Wood is a natural composite material mainly consisting of three components, i.e., cellulose, hemicellulose, and lignin. It exhibits complex hierarchical structure characterized by open channels, aligned in the growth direction, having specific porosity at micro-, meso-, macro-scale, an extended opacity, due to adsorption phenomena because presence lignin scattering, as different refractive indexes characterize its components. Even if during historical ages some applications have been replaced other materials, wood still covers large part common uses, which range from biomass for energy recovery building sector, or artifacts household/furniture manufacturing. Despite real invention dating 1992, only about ten years ago two independent research groups, one University Maryland (USA) Royal Institute Technology (Sweden) rediscovered started thoroughly investigate so-called transparent (TW). TW can be derived almost any through chemical treatments focused on These aim completely remove this component eliminate chromophore groups present pristine material, hence obtaining, after direct densification infiltration with suitable polymer resin, new very high transparency, toughness, lightness. characteristics further combined features (such environmental protection, flame retardancy, photoluminescence, storage ability, among others), way toward development new, up-to-date, advanced, sustainable materials both structural functional purposes, fulfilling current concepts circular economy sustainability. The review aimed providing reader overview wood, describing latest and, finally, discussing challenging issues perspectives possible developments forthcoming years.

To address shale wellbore instability and promote sustainable development in the oil gas drilling industry, chitin nanofibers (ChNFs) were extracted from shrimp shells employed as environmentally friendly inhibitors for first time. Two types of ChNFs, namely, 2,2,6,6-tetramethylpiperidinooxy (TEMPO)-mediated oxidized ChNFs (T-ChNFs) deacetylated T-ChNFs (DT-ChNFs), prepared through TEMPO-mediated oxidation shell-derived partial deacetylation obtained T-ChNFs, respectively. Due to abundance hydroxyl, carboxyl, amide groups, both DT-ChNFs formed hydrogen bonds with clay particles, adsorbed on surface, thereby demonstrated superior inhibition capacity than conventional inhibitor potassium chloride (KCl). Moreover, capable replacing interlayer water intercalation, effectively inhibiting invasion into interlayer. positive charges surface exhibited enhanced properties due more effective adsorption electrostatic interactions. Additionally, showed favorable compatibility bentonite water-based fluids (BT-WDFs). The addition significantly improved rheological BT-WDFs without compromising their filtration properties. In contrast, inclusion KCl resulted a substantial decline performance.

Abstract Increasingly serious environmental problems, including air pollution and water contamination, have led to an increasing demand for filter materials (FMs). Biopolymer nanofibrils assembled by natural macromolecules such as polysaccharides or proteins exist widely nanobuilding blocks in materials. Owing the advantages of abundant source, biodegradability, biocompatibility, high specific surface area excellent mechanical properties, biopolymer show bright prospects sustainable functional filters. This review summarizes structure preparation methods representative (cellulose nanofibrils, chitin silk nanofibrils), then outlines their emerging applications field FMs. Finally, existing challenges future opportunities this are summarized.

Abstract In recent years, natural fibers have begun to replace synthetic in automotive, building, and marine applications because of their sustainability, renewability, low cost, availability raw materials. However, strength, biocomposites are strengthened by hybridization with stronger or adding fillers. This study reinforced high‐cellulose jute fiber composites cellulose‐based almond ( Prunus amygdalus ) shell filler (ASF). Natural waste shells were ground microparticle size. Hybrid prepared microparticulate ASF the at 0%, 1.5%, 3%, 4.5%, 6% weight. A comprehensive experimental included tensile, flexural, Charpy impact (flat edgewise), shear tests. The addition significantly improved mechanical properties composites, best values obtained 3 wt.% addition. Tensile, impact, increased 48.2%, 63.5%, 24.4%, 52.2%, respectively. Scanning Electron microscopy (SEM) micrographs used morphological structural analysis prove that high achieved strengthening interlaminar adhesion. contributed developing a hybrid composite material fillers is stronger, environmentally friendly, sustainable. Highlights organic structure Almond Shell Filler (ASF) ensured sustainability composites. Cellulosic stiffness strength reduced voids, fiber‐matrix bonding, prevented debonding delamination. optimized performance 3%.
