Natural fiber-reinforced composites (NFRCs) have become vital in various engineering applications due to their exceptional properties and ease of manufacturing. Properties such as lightweight, sustainability, design flexibility, microstructure, durability, and advanced fabrication techniques have expanded their use across industries. Also, NFRCs are preferred because the extensive reliance on synthetic fibers presents significant challenges in recycling and waste management. Despite their excellent properties, NFRCs have three main challenges: fiber degradation, water degradation, and weak interfacial strength (incompatibility of fibers with the matrix). Consequently, research efforts have been directed at combating these challenges using different surface treatment techniques. However, research has been skewed towards experimental approaches for improving the interfacial strength in plant fiber polymer matrix composites (PMCs). Hence, there exists a dearth of information on the computational approaches for optimizing the interfacial properties of NFRCs. Hence, this review provides experimental and computational approaches (machine learning) for comprehensive optimizing strategies for different natural fibers (plant, animal, and microorganism) and matrices (polymers, metals, and ceramics). This review also highlights the importance of theoretical approaches and numerical modeling in analyzing and optimizing NFRCs. Finally, the review highlights recent advancements in NFRCs, their mechanical properties, potential applications, and future directions. © 2025 The Authors

Recent advances in natural fiber reinforced metal/ceramic/polymer composites: An overview of the structure-property relationship for engineering applications

Hybrid Advances

Hybrid Advances 2025年 8卷

Advances in the material science world drive the birth of a new generation of sustainable materials. Natural fiber (NFs) biocomposites are emerging as valuable alternatives to conventional materials for engineering applications such as construction, automobiles, and aerospace due to their exceptional mechanical properties, lightweight, low carbon footprint, energy efficiency, and cost-effectiveness. These outstanding properties have made them more desirable for engineering applications. However, the focus has been on lignocellulosic fibers, neglecting other sources, such as keratinous, fibrinous, and microorganism fibers. Only a few reviews have considered the structure-property relationship of all classes of natural fibers, such as lignocellulosic (plant), keratinous and fibrinous (animal), and microorganism (mycelium) fibers. Although NFs have outstanding potential from an economic, technical, environmental, and green credentials perspective, they have limitations, such as fiber-matrix incompatibility and moisture damage. These limitations make using NFs as reinforcement for different material systems challenging. Surface alterations are usually necessary to improve the adherence between fiber and matrix. With the upgrade, NFs have the potential as sustainable replacement for conventional materials for engineering applications. Future research should aim at reconciling the mechanical properties of NFs to improve composite quality and fiber-matrix adherence and performance. © 2025 The Authors

Aluminum–sulfur (Al–S) batteries catalysts with adsorption and catalytic capabilities can effectively improve the slow redox kinetics, but the current research often ignores the effect of optimizing the electronic structure of the catalyst on improving charge transfer and adsorption. Here, Ni-doped monolayer MoS₂ nanosheets are synthesized and used as a catalytic additive for the sulfur cathode. The addition of Ni promotes spin splitting of 4d orbital of Mo, thereby affecting polarization degree of the basal plane sulfur and making it change from a low spin state to a high spin one. This high spin configuration raises the electron energy level and provides an active electron state to react with aluminum polysulfides (AlPSs), which optimizes the adsorption energy. At the same time, it accelerates electron transfer and lowers the energy barrier for the overall conversion of the polysulfides. Benefiting from these features, Al–S batteries based on rationally designed S@Ni-MoS₂/C cathodes exhibit a high initial capacity (1603.0 mAh g⁻¹ at 0.5 A g⁻¹) and extraordinary cycling stability (0.035% capacity decay rate during 2000 cycles). This study showcases a spin-polarized electronic structure control strategy to enhance catalytic activity, providing a viable approach for developing efficient catalysts for practical Al–S batteries. © 2025 Wiley-VCH GmbH.

This work explores the use of photosynthesized coccoliths (intricate CaCO3 particles) as a nucleation agent or cement replacement in portland cement paste. First, coccoliths were produced and harvested from the marine microalgae Emiliania huxleyi and the particle size, morphology, and mineralogy were characterized. Then, the nucleation effects of E. huxleyi coccoliths as seeding agent (0.5, 1, 3, or 5 wt % additions) and limestone filler (5 and 15 wt % cement replacements) were studied using isothermal conduction calorimetry and compressive strength testing. The results were compared with five commercially available CaCO3 sources used as nucleation agents and fillers. While the high surface area of coccoliths (12.22 m2/g) enhanced water demand, it also enhanced nucleation during cement hydration without accelerating hydration, leading to enhanced early-age strength without detriments to 28-day strength. Results highlight a potential carbon reduction strategy, namely employing photosynthesis as a method of mineral admixture production, for the cement and concrete industry. © 2025 Elsevier Inc.

Room-temperature ionic liquids (RTILs) have emerged as potential next-generation lubricants owing to their unique physico-chemical properties and promising lubricating behavior. However, their implementation in tribological applications has partly been hindered by their negligible solubility in hydrocarbon fluids. Here, encapsulated ionic liquids (ENILs) with a core of 1-hexyl-3-imidazolium bis(trifluoromethylsulfonyl)imide ([HMIM][TFSI]) and a composite shell of polyurea/graphene oxide were prepared via Pickering emulsion-templated interfacial polymerization using two approaches, namely an RTIL-in-water emulsion stabilized with graphene oxide (GO) nanosheets ([HMIM][TFSI]/GO) and an RTIL-in-oil emulsion-stabilized with octadecylamine-functionalized GO nanosheets ([HMIM][TFSI]/C18-GO). The synthesized ENILs were successfully dispersed in polyalphaolefin (PAO) synthetic oil and used as additives to lubricate 52100 steel-vs.-52100 steel sliding contacts. Tribological tests provided evidence that the addition of [HMIM][TFSI]/C18-GO and [HMIM][TFSI]/GO ENILs to PAO could reduce friction and wear owing to the release of the encapsulated [HMIM][TFSI] at the sliding interface after the mechanical breakage of the shell material at the contact inlet, but only if a significant fraction of the ENILs has a diameter smaller than 20 µm. Comparison of these results with the outcomes of sliding experiments performed with PAO containing ENIL obtained by mini-emulsion polymerization with poly(ethylene glycol dimethacrylate-co-buytl methacrylate) (poly(EGDM-c-BMA)) shells highlights the role of the shell material in reducing friction. These outcomes not only demonstrate that multiple parameters (i.e., size distribution, shell material) affect the tribological performance of ENILs, but also pave the way towards further systematic investigations for optimizing ENILs to be used as additives in oil formulations. © 2025 Elsevier B.V.

The high cost of gallium has driven interest in aluminum-doped zinc oxide (AZO) as a cost-effective alternative to gallium-doped zinc oxide (GZO). While prior studies have primarily focused on sputtering methods to compare AZO and GZO, research on non-sputtering techniques remains limited. Our previous works demonstrated favorable optoelectronic properties in GZO films deposited via atmospheric pressure plasma jet (APPJ);however, APPJ-deposited AZO has yet to be explored. In this study, we compare AZO and GZO thin films fabricated by APPJ under ambient conditions. We find that the deposition rate of AZO is approximately twice that of GZO under the same processing parameters, due to differences in droplet size from the ultrasonic generator. By adjusting precursor delivery and working distance (the nozzle-to-substrate gap), we can tune film thickness, morphology, and optoelectronic properties, showcasing APPJ's versatility over sputtering. Despite similar precursor concentrations and film thickness, AZO films exhibit lower carrier concentration (∼1 ×1020 cm–3) and mobility (∼7.5 cm2/Vs) than GZO (∼8 ×1020 cm–3 and ∼15 cm²/Vs), attributed to reduced aluminum incorporation (∼0.4 at% vs. ∼2.2 at% in GZO). Reducing the working distance from 2 mm to 1.5 mm improves both films’ structural integrity and optoelectronic performance (figure of merit increases by 140 % for GZO and 100 % for AZO). However, AZO remains inferior to GZO, highlighting the need for further optimization. © 2025 Elsevier B.V.

The mechanical properties of lithium-ion batteries (LIB) are closely related to their state-of-charge (SOC) and state-of-health (SOH). Here, we introduce an in-operando acoustic technique based on acoustic impedance spectroscopy (AIS) which probes the mechanical changes that occur in the LIB during operation. Using thin, inexpensive piezoelectric resonators and widely available impedance analyzers, we can identify the acoustic resonances of commercial LIBs by measuring the complex electrical impedance of the resonator. In-operando AIS shows that these resonances are dependent on the bulk mechanical properties of the LIB, which change reversibly as the cell is cycled. We show that this technique can provide substantial information on both the SOC and SOH of a commercial LIB.

The impurity sulfur embrittlement of Ni-based single superalloys (Ni-SXs) has long been wrapped in mystery. In this work, we report for the first time the sulfur-induced precipitation of brittle rhenium-rich δ phase in a model Ni-SX. The results showed that the addition of sulfur gave rise to the precipitation of rhenium-rich δ phase with hexagonal close-packed (HCP) crystal structure in the dendritic cores. Besides, the enrichment of sulfur and nickel elements were detected in the δ phase. The behavior of sulfur-induced precipitation of δ phase was rationalized by the first-principles calculations, which indicates that there is a strong bonding interaction between sulfur and rhenium atoms. This work provides a novel perspective on the understanding of the sulfur embrittlement in Ni-SXs. © 2025, The Authors. All rights reserved.
