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 […]
P5.5 – 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 […]
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 […]
P5.9 – Itaconic-modified Bleached Kraft Pulp for Matierals Applications
Itaconic acid is a naturally occurring dicarboxylic acid, produced by microorganisms through the fermentation of sugars, and has been named a great candidate for a future bio-based platform chemical. As it contains two carboxylic acid groups, alongside an unsaturation, several reactions may be performed to polymerize or conjugate the acid to bio-materials. In this study, […]
P5.10 – Automated Optimization of Flow-Focusing Parameters for High Thermal Conductivity of Nanocellulose Filaments
Achieving a circular economy necessitates the transition to sustainable, green materials. Cellulose-based materials, long utilized in papermaking and textiles, hold great potential owing to their exceptional mechanical strength, lightweight nature, and biocompatibility. Cellulose’s properties can be finely tuned by controlling its structure at the micro- and nanoscale, thereby enabling superior performance across diverse applications.Cellulose filaments […]
P5.12 – Techno-economic analysis of solvent treated nanocellulose based membranes for ultrafiltration
Over the past years, nanocellulose has attracted notice as a renewable and biodegradable alternative to synthetic materials [1]. Nanocellulose structures offer highly hydrophilic anti-biofouling surfaces and improve the membrane’s size-selective separation ability [2]. Despite these advantages, mechanical stability and economic viability remain to be significant challenges for nanocellulose-based membranes. One of the possibilities to tackle […]
P5.11 – Additive Manufacturing of Nano Flax Fibre Reinforced PLA Bio-Composites: Fabrication, Characterization, and Performance Analysis
Additive Manufacturing (AM) enables the fabrication of complex structures through a layer-by-layer material deposition process. It offers advantages such as short design cycles, high material efficiency, and suitability for intricate geometries compared to traditional subtractive methods. Among AM techniques, Fused Filament Fabrication (FFF) is one of the most widely used technique due to its affordability, […]
P5.13 – Textile waste recycle via a high value approach: a continuously spinning method of regenerated fibers
The textile industry is currently facing immense pressure to transition towards sustainable development. However, waste textiles and fibers are still mainly disposed of in landfills or by incineration after their service life and thereby pollute the natural environment. In the study, we extracted keratin from various waste textiles and used it as a raw material […]
