ABSTRACT The augmentation of chitosan's (CS) antioxidative and antibacterial properties via grafting with phenolic acids constitutes a significant method for expanding the utility chitosan. In this investigation, four (gallic acid, GA; protocatechuic PCA; hydroxybenzoic HA; salicylic SA) were conjugated CS utilizing carbodiimide (EDC)‐mediated grafting. resultant acid‐CS graft copolymers underwent characterization employing infrared spectroscopy, x‐ray diffraction, thermogravimetric...
Four deep eutectic solvents (DESs), namely, glycerol/chlorocholine (glycerol/ChCl), urea/ChCl, citric acid/ChCl, and oxalic were synthesized their performance in the dissolution of cellulose was studied. The results showed that melting point DESs varied with proportion hydrogen bond donor material. viscosity changed considerably change temperature; as temperature increased, decreased electrical conductivity increased. Oxalic acid/ChCl exhibited best effects on cellulose. microscopic...
The synthesis and characterization of a degradable version poly(acrylic acid), poly(glyceric acid carbonate), are reported. Specifically, atactic isotactic poly(benzyl glycidate carbonate)s obtained via the ring-opening copolymerization rac-/(R)-benzyl with CO2 using bifunctional rac-/(S,S)-cobalt salen catalyst in high carbonate linkage selectivity (>99%) polymer/cyclic (∼90%). Atactic carbonate) is an amorphous material Tg (glass transition temperature) 44 °C, while its counterpart...
The separation of cellulose, hemicellulose, and lignin components using deep eutectic solvent, which is a green to obtain corresponding chemicals can realize the effective high-value utilization these at low cost. In this study, we used waste biomass sugarcane bagasse as raw material, choline chloride hydrogen bond acceptor, lactic acid donor synthesize solvent chloride/lactic (L-DES) treated pretreated by alkali or hydrothermal methods separate lignin. addition, comparatively studied effect...
Many achievements have been made on the research of composite polyurethane foams to improve their structure and mechanical properties, widely utilized in building insulation furniture. In this work, rigid (RPUFs) with addition different fillers (nano-SiO2, peanut shell, pine bark) were prepared through one-step method. The effects inorganic nano-SiO2 organic biomass foam properties evaluated by means physical chemical characterization. characterization results indicate that compressive...
An improved stochastic reconstruction method for a gas diffusion layer (GDL) of proton exchange membrane fuel cell is developed to promote the accuracy in evaluating effective diffusivity. Carbon fibers are generated using algorithm within representative element volume. Structural characteristics, porosity distribution and fiber orientation set as constraints reconstructing microstructure. Morphological opening image processing with structuring employed add binder polytetrafluoroethylene...
Abstract For second‐generation (2G) bioethanol refineries, the feedstock supply is one of important parameters in terms cost and consistency. Biorefineries are most cases designed for a specific type feedstock. some biorefineries, use multiple feedstocks an option, but how would such perform when used process optimized feedstock? There no “one‐size‐fits‐all” processing package, due to variations composition structure different types, size commercial only minor adjustments practically...
ABSTRACT Magnesium hydroxide (Mg(OH) 2 , MH) exhibits excellent flame‐retardant properties, but its poor interface compatibility with the resin matrices limits application. In this study, β‐cyclodextrin (CD) was employed to coat MH, successfully preparing a microencapsulated CD‐MH flame retardant. Various mass ratios of m @FA n /PVC composites were further prepared. The maximum specific optical density (pkmax) 0.2 0.1 decreased 7.80%, total smoke release (THR) reduced by 26%, and residual...
Abstract Perfluorosulfonated ionomer (PFSI) was synthesized and PFSI membranes were prepared via a solution‐cast method annealed at different temperatures from 150 to 230°C. The annealing effect on water content, proton conductivity, methanol permeability reported discussed. X‐ray diffraction small angle scattering used test the structure of membranes. It found that increased conductivity because heat‐treatment helped free sulfonic groups buried in polymer segments form more organized ionic...
In this paper, a two-phase system, formed by oxalic acid/choline chloride-based deep eutectic solvent (DES) and chosen extractants, was used as dissolution–reaction–separation metal chloride catalyst to study the degradation of cellulose produce 5-hydroxymethylfurfural (5-HMF) glucose. The effects amount organic reaction temperature on product yield, repeated recycling DES, comparison between system homogeneous mechanism 5-HMF were investigated. results show that ethyl n-butyrate has best...
The strain-controlled cyclic deformation behaviour of Mg-9Gd-4Y-2Zn-0.5Zr with different structures was investigated. Alloys were prepared by solution, extrusion and pre-ageing extrusion, the microstructures before after fatigue tests characterized. Experimental results indicated that bimodal structure owned better performance in test, which attributed to higher yield strength. For equiaxed structure, hardening induced stress concentration until failure. Stable persistent softening played an...
