The Parametrization of Thermoelastic Martensite Phase Transformations at Constant Stress in Shape Memory Alloys Using a Sigmoidal Boltzmann Function The parametrization of the thermomechanical behavior of shape memory alloys (SMAs) under constant load is described in terms of their functional properties. The deformation–temperature–stress behavior of SMAs from various alloy systems—such as Ni-Ti, Ni-Ti-Cu, and Ni-Mn-Ga—was parametrized using a sigmoidal function. This approach enables the characterization of phase transformation parameters, including transformation temperatures, kinetic parameters, and the relationship between recoverable deformation and applied stress. It is shown that the sigmoid function can serve as a universal descriptor of thermoelastic phase transformations across different alloy systems and transformation types, such as B2–R–B19′–R–B2 (Ni-Ti-Cu), B2–R–B19′–B2 (Ni-Ti), and B2 (L21)–B19′ (L20)–B2 (L21). A correlation coefficient of approximately 0.99 was achieved. The present work extends the theoretical framework of diffuse martensitic transitions in SMAs, for which the sigmoid function has been theoretically derived to describe phase fractions. The article’s novelty lies in shifting from pure mathematical approximation (curve fitting) to physical parametrization of SMA behavior specifically under constant stress (actuator mode).

Preparation and Application of pH Self-Controlled Slow-Release Sensor Current smart packaging systems exhibit uneven release of active ingredients (rapid in the early stage and slow in the later stage), resulting in insufficient antibacterial and antioxidant properties. This study developed a pH-autonomous controlled-release sensor using Eudragit L100 and citrate as the matrix, with eugenol as the active component, and constructed a sandwich structure via electrospinning. The sensor can automatically release eugenol as needed in response to pH changes during shrimp storage, while simultaneously enabling visual monitoring of spoilage status. This innovation effectively extends the shelf life of fresh shrimp and provides a novel solution for the on-demand release of active ingredients in food preservation.

Particle size–dependent molecular perturbations induced by copper nanoparticles in marine medaka (Oryzias melastigma): an integrated miRNA–mRNA analysis Introduction Copper nanoparticles (Cu-NPs) have been increasingly released into marine environments due to their extensive applications, posing potential risks to marine organisms and human health. Although Cu-NPs of different particle sizes exhibit distinct toxicities—largely attributed to variations in specific surface area and Cu 2+ dissolution rates—current physicochemical parameters still fail to fully explain these toxic effects, and the underlying molecular mechanisms remain unclear. Methods This study aimed to investigate the toxic effects and underlying molecular mechanisms of Cu-NPs of different nominal primary diameters (10 nm, 50 nm, and 100 nm) on the marine medaka ( Oryzias melastigma ). Results LC 50 point estimates suggested slightly higher toxicity for smaller Cu-NPs. Integrated miRNAomic and transcriptomic analyses revealed that Cu-NPs-10 exposure markedly activated multiple metabolic pathways, including drug metabolism–cytochrome P450, retinol metabolism, and ascorbate and aldarate metabolism. Cu-NPs-50 exposure primarily affected neurodevelopment and synaptic signaling, with predicted miRNA–mRNA associations including miR-202 with mprip-like and miR-2187 with adgrg2-like . In contrast, Cu-NPs-100 exposure activated inflammation- and barrier repair-related networks, with potential miRNA–mRNA relationships involving miR-202 with tm4sf5 , miR-106a, miR-132c, miR-200b, and miR-202 with znfx1 , as well as miR-2187 and miR-202 with rhbdl2 . Discussion Collectively, the integrated miRNA–mRNA analysis suggests that smaller Cu-NPs show a correlation with more intense molecular stress responses than larger particles under seawater transformations (e.g., aggregation/dissolution), and provides insights into the key regulatory networks potentially underlying these size-associated responses.

Ideal band structures for high-performance thermoelectric materials with band convergence We investigate optimal band structures in band-converged systems to achieve high zT using numerical calculations based on a virtual spectral conductivity model. We consider a two parabolic band system, in which multiple band parameters can be independently controlled. Despite its simplicity, this model provides theoretical validation of empirical trends observed in thermoelectric materials. Our results provide a physically transparent set of design principles for band-structure engineering, offering quantitative design guidelines for the development of a wide range of thermoelectric materials. The main conclusions are as follows: (i) When a band does not cross the chemical potential and |μ-E_edge |>5k_B T, the contribution of the band to zT is negligibly small; (ii) To suppress the bipolar effect, a band gap E_g satisfying E_g>5k_B T_op, where T_op is the operating temperature, is required; (iii) In band-converged systems, the energy separation between the band edge ΔE should satisfy ΔE~0 to maximize zT when interband scattering is insignificant; (iv) Achieving high spectral conductivity Σ (high band degeneracy N, density of states effective mass m_DOS^*, and relaxation time τ) near the band edge is essential for achieving high zT.

Colloidal Magnus effect in polymer solutions Rotating particles moving in fluids undergo a transverse migration via the inertia-induced Magnus effect. This phenomenon vanishes at colloidal scales because inertia is negligible and the fluid flow is time reversible. Yet, recent experiments discovered an inverse Magnus effect of colloids in polymeric and micellar solutions, supposedly because their viscoelasticity breaks the time reversibility. Our study shows that classical viscoelastic features—stress relaxation, normal-stress differences, and/or shear thinning—cannot explain this phenomenon. Instead, it originates from local polymer density inhomogeneities due to their stress-gradient-induced transport, a mechanism increasingly important at smaller scales—indeed, relevant to colloidal experiments. Incorporating this mechanism into our model leads to quantitative agreement with the experiments without fitting parameters. Our work provides new insights into colloidal motion in complex fluids with microstructural inhomogeneities, offers a simple mechanistic theory for predicting the resulting migration, and underscores the necessity of assimilating these findings in future designs of micro-machinery, such as those including swimmers, actuators, or rheometers.

Chitosan-essential oil Pickering emulsion coating for improving microbial safety of traditional food packaging based on banana leaves Traditional packaging in Indonesia often uses leaves, with banana leaves favored for their cultural value, biodegradability, and flavor enhancement, however their lack of biofunctional properties limits preservation performance. This study aimed to evaluate the antimicrobial activity of various chitosan/Tween 80/cellulose nanocrystals/cinnamon/lemongrass essential oil coatings, and further assessed their efficacy in vivo using banana leaf-wrapped serabi , a representative Indonesian traditional food. Edible coating formulations were prepared using emulsions containing 0.5% CEO or LEO stabilized with either 0.05% nanocellulose or 0.3% Tween 80. Microbial activity showed that Pickering emulsified chitosan with cinnamon essential oil had the highest inhibition zone of 21.59 ± 0.2 mm on Escherichia coli, 14.27 ± 0.13 mm on Pseudomonas aeruginosa, 19.21 ± 0.24 mm on Bacillus subtilis, and 27.42 ± 0.40 mm on Staphylococcus aureus. The coated banana leaf was able to maintain the shelf life of serabi up to 12 h according to the Indonesian Food and Drug Authority (BPOM) standard without providing differences with the control confirmed by the triangle test. This method offers a sustainable alternative technology that maintained consumer acceptance while supporting traditional eco-friendly packaging practices.

Salinity stress mitigation in tomato (Solanum lycopersicum L.): mechanisms, impacts and copper nanoparticle based solution Salinity stress is a major abiotic factor that severely limits global crop productivity. It disturbs plant water relations, ion homeostasis and redox balance, leading to reduced plant growth and productivity. Conventional practices have only partially alleviated these constraints, especially in the rapidly expanding salt-affected areas, driven by climate change and unsustainable irrigation practices. In this context, copper-based nanoparticles (Cu-NPs) have emerged as promising nano-agrochemicals, capable of modulating multiple stress-responsive pathways. This review summarizes the current knowledge on the morpho-physiological, biochemical and molecular mechanisms implicated in salinity tolerance in tomato and critically evaluates how Cu based nanoparticles modulate cellular homeostasis to improve salt resilience. Evidence from physiological, biochemical and ionic studies indicates that Cu based nanoparticles stabilize cellular metabolism under saline conditions, by strengthening antioxidant defense, improve Na<sup>+</sup> exclusion and K<sup>+</sup> retention and protect photosynthetic performance. Proteomic investigations further reveal that in Cu-NP-treated tomato plants, the aforementioned cellular alternations are coordinated through stress signaling proteins and involve energy metabolism. Thus, providing a mechanistic basis for the observed phenotypic benefits. Genotype as well as concentration dependent responses emphasize that Cu-NP efficacy is maximized at intermediate doses under moderate stress, while excessive application can trigger copper toxicity and redox imbalance. The review also discusses potential environmental risks, regulatory gaps and standardization challenges associated with deployment of copper-based nanoparticles under field conditions. By integrating multi-scale evidence, the review provides a conceptual framework for rationally designing Cu-NP based interventions and identifies key research priorities for their safe and effective use in tomato cultivation.

Harnessing Oman's Basalt Resources for Economic Diversification: A Strategic Roadmap for High-Value Manufacturing and Clean Energy Applications In line with its Vision 2040 goals for economic diversification, the Sultanate of Oman holds extensive but largely untapped basalt reserves. This study presents a screening-level techno-economic analysis and strategic roadmap for transforming this indigenous resource from a low-value commodity into a cornerstone of a high-value and sustainable industrial ecosystem. The research methodology integrates a quantitative analysis of Oman's current basalt sector with a formal comparative economic model to quantify the potential for value addition. The study highlights a stark economic contrast: exporting raw basalt earns only about $7.30 per tonne, while converting it into Basalt Fiber Reinforced Polymer (BFRP) rebar can generate over $2,500 per tonne. The analysis shows a conservative value increase of more than 300 times, with a preliminary Life Cycle Cost Analysis (LCCA) demonstrating that BFRP significantly outperforms traditional steel economically in infrastructure projects. It also confirms that Omani basalt from the Samail Ophiolite is exceptionally well-suited for producing advanced fibers. Furthermore, this paper identifies and discusses a parallel strategic opportunity for Oman to leverage these same geological formations for large-scale, permanent carbon sequestration with the potential for clean hydrogen co-generation. The paper concludes by proposing a phased strategic roadmap for Oman, recommending the prioritized development of an integrated BFRP rebar value chain while initiating research into basalt-based climate technologies, thereby positioning the Sultanate as a future regional leader in both advanced green materials and the global energy transition.

Визначення впливу їстівного желатинового, агар-агарового та хітозанового покриття на збереженість плодів огірка This study examines the technology of pre-treating cucumber fruits using edible coatings based on gelatin, agar-agar of various concentrations, as well as chitosan with the addition of garlic essential oil. The task addressed is to identify safer and more effective post-harvest treatment technologies for cucumbers, which could reduce produce losses during storage and extend their shelf life. The materials under investigation were cucumber fruits, gelatin, agar-agar, chitosan, as well as garlic essential oil. The ratio of gelatin to agar-agar in the coating matrix gelatin:agar-agar was 100%:0; 0:100; 75%:25%; 50%:50%; and 25%:75%, with chitosan at 1%. The influence of this coating on water-holding capacity, physicochemical, structural-mechanical, and microbiological parameters of cucumber fruits was evaluated. It was established that treatment with edible compositions significantly (НІР05 = 0.79) reduces natural weight loss of cucumbers during storage at a temperature of 15±1°C to a range of 3.1% to 3.6%. Weight loss in untreated fruits amounted to 4.7%. The agar-agar-based coating provided the lowest weight loss of 3.1%. It was shown that daily weight loss of cucumbers ranged from 0.63% to 0.75% when treated with edible compositions. Untreated fruits lost up to 1.37% of their weight daily. The addition of 2% garlic essential oil to the coating inhibited the development of microorganisms by 1.5–1.7 times. The study found that after 6 days of storage, the coated fruits exhibited 11.2% higher elasticity than the control group, and 18.5% higher at the end of the storage period. The effectiveness of the edible coating was confirmed by correlation coefficient r = 0.9317–0.9881 Coating ; Chitosan ; Gelatin ; Essential oil ; Weight loss ; Shelf life Nanocomposite Films for Food Packaging ; Food Industry and Aquatic Biology ; Plant Growth Enhancement Techniques

Iron Oxide Nanoparticles Enabled Ultrasound-Guided Theranostic Systems The tumor microenvironment, characterized by higher acidity, hypoxia, and dense cellular structures, plays a pivotal role in cancer progression, therapeutic resistance, and treatment response. Nanoparticle-based contrast agents enable the precise delineation of solid regions within heterogeneous tumors through advanced molecular imaging techniques. Since 1956, ultrasound (US) medical imaging has provided essential anatomical and functional insights about internal organs. More recently, magnetomotive ultrasound (MMUS) has emerged as a promising imaging modality, using a modulated magnetic field to exert force on superparamagnetic iron oxide nanoparticles (SPIONs), inducing motion in the surrounding tissues through mechanical coupling. In parallel, magnetic hyperthermia (MH), which employs localized heating by alternating magnetic fields, has demonstrated significant potential in selectively destroying cancer cells while sparing healthy tissues. This review summarizes the current state of IONP-based contrast agents, with particular emphasis on their use in MH for cancer treatment, as well as their potential in multimodal imaging, including MMUS, and photoacoustic (PA) imaging. The advantages and limitations of IONPs in tumor detection and characterization are discussed, examining the development of surface-functionalized MNPs, and analyzing how material properties and environmental factors affect their diagnostic and therapeutical performance. Finally, strategies for combining MMUS and PA modalities for pre-clinical cancer imaging are proposed.

Dynamic strain-gradient-induced polarization and nonlinear electromechanical coupling in noncentrosymmetric quantum oxide crystals This study investigates dynamic strain-gradient-induced polarization and nonlinear electromechanical coupling in a noncentrosymmetric wide-bandgap oxide single crystal. The objective was to experimentally verify enhanced dynamic polarization mechanisms beyond classical flexoelectric descriptions and to correlate the results with continuum-level numerical modeling. High-quality single crystals were structurally verified by X-ray diffraction, followed by dynamic polarization measurements over a frequency range from 10 Hz to 1 MHz. Controlled strain gradients were introduced via three-point bending, and nonlinear susceptibility was extracted using harmonic analysis. Finite-element simulations were performed to reproduce spatial polarization distributions under identical boundary conditions. The polarization amplitude exhibited a low-frequency plateau of approximately 4.8 µC/m² and decreased to 3.48 µC/m² at 1 MHz, indicating dispersive dynamic behavior. Under applied strain gradients up to 3 × 10³ m⁻¹, polarization increased from 4.76 µC/m² to 7.81 µC/m², demonstrating nearly linear scaling with higher-order enhancement at larger gradients. A quadratic nonlinear response was confirmed, with second-harmonic polarization reaching 2.052 µC/m² at 100 kV/m. Temperature variation from 20 K to 400 K produced monotonic damping without phase-transition anomalies. Numerical modeling reproduced experimental amplitudes and revealed pronounced spatial localization of polarization. The results confirm robust dynamic electromechanical coupling exceeding classical continuum expectations and establish strain-gradient-driven polarization as a stable and tunable mechanism in noncentrosymmetric quantum crystals. The investigated material was wurtzite ZnO (P6₃mc) with a direct bandgap of approximately 3.3–3.4 eV at room temperature.
