| 1 | Development and Characterization of Eco-Friendly Non-Isocyanate Urethane Monomer from Jatropha curcas Oil for Wood Composite Applications显示文摘The aim of this research work was to evaluate the potential of using renewable natural feedstock,i.e.,Jatropha curcas oil(JCO)for the synthesis of non-isocyanate polyurethane(NIPU)resin for wood composite applications.Commercial polyurethane(PU)is synthesized through a polycondensation reaction between isocyanate and poly-ol.However,utilizing toxic and unsustainable isocyanates for obtaining PU could contribute to negative impacts on the environment and human health.Therefore,the development of PU from eco-friendly and sustainable resources without the isocyanate route is required.In this work,tetra-n-butyl ammonium bromide was used as the activator to open the epoxy ring with 3-Aminopropyltriethoxisylane as a catalyst to yield urethane of JCO(UJCO).The UJCO were characterized by Fourier Transform Infra-Red spectroscopy(FTIR)and their oxirane,and hydroxyl values were measured.The result showed that a decrease in oxirane value was found while the hydroxyl value was increased during the time,confirming that the urethane group was formed.The presence of functional groups in FTIR spectra at wave numbers 1732.08,1562.34,and 3348.42 cm^(−1) indicates the functional groups of C=O(urethane carbonyl),–NH,and–OH,respectively confirmed this finding.The potential applications of NIPU in the wood composite were also outlined. | Samsul Bhakri Muhammad Ghozali Edy Cahyono Evi Triwulandari Witta Kartika Restu Nissa Nurfajrin Solihat Apri Heri Iswanto Petar Antov Viktor Savov Lee Seng Hua ErikaAyu Agustiany Lubos Kristak Widya Fatriasari | 2023 | Journal of Renewable Materials2023,11,1: | 2 |

| 7 | Characterization of Formacell Lignin Derived from Black Liquor as a Potential Green Additive for Advanced Biocomposites显示文摘Black liquor is obtained as a by-product of the pulping process,which is used to convert biomass into pulp by removing lignin,hemicelluloses and other extractives from wood to free cellulose fibers.Lignin represents a major constituent in black liquor,with quantities varying from 20%to 30%,of which a very low share is used for manufacturing value-added products,while the rest is mainly burned for energy purposes,thus underestimating its great potential as a raw material.Therefore,it is essential to establish new isolation and extraction methods to increase lignin valorization in the development of bio-based chemicals.The aim of this research work was to determine the effect of KOH or ethanol concentration as an isolation agent on lignin yields and the chemical characteristics of lignin isolated from formacell black liquor of oil palm empty fruit bunch(OPEFB).Isolation of lignin was carried out using KOH with various concentrations ranging from 5%to 15%(w/v).Ethanol was also used to precipitate lignin from black liquor at concentrations varying from 5%to 30%(v/v).The results obtained showed that the addition of KOH solution at 12.5%and 15%concentrations resulted in better lignin yield and chemical properties of lignin,i.e.,pH values of 3.86 and 4.27,lignin yield of 12.78%and 14.95%,methoxyl content of 11.33%and 10.13%,and lignin equivalent weights of 476.25 and 427.03,respectively.Due to its phenolic structure and rich functional groups that are favorable for modifications,lignin has the potential to be used as a green additive in the development of advanced biocomposite products in various applications to replace current fossil fuel-based material,ranging from fillers,fire retardants,formaldehyde scavengers,carbon fibers,aerogels,and wood adhesives. | Sri Hidayati Eugenia Fonny Budiyanto Hadi Saputra Sutopo Hadi Apri Heri Iswanto Nissa Nurfajrin Solihat Petar Antov Lee Seng Hua Widya Fatriasari MohdSapuan Salit | 2023 | Journal of Renewable Materials2023,11,6: | 0 |
| 8 | 空间调味品显示文摘如果食物缺少了佐料的辅助,耶将很难成为美食,而这对于"美食控"的人来说是一件痛苦的事儿,诸如陈醋、方糖、料酒、辣椒酱这样家庭必备的调味品丰富了食物的味道,给我们带来多种多样的美食休验。而我们居住的空间,它就像一份未加工过的食物原料,给它添加什么佐料,做成什么样的味道,我们可以根据自己的喜好来设定。灯与墙面的设计在居住空间中可以起到很重要的装饰与调味作用。一盏与众不同的灯具可以让居住空间看起来更有亮点;一个出其不意的墙面设计也可以在美化空间的同时又巧妙地利用空间,成为摆放书籍和小物品的地方。 | Pavel Vetro Dmitry Kozinenko Nissa Kinialina Matteo Agati Valenca Castells Legchatov Ilya 李薇 范嘉苑 | 2015 | 现代装饰(家居)2015,0,6: | 0 |
