P2.28 – Lignin-based organogels: a tough and flexible renewable solution
Organogels are soft materials fused with an organic liquid phase. Developing organogel with good mechanical durability, non-toxicity, and environmental stability offers potential for diverse applications. However, conventional organogels often rely on synthetic materials and toxic solvents, exhibit insufficient mechanical strength, and involve energy-intensive fabrication methods. Biobased organogels offer certain advantages. In this regard, lignin, a […]
P1.24 – Towards more sustainable tissue products
Fully bleached fibers are typically preferred in hygiene and tissue products due to their high brightness, water absorption capacity, and softness. However, environmental challenges require sustainable alternatives and leading to an increased use of unbleached fibers. Unbleached virgin fibers that undergo extensive oxygen delignification exhibit significantly higher wet tensile strength while maintaining a good absorption […]
P13.10 – Sustainable Technology for Fabrication of Hydrophobic Cellulose Foam
Bio-based lightweight materials have attracted significant attention from both academia and industry as sustainable alternatives to fossil-based materials.1,2 Although some bio-based lightweight materials have been successfully studied so far, most of them are often not fully bio-based and their fabrication involve the use of organic solvent and sometimes complicated process. Here in we report the […]
P4.8 – Activated carbon aerogel of high specific surface area and strength based on nitro-oxidized banana rachis aerogel for methylene blue dye removal
Activated carbon aerogel derived from banana rachis, an easily accessible agricultural waste, features a unique interconnected network structure that is ideal for water purification. This study investigated the preparation of activated carbon aerogel from banana rachis through four distinct processes: nitro-oxidation, lignin impregnation, carbonization, and CO 2 activation. The goal is to have a lightweight […]
P5.2 – Nanocellulose-based Fabry–Pérot Optical Cavity
Reflective structural colour is an hot-topic in research nowadays as a substitute for dyes and pigments. The ideal system should provide high reflectance efficiency and chromaticity, along with good tunability to obtain the required colour. In this study, we demonstrate the production of high reflectance efficiency and good chromaticity structural colours based on the Fabry–Pérot […]
P11.16 – Achieving High Dissymmetry Circular Emission in Silica–CNC Composites
Crystalline nanocellulose (CNC), one of the abundant materials in nature, exhibits a left-handed chiral nematic organization that gives rise to pronounced circular dichroism. This intrinsic chiroptical property enables CNC-based structures to generate circularly polarized photoluminescence, making them promising candidates for diverse photonic and optoelectronic applications. In this study, we present a facile and scalable vacuum […]
P5.8 – Solutions for Cellulose Nanofibers
Cellulose nanofibers (CNF) are plant-derived carbon-neutral materials which are light-weight and strong, yet they also exhibit high elasticity and resistance to heat. Furthermore, the main component of CNF, cellulose, can be biosynthesized in large quantities through photosynthesis and it is abundantly available in nature. Shimadzu provides solutions for detailed analysis of CNF properties such as […]
P3.16 – Chemically Recyclable and Enzymatically Degradable α-Pinene-derived Polyesters for Adhesive Applications
The production of bio-based polymers is crucial for addressing the environmental and socio-economic challenges posed by fossil-based plastics. It is increasingly important to design degradable bio-based polymers, as not all bio-based polymers are biodegradable. Moreover, the exploration of biomass-based diols for creating materials with tunable properties has been limited. α-Pinene, a significant forestry-derived material, has […]
P5.4 – Molecular Engineering of Lignocellulose Bio(nano)composites Interphase
The development of biodegradable and recyclable bio(nano)composites based on renewable resources can contribute to mitigating the effects of plastic pollution and the depletion of fossil fuels. In this frame, thermoplastic biodegradable polyesters blended with lignocellulosic derivatives are of interest. Reactive melt processing is a sustainable and scalable strategy to tackle the drawbacks of poor lignocellulose […]
P2.26 – Lignin-Silica Sorbent: An Environmentally Friendly Approach to Water Purification
The growing demand for clean water, driven by population growth, urbanization, and industrialization, has intensified the need for effective water purification methods. Contamination by heavy metals, chemical compounds, microplastics, and pharmaceutical waste poses significant risks to ecosystems and human health.Lignin, a natural biopolymer with a high density of functional groups, can effectively bind cations. However, […]
