Fuzzy-Ball Fluids: Fundamentals, Mechanisms, and Prospects for Clean Energy and Oilfield Applications Fuzzy-ball fluids have emerged as a novel class of chemical sealaplugging materials with significant potential for enhancing both traditional oilfield operations and clean energy technologies. They are characterized by unique viscoelastic properties, plugging, self-adapting capabilities, and the ability to regulate multi-phase fluid flow under extreme subsurface conditions. In oilfield applications, fuzzy-ball fluids offer solutions for drilling, hydraulic fracturing, workover operations, and enhanced oil recovery in shallow, deep, and offshore reservoirs. In clean energy fields such as hydrogen storage, carbon capture, utilization, and storage, and geothermal energy, they show promise in improving energy efficiency, storage security, and environmental sustainability. This review explores the fundamental principles and mechanisms behind fuzzy-ball fluids, examines their field applications in the oil and gas industry, and investigates their potential in emerging clean energy technologies. This study also identifies key challenges, including material stability, economic viability, and environmental impact, which must be addressed to ensure the successful deployment of fuzzy-ball fluids. Furthermore, we outline future research directions, emphasizing material optimization, large-scale field trials, environmental impact assessments, and interdisciplinary collaboration to accelerate the commercialization of fuzzy-ball fluid technologies. By addressing these challenges, fuzzy-ball fluids could play a transformative role in both conventional and clean energy fields, contributing to sustainable and efficient energy solutions.

Biocompatible β-cyclodextrin-based metal-organic frameworks β-Cyclodextrin (β-CD) is a cyclic heptasaccharide, part of the family of molecules which are widely used in several biological applications. The unique cone-shape of cyclodextrins with multiple binding sites make them a well-suited building block for constructing porous crystalline solids, such as metal-organic frameworks (MOFs). However, owing to the symmetry constraints, progress in the coordination chemistry of β-CD with alkali and alkaline earth metal cations has been limited and there is less understanding of this chemistry compared to its analogues of α-CD and γ-CD. In this work, synthetic conditions were optimised to obtain two MOF structures with β-CD as the organic linker, one each with Na<sup>+</sup> and K<sup>+</sup> cations. As well as structural determination, detailed solid-state characterization is reported for both the MOFs. The structure analysis helps shed light on the binding tendencies of β-CD and these structures will further facilitate the deployment of biocompatible building blocks for the development of reticular solid materials.

Synchronous Measurement of Temperature and Rotational Speed by Color‐Tunable Mechanoluminescent Material ABSTRACT Monitoring temperature and rotational speed in extreme environments is a persistent challenge for conventional systems, which rely on separate electronic sensors and are prone to failure. To overcome this, we introduce a self‐power multimodal detection system for synchronous sensing of both parameters, enabled by a novel thermo‐sensitive color‐tunable mechanoluminescent material Cs 3 GdGe 3 O 9 :Tb 3+ , Eu 3+ , Na + . The maximum relative sensitivity is up to 4.5% K −1 , which is the most sensitive temperature‐sensing mechanoluminescent material to date. Crystallographic defect engineering facilitates energy transfer between rare‐earth ions, which enables the originally monochromatic mechanolumnescent material with temperature‐dependent variable colors. This work opens an avenue for the design of thermosensitive multi‐color mechanoluminescent materials and provides new strategies for integrated sensors.

Defect-induced interfacial modulation for enhanced resistive switching performance in antiferroelectric/ferroelectric heterostructures Resistive switching devices, particularly memristors, have attracted considerable interest due to their promising applications in neuromorphic computing and data storage. However, achieving high performance and reliability remains a significant challenge, especially in the optimization of their ferroelectric and switching properties. In this study, we report a substantial enhancement of both resistive switching and ferroelectric properties in NaNbO3 (NNO)/PbTiO3 (PTO) multilayers, facilitated by interfacial modifications of the electronic structure induced by defects and strain. The well-defined interfaces and strain gradients within the PTO layers lead to substantial alterations in local electronic properties, including Ti 3d orbital hybridization and oxygen octahedral tilting. These structural modifications enhance charge trapping dynamics, resulting in an ON/OFF ratio of 104, compared with 102 in single-layer NNO films. The synergistic effects of enhanced polarization and electronic state modulation are shown to optimize both the ferroelectric and resistive switching behaviors, highlighting the pivotal role of interface engineering in achieving high-performance memristive devices.

High Magnetic Sensitivity at the Coercive Field Induced by Shear Horizontal SAW in Polycrystalline FeGa Films Abstract A Love wave device is designed to generate surface acoustic waves (SAWs) with strong shear‐horizontal polarization, interacting with a polycrystalline Fe 72 Ga 28 magnetostrictive layer. The shear strain induced by these waves at a frequency of ≈160 MHz, coupled with magnetoelastic effects, leads to domain magnetization oscillation, resulting in unique responses that are particularly pronounced near the coercive field. Experimental results reveal that the response of the sensor is highly sensitive to the angle between the applied magnetic field and the wave propagation direction, with profiles that can vary significantly depending on this angle, with some configurations resulting in practically opposite responses. A particularly relevant case arises when the magnetic field is aligned with the Love wave propagation direction. In this case, the sensor response shows mainly a monotonic increase with the magnetic field, except near the coercive field, where a sharp peak emerges and then abruptly collapses, resulting in a magnetic sensitivity of ≈5 Hz/nT (0.031 ppm nT −1 ). This high sensitivity near the coercive field opens the door to the development of high‐performance sensors, simplifying electronics while leveraging the key advantages of SAW technology, including low power consumption, compact size, real‐time response, and portability. A theoretical model is also discussed to further understand the underlying phenomena and optimize the design of next‐generation devices, which hold significant potential for sensor applications across various fields.

Application of Hansen Solubility Parameters in the Aqueous-Ethanol Extraction of Genistein-7-O-[α-rhamnopyranosyl-(1→6)]-β-glucopyranoside from Derris scandens and Its Molecular Orbital Study on Antioxidant Activity This study explored the extraction of genistein-7-O-[α-rhamnopyranosyl-(1→6)]-β-glucopyranoside (GTG) from <i>Derris scandens</i> using an aqueous-ethanol solvent system, aiming to optimize yield and antioxidant activity. Hansen solubility parameters (HSP) were employed to determine the optimal solvent composition, with the highest GTG yield (6.83 ± 0.06 mg/g dried weight) obtained from 50% ethanol-correlating well with HSP predictions. Ultrasonic extraction was most effective with solvents having a dielectric constant between 50 and 60. The antioxidant potential of isolated GTG was evaluated using the DPPH assay, which yielded an IC<sub>50</sub> of 87.86 ± 1.85 μM, and the FRAP assay, with a value of 34.23 ± 2.75 mg FeSO<sub>4</sub> equivalents. Molecular orbital analysis revealed HOMO and LUMO energy gaps (ΔE = 10.6715 eV) similar to known antioxidants such as gallic acid, ascorbic acid, Trolox, and quercetin. These findings demonstrate that HSP effectively guided solvent selection for ultrasound-assisted extraction of GTG. The antioxidant activity is attributed to GTG's capacity to donate electrons and stabilize radicals via extended charge delocalization within the aglycone structure, confirming its potential as a natural antioxidant agent.

Comparative Role of rGO, AgNWs, and rGO–AgNWs Hybrid Structure in the EMI Shielding Performance of Polyaniline/PCL-Based Flexible Films The present study explores the comparative influence of reduced graphene oxide (rGO), silver nanowires (AgNWs), and their hybrid rGO-AgNWs on the electromagnetic interference (EMI) shielding performance of polyaniline (PANI)-based flexible films prepared using a polycaprolactone (PCL) matrix. The nanocomposites were synthesized through in situ oxidative polymerization of aniline in the presence of individual or hybrid fillers, followed by their dispersion in the PCL matrix and casting of the corresponding films. Morphological and structural characterization (SEM, Raman, and FTIR spectroscopy) confirmed a uniform PANI coating on both rGO sheets and AgNWs, forming hierarchical 3D conductive networks. Thermal (TGA) and thermomechanical (TMA) analyses revealed enhanced thermal stability and stiffness across all composite systems, driven by strong interfacial interactions and restricted polymer chain mobility. Tmax increased from 437.9 °C for neat PCL to 487.9 °C for PANI/PCL, 480.6 °C for PANI/rGO/PCL, 499.4 °C for PANI/AgNWs/PCL and 495.0 °C for the hybrid PANI/rGO-AgNWs/PCL film. The gradual decrease in contact angle following the order PANI/AgNWs/PCL < PANI/rGO-AgNWs/PCL < PANI/rGO/PCL < PANI/PCL < PCL clearly indicates a systematic increase in surface polarity and surface energy with the incorporation of conductive nanofillers. Electrical conductivity reached 60.8 S cm<sup>-1</sup> for PANI/rGO/PCL, gradually decreasing to 27.4 S cm<sup>-1</sup> for PANI/AgNWs/PCL and 22.1 S cm<sup>-1</sup> for the quaternary hybrid film. The EMI shielding effectiveness (SET) measurements in the X-band (8-12 GHz) demonstrated that the PANI/rGO/PCL film exhibited the highest attenuation (~7.2 dB). In contrast, the incorporation of AgNWs partially disrupted the conductive network, reducing SE to ~5-6 dB. The findings highlight the distinct and synergistic roles of 1D and 2D fillers in modulating the electrical, thermal, and mechanical properties of biodegradable polymer films, offering a sustainable route toward lightweight, flexible EMI shielding materials.

Advanced post-treatment strategy for quantum-grade fluorescent nanodiamonds Fluorescent nanodiamonds (FNDs) containing nitrogen-vacancy (NV − ) centers are promising platforms for quantum sensing and bioimaging, but their performance is often limited by surface defects, residual graphitic carbon, and ionic contamination. Here, we report a multistep surface treatment strategy combining molten potassium nitrate (KNO 3 ) thermal oxidation with sequential acid and alkaline cleaning to produce high-quality, quantum-grade FNDs. Molten KNO 3 etching at 580 °C enables morphological reshaping and partial oxidation, while subsequent H 2 SO 4 /HNO 3 , NaOH, and HCl washes eliminate graphitic residues, neutralize surface charges, and remove metal ions. This protocol yields discrete, colloidally stable FNDs with enhanced photoluminescence, a high ODMR contrast of 11.5%, and extended average spin-lattice relaxation time (T 1 ≈ 2045 µs). Dynamic light scattering and ζ-potential measurements confirm excellent dispersion (∼100 nm, −30 mV). The integration of chemical, morphological, and spin-performance improvements establishes a scalable route for producing FNDs suitable for high-fidelity quantum sensing and biophotonic applications.

Diving into commercial cellulase formulations for circular polyester/cotton separation through targeted depolymerization of cotton The rapid growth of the textile industry, driven by fast fashion trends, has significantly increased textile waste, particularly blends of polyester (PET) and cotton fibers, and efficient recycling of blended textiles requires effective fiber separation methods, yet current strategies face substantial limitations. This study investigates the performance of commercially available cellulase formulations for enzymatic depolymerization of cotton and suggests an optimized activity pattern for novel reactor systems for recycling of PET/cotton blends. Thirty-five cellulase formulations intended for biopolishing, stonewashing, or biomass degradation were extensively characterized through biochemical assays (protein quantification, reducing sugar content, SDS-PAGE, and enzyme-specific activity assays). The formulations were further categorized according to their physical state, optimal pH and temperature class, and use case (biopolishing, stonewashing, and degradation), and trends were observed between the categories. Ten formulations were selected for further practical evaluation in a controlled reactor system to determine cotton removal efficacy from a blended PET/cotton fabric based on cotton weight loss. Enzyme activity assays did not correlate directly with reactor performance, suggesting that conventional cellulase assays may inadequately predict real-world separation efficiency. Protein efficiency was introduced as a critical metric for evaluating enzyme efficacy and economic viability. Here this variable was defined as a specific activity, relating the fiber separation efficiency in the reactor to the protein content of the formulation to indicate how effective the proteins were at separation. Formulations exhibiting balanced high performance in both weight loss and protein efficiency predominantly contained high proportions of endoglucanase activity, supported by moderate cellobiohydrolase and minor beta-glucosidase activities.
