Abstract This paper describes the development of a novel thermoset based on epoxidized hemp seed oil. The optimization of the hardener (anhydride) and crosslinking accelerator (2‐ethylimidazol) concentration as well as the curing parameters are discussed in detail. The optimized material exhibits a bio‐based carbon portion of 57.5 wt% and represents an innovative and sustainable substitute for fully petrochemical‐based resins in terms of thermal and mechanical performance characteristics.

The world’s energy demand is steadily increasing where it has now become difficult for conventional hydrocarbon reservoir to meet levels of demand. Therefore, oil and gas companies are seeking novel ways to exploit and unlock the potential of unconventional resources. These resources include tight gas reservoirs, tight sandstone oil, oil and gas shales reservoirs, and high pressure high temperature (HPHT) wells. Drilling of HPHT wells and shale reservoirs has become more widespread in the global
Beyond the need to find a non-toxic alternative to DiGlycidyl Ether of Bisphenol-A (DGEBA), the serious subject of non-epichlorohydrin epoxy resins production remains a crucial challenge that must be solved for the next epoxy resin generations. In this context, this study focuses on the valorization of vegetable oils (VOs) into thermoset materials by using (i) epoxidation of the VOs through the "double bonds to epoxy" synthetic route and (ii) synthesis of crosslinked homopolymers by UV or harden
The study examines carbon and energy footprints of jute, kenaf, sunnhemp and flax fibre production systems. Energy productivity was lowest in flax fibre production as compared to other fibre crops. Flax fibre production consumed more chemical fertilizer, diesels, pesticides and seed energy in comparison to other fibre crops. The carbon footprints of the all fibres crops did not differ significantly and were in the order of 566, 520, 445 and 423 kg CO2-eq/tonne of fibre for jute, flax, kenaf and
Lignocellulosic biomass is widely grown in many agricultural-based countries. These are typically incinerated or discarded in open spaces, which further may cause severe health and environmental problems. Hence, the proper utilization and conversion of different parts of lignocellulosic biomasses (e.g., corn wastes derived leave, cob, stalk, and husk) into value-added materials could be a promising way of protecting both health and environments. In addition, they have high-potential for myriads
High flux, monolithic water purification filters based on polylactic acid (PLA) functionalised with fish scale extracted hydroxyapatite (HAp) were prepared by solvent-assisted blending and thermally induced phase separation (TIPS), followed by twin-screw extrusion into filaments and processed <i>via</i> three-dimensional (3D) printing. The printed filters with consistent pore geometry and channel interconnectivity as well as homogenous distribution of HAp in the PLA matrix showed adsorption capa

Society still overuses polymers without fully considering their environmental impact. However, attention is increasingly shifting towards biocomposites, which already have practical applications in various fields. Despite progress, finding alternatives for complex, precise parts remain challenging. This is why we are focusing on hybrid manufacturing, which combines the benefits of 3D printing and machining. 3D printing allows us to produce parts with complex geometries, while machining ensures t
Lignocellulosic fibres have attracted growing interest as reinforcement of polymeric composite materials as a replacement of synthetic ones (mainly glass). In addition to traditional natural fibres (kenaf, hemp, sisal, flax and jute), in the last years several researchers advanced the feasibility to use also less common natural fibres, due to their low cost and availability. This work investigates the morphology and mechanical properties of fibres extracted from the leaves of the Ampelodesmos ma
Interest in biocomposites is growing worldwide as companies that manufacture high-performance products seek out more sustainable material options. Although there is significant research on biocomposite material options and processing found in the literature from at least the last two decades, there are few experimentally based case studies published to help guide product designers and engineers when considering these materials. This paper discusses the use of biocomposites in the seat of an elec
The use of biocomposites and 3D/4D printing in relation to manufacturing processes is addressed in the current book chapter. A biodegradable polymer matrix and one or more fillers are the main components of the material class known as biocomposites. Improved mechanical qualities are the result of the combination of these elements. The utilization of natural fibers, such as flax, hemp, sisal, and others, is on the rise as a viable and environmentally conscious substitute for synthetic fibers in t
Les réelles opportunités de croissance dont bénéficient les marchés liés à l'utilisation de fibres végétales en tant que renfort dans les matériaux composites sont intimement liées aux performances concurrentielles de ces fibres par rapport à celles de fibres de verre en particulier l’allégement, l’amortissement et l’isolation thermique. Dans l'industrie de la fibre de chanvre, le rouissage est le premier traitement appliqué aux plantes afin de faciliter la séparation des fibres de la partie lig

There is growing industrial and academic interest in manufacturing of biocomposite parts comprised of natural fibers in a thermoplastic matrix that begin as a commingled, unconsolidated preform. Unfortunately, little thermal property data exists in the literature for simulation/analysis of processes used to make parts (e.g., pultrusion, Automated Fiber Placement (AFP), and compression molding). In this paper, the authors explain how specific heat capacity and thermal conductivity values of both
With the rapid advances in next-generation sequencing technology, numerous non-protein-coding transcripts have been identified, including long noncoding RNAs (lncRNAs), which are functional RNAs comprising more than 200 nucleotides. Although lncRNA-mediated regulatory processes have been extensively investigated in animals, there has been considerably less research on plant lncRNAs. Nevertheless, multiple studies on major crops showed lncRNAs are involved in crucial processes, including growth a
The increasing demand and rising price of wood-based materials have led to a need for alternative raw materials in particleboard production. Agricultural waste, such as waste wood and recycled wood waste, as well as food waste, can serve as ideal alternatives to traditional wood chips, which account for more than half of the production cost. Utilizing agricultural waste, food waste, and industry materials is not only cost-effective but also a key principle of the circular economy, leading to red
Cashew (<i>Anacardium occidentale</i>) processing generates a by-product (CB) with potential for health benefits and that could be a favorable ingredient to be added to a probiotic food matrix. This study aimed to assess the functional attributes of CB in fermented milk with a probiotic and a starter culture using in vitro gastrointestinal conditions. Two formulations were tested, without CB (Control Formulation-CF) and with CB (Test Formulation-TF), and the two strains most adapted to CB, the p
As consumers' interest in nature-sourced additives has increased, zein has been treated hydrothermally under alkaline conditions to prepare a nature-sourced emulsifier. The effects of mild hydrothermal-alkaline treatment with different temperatures or alkaline concentrations on the emulsifying properties of zein were investigated. The emulsification activity and stability index of zein hydrolysates increased by 39% and 164%, respectively. The optimal simple stabilized emulsion was uniform and st
Pickering emulsions (PEs) of natural plant proteins enriched in fat-soluble components are gaining consumer interest for healthier and sustainable products. The aim of this study is to prepare PEs for stabilizing almond protein isolated (API) particles loaded with astaxanthin using ultrasound technology. The loose structure of the API at pH levels of 3 and 12, with contact angles of 68.92° and 72.56°, respectively, facilitated its transfer from the aqueous to the oil phase. The adsorption of the
The AMY1, BMY1, CTR1, and NPR1 genes play a pivotal role in onion seed germination, and their downregulation under stressful conditions has been shown to decrease germination rates. In addition, the activity of CAT, SOD, and GPx enzymes decreased by seed aging, and the amount of glucose, fructose, total sugar and electrolyte leakage increased, which ultimately led to seed deterioration. Based on the results of this experiment, it is recommended to conduct further studies into the molecular aspec
