Natural ester dielectric fluids are eco-friendly alternatives to petroleum-based dielectrics, but oxidative instability from unsaturated bonds limits operational lifespan in transformers. While carnosic acid (CA) enhances soybean oil (SO) oxidation resistance, it introduces unacceptable dielectric loss and acidity. This challenge was addressed through the development of methyl carnosate (MC), a CA derivative that reduces acidity and dielectric loss while retaining the antioxidant catechol moiety. Thermal analysis and electron paramagnetic resonance (EPR) spectroscopy show MC significantly improves SO oxidation stability without compromising dielectric properties. MC-doped SO exhibits > 10 °C higher oxidation onset temperature and delayed thermo-oxidative decomposition due to potent radical scavenging. Conformational analysis and bond dissociation enthalpy calculations reveal that MC’s dominant conformation, stabilized by intramolecular hydrogen bonding, facilitates preferential H-donation from the hydroxyl group ortho to the aliphatic ring, confirming sacrificial antioxidant behavior. MC is a promising eco-friendly antioxidant for natural ester dielectrics, enhancing longevity and performance.

Converting biomass into hydrogen provides a carbon–neutral route to meet energy demand and curb climate change. This paper proposed a novel reactor design that integrated wood particles with a spiral heat-conducting ring to enhance the conversion efficiency of biomass. The effects of wood species and spiral heat-conducting ring parameters were investigated on product concentration and combustion temperature under different operating conditions. The results showed that the increasing of air velocity improved the combustion temperature, and the maximum hydrogen was obtained at 6 cm/s. The syngas production tended to increase as the height of wood particles decreased. Meanwhile, the addition of a Ni spiral heat-conducting ring increased the hydrogen concentration to 11.4 %, indicating a maximum growth rate of 122.6 %. Moreover, when the ring wire diameter decreased, the hydrogen concentration rose first and then declined. And a longer ring height extended the reaction path and increased the syngas yield. The corresponding results provided valuable insights to optimize the reactor geometry and operating conditions.

The development of lightweight, flexible, and multifunctional shielding materials is crucial for mitigating the complex radiation environment in space, comprising high-energy X-rays, protons, and secondary neutrons. In this study, we present a porous composite consisting of polydimethylsiloxane (PDMS), pyridine-functionalized boron nitride nanosheets (Py-BNN), and bismuth iodide (BiI3) for enhanced multi-radiation shielding. Pyridine functionalization improves BNN dispersion in PDMS by enhancing interfacial compatibility, yielding a more uniform filler network. The porous architecture facilitates uniform BiI3 adsorption throughout the matrix, thereby enhancing the attenuation of X-rays. Thermal analysis shows an elevated decomposition onset temperature of 504.3 °C for Py-BNN/PDMS, compared to 475.8 °C for BNN/PDMS and 445.7 °C for pure PDMS, indicating enhanced thermal stability from improved filler dispersion. Infrared thermography further confirms improved thermal conductivity. X-ray shielding results reveal the Py-BNN/PDMS/BiI3 composite exhibits the highest linear attenuation coefficient (4.26 cm−1) and the lowest half-value layer (0.163 cm), outperforming BNN/PDMS/BiI3 and PDMS/BiI3. Proton beam tests also show superior attenuation in Py-BNN/PDMS/BiI3, attributed to the uniform dispersion of Py-BNN in the PDMS porous structures. Overall, the proposed composite achieves lightweight structure, thermal robustness, and effective shielding against multiple radiation types, demonstrating strong potential for next-generation aerospace radiation protection.

An ice-phobic polyurethane (PU) coating from castor oil, modified with 3-aminopropyltriethoxysilane, has been developed. The castor oil-derived silanized polyurethane prepolymer (PreCOPU-Si) was synthesized using controlled reactions and characterized through advanced techniques, in comparison to the unsilanized prepolymer (PreCOPU). Moisture-cured coatings (COPU-Si and COPU) showed successful silane group incorporation. Ice adhesion tests revealed significantly reduced adhesion strength for COPU-Si: 0.2 MPa (normal tension) and 0.05 MPa (shear tension), compared to unmodified COPU (1.2 MPa and 0.17 MPa). Enhanced hydrophobicity was confirmed via water contact angle measurements and freezing studies, demonstrating reduced ice adhesion and stable droplet shapes. COPU-Si exhibited improved mechanical properties and strong adhesion (>10 MPa) to fiberglass (FG), positioning this castor oil-derived silanized polyurethane coating as a sustainable, high-performance solution for ice-phobic applications.

The present work evaluated the efficacy of a Sono-Photo-Fenton technique using ternary vanadate InVO4/BiVO4/FeVO4 for the degradation of tetracycline (TCL), a persistent pharmaceutical pollutant. A comprehensive evaluation of the ultrasound (US), Visible light (Vis-L), and advanced oxidation processes (AOPs) along with H2O2 and InVO4/BiVO4/FeVO4 photocatalysts to elucidate synergistic effects and underlying mechanisms. The photocatalyst was prepared and characterized through several analytical methods, such as FESEM and TEM, and XRD to investigate their morphology and crystal size, revealing an average size of 271.9 nm, which confirms the uniformity of the synthesized particles. The electronic structure and band alignments of the InVO4/BiVO4/FeVO4 photocatalyst were elucidated through DFT simulations, Tauc-plot, and Mott-Schottky (MS) analysis. Further, Electron spin resonance (ESR) analysis provides insights into the charge migration route during the proposed dual s-scheme mechanism. Significant degradation efficiency of 98.28 % was achieved under optimized conditions: H2O2 + InVO4/BiVO4/FeVO4 dosage of 80 mg, ultrasonic frequency of 20 kHz, Vis-L power of 500 W, and a reaction time of 120 min. Degradation kinetics confirmed a pseudo-first-order reaction with rate constant of 0.036 min−1, and the TCL degradation pathway was elucidated by LC-MS analysis, confirming the breakdown of TCL into CO2, H2O, and other inorganic substances. This study highlights the potential of energy-driven irradiation using three techniques US + Vis-L + H2O2-InVO4/BiVO4/FeVO4 i.e., Sono-Photo-Fenton process using ternary vanadate as a promising strategy for the treatment of pharmaceutical contaminants in wastewater, offering insights into the mechanisms of enhanced degradation.

Despite the engineering potential offered by the integration of hybrid (organic and inorganic) materials, organic compounds with metal surfaces, in protecting corrosion-prone metals from harsh conditions, the interaction mechanisms between these components and their in-situ formation to induce nature-inspired composites remain insufficiently understood. In this study, an environmentally friendly organic coating (OC) was developed and applied to carbon steel (CS) substrates via a dip-coating process using an aqueous solution containing 2-amino-4-(4-chlorophenyl)-1-(1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl)-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carbonitrile (oh-HQc) compound. Surface characterization techniques, including SEM-EDX and FTIR, confirmed the successful deposition and chemical integrity of the as-synthesized OC. These results also demonstrate a strong interfacial affinity of oh-HQc molecules for the CS surface, facilitating the nucleation of a petal-like structure through active adsorption sites onto the CS surface. Subsequently, the fundamental formation mechanism governing the nucleation and oh-HQc self-assembly behavior, reactivity, and their adsorption behavior were analyzed based on advanced theoretical calculations. Owing to the oh-HQc donor–acceptor sites, the tested system with three oh-HQc fragments promotes the controlled growth of uniformly distributed flower-like structures via molecular self-assembly and inter/intra-fragmentation interactions. The as-fabricated OC was exposed to different aggressive media, including 1.0 HCl, 3.5 wt% NaCl, and 1.0 M H2SO4 environments to evaluate their electrochemical, short-term/long-term stability, and anticorrosion performance. This flower-like structure demonstrated superior anticorrosion performance, achieving an inhibition efficiency of approximately 95 % in 1.0 M HCl, 90 % in 3.5 % NaCl, and 51 % in H2SO4 environments. Our eco-conscious approach paves the way for a deeper exploration of the structural and functional potential of hydroxyquinoline (HQ) derivatives in the fabrication of advanced organic materials, not only characterized by remarkable properties but also benefiting from facile synthetic methodology, which is of paramount importance for industrial implementation.
尽管混合(有机和无机)材料的集成提供了工程潜力,有机化合物与金属表面,在保护易腐蚀的金属免受恶劣条件下,这些成分之间的相互作用机制和它们的原位形成,以诱导自然启发的复合材料仍然没有充分的了解。本研究以含有2-氨基-4-(4-氯苯基)-1-(1,3-二羟基-2-(羟甲基)丙烷-2-基)-5-氧-1,4,5,6,7,8-六氢喹啉-3-碳腈(oh-HQc)化合物的水溶液为基材,采用浸涂工艺,开发了一种环保型有机涂料(OC),并将其应用于碳钢(CS)基材上。表面表征技术,包括SEM-EDX和FTIR,证实了合成OC的成功沉积和化学完整性。这些结果还表明oh-HQc分子对CS表面具有很强的界面亲和力,通过CS表面的活性吸附位点促进花瓣状结构的成核。随后,基于先进的理论计算,分析了oh-HQc成核和自组装行为的基本形成机制、反应性及其吸附行为。由于oh-HQc供体-受体位点的存在,含有3个oh-HQc片段的系统通过分子自组装和片段间/片段内相互作用促进了均匀分布的花状结构的可控生长。将制备好的OC暴露在不同的腐蚀性介质中,包括1.0 HCl、3.5 wt% NaCl和1.0 M H2SO4环境,以评估其电化学、短期/长期稳定性和防腐性能。这种花状结构表现出优异的防腐性能,在1.0 M HCl环境中达到约95%的缓蚀效率,在3.5% NaCl环境中达到90%,在H2SO4环境中达到51%。我们具有生态意识的方法为深入探索羟基喹啉(HQ)衍生物在制造先进有机材料中的结构和功能潜力铺平了道路,不仅具有显著的性能,而且还受益于简单的合成方法,这对工业实施至关重要。

Flow capacitive deionization (FCDI) is emerging as a promising desalination technology, offering continuous operation, high water recovery (up to 97 %), and lower energy consumption than conventional methods. The performance of FCDI systems is primarily influenced by two critical factors: active electrode materials and flow channel geometries. These elements govern ion transport, charge transfer efficiency, and energy consumption. Although material and channel design improvements are often studied separately, their combined effect plays a pivotal role in optimizing performance and warrants integrated evaluation. This review focuses on recent advancements in both areas, consolidating progress in electrode material innovations and flow channel designs. Reported improvements include enhanced average salt removal rates (∼3.29 μmol cm2 min−1) and energy recovery efficiencies reaching 36 %. By presenting these developments, the review provides insights to guide future research and design strategies, reinforcing FCDI’s potential as a sustainable and scalable solution for high-salinity and large-scale water desalination applications.

A superhydrophobic surface with a hierarchical micro-nano structure was successfully fabricated on a titanium substrate via an economical anodization process using a 0.3 wt% NH4F and 2 wt% C6H8O7 electrolyte solution, followed by subsequent chemical modifications. The influence of anodic oxidation parameters, including oxidation time and voltage, on the morphology and wettability of the superhydrophobic surfaces was systematically investigated and optimized. Experimental results demonstrate that both oxidation time and voltage significantly affect the surface morphology and wettability. By adjusting these parameters, complex hierarchical structures such as nanopores, nanoclusters, micro/nano spherical particles and flower-like micro/nano protrusion structures can be precisely engineered on the titanium substrate. The optimal conditions for achieving a superhydrophobic surface are an oxidation voltage ranging from 30 to 70 V and an oxidation time ranging from 40 to 100 min. Under these conditions, the maximum water contact angle reached ∼163.4°, while the minimum sliding angle was ∼1°. The developed superhydrophobic surface not only exhibits superior anti-corrosion and anti-icing properties but also demonstrates low adhesion to water droplets, outstanding self-cleaning capabilities, and long-term stability.

MXenes, two-dimensional transition metal carbides, nitrides, and carbonitrides, have rapidly emerged as promising multifunctional materials for advanced energy applications owing to their unique combination of metallic conductivity, hydrophilicity, and tunable surface chemistry. MXenes are materials obtained by selectively etching MAX phases (a family of layered compounds) and have desirable properties such as a high surface area, many active sites, and mechanical stability, ultimately making them promising materials for use in energy storage and sustainable systems. Here, we highlighted the most desirable application in energy production and storage devices. Surface termination plays a very important role in enhancing the optical and electrical properties of MXenes. The purpose of this brief study was to evaluate and highlight the advantages and disadvantages of 2D materials, MXenes, by extensively going over the principles and listing the possibilities in this growing field.

Resin-based hard carbon has become an ideal choice for the anode material of sodium-ion batteries due to its tunable microstructure and high sodium storage capacity. However, rational structural modulation to optimize its sodium-ion transport capability and improve its rate performance remains a critical challenge. In this study, a resorcinol–formaldehyde resin precursor was innovatively employed to construct a 3D interconnected spherical hard carbon framework. This structure establishes continuous conductive pathways, significantly enhancing charge transfer kinetics. And particle size variation was achieved through a solvent regulation strategy. Systematic investigations reveal that reducing particle size effectively shortens sodium-ion diffusion distances, leading to enhanced rate capability. The optimized anode demonstrates stable cyclability with capacity retention of 277.6 mAh g−1 after 400 cycles at 0.1 A g−1, while maintaining reversible capacity of 182.9 mAh g−1 after 400 cycles under 0.5 A g−1.
