PACKAGING TECHNOLOGY “Advancements in Superhydrophobic Paper-Based Materials: A Comprehensive Review of Modification Methods and Applications”, Yin Tang, Shouwei Ban, Zhihan Xu, Jing Sun & Zhenxin Ning, Nanomaterials 2025, 15(2), 107. Superhydrophobic paper- based functional materials have emerged as a sustainable solution with a wide range of applications due to their unique water-repelling properties. Inspired by natural examples like the lotus leaf, these materials combine low surface energy with micro/nanostructures to create air pockets that maintain a high contact angle. This review provides an in-depth analysis of recent advancements in the development of superhydrophobic paper-based materials, focusing on methodologies for modification, underlying mechanisms, and performance in various applications. The paper-based materials, leveraging their porous structure and flexibility, are modified to achieve superhydrophobicity, which broadens their application in oil–water separation, anti-corrosion, and self-cleaning. The review describes the use of these superhydrophobic paper-based materials in diagnostics, environmental management, energy generation, food testing, and smart packaging. It also discusses various superhydrophobic modification techniques, including surface chemical modification, coating technology, physical composite technology, laser etching, and other innovative methods. The applications and development prospects of these materials are explored, emphasizing their potential in self-cleaning materials, oil–water separation, droplet manipulation, and paper-based sensors for wearable electronics and environmental monitoring. PAPER CHEMICALS “Chimeric enzymes in the pulp and paper making industry: Current developments”, Abdullah Arsalan, Yuvaraj Ravikumar, Xinrui Tang, Zijing Cao, Mei Zhao, Wenjing Sun & Xianghui Qi, Biotechnology Advances , Vol.79, March–April 2025, 108530. The pulp and paper (P&P) industry plays a vital role in supporting the social and economic progress of a country by supplying essential commodities. Conventional P&P processing often consumes significant energy and use chemical agents to produce hazardous intermediates. The use of enzymes in the P&P industry has significantly reduced both the chemical and energy demands during processing. A variety of enzyme combination cocktails are used to perform multiple functions in a single step, but often fail to operate synergistically because of significant differences in operational conditions. This lack of synergy under various operating conditions highlights the need for engineered chimeric enzymes. Moreover, enzyme engineering approaches enable enzymes to perform catalysis in sub-optimal environment. Enzymes have been engineered to improve their catalytic properties and enhance operational stability. Designing multifunctional or chimeric enzymes can function simultaneously across diverse operational conditions. Chimeric enzymes enable effective synergistic action of multiple enzymes in the P&P industry. This review aims to provide clear insights into the selective development of chimeric enzymes using enzyme engineering approaches for their effective use in the P&P industry.

Hawanis, H.A.A. Azriena, Rohah Abdul Majid, N.H.M. Hassan, M.S.N. Atikah & Abu Hassan Nordin, Sustainable Materials and Technologies , Vol.43, April 2025, e01252. The expanding demand for paper production has significantly contributed to the global economy, but it also presents substantial environmental challenges due to the diverse waste streams generated by the industry. To address these issues, eco-friendly biomaterials or also known as biopolymers are increasingly advocated in the papermaking process. The
