The bio-delignification of OPEFB fiber was carried out using white-rot fungi (Tremetes versicolor and pre-bleaching pulp with xylanase.

The result exhibits that the cellulose content of OPEFB pulp using bio-delignification increased significantly compared to chemical treatment. Furthermore, the concentration of enzyme and hydrolysis time in the synthesis treatment affect reducing average particle size and increasing the crystallinity index while decreasing the yield of NCC produced. The synthesis process was under optimal processing conditions at 1% enzyme concentration and 3 days of hydrolysis time resulting in the NCC product with 155 nm of average particle size, 66.78% of crystallinity index, and a yield of 38.28%.

Coconut coir, as part of coconut which is considered as waste, contains useful components. It contains high cellulose which is could be used in fiber industries. Meanwhile, coconut coir also contains lignin which needs to be separated. In this study, a delignification process was used to remove the brown color on the fiber caused by the lignin content. The delignification process was a pretreatment before the cellulose extraction was carried out. It had been done in the various NaOH concentration (0.5; 1; and 1.5 M), reaction time (1; 1.5; and 2 hours) and the reaction temperature (60,70, and 80 oC). This study aims to determine the cellulose content and the factor that affected the cellulose extraction and the characteristics of the cellulose extracted from the coconut coir. The Chesson Data method and SEM analysis have been used for the characterization of the cellulose. The delignification method known has the potential as a simple and effective method for extracting cellulose from natural materials. The result shows that the optimum cellulose content obtained at 100 mesh coir particle size, 1.5 M NaOH concentration, at 80°C for 1.5 hours was 69.82 %.","PeriodicalId":153677,"journal":{"name":"Journal of Fibers and Polymer Composites","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124149205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the tensile strength of the PP MF35-CaCO3 composites decreased with increasing nano-CaCO3 content. Meanwhile, the hardness of the nanocomposites increased with increasing nano-CaCO3 content, but decreased the melting point and heat of fusions (ΔHm) of the nanocomposites. The infrared spectrum showed that the interaction between PP MF35 and nano-CaCO3 was only physical interaction and there was no chemical reaction.","PeriodicalId":153677,"journal":{"name":"Journal of Fibers and Polymer Composites","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126393846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lithium-ion batteries (LIBs) have become widely used powder sources for portable electronics and electric vehicles. The discovery of lithium nickel manganese cobalt oxide (LiNi0.5Mn0.3Co0.2O2, NMC532), tremendous efforts have been paid to the development of Ni-rich layer-structured NMC532 materials due to its high capacity when charged to potentials higher than 4.3 V vs Li+/Li. In this work we report effect of Sodidium in NMC532 layer, the characterization was done by using X-Ray Diffractometer (XRD) to investigate the crystal structure, Electrochemical impedance spectroscopy (EIS) was used to illustrate the resistance change during cycling. The particles morphology and surface chemistry characterizations of both cathode and anode electrodes were performed on Scanning Electron Microscope (SEM).

Na does not affect the NMC532 lattice parameters, which means that Na which is expected to substitute for Li does not occur. The NMC532 conductivity with the addition of Na=0.03 showed a slightly lower value than the NMC532 conductivity with the addition of Na=0.01. Meanwhile, the highest conductivity was seen at NMC532 with the addition of Na=0.05. The addition of Na to NMC532 did not increase the conductivity linearly. SEM images of NMC532 and NMC532 with the addition of Na=0.01; Na = 0.03 and Na = 0.05 can be seen that the Na flakes wrap around the NMC532 granules.

The purpose of this research is to make activated carbon from coconut shell carbon and examine its use in adsorbing metals in acid mine drainage; to study the types of activators; to determine the optimum mass for the efficiency of reducing the concentration of Cu2+ metal and Mn2+ metal (percent removal) using the activated carbon from coconut shell carbon; and to determine the adsorption of isothermal model. Based on the results of the study, it is concluded that activated carbon could be made from coconut shell carbon with 20% H3PO4 chemical activation. Before being activated, it was made by heating at a temperature of 300°C for 2 hours. The best activated carbon in terms of metals adsorption in acid mine drainage was in a mass of 4 grams with each percent removal of 57.62% for Cu metal and 91.37% for Mn metal. Data analysis of the effect of concentration on adsorption capacity used the Langmuir and Freundlich isotherm equations. The Langmuir equation for the adsorption of Mn metal obtained the maximum adsorption capacity (qmax) of 15.16 mg/g; KL=73.09 mol/L and R2=0.9568. Meanwhile, the adsorption of Cu metal obtained the maximum adsorption capacity (qmax)=4.73 mg/g; KL=73.14 mol/L and R2= 0.9304. In Freundlich's equation, on the adsorption of Mn metal, the resulting KF=15.14 mol/L; R2=0.9129, while on the adsorption of Cu metal, the resulting KF=.72 mol/L; R2= 0.9092. Based on the data, the adsorption isotherm curve more closely follows the Langmuir isotherm model (adsorption takes place in one layer (monolayer).","PeriodicalId":153677,"journal":{"name":"Journal of Fibers and Polymer Composites","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114836040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
