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.

Assimilable nitrogen reduces the higher alcohols content of huangjiu

Yeast assimilable nitrogen (YAN) sources play an important role in the formation of higher alcohols in wine. In this study, the types and amounts of YAN sources and the genes that regulate the synthesis of higher alcohols in a yeast used for huangjiu brewing, Saccharomyces cerevisiae HJ, were assessed for the first time. Quantitative realtime PCR experiments demonstrated that S. cerevisiae HJ genes controlling the production of higher alcohols were expressed at significantly different levels during different growth stages and at different YAN levels, indicating that YAN significantly impacts the total higher alcohols concentration of huangjiu. Ammonium salts especially NH4Cl showed greater effect in reducing the content of higher alcohols than amino acids or urea. After optimization, the addition of NH4Cl (200 mg/L) most effectively reduced the content of higher alcohols at the end of fermentation with little effect on the cell growth rate, final cell density and ethanol concentration. Total higher alcohols decreased by 39%, while the concentrations of isobutanol, isoamylol and 2-phenylethanol decreased by 47%, 28%, and 44%, respectively. The addition of NH4Cl promoted the formation of esters and enriched the amino acids in huangjiu. This study provides a new insight to control the quality of huangjiu, especially the content of higher alcohols based on the strategy of adding NH4Cl.

Progress in alcohol-gasoline blends and their effects on the performance and emissions in SI engines under different operating conditions

Bio-alcohol has the potential to be used as an alternative to fossil fuels to reduce the total exhaust emissions from spark-ignition engines. This paper reviewed the most recent experimental studies on fundamental effects of performance, emissions and some combustion characteristics in SI engines. It also provides a guideline for suitable ethanol-gasoline and methanol-gasoline blend rates. Investigations were performed on different engines, operating conditions and rates of fuel blends with varying engine speeds. Most of the results showed that ethanol-gasoline has more benefits compared to methanol-gasoline in terms of exhaust emissions, engine power, and torque output, especially at low engine speed. The small differences in properties between ethanol-gasoline and methanol-gasoline blends are enough to create a significant change in the combustion system. These effects lead to behavioural mechanisms which are not easy to analyze or understand, sometimes make it difficult to identify the fundamentals of how ethanol or methanol affects emissions.

Design of polymeric core-shell carriers for combination therapies

Particle engineering for co-delivery of drugs has the potential to combine multiple drugs with different pharmaceutical mechanisms within the same carrier, increasing the therapeutic efficiency while improving patient compliance. This work proposes a novel approach for producing polymer-polymer core-shell microparticles by multi-step processing of emulsion and spray drying. The particle core was obtained by an oil-in-water emulsion of poly(e-caprolactone) (PCL) loaded with curcumin (CM), followed by the resuspension in poly(vinyl alcohol) (PVA) containing ciprofloxacin (CPx) forming the shell layer by spray-drying. The obtained core-shell particles showed an average size of 3.8 +/- 1.2 mu m, which is a suitable size for inhalation therapies. The spatial distribution of the drugs was studied using synchrotron-based macro attenuated total reflection Fourier transform infrared (macro ATR-FTIR) microspectroscopy to map the chemical distribution of the components within the particles and supported the presence of CM and CPx in the core and shell layers, respectively. The formation of the core-shell structure was further supported by the differences in the release profile of CM from these particles, when compared to the release profile observed for the single particle structure (PCL-CM). Both empty and drug-loaded carriers (up to 100 mu g.mL(-1)) showed no cytotoxic effects on A549 cells while exhibiting the antibacterial activity of CPx against Gram-positive and Gram-negative bacteria. These polymer core-shell microparticles provide a promising route for the combination and sequential drug release therapies, with the potential to be used in inhalation therapies.
