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 […]
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 […]
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 […]
P5.21 – Scalable fabrication of customizable cellulose-based foam with pH-responsive antimicrobial functionality
In an era of growing environmental awareness, advanced cellulose-based foams are urgently needed as sustainable alternatives to petroleum-based foams. Currently, the gel process involving dynamic covalent bonds, formed by borate (B) and tannin (T), has gained significant attention in polymer network design and engineering. These bonds can reversibly break and reorganize in response to external […]
P5.1 – Enzymes-assisted synthesis and degradation of poly(ethylene brassylate) and its cellulose composites
Ethylene brassylate, a macrolactone derived from castor oil, can undergo ring-opening polymerization (ROP) to yield poly(ethylene brassylate) (PEB), a fully bio-based polyester. In this study, PEB was synthesized using reactive extrusion (REx), a technique that employs conventional melt processing equipment to facilitate chemical reactions, eliminating the requirement for organic solvents. Lipase B from Candida antarctica […]
P5.22 – Enhancing Cellulose Nanofibril Assemblies: The Role of Polymeric Nanoparticle Additives
Cellulose nanofibrils (CNFs) serve as one of the most promising biobased building blocks for the production of advanced sustainable materials. Extracted from lignocellulosic biomass, CNFs are highly crystalline fibrils with high aspect ratio, strength and stiffness. They can be assembled into foams, transparent films or fibrous reinforcements. [1] However, understanding and controlling these assemblies remain […]
P5.3 – Lightweight and strong aligned cellulose-reinforced bio-composites as sustainable functional materials
Spun cellulose filaments and biobased resins show strong potential as future sustainable materials in structural engineering, automobile manufacturing and aerospace technology. These materials display complementary properties appropriate for combination in bio-composite materials where cellulose forms the reinforcing component and the resin acts as a tough matrix. A major challenge concerns balancing structure and functional properties […]
P5.5 – Utilizing wheat straw as a lignocellulosic feedstock for thermoplastic materials: pulping, upscaling and modifications
Wheat (Triticum) is an annual cereal grain plant in the grassy family, constituting almost 50% of the total grain harvest in Sweden. Within the Vinnova Competence Centre: FibRe, we are devoted to turning wheat straw biomass into thermoformable materials with as little modification as possible. The aim is to gain in-depth understanding of how to […]
P5.6 – Probing Crystallite Alignment in Nanocrystalline Cellulose Films Using Linear and Circular Dichroism
Nanocrystalline cellulose (CNC) consists of cellulose polymers arranged in a highly ordered and uniform structure, resulting in coherent interactions with electromagnetic waves, offering significant potential in advanced optical applications due to its intrinsic anisotropy and unique chiral properties. Sulfated CNC (CNC-SO3H) stands out for its surface charge, colloidal stability, and ability to self-assemble into films […]
P5.7 – Fabrication of cellulose-based hydrogel-coated micrometer-scale neural electrodes for noninvasive peripheral nerve stimulation
Over the past decades, neural electrodes have been widely used in research and therapeutic applications for neuropsychiatric disorders such as Alzheimer’s disease, Parkinson’s disease, and epilepsy. Current clinical devices typically rely on millimeter-scale metallic electrodes, but their bulky design limits integration with fine neural structures, compromising high-resolution recordings and precise stimulation. Miniaturization of electrodes offers […]
