pilot experimental equipment and data, as well as modeling simulation, to enable a more comprehensive examination of the creping process and its mechanism. This review offers a practical overview and comprehensive understanding of the creping technology and its underlying factors for tissue production. for adsorption/separation applications in complex wastewater”, Shan Jiang, Jianfeng Xi, Hongpi Dai, Huining Xiao & Weibing Wu, Frontiers of Chemical Science and Engineering , 2023, online. A multi-functional porous paper-based material was prepared from grass pulp by simple pore-forming and green cross-linking method. As a pore-forming agent, calcium citrate increased the porosity of the paper-based material from 30% to 69% while retaining the mechanical strength. The covalent cross-linking of citric acid between cellulose fibers improved both the wet strength and adsorption capacity. In addition, owing to the introduction of high-content carboxyl groups as well as the construction of hierarchical micro-nano structure, the underwater oil contact angle was up to 165°. The separation efficiency of the emulsified oil was 99.3%, and the water flux was up to 2020 L·m−2·h−1. The theoretical maximum adsorption capacities of cadmium ion, lead ion and methyl ene blue reached 136, 229 and 128.9 mg·g−1, respectively. The continuous purification of complex wastewater can be achieved by using paper-based materials combined with filtration technology. This work provides a simple, low cost and environmental approach for the treatment of complex wastewater containing insoluble oil, organic dyes, and heavy metal ions. WOOD PANEL WASTE TREATMENT “Easily -manufactured paper-based materials with high porosity “A hybrid mathematical model for international target market decision: the case of fibreboard industry”, Murat Yeşilkaya & Yıldız Çabuk, Wood Material Science & Engineering , 2023, online. Determining the target market constitutes one of the most important strategic decisions. During the target market selection, many factors need to be considered and evaluated systematically and the most accurate choice is required to be made. In this study, the target country market selection is made for the fibreboard industry, which is one of the main sectors of the forest products industry in Turkey. For this purpose, multi-criteria decision-making (MCDM) methods, which are considered the most appropriate decision-making techniques among alternatives with many criteria, are utilised. AHP, VIKOR and TOPSIS methods are used to identify the most appropriate target market. Furthermore, a hybrid mathematical model including goal programming is proposed. And to handle ambiguity and fuzziness in international market decisions, a fuzzy goal programming model is developed. Economic, risk, supply chain and sectoral strategies are determined as the main criteria. 29 target countries are identified by including the countries ranking first in the exports of Turkey in the sector and the target countries determined by Ministry of Development. Target countries are ranked with MCDM. The rankings of the solution are compared via correlation tests. The first 10 countries are selected for the target market by employing the proposed models. “Increasing fire retardancy of natural wood fibre board with colloidal silica -based geopolymer”, Jingson Luo, Nanyang Technological University, Singapore, 2023, https://hdl.handle.net/10356/166806. Natural fibre contains cellulose, lignin, and hemicellulose, which makes it a highly flammable material. It is easily burned to decomposition and transformed into black charcoal with an average ignition temperature of around 300 Ԩ [1]. However, natural fibre is widely used in architecture by adding it into brittle concrete or polymer matrix due to the durability, sustainability, and increasing
