Abstract The increasing deforestation with an alarming rate is the prime cause of upsetting the balance in the natural ecosystem and the livelihood of local communities. Sustainable forest management and reforestation efforts can equilibrium this destruction and maintain the protected areas. In this regard, soil management strategies for reforestation of the degraded forest land can be helpful. In this review, the potential of using biochar, a solid carbon rich product of biomass thermochemical conversion, as a soil amendment in forest soils has been discussed. The production procedures of biochar, availability of feedstocks and the biochar properties are discussed using the existing… More >

Abstract Biocompatible and high content grafted carboxymethyl cellulose-gpoly(acrylic acid) powder was successfully synthesized in an aqueous system, and used as adsorbents for the removal of Cu(II) in aqueous solution. The copolymer was characterized by FT-IR and SEM techniques. Graft copolymerization introduced a large number of carboxyl groups in the polymer and caused the micro-surface of the material to be porous. The fundamental adsorption behaviors of the material were studied. The adsorption kinetics was well fitted with pseudo-second order equation, while the adsorption isotherm preferred to be described the Langmuir equation. The maximum adsorption capacity obtained from the Langmuir model was 154.32… More >

Abstract A water-soluble lubricant additive (RSOPE) was prepared by esterification reaction using fatty acid from rubber seed oil. The RSOPE was added into water-ethylene glycol (W-EG) solution as lubricant additive. Dispersion stability and rheological properties were investigated. We used a four-ball tribotester to assess the lubrication performance of W-EG based fluid with the RSOPE additive. The stainless-steel surface was analyzed using scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Good dispersion stability was observed in the RSOPE/W-EG solutions. Furthermore, nonNewtonian fluid behavior at low shear rates and Newtonian fluid behavior at high shear rates was exhibited. The addition of RSOPE… More >

Abstract Plant components are an inexhaustible source for the construction of bio-based materials. Here we report, for the first time, the elaboration of biobased cellulose nanocrystals (CNC)/xyloglucan (XG) hydrogels. XG is a hemicellulose displaying a great affinity for cellulose surface and can be thus irreversibly adsorbed on CNC. Properties of the hydrogels were investigated by varying the molar mass of XG either by enzymatic treatment with Endoglucanase (EG2) or physical fractionation by ultrasound (US). Fractions were characterised by high-performance size exclusion chromatography (HPSEC) and their monosacchari decompositions were determined. Three fractions with high, average and small molar mass, (800, 300 and… More >

Abstract Introduction of the strategy of anhydrous calcium carbonate protection incorporated with the drop by drop reaction, high-purity 1-butyl-3-methylimidazolium chloride ([Bmim] Cl) was prepared at reaction temperature of 80°C for only 10 h. Cellulose samples from different biomass sources (with different degree of polymerization characteristic) could be rapidly (no more than 10 minutes) and completely dissolved in the [Bmim] Cl using a microwave-assisted ionothermal route. Homogeneous cellulosic regenerates with high degree of polymerization and thermal stability characteristics were obtained through a coagulation process in water. Furthermore, the dissolved celluloses were readily regenerated into solid products such as casting films and spinning… More >

Abstract Microencapsulation of neroline inside microcapsules having a polyurethane shell based on β-cyclodextrin (β-CD) and hexane diisocyanate was performed by interfacial polycondensation. The polyol nature of β-CD caused tight crosslinking of microcapsules wall. Microcapsules of neroline were characterized for their chemical composition and structure of the polyurethane shell by FTIR spectroscopy, thermogravimetric analysis, optical and electron microscopy, light scattering and electrophoresis measurements. Core content and encapsulation yield were 15% and 60%, respectively. Spherical microcapsules of mean diameter 29 μm were slightly cationic with an isoelectric point of 6.3. Neroline-loaded microcapsules were fixed on cotton fabric using an impregnation technique. The functionalized… More >

Abstract It is essential to design economic and efficient tougheners to prepare high-performance epoxy resin; however, this has remained a huge challenge. Herein, an eco-friendly, low-cost, and facile-fabricated bio-based hyperbranched toughener, carboxylic acid-functionalized tannic acid (CATA), was successfully prepared and applicated to the preparation of solvent-free epoxy resins. The mechanical performance, morphology, structural characterization, and thermal characterization of toughened epoxy resin system were studied. The toughened epoxy resin system with only 1.0wt% CATA reached the highest impact strength, 111% higher than the neat epoxy resin system. Notably, the tensile strength and elongation at break of toughened epoxy resin systems increased moderately… More >

Abstract A series of the Guiqi polysaccharides/chitosan/alginate composite hydrogel microspheres (GPcM) with different particle sizes were prepared with Guiqi polysaccharides (GP), chitosan (CS) and sodium alginate (Alg). The optimum preparation process was also determined by single factor and orthogonal experiment analysis. The GPcM were characterized by fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), drug loading efficiency test (LE), encapsulation efficiency test (EE) and in vitro release study. The results showed that the Guiqi polysaccharides chitosan hydrogel (GPCH) and sodium alginate hydrogel (SAH) formed a crossover system in GPcM. The GPcM have a uniform particle size ranging from 395.1μm to… More >
