- Journal of Renewable Materials, Vol.10, No.6, pp. 1459-1470, 2022, DOI:10.32604/jrm.2022.018415
- Abstract Cellulose nanocrystal (CNC) is a biomaterial derived from plant lignocellulosic components, widely applied in various industrial fields. Concurrently, with the growth of awareness in developing green nanomaterial, the explored Washingtonia fibre could be alternative biomass for obtaining CNC products. In the present work, different acid concentrations of 5%, 15%, and 25% hydrochloric solutions were employed to produce CNCs from Washingtonia fibre. With the chemical treatments, the yield of the CNC product was successfully retained at 21.6%−25.1%. Individually separated and needle-shaped CNC particles could be observed under the microscopic viewing with the increased acid concentrations. From elemental analysis, a relatively pure… More

- Abstract This study evaluated the methods of grafting commercial catechin with fatty acids, namely capric acid (C10), lauric acid (C12), and myristic acid (C14) through esterification. Specimens of beech wood (Fagus sylvatica L.) were impregnated with catechin and modified catechin-fatty acids, separately, at a 5% concentration diluted in ethanol using vacuum pressure treatment and subjected to leaching. The weight percentage gain before leaching (WPG), after leaching (WPGAL), and weight loss due to leaching (PL) were investigated. Both leached and unleached samples were tested against white-rot fungi (Trametes versicolor) in Petri-dishes for twelve weeks. Results show that samples treated with modified catechin-fatty… More

- Abstract Creep test results of glulam members under compression and bending were studied in this paper. The creep tests were conducted to investigate the influence of the stress level and relative eccentricity on the creep deformation of glulam members. The test results showed that the creep deformation trends of glulam members under long-term compression and bending loading were similar; the creep deformation increased with increases in both the stress level and relative eccentricity. However, the relative creep deformation decreased with the increase in both the stress level and relative eccentricity under long-term loading, and a five-parameter creep model was proposed to… More

- Abstract Biomass is a carbon-neutral renewable energy resource. Biochar produced from biomass pyrolysis exhibits preferable characteristics and potential for fossil fuel substitution. For time- and cost-saving, it is vital to establish predictive models to predict biochar properties. However, limited studies focused on the accurate prediction of HHV of biochar by using proximate and ultimate analysis results of various biochar. Therefore, the multi-linear regression (MLR) and the machine learning (ML) models were developed to predict the measured HHV of biochar from the experiment data of this study. In detail, 52 types of biochars were produced by pyrolysis from rice straw, pig manure,… More

- Preparation and Characterization of Waterborne Polyurethane with Unique Nanoparticles by Controlling Water
- Journal of Renewable Materials, Vol.10, No.6, pp. 1623-1639, 2022, DOI:10.32604/jrm.2022.018935
- Abstract A facile method, focusing on emulsification, chain extension and dispersion process in preparing waterborne polyurethane, was developed to prepare emulsion with rod-like nanoparticles. The facile method involves a water addition procedure by in situ generated water to react with polyurethane prepolymer instead of the external water addition process. As a comparison, waterborne polyurethane was synthesized through the external water addition process. According to the characterization methods including FTIR, 1H-NMR, TEM and water swelling experiments, it is suggested there are two kinds of hydrogen bonds interactions in hard/soft domain of the novel polyurethane, and the phase separation of hard/soft domains increases… More

- Journal of Renewable Materials, Vol.10, No.6, pp. 1693-1710, 2022, DOI:10.32604/jrm.2022.018475
- Abstract In order to study the mechanical properties and micro-mechanism of industrial waste fly ash-reinforced cement calcareous sand (FCS), the triaxial unconsolidated undrained (UU) test and scanning electron microscope tests (SEM) were carried out on it. The results of UU test show that the peak stress and energy dissipation of the FCS sample first increase and then decrease with the increase in fly ash content. Fly ash enhances the cement calcareous sand by increasing both the cohesion and internal friction angle, and adding 10% content of fly ash gives the largest values. The SEM test results shows that the hydration products… More
