Na-containing manganese-based cathode materials synthesized by sol-gel method for zinc-based rechargeable aqueous battery

Zinc-based rechargeable aqueous batteries are regarded as one of the most safe and inexpensive energy storage systems compared to the conventional rechargeable batteries with organic electrolytes. However, the limited cathode materials and the problem of associated metal ion dissolution restrict its practical application. Herein, the inexpensive novel cathode materials of Na-containing manganese-based composite of Na0.44MnO2 /Mn2O3 and Na2/3Fe1/2Mn1/2O2 are designed and synthesized correspondingly by sol-gel methods combined with freeze-drying technique, and are applied in the zinc-based aqueous batteries for the first time. The secondary particles of Na0.44MnO2/Mn2O3 composite with a cubic box and the molecular sieve configurations are composed of nano primary particles with about 150-300 nm, and the obtained O3-Na2/3Fe1 /2Mn1/2O2 at 850 degrees C (O3-NFM-850) appears to homogenous distribution with 3D solid block structure and platelet-shaped particles, while the spherical core-shell structure of P2 -Na2/3Fe1/2Mn1/2O2 at 850 degrees C (P3-NFM-850-PVA) after dispersed by poly (vinyl alcohol) are linked to each other by amorphous carbon. Finally, the cathode of Na0.44MnO2/Mn2O3 and P3-NFM-850-PVA deliver the reversible capacities of 68.3 mAh g(-1) and 42 mAh g(-1) even after 200 cycles at 0.4 A/g respectively without capacity fading. Compared to the reported Na0.44MnO2, the increased capacity ofNa(0.44)MnO(2)/Mn2O3 composite is attributed to the possible co-insertion of sodium ion and zinc ion for Na0.44MnO2 and the zinc ion insertion for Mn203 as well, indicating the synergetic energy storage for rechargeable hybrid aqueous battery and aqueous zinc ion battery. While the improved cyclic performance of Na2/3Fe1/2Mn1/2O2 is ascribed to the structural stability by Fe-doping and carbon-coating. (C) 2020 Elsevier B.V. All rights reserved.

Thermochemical liquefaction of cattle manure using ethanol as solvent: Effects of temperature on bio-oil yields and chemical compositions

Cattle manure was converted into bio-oil via suband super-critical liquefaction with ethanol as the solvent. The effects of various reaction parameters, including the reaction temperature (T, 180-300 degrees C), solid-liquid ratio (S-1, 5-15%), and solvent filling ratios (S-2, 10-30%) on the yield of bio-oil (OCM) and residue (RCM) from liquefaction of cattle manure were studied. The yield of bio-oil was positively correlated to reaction temperature suggesting higher reaction temperature could promote the fragmentation of the polymers transformed into a liquid oil-rich phase and the maximum OCM relative yield (32.14 +/- 0.19%) was obtained at 300 degrees C. OCM had HHV of 25.63-33.41 MJ/kg and LHV of 23.85-31.39 MJ/ kg, respectively, suggesting their potential for use as a renewable energy to replace fossil energy. The GC-MS analyses demonstrated that the major compounds in OCM were esters, hydrocarbons, alcohols, phenolic compounds, nitrogenous and bromine components, the compositions of OCM was similar to that of biodiesel. The presence of ester compounds in OCM which was attributed to the degradation of cellulose and hemicelluloses. Carbon-normal paraffin gram (C-NP) analysis indicated that C-18 and C-20 species comprised the bulk of the hydrocarbon compounds from OCM. (c) 2020 Elsevier Ltd. All rights reserved.

Indirect coal liquefaction by integrated entrained flow gasification and Rectisol/Fischer-Tropsch processes for producing automobile diesel substitutes

Herein, we describe the design and operation of an indirect coal liquefaction plant with integrated coal water slurry manufacturing, entrained flow gasification, Rectisol, and Fischer-Tropsch processes to produce liquid fuels for vehicles. The above plant contained an entrained flow gasifier (10 t/d test rig) operated using oxygen as a gasifying agent (21 bar, 1100 degrees C) and could stably produce synthesis gas (37.8 vol% H-2, 36.4 vol% CO) at 600 Nm(3)/h. Due to the importance of impurities in synthetic liquid fuel production, more than 99% of H2S contained in synthesis gas was removed by the Rectisol process employing refrigerated methanol. An iron-based catalyst allowed liquid fuels containing wax, light/heavy oil, and alcohol fractions to be obtained by the Fischer-Tropsch process at a rate of 5 barrel per day, with detailed analysis confirming their compliance with various quality standards and thus their suitability for use as automobile diesel after distillation.

4-Methoxybenzylalcohol protects brain microvascular endothelial cells against oxygen-glucose deprivation/reperfusion-induced injury via activation of the PI3K/AKT signaling pathway

Damage to the blood-brain barrier (BBB) during the process of cerebral ischemic injury is a key factor that affects the treatment of this condition. The present study aimed to assess the potential effects of 4-methoxybenzyl alcohol (4-MA) on brain microvascular endothelial cells (bEnd.3) against oxygen-glucose deprivation/reperfusion (OGD/Rep) using an in vitro model that mimics in vivo ischemia/reperfusion injury. In addition, the present study aimed to explore whether this underlying mechanism was associated with the inhibition of pro-inflammatory factors and the activation status of the PI3K/Akt signaling pathway. bEnd.3 cells were subjected to OGD/Rep-induced injury before being treated with 4-MA, following which cell viability, lactate dehydrogenase (LDH) release and levels of nitric oxidase (NO) were detected by colorimetry, pro-inflammatory factors including tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-1 beta and IL-6, were detected by ELISA. The expression levels of occluding and claudin-5were evaluated by immunofluorescence staining. The expression levels of AKT, phosphorylated (p)-Akt, endothelial nitric oxide synthase (eNOS) and p-eNOS were also measured by western blot analysis. After bEnd.3 cells were subjected to OGD/Rep-induced injury, cell viability and NO levels were significantly decreased, whilst LDH leakage and inflammatory factor (TNF-alpha, IL-1 beta and IL-6) levels were significantly increased. Treatment with 4-MA significantly ameliorated cell viability, LDH release and the levels of NO and pro-inflammatory factors TNF-alpha, IL-1 beta and IL-6 as a result of OGD/Rep. Furthermore, treatment with 4-MA upregulated the expression of occludin, claudin-5, Akt and eNOS, in addition to increasing eNOS and AKT phosphorylation in bEnd.3 cells. These results suggest that 4-MA can alleviate OGD/Rep-induced injury in bEnd.3 cells by inhibiting inflammation and by activating the PI3K/AKT signaling pathway as a possible mechanism. Therefore, 4-MA can serve as a potential candidate for treating OGD/Rep-induced injury.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 768-95-6, in my other articles. SDS of cas: 768-95-6.

Novel carbon fibers synthesis, plasma functionalization, and application to polymer composites

PAN copolymers were synthesized via a novel technique, atom transfer radical polymerization (AMP), with the activator generated by electron transfer method (AGET). Carbon fibers (CF) were synthesized at low carbonization temperatures from the novel PAN precursor. Plasma treatment in an oxygen environment at a low pressure of 40 Pa was carried out for 5 minutes on the CF at 100 and 200 W plasma power. The morphology and structure of the CF changed after plasma functionalization, as evident from SEM analysis and Raman spectroscopy. The formation of functional groups like alcohols, carbonyl, and carboxylic on the surface of CF was confirmed with the aid of X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). The wetting test confirmed the higher adhesion of the plasma functionalized CF with the epoxy matrix. Single fiber strength test revealed that plasma functionalized CF retained around 98% of their original tensile strength. Composites were fabricated from the pristine, and the plasma functionalized CF in 1 and 3% by weight with epoxy matrix. The surface-modified CF composites depicted improved tensile (23.4%), tribology (33.62%), and surface hardness (11.4%) properties compared to the composites fabricated from pristine CF.

Multivariate data-based optimization of membrane adsorption process for wastewater treatment: Multi-layer perceptron adaptive neural network versus adaptive neural fuzzy inference system

Application of machine-learning methods to assess the batch adsorption of malachite green (MG) dye on chitosan/polyvinyl alcohol/zeolite imidazolate frameworks membrane adsorbents (CPZ) was investigated in this study. Our previous research results proved the suitability of the CPZ membranes for wastewater decoloring. In the current work, the residence time was combined with the other operational variables i.e., pH, initial dye concentration, and adsorbent dose (AD), to obtain the possible interactions involved in nonequilibrium adsorption. Two well-known soft-computing approaches, multi-layer perceptron adaptive neural network (MLP-ANN) and adaptive neural fuzzy inference system (ANFIS), were selected among different machine learning alternatives and then, comprehensively compared with each other considering reliability and accuracy for a 60 number of runs. The ANFIS structure with nine centers of clusters could predict the adsorption performance better than the ANN approach. Root mean square error (RMSE) and R-square were obtained 0.01822 and 0.9958 for the test data, respectively. The interpretability test resulted a linear trend predicted by the model and disclosed that the maximum value of the removal efficiency (99.5%) could be obtained when the amount of the inputs set to the upper limit. Lastly, the sensitivity analysis uncovered that the residence time has a decisive effect (relevancy factor > 80%) on the removal efficiency. According to the results, ANFIS is an effective and reliable tool to optimize and intensify the membrane adsorption process. (C) 2020 Elsevier Ltd. All rights reserved.

Strong tough hydrogels via the synergy of freeze-casting and salting out

Natural load-bearing materials such as tendons have a high water content of about 70 per cent but are still strong and tough, even when used for over one million cycles per year, owing to the hierarchical assembly of anisotropic structures across multiple length scales(1). Synthetic hydrogels have been created using methods such as electro-spinning(2), extrusion(3), compositing(4,5), freeze-casting(6,7), self-assembly(8) and mechanical stretching(9,10) for improved mechanical performance. However, in contrast to tendons, many hydrogels with the same high water content do not show high strength, toughness or fatigue resistance. Here we present a strategy to produce a multi-length-scale hierarchical hydrogel architecture using a freezing-assisted salting-out treatment. The produced poly(vinyl alcohol) hydrogels are highly anisotropic, comprising micrometre-scale honeycomb-like pore walls, which in turn comprise interconnected nanofibril meshes. These hydrogels have a water content of 70-95 per cent and properties that compare favourably to those of other tough hydrogels and even natural tendons; for example, an ultimate stress of 23.5 +/- 2.7 megapascals, strain levels of 2,900 +/- 450 per cent, toughness of 210 +/- 13 megajoules per cubic metre, fracture energy of 170 +/- 8 kilojoules per square metre and a fatigue threshold of 10.5 +/- 1.3 kilojoules per square metre. The presented strategy is generalizable to other polymers, and could expand the applicability of structural hydrogels to conditions involving more demanding mechanical loading. A strategy that combines freeze-casting and salting-out treatments produces strong, tough, stretchable and fatigue-resistant poly(vinyl alcohol) hydrogels.

Microalgal secondary metabolites: effect of climatic variables, seasons, and photocycles on the biogeneration of volatile organic compounds (VOCs)

Microalgae produce many metabolites with diversified structures that play important roles in their development. This work evaluated the effects of different climatic variables, seasons, and light/dark phases in the production of volatile organic compounds by Scenedesmus obliquus CPCC05, focusing on the simulation of climatic variables (average temperature, maximum light intensity, and light hours per day) of the extreme geographical positions of Brazil based on tropical Am, tropical Aw, and subtropical Cfa climates found in Joao Pessoa-PB, Rio Branco-AC, Boa Vista-RR, and Rio Grande-RS, in summer and winter seasons. For the best condition in this first step, the light/dark phases together with the residence time of the culture were evaluated. A total of 45 compounds were identified in all conditions studied. The main volatile groups found were hydrocarbons, aldehydes, ketones, alcohols, and terpenes identified in both geographic locations. Among these, hydrocarbons were the main biomarkers of the subtropical Cfa climate, while the ketone group was produced mainly in warmer climates, such as the Aw tropical climate. In the experiments of light/dark phases, a total of 34 compounds were identified. 2-Pentenol and decanal were only produced in the light phase, while 1-pentanol and 2-ethyl hexanol were only found in the dark phase. The main volatile compound found was 3-methylbutanol reaching a total area abundance of 14.10%. The major compounds detected during the cultures were originated and derived from the terpenoid pathways, fatty acids, and amino acid derivates.

Structure and functionality of oat protein extracted by choline chloride-dihydric alcohol deep eutectic solvent and its water binary mixtures

This research reports an eco-friendly oat protein extraction method using choline chloride (ChCl)-butanediol deep eutectic solvents (DESs) and DES/water binary mixtures. Eighteen formulas consisting of ChCl with butanediol isomer (1,2-butanediol, 1,4-butanediol, or 2, 3-butanediol) in the absence or presence of water at different molar ratio were examined for the synthesis of DESs and binary mixtures. We found that 6 formulae can be fabricated at a ChCl-butanediol molar ratio of 1:3 independent of water presence, and that they had better oat extraction performance with 90 min extraction at 80 degrees C. Under the optimal conditions, we further assessed the impact of butanediol isomers and water addition on the structure characteristics and functionalities of extracted oat protein. The results suggested that oat protein extracted by ChCl-1,4-butanediol/water binary mixture had highest protein content, solubility, foaming capacity and stability. Our pilot findings provide crucial support to our hypothesis that the isomer of hydrogen bond donor is critically involved in the properties of oat protein the DES and the binary mixtures extracted, which pave the way for the future application of DES in protein extraction.
