Abstract To mitigate the environmental hazards of traditional petroleum thermosets and develop sustainable alternative materials, in this work, Dehydroabietylamine (DHAA), a renewable rosin derivative, was employed as the bio-based raw material to fabricate an environmentally benign vitrimer. Diglycidyl Dehydroabietylamine Epoxy Resin (DGDHAA) was first synthesized using DHAA and epichlorohydrin (ECH). The chemical structure of the synthesized DGDHAA was systematically characterized by FT-IR, 13C NMR, and 1H NMR techniques. Subsequently, a bio-based vitrimer (denoted as DGDHAA/ESO-MNA) was prepared through the epoxy-anhydride curing reaction, with DGDHAA as the matrix, epoxidized soybean oil (ESO) as the toughening modifier, and methyl… More >

Abstract Gray mold disease induced by Botrytis cinerea is a devastating fungal infectionthat severely impairs the production of fruits and vegetables, especially strawberries. Conventional chemical fungicides not only cause severe environmental contamination but also readily induce fungicide resistance in Botrytis cinerea. Applying plant-derived natural antimicrobial agents, such as eugenol, as alternatives to chemical fungicides is a pivotal strategy for the development of green agriculture. However, ordinary eugenol emulsion biopesticides suffer from severe drawbacks, including easy leaching, rapid volatilization, and oxidation, which severely limits their effective control against Botrytis cinerea. In this study, an anionic waterborne polyurethane (PEOC-WPU) emulsion was… More >

Abstract The viscosity of polymer solutions often decreases significantly due to shear degradation in near-wellbore zones and chemical/aging degradation during long-term transport, which seriously compromises the efficiency of polymer flooding. In this study, a hydrophobic monomer, hexadecyl dimethyl-5-enhexyl ammonium bromide (HAB), was synthesized. Subsequently, a novel viscosity stabilizer (LC12) was prepared via micellar polymerization of acrylamide and HAB using sodium dodecyl sulfate (SDS) as a solubilizer. The effect of this stabilizer on a hydrophobic associating polymer (AP-P4) was evaluated. Experimental results revealed that the addition of LC12 accelerated the dissolution rate of the polymer concentrate and More >

Abstract This study focuses on the reinforcement of thermosetting matrices with lignocellulosic fibers and the limited interfacial compatibility that remains a major obstacle to the structural use of bio-based composites. The effect of chemical surface treatment on the interfacial behavior and macroscopic performance of unsaturated polyester resin (UPR) reinforced with Luffa fibers (LF) is studied in depth. LF was treated with two different chemical treatments: (i) alkaline treatment with sodium hydroxide (NaOH) and (ii) a combined NaOH/acetic acid (CH3COOH) treatment. The structural and morphological characteristics of the LF treated were examined using Fourier Transform Infrared Spectroscopy (FTIR)… More >

Abstract Hepatitis has imposed a substantial burden on human health. Tumor necrosis factor-α (TNF-α) drives the inflammatory response by triggering downstream signaling, particularly the nuclear factor kappa B (NF-κB) pathway. Suppressing NF-κB activation represents a promising therapeutic strategy. PEGNB, a polymeric hydrogel, exhibits significant potential due to its superior cytocompatibility. We developed a controlled-delivery microgel platform by encapsulating Schisandra lignans (SLs) and mesenchymal stromal cells (MSCs) in polyethylene glycol-norbornene (PEGNB) microgels. To mimic an inflammatory hepatic microenvironment in vitro, Lipopolysaccharide (LPS)-induced HepG2 cells were encapsulated in bulk PEGNB hydrogel. The microgel–cell system enabled localized co-delivery of SLs… More >

Abstract Health remains a persistent focus of research. Currently, many commonly used synthetic dyes are toxic to some extent. Tartrazine is a common synthetic dye used in the food, pharmaceutical, printing, and dyeing industries. Long-term exposure to this substance or its ingestion may pose significant health risks. In addition, oxidizing agents used in water treatment may threaten environmental and human health if they are not properly controlled. Hydrogen peroxide (H2O2) is one of the most widely used oxidants and therefore requires effective monitoring. Against this background, this study contributes to the efficient detection of environmentally harmful substances… More >

Abstract Dental caries (or tooth decays) is a common oral disease in early childhood and adults of all ages, which is caused by long-term synergies of acid-producing bacteria and fermentable carbohydrates in the oral environment. The use of existing dental restorative materials (including silver amalgams, light-cured resins, and dental restorative composites) and dental restorative composites (including glass ionomers cement, despite being sealants, releasing fluoride and promoting remineralization) is commercially restricted due to their weak mechanical properties, poor abrasion resistance, low elastic modulus, improper shrinkage, less polishability, brittleness, poor wear resistance tensile strength, aesthetic etc. Therefore, the… More >

Abstract The increasing prevalence of plastic pollution demands strategies for sustainable biodegradable plastic production. Marine bacteria can be found on all continents able to survive in a variety of salinity levels and may be used to biosynthesis polyhydroxyalkanoates (PHAs), which can serve as a bioplastic substitute for conventional petroleum-based plastics. This paper presents a literature review and case study examining marine PHAs-producing microorganisms in the context of a circular bioeconomy and waste management. More specifically, it examines the marine PHA-producing bacteria's ability to utilise varying and renewable carbon substrates for PHA biosynthesis. From prior research studies, More >

Abstract Underwater adhesives serve as essential functional materials with extensive applications in underwater robotic operations, submarine pipeline installation and maintenance, maritime defense projects, and marine engineering infrastructure. However, the construction of robust and reliable underwater bonding interfaces is severely constrained by substrate surface hydration layers and limited interfacial interaction strength, which has become a core bottleneck restricting the development of high-performance underwater adhesives. Herein, we use in situ polymerization and particle reinforcement to enhance adhesion strength: An underwater adhesive is prepared by reacting bis(3-aminopropyl)-terminated polydimethylsiloxane with hexamethylene diisocyanate in the presence of Ca(OH)2, which acts as a precursor… More >
