventricular injections of miR-150 antagomiR. The Morris water maze test results demonstrated that spatial learning ability was impaired in VD model rats compared with control rats. Moreover, compared with antagomiR negative control (NC), miR-150 antagomiR alleviated cognitive impairment and enhanced memory ability in VD model rats. The triphenyltetrazolium chloride, Nissl staining and immunohistochemistry results further demonstrated that miR-150 knockdown improved the activity of hippocampal neurons in VD model rats compared with the antagomiR NC group. To validate the role of miR-150 in neurons in vitro, the PC12 cell line was used. The flow cytometry and Hoechst 33342/PI double staining results indicated that miR-150 overexpression significantly increased cell apoptosis compared with the mimic NC group. Moreover, the dual-luciferase reporter gene assay results indicated that miR-150 targeted HOXA1 and negatively regulated HOXA1 expression. Therefore, the present study indicated that miR-150 knockdown ameliorated VD symptoms by upregulating HOXA1 expression in vivo and in vitro.

A Zn-Ce Redox Flow Battery with Ethaline Deep Eutectic Solvent

Compared with conventional aqueous and ionic liquid electrolytes, deep eutectic solvent (DES) are considered as electrolyte for redox flow batteries because they have a wider electrochemical window and relatively low price. In this study, Ce-IV/Ce-III and Zn-II/Zn redox couples are used as the positive and negative active materials, respectively, in an electrolyte consisting of choline chloride ethylene glycol (ethaline). The structure of Ce-III in the positive electrolyte is inferred through spectrum detection. Ce-IV/Ce-III and Zn-II/Zn redox couples show a stable potential difference of 2.2 V (vs. Ag) through cyclic voltammetry. The charge and discharge performance of battery was tested at different current densities. In addition, battery performance was evaluated at different temperatures and concentrations of cerium in the electrolyte. Consequently, at a current density of 0.5 mA cm(-2) at room temperature and using 1.0 m Ce-III, the battery performance reaches the best coulombic efficiency of 84 %.

Ni-Mo-Cr alloy corrosion in molten NaCl-KCl-MgCl2 salt and vapour

The corrosion behaviours of Ni-Mo-Cr alloy samples immersed in NaCl-KCl-MgCl2 salt and vapour were investigated at 700.0 degrees C for 100 h. The surface layer of the corroded alloy in liquid molten salt exhibited slight Cr depletion. The alloy formed a loose double layer of Cr, Mo and Mg oxide in the vapour. The oxidation with Mg chloride in the salt vapour accelerated corrosion of the sample, and its Cr-depleted depth was nearly twice that of a sample immersed in liquid molten salt. The corrosion of an alloy by salt vapour must not be neglected in practical applications.

Paper-Based Enzyme Biosensor for One-Step Detection of Hypoxanthine in Fresh and Degraded Fish

Food freshness monitoring, which can reflect the quality of the product at the time of use, remains a great challenge for consumers and the food industry. Herein, we report the development of a cost-effective enzyme-based paper biosensor, which can monitor fish freshness and predict spoilage. The biosensor measures the release of hypoxanthine (HX), an indicator of meat and fish degradation, using the enzymatic conversion of HX by xanthine oxidase (XOD). We demonstrate that the entrapment of XOD and an organic dye, nitro blue tetrazolium chloride (NBT), within a sol-gel biohybrid enables their stabilization on paper and promotes the enzymatic reaction with further retention of the reaction products within the cellulosic network . Linearity in the micromolar concentration range with a detection limit of 3.7 mu M for HX is obtained. The biosensor has high selectivity toward HX and is manufactured in few steps from inexpensive widely available materials. The applicability of the biosensor is demonstrated by following fish degradation over time and measuring HX concentrations ranging from 117 (+/- 9) to 198 (+/- 5) mu M within 24 h of degradation, at levels that are comparable with those measured by a commercial enzymatic kit for HX detection. As compared to the commercial kit, our biosensors are more cost-effective, do not require addition of exogenous reagents and are portable, having all of the reagents needed for analysis embedded within the sensing platform. This proof-of-concept work demonstrates that the paper-based HX biosensor has potential as a robust reagentless device for real-time monitoring of food freshness and for other applications in which HX plays an important role.

Construction of highly efficient ion channel within anion exchange membrane based on interpenetrating polymer network for H-2/Air (CO2-free) alkaline fuel cell

Interpenetrating polymer network anion exchange membrane (IPN AEM) consists of cross-linked quaternized poly (vinylbenzyl chloride) and cross-linked poly (vinyl alcohol) is synthesized in this work. Electron microscope clearly reveals the IPN structure, and with this structural design, a highly efficient ion channel within IPN AEMs is constructed. This specially designed structure leads to high hydroxide (OH-) conductivity (e.g., 141.7 mS cm(-1) at 80 degrees C) at a moderate ion exchange capacity (IEC) of 1.61 mmol g(-1), and a remarkable peak power density of 0.64 W cm(-2) with non-noble metal oxygen reduction reaction (ORR) catalyst in H-2/Air (CO2-free) anion exchange membrane fuel cells (AEMFCs) test.

Effects of thiosulfate and dissolved oxygen on crevice corrosion of Alloy 690 in high-temperature chloride solution

The crevice corrosion behavior of Alloy 690 was investigated in high-temperature chloride solution containing different concentrations of thiosulfate (S2O32-) and dissolved oxygen (DO). The S2O32- inhibited corrosion of Alloy 690 through consuming oxygen in aerated chloride solution. In deaerated chloride solution, the S2O32- was reduced to S degrees and S-2 and subsequently incorporated into the oxide films, which promoted the pitting corrosion at locations of both TiN inclusions and matrix inside the crevice during the crevice corrosion as well as influenced the composition and thickness of the oxide films. The effect mechanisms of S2O32- and DO on crevice corrosion in high-temperature chloride solution are discussed.

One-pot ball-milling preparation of cetylpyridinium chloride/alpha-zirconium phosphate composite for simultaneous detection of ascorbic acid and dopamine

In this study, we report a rapid and facile synthesis of cetylpyridinium chloride (CPC) intercalated alpha-zirconium phosphate (alpha-ZrP) by a one-pot ball-milling method. The obtained intercalation composite were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA). The effect of milling time on the intercalation behavior was investigated and CPC can be successfully inserted into the gallery of alpha-ZrP after 2 h of grinding. The as-prepared CPC/alpha-ZrP composite was used for the modification of glass carbon electrode (GCE) and simultaneous detection of ascorbic acid (AA) and dopamine (DA) via cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. AA and DA exhibited two well-resolved oxidation peaks on the CPC/alpha-ZrP modified electrode with a potential difference of 307 mV. The calibration curves obtained are linear for the currents versus AA and DA concentrations in the range 40-1500 mu M and 13-520 mu M, with the detection limits (S/N = 3) are 10 mu M and 3.3 mu M, respectively. The modified electrode could provide a new platform for the determination of AA and DA in terms of excellent reproducibility and stability. (C) 2020 Elsevier B.V. All rights reserved.

Microplastic abundance, distribution, and composition in the surface water and sediments of the Yangtze River along Chongqing City, China

Purpose Microplastics are considered emerging pollutants and already currently present in measurable quantities in aquatic ecosystems. However, information on the current status of microplastic pollution in the upper Yangtze River, the most important water body in China, is insufficient. In the present study, the abundance and distribution of microplastics in the surface water and sediments were investigated to obtain the characteristics of microplastic pollution in Yangtze River along Chongqing City. Materials and methods Ten sampling sites along Yangtze River in the Chongqing urban area were selected to collect surface water and sediment samples. Abundance and morphological characteristics of microplastics were determined by counting using a digital stereo microscope. Micro-Fourier transform-infrared spectroscopy (mu-FTIR) analysis was used to identify polymer type of the microplastics. Results and discussion The abundance of microplastics ranged within 46.7-204 n L-1 and 100-583 n kg(-1) dw (dry weight) in the surface water and sediment samples, respectively. Fibers and films were dominant in most of samples, and the average proportion of fibers reached 74.3% in surface water. Whether in surface water or sediments, most of the microplastics were less than 0.7 mm in size, and the average proportion of microplastics with a size of less than 0.3 mm reached 62.6% in the sediment samples. Moreover, fibrous and small were the primary characteristics of the microplastics. Polypropylene, polyvinyl chloride, high-density polyethylene, polyester, and wool fibers were identified in the surface water samples. Conclusion The Yangtze River along Chongqing City is contaminated by microplastic, like many urban rivers. Anthropogenic activities, including sewage treatment effluents, might be the main sources of microplastic pollution in Yangtze River (Chongqing urban section). This study reveals the contamination and characteristics of microplastics in the Yangtze River along Chongqing and supplies important data for further research on microplastics in Yangtze River’s basin.
