The imperative challenge of repurposing recycled carbon fiber (rCF) in composite structures, due to its cost-effectiveness and eco-friendly attributes, has spurred innovative research. This study introduces a scalable processing technique, integrating nanotube (CNT)-bonded microfibrillated cellulose (MFC) onto randomly oriented rCF mats, focusing on enhancing mechanical properties. Employing electrophoretic deposition (EPD), surfaces are effectively functionalized with CNT/MFC, probed...

Cellulose-based fiber-reinforced composites are gaining attention for their eco-friendly attributes and cost-effectiveness.

A new regioselective route is introduced for surface modification of biological colloids in the presence water. Taking case cellulose nanofibers (CNFs), we demonstrate a site-specific (93% selective) reaction between primary hydroxyl groups (C6-OH) and acyl imidazoles. CNFs bearing C6-acetyl C6-isobutyryl groups, with degree substitution up to 1 mmol g-1 are obtained upon esterification, affording adjustable energy. The morphological structural features remain largely unaffected, but...

Owing to its purity and exceptional mechanical performance, bacterial nanocellulose (BNC) is well suited for tissue engineering applications. BNC assembles as a network that features similarities with the extracellular matrix (ECM) while exhibiting excellent integrity in wet state, suitable suturing sterilization. The development of complex 3D forms shown by taking advantage aerobic process involved biogenesis at air/culture medium interphase. Hence, solid supports are used guide formation...

This study investigates the effect of fibers from cotton and polyester textiles on properties fiber-reinforced polypropylene (PP) composites aimed at durable load-bearing materials. Herein we developed a process-centered strategy to introduce 52 wt% within thermoplastic matrix, while ensuring proper interfacial coupling. We examined mechanical, thermal, rheological composite materials that integrated waste into PP matrices with different coupling agents. Our findings highlight balance...

Colloids are suitable options to replace surfactants in the formation of multiphase systems while simultaneously achieving performance benefits. We introduce synergetic combination colloids for interfacial stabilization complex fluids that can be converted into lightweight materials. The strong interactions between high aspect ratio and hydrophilic fibrillated cellulose (CNF) with low hydrophobic particles afford superstable Pickering foams. foams were used as a scaffolding precursor porous,...

Compared to oil-based counterparts, they provide several advantages low carbon footprints, ease reusability recyclability abundancy, comparable price ranges. consideration increasing usage, present study focused on development analysis material blends by merging state-of-the-art...

Soil quality is one of the main limiting factor in development food sector arid areas, mainly due to its poor mechanics and lack water retention. Soil's organic carbon nearly absent soils, though it important for nutrient transport, soil mechanics, prevent erosion, as a long-term sink. In this study, we evaluate potential benefits that are brought inert sand by incorporation range of, mainly, cellulosic networks their polymeric or structured (fiber) forms, analogously those found healthy...

Lightweight, energy-efficient materials in building construction typically include polymeric and composite foams. However, these pose significant fire hazards due to their high combustibility toxic gas emissions, including carbon monoxide hydrogen cyanide. This study delves into the latter aspects by comparing hybrid systems based on nanofiber-reinforced silica-based Pickering foams with a synthetic reference (polyurethane foams). The extent dynamics of retardancy evolution were assessed,...

The predominant technique for producing 3D-printed structures of nanocellulose involves freeze-drying despite its drawbacks in terms energy consumption and carbon footprint. This study explores the less-energy-intensive drying approach by leveraging valorization forest residual streams. We utilized wood flour Kraft lignin as fillers to facilitate room-temperature nanocellulose-based 3D printed structures. Various ink formulations, integrating cellulose nanofibers, flour, lignin, were tested...
