Abstract Power cables are important pieces of equipment for energy transmission, but achieving a good balance between flame retardancy and mechanical properties of cable sheaths remains a challenge. In this work, a novel intumescent flame retardant (IFR) system containing silicone-containing macromolecular charring agent (Si-MCA) and ammonium polyphosphate (APP) was designed to synergistically improve the flame retardancy and mechanical properties of ethylene-butyl acrylate copolymer (EBA) composites. The optimal mass ratio of APP/Si-MCA was 3/1 in EBA composites (EBA/APP-Si-31), corresponding to the best flame retardancy with 31.2% of limited oxygen index (LOI), V-0 rating in UL-94 vertical burning More > Graphic Abstract

Abstract This study investigates the compatibility and efficacy of combining ammonium molybdate (AM) with antagonistic bacteria Bacillus amyloliquefaciens B10W10 and Pseudomonas sp. B11W11 for brown rot control (Monilinia laxa). In vitro experiments reveal variable mycelial growth inhibition rates compared to untreated controls, with B11W11 + 0.5% AM and B10W10 + 2% AM displaying the highest inhibition rates after 5 days. After 10 days, the 2% AM + B10W10 combination exhibits the highest inhibition rate. Microscopic observations show structural alterations in mycelium within inhibition zones, marked by vacuolization. The antagonistic bacteria, alone or with different ammonium molybdate concentrations, significantly impact M. laxa… More >

Abstract Wood, recognized as a renewable and environmentally sustainable material, plays a crucial role as an alternative energy resource within the construction industry. However, it is highly susceptible to mold and decay fungi, which can lead to surface discoloration and potentially compromise the structural integrity of wood. The advancement of nanotechnology has introduced innovative strategies for wood protection, enhancing its performance while imparting additional properties. Various approaches including nanosized metals, polymer nanocomposite and coating treatments are actively being explored in this field. Furthermore, integrating bio-based materials with nanotechnology offers a green and sustainable method for wood More >

Abstract This work explores the dielectric and electrochemical properties of solid biopolymer blend electrolytes (SBEs) based on a combination of alginate and polyvinyl alcohol (PVA), doped with varying concentrations of ammonium iodide (NH₄I). The SBEs were synthesized using the solution casting method, and their ac conductivity exhibited an optimal value of 1.01 × 10⁻⁵ S · cm⁻¹ at 25 wt.% NH₄I. Detailed dielectric and modulus spectroscopy analyses revealed distinctive trends in relation to NH₄I concentration, suggesting complex dielectric relaxation behavior. The universal power law (UPL) analysis identified the Small Polaron Hopping (SPH) mechanism as the dominant conduction process in More >

Abstract Despite its considerable potential, oil palm trunk (OPT) remains underutilized, largely owing to the cyclical replanting process that occurs every 25–30 years. This study aimed to address this issue by developing an eco-friendly oriented strand board (OSB) using vascular bundles (VBs) from oil palm, both in binderless form and with the incorporation of natural adhesives made from sucrose and ammonium dihydrogen phosphate (ADP). The VB was extracted from OPT using a pressure cooker and mixed with a sucrose-ADP solution at various ratios. The mixture was then pressed at temperatures of 180°C and 200°C for 10… More > Graphic Abstract

Abstract Drought stress negatively impacts agricultural crop yields. By using mineral fertilizers and chemical regulators to encourage plant development and growth, its impact can be mitigated. The current study revealed that exogenous silicon (Si) (potassium silicate; K₂Si₂O₅ at 1000 ppm) and molybdenum (Mo) (ammonium molybdate; (NH₄)₆Mo₇O₂4•4H₂O at 100 ppm) improved drought tolerance in quinoa (Chenopodium quinoa Willd). The research was conducted in a randomized complete block design with three biological replicates. The treatments comprised T0 (control, water spray), T4 (drought stress), and T1, T2, T3, T5, T6, and T7, i.e., foliar applications of silicon and molybdenum solutions individually… More >

Abstract Furfurylated wood exhibits excellent dimensional stability and corrosion resistance, making it a promising material for constructing buildings, but it is highly flammable. Herein, flame-retardant furfurylated poplar wood was produced via a two-step process utilizing boric acid (BA) and ammonium dihydrogen phosphate (ADP) as flame-retardant components, and biomass-derived furfuryl alcohol (FA) as a modifier. The acidity of BA and ADP allowed them to catalyze the polymerization of FA, which formed a cross-linked network that immobilized BA and ADP inside the wood. The addition of BA/ADP substantially delayed the time to ignition from 10 to 385 s More > Graphic Abstract

Abstract Bio-based cyclodextrins (CDs) are a common research object in supramolecular chemistry. The special cavity structure of CDs can form supramolecular self-assemblies such as vesicles and microcrystals through weak interaction with guest molecules. The different forms of supramolecular self-assemblies can be transformed into each other under certain conditions. The regulation of supramolecular self-assembly is not only helpful to understand the self-assembly principle, but also beneficial to its application. In the present study, the self-assembly behavior of epoxy-β-cyclodextrin (EP-β-CD) and mixed anionic and cationic surfactant system (sodium dodecyl sulfate/dodecyltrimethylammonium bromide, SDS/DTAB) in aqueous solution was studied.

Abstract

Plant growth and resilience to abiotic stresses, such as soil salinity and drought, depend intricately on nitrogen metabolism. This review explores nitrogen’s regulatory role in plant responses to these challenges, unveiling a dynamic interplay between nitrogen availability and abiotic stress. In the context of soil salinity, a nuanced relationship emerges, featuring both antagonistic and synergistic interactions between salinity and nitrogen levels. Salinity-induced chlorophyll depletion in plants can be alleviated by optimal nitrogen supplementation; however, excessive nitrogen can exacerbate salinity stress. We delve into the complexities of this interaction and its agricultural implications. Nitrogen, a vital element

Abstract High purity ammonium metavanadate (NH₄VO₃) is the most vital chemical to produce V₂O₅, VO₂, VN alloy, VFe alloy and VOSO₄, which have some prospective applications for high strength steel, smart window, infrared detector and imaging, large scale energy storage system. NH₄VO₃ is usually produced by spontaneous crystallization from the aqueous solution due to its sharp dependence of solubility on the temperature. However, hazardous chemicals in industrial effluent, include phosphorate, silicate and arsenate, causing severe damage to the environment. In this work, these impurities are selectively precipitated onto inorganic flocculants, while the vanadate dissolved in an aqueous solution keeps More > Graphic Abstract
