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.

Bright and persistent green and red light-emitting fine fibers: A potential candidate for smart textiles

The properties of smart light-emitting textile/fabric with a persistent afterglow can be beneficial for use in anticounterfeiting, night surveillance, and security trooping among other potential applications. Keeping this in mind, this work is a step forward in designing bright green and red emitting poly vinyl alcohol (PVA) fine fibers. We first synthesized green emitting Zn2GeO4:Mn2+ (ZGOM) and red emitting ZnGa2O4:Cr3+ (ZGOC) nanoparticles using a hydrothermal process. Field Emission Scanning Electron Microscope (FESEM) images depicted the formation of nanomds and sub-10 nm nanoparticles for ZGOM and ZGOC, respectively. These nanoparticles were mixed in a PVA solution and spun into fiber using the Forcespinning (R) technology. FESEM images of the fiber samples show the presence of long, bead-free, defect-free, smooth surfaces with the diameters ranging from 200 nm to 1.2 mu m depending on selected processing parameters; a fiber system was selected considering fiber output and fiber diameter, the selected system had fibers with average diameter of 900 nm for both ZGOM and ZGOC encapsulated PVA fine fibers (MG-PF and CR-PF). Another favorable property was that the thermal stability of the PVA fine fibers was not affected by the nanoparticles. Both MF-PF and CR-PF fine fibers depicted a bright green and red luminescence, respectively, under UV excitation. The fiber can easily accommodate loading up to 1.0% weight without doing any kind of fluorescence quenching. MG-PF fiber displayed a bright and substantial green persistence luminescence up to 500 s. In the case of CR-PF there is a quenching of trap states and therefore intrinsic red persistence luminescence is not retained beyond 100 s. We believe such green fiber if smartly woven in any kind of textile materials/fabric can be an efficient solution to deal with cloth counterfeiting and night surveillance.

Mitigation of nivalenol using alcoholic fermentation and magnetic field application

This study aimed at evaluating mitigation of nivalenol (NIV) in alcoholic fermentation with magnetic field application (MF). Mitigation was related to both the glutathione (GSH) redox molecule and the enzyme peroxidase (PO), which were synthesized by Saccharomyces cerevisiae US-05. Conditions under evaluation were NIV (0.2 mu g mL(-1)), MF application (35 mT) and simultaneous use of mycotoxin and MF. The GSH content and the PO activity were increased when the culture contained NIV and the alcohol profile was altered after 48 h of fermentation. At the end of the alcoholic fermentation, NIV was mitigated by 56.5%. Therefore, this process is a promising method to reduce contamination by NIV, although the mycotoxin affects the chemical characteristics of the final product.

Strategies to utilize naturally occurring protein architectures as nanovehicles for hydrophobic nutraceuticals

The development of protein-based nanovehicles to improve water solubility, stability and bioavailability of hydrophobic or poorly soluble nutraceuticals has become a subject of fast increasing interest in the field. This review mainly presents the state-of-art knowledge about the utilization of naturally occurring nanostructured protein architectures (casein micelles, ferritin and legume oligomeric globulins) as nanovehicles for hydrophobic nutraceuticals or drugs, through a disassembly and reassembly strategy. First, the composition and structural features of these three naturally occurring architectures are briefly summarized. Then, many strategies and techniques to mediate the disassembly and reassembly of these naturally occurring architectures are comprehensively reviewed, including pH-, urea-, alcohol-, high pressure-, and heat-mediated disassembly and reassembly (or dissociation and reassociation). Last, reassembled casein micelles, ferritin (or apoferritin) and legume oligomeric protein nanoparticles are demonstrated to perform as outstanding nanovehicles for improving water dispersion, stability and bioactivities of many nutraceuticals or drugs. Due to the rapidly increasing consumer interests for health-benefiting foods, this review is of importance for the development of a kind of outstanding nanovehicles for nutraceuticals with a great potential to be applied in functional foods or drug formulations.

Destabilization mechanism of (W-1+W-2 )/O reverse Janus emulsions

Hypothesis: Reverse Janus emulsion, with droplets composed by two rooms of water phases, is a novel multiple emulsion attributed to excellent integration capability and biocompatibility. However, significant instability compared with normal Janus emulsions renders the stability issue of great importance. Moreover, the ultra-low aqueous-aqueous inner interfacial tension, the anisotropic nature of the droplets with distinct lobe composition, and the random orientation in the continuous phase endow the complicated and various demulsification mechanisms. Experiments: Reverse Janus emulsion of (W-1+W-2)/O, employing typical salt-alcohol aqueous two-phase system (ATPS) as inner phases, is prepared in batch scale by conventional one-step vortex mixing. The demulsification process is detected by multiple light scattering technique, which provides real-time, in-situ, and quantitative information of emulsion evolution. Moreover, the fusion pattern of the anisotropic droplets is illustrated by the combination with light microscopy and size distribution measurement. Findings: Coalescence and sedimentation are found to be two main demulsification processes. Two salt body lobes of the snowman shaped Janus droplets combine first resulting in an intermediate Cerberus topology with two alcohol heads on one salt body. Subsequently, two head lobes coalesce resulting in a larger Janus droplet. Ultimately, the Gibbs free energy leads to a final state with three separated liquids. In addition, the variation in lobe viscosity, density, and properties of interfacial film greatly affect the demulsification rate and fusion pattern. A critical alcohol/surfactant mass ratio of 2 is found, beyond which a completely different fusion pattern occurs. Two alcohol body lobes combine first resulting in an intermediate Cerberus topology with two salt heads on one alcohol body. Subsequently, two head lobes coalesce resulting in a larger Janus droplet. The findings are instructive in the stability of aqueous based multiple emulsions with advanced morphologies and meanwhile, promote the future application of this novel emulsion in food science, pharmacy, and biomimetic compartmentalization.

Construction of hierarchical photocatalysts by growing ZnIn2S4 nanosheets on Prussian blue analogue-derived bimetallic sulfides for solar co-production of H-2 and organic chemicals

Exploring highly efficient bifunctional photocatalysts for simultaneous H-2 evolution and organic chemical production in pure water represents a green route for sustainable solar energy storage and conversion. Herein, a facile strategy was explored for preparing a hierarchical porous heterostructure of Fe4Ni5S8@ZnIn2S4(FNS@ZIS) by the in situ growth of ZIS nanosheets on Prussian blue analogue (PBA)-derived bimetallic FNS sulfides. A series of FNS@ZIS hierarchical structures were facilely prepared by adjusting the loading amount (n%) of FNS (n = 19, 26, and 32 for FNS@ZIS-1-3). These structures can efficiently drive the solar co-production of H2 and organic chemicals. The optimal co-production was achieved with FNS@ZIS-2, affording a H-2 evolution rate of 10465 mu mol.g(-1).h(-1), along with high selectivity for the oxidation of benzyl alcohol to benzaldehyde (>99.9%). The performance was 22 and 31 times higher than that of FNS and ZIS, respectively, and even superior to the state-of-the-art results achieved using various sacrificial agents. Further mechanistic study indicated that the unique hierarchical core/shell architecture can facilitate interfacial charge separation, afford bimetallic synergy, abundant active sites and excellent photostability. This work highlights a simple and efficient method for preparing porous multimetallic hierarchical structures for the solar co-production of organic chemicals and H-2 fuel.

Determination and utilization of optimal diesel/n-butanol/biogas derivation for small utility dual fuel diesel engine

Aggregating pollution along with exhausting fossil fuels throughout the world has enforced the inventors to explore for an alternative fuel that can be utilized in diesel engines. Presently, investigators and professionals have originated that biodiesel in association with higher alcohols and gaseous fuel can be an alternative for the current circumstances. Anterior examinations have rendered that biodiesel and higher alcohol along with gaseous fuels can support in upgrading the performance and denigrating detrimental exhaust emanations in a diesel engine. This research aimed to investigate the impacts of engine load, n-butanol concentration, and biogas quantity on emissions and performance characteristics of a small utility compression ignition engine. The different engine load (20-100% of brake power), n-butanol concentration (0-20%) and biogas flow rate (0.5-2 kg/h) were used as input variables. The multi-criteria decision analysis based on response surface method techniques was employed to find the optimal values of engine working conditions fuelled with diesel/n-butanol/biogas fuel blends. In the optimization process, five objective functions (BTE, NOX, CO, UHC, and soot) were considered to be optimized based on the defined criteria. The addition of n-butanol in diesel has shown a favourable impact on biogas operated dual-fuel engine in terms of performance and emissions characteristics. The approach of desirability was applied to obtain the best operating conditions of the engine. The optimum value of engine load, n-butanol concentration, and biogas flow rate were found as 78.89%, 20%, and 1.37 kg/h, respectively. At this condition, the optimal value of BTE, UHC, CO, NOX, and smoke emissions were found to be 19.19%, 0.36g/kWh, 0.04%, 14.51g/kWh, and 22.32%, respectively. A high desirability value of 0.77 was obtained for the suggested condition, showing the efficiency of the derived models for response parameters.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 156-87-6 is helpful to your research. Category: alcohols-buliding-blocks.

The expression profiles of acid-stable alpha-amylase and acid-labile alpha-amylase of Aspergillus luchuensis mut. Kawachii effect on the microstructure of koji and alcohol fermentation

We investigated the contribution of the complex expressions of two alpha-amylases, namely acid-stable alpha-amylase (AS-amylase) and acid-labile alpha-amylase (AL-amylase), from Aspergillus kawachii to the microstructure of koji and the brewing. AL-amylase was found to be the primary contributor to the decomposition of starch in the early stage of koji making. From the middle stage, both alpha-amylases decomposed the starch in a coordinated manner, and at the final stage, acid-stable alpha-amylase and glucoamylase decomposed the starch granules. Characterization of koji prepared by the single disruptions of AS-amylase or AL-amylase genes, double disruption of both alpha-amylase genes, and triple disruption of two alpha-amylase and glucoamylase genes in A. kawachii cells indicated that both alpha-amylases can work in a synergistic manner to decompose starches during koji making. AL-amylase was found, for the first time, to play an important role in starch decomposition in koji. The speed of alcohol fermentation and ester contents of the fermented mash were higher the mash prepared the control strain, followed by single, double, and triple disruptants. These results indicate that the microstructure of koji plays a role in promoting alcohol fermentation and flavor development.

Calcium-induced-gel properties for low methoxyl pectin in the presence of different sugar alcohols

The gel behavior of low methoxyl pectin (LMP), de-esterified by high hydrostatic pressure (HHP)-assisted enzymatic method, was comparatively investigated in the presence of different sugar alcohols (erythritol, xylitol and sorbitol). Results showed that both sugar alcohol type and concentration had significant effects on LMP gelation. Gel strength, elasticity, and storage modulus G’ decreased with increasing sugar alcohol concentration, but erythritol-gels always showed the highest value, and sorbitol-gels the lowest at the same sugar alcohol concentration. All LMP gels had good water holding capacity (>97%) when the sugar alcohols concentration was less than 20% (w/v). Moreover, micro-rheology properties revealed that erythritol-gels with better elasticity also formed faster, showing higher gel point. These differences might be mainly due to the combination of sugar alcohols with calcium and pectin inhibiting the interaction between pectin and calcium. In addition, the competition for water between pectin and sugar alcohol also played a certain role. All these results indicated that erythritol-gels had more potential application in low-calorie foods due to its superior gel properties and lower calories.

Effect of Saccharomyces cerevisiae and Schizosaccharomyces pombe strains on chemical composition and sensory quality of ciders made from Finnish apple cultivars

Composition of volatile compounds and concentrations of sugars and organic acids were studied in apple ciders produced with Saccharomyces cerevisiae and Schizosaccharomyces pombe yeasts using eleven different Finnish apple cultivars. Moreover, sensory quality of selected ciders was studied using check-all-that-apply test with untrained panelists. Seventy-seven volatile compounds were detected in the samples using HS-SPME-GC-MS. In general, the ciders had higher concentrations of higher alcohols, aldehydes, and acetals whereas the juices contained higher contents of C6-alcohols. Simultaneously, fermentation using S. pombe resulted in lower concentrations of malic acid, ethyl pentanoate, ethyl hexanoate, and volatile acids and higher concentrations of residual sugars compared to S. cerevisiae. Ciders made using S. cerevisiae were characterized as ‘alcoholic’ and `yeasty’ while S. pombe ciders were more frequently described as ‘sweet’, ‘honey-like’, and less rated as sour. Besides the strong effect by the yeasts, apple cultivars had significant effects on the compositional and sensorial properties of apple ciders.
