Identification of drivers of global trade in plastic waste based on GCA and ISM-MICMAC model: Taking China, USA and South Africa as cases.

Plastic waste's dual characteristics of "resource" and "pollution" led to the prevalence of trade. The Global Plastic Waste Trade Network (GPWTN) is heterogeneous, and its structure is susceptible to the influence of key countries within it. However, there is a shortage of research on the key countries and trade drivers influencing GPWTN evolution. In this paper, three typical countries (China: importer - exporter; USA: exporter; South Africa: potential importer) are selected as cases. Through an extensive literature review, a comprehensive set of 22 trade drivers (TDs), including economic and social factors, environmental pressure, plastic industry, plastic waste, and policy, were identified and then evaluated and ranked using the Grey Relational Analysis (GRA) method. The results reveal that the TDs with the highest trade relevant to China are environmental taxation and NOx (Grey relation correlation, GRC=0.84). The USA was influenced by the environmental policy stringency index (GRC=0.69) and South Africa by the environmental taxation of waste and plastic products (GRC=0.91). This shows that carbon trading policies have become the highest impact driver on the USA's plastic waste trade. The coupled ISM-MICMAC (Interpretive structural modelling-Cross-Impact Matrix Multiplication Applied to Classification) method was used to identify the relationship between trade and drivers and to explore the TDs of different countries. The identified TDs are influenced by policies. The policies to reduce plastic waste production and primary plastic use, to achieve zero plastics in landfills, and to control CO2 emissions could cut the amount of plastic waste exported from China. Both multi-driver controls and single-CO2 emission controls could significantly reduce plastic waste exports, with reductions exceeding 94% in 2060. Controlling CO2 emissions would be the best option for China. For South Africa, the multi-drivers and recycling scenarios could reduce import rates by 70.83% and 66.3% in 2060. In South Africa, the implementation of policies to increase recycling rates, taxing plastics and plastic waste, etc. is the optimal choice to reduce imports.

Pelagic shark intestine as a potential temporary sink for plastic and non-plastic particles.

Highly migratory pelagic sharks have the potential to serve as carriers of particle contamination in a vast three-dimensional space. We investigate the occurrence, abundance and characteristics of plastic and non-plastic particles in the scroll intestine of the blue shark (Prionace glauca), one of the most abundant pelagic shark species worldwide. We detected both plastic and non-plastic particles in all sections of the intestine, with the posterior region exhibiting the highest concentration. We estimated that individual intestine may contained 11.21±9.62 and 48.00±23.90 plastic or non-plastic particles, respectively. Fibers dominated particle morphology (95.58%), primarily composed of plastic polymers (polyester and polyethylene terephthalate) (plastic) and non-plastic material (rayon and cotton). Given their size range (102.08-8113.54μm), these particles are likely to be released into the water column through excretion. The intestine of P. glauca may act as a temporary particle sink, a phenomenon potentially common among pelagic sharks worldwide. This study provides new insights for the role of highly migratory fish species in the transport and distribution dynamics of marine particle contamination.

Simulating Neuromorphic Behavior in Memory Devices with Special Ions: Insights into Device Performance and Predictive Modeling.

The development of neuromorphic memory, which mimics the computational processes of the brain, offers exciting prospects for applications in advanced computing. This studyassesses the potential of metal-ion-containing polyvinyl acetate (PVAc) fiber as neuromorphic memory devices. To assess the synaptic plasticity and hysteresis characteristics of the manufactured devices, they underwent a thorough electrical characterization process that included currentvoltage (I-V) testing and pulse stress analysis. With long-term depression (LTD) under negative stress (-6V) and long-term potentiation (LTP) under positive stress (+6V), the results showed that PVAc + metal-ion devices display dual-direction plasticity. The plasticity zones showed good adaptability in simulating neuronal learning and forgetting mechanisms, extending up to approximately 300 seconds for LTP and 500 seconds for LTD.These results demonstrate that PVAc + metal-ion devices can be used in neuromorphic applications, especially for energyefficient adaptive memory systems in robotics, artificial neural networks, and edge computing. Although there is promise for neuromorphic applications with these devices, further work is required to overcome their sensitivity to external factors. This work opens the door for future neuromorphic systems and provides important insights into device performance.

Plastic pollution and marine mussels: Unravelling disparities in research efforts, biological effects and influences of global warming.

The ever-growing contamination of the environment by plastics is a major scientific and societal concern. Specifically, the study of microplastics (1μm to 5mm), nanoplastics (< 1μm), and their leachates is a critical research area as they have the potential to cause detrimental effects, especially when they impact key ecological species. Marine mussels, as ecosystem engineers and filter feeders, are particularly vulnerable to this type of pollution. In this study, we reviewed the 106 articles that focus on the impacts of plastic pollution on marine mussels. First, we examined the research efforts in terms of plastic characteristics (size, polymer, shape, and leachates) and exposure conditions (concentration, duration, species, life stages, and internal factors), their disparities, and their environmental relevance. Then, we provided an overview of the effects of plastics on mussels at each organisational levels, from the smaller scales (molecular, cellular, tissue and organ impacts) to the organism level (functional, physiological, and behavioural impacts) as well as larger-scale implications (associated community impacts). We finally discussed the limited research available on multi-stressor studies involving plastics, particularly in relation to temperature stress. We identified temperature as an underestimated factor that could shape the impacts of plastics, and proposed a roadmap for future research to address their combined effects. This review also highlights the impact of plastic pollution on mussels at multiple levels and emphasises the strong disparities in research effort and the need for more holistic research, notably through the consideration of multiple stressors, with a specific focus on temperature which is likely to become an increasingly relevant forcing factor in an era of global warming. By identifying critical gaps in current knowledge, we advocate for more coordinated interdisciplinary and international collaborations and raise awareness of the need for environmental coherence in the choice and implementation of experimental protocols.

Sustainable Engineering: Utilisation of Biomedical Waste Ash for Untapped Potential in Soil Stabilisation

ABSTRACT The disposal of biomedical waste (BMW) ash presents a growing environmental concern due to its potential to contaminate ecosystems and causes health hazards. This study explores an innovative solution by utilising BMW ash as a sustainable stabiliser to enhance the geotechnical properties of a soft soil, which exhibits low strength and high plasticity characteristics. Through the application of the Taguchi method, the influence of BMW ash concentration and curing period on the soil properties such as compaction, pH, electrical conductivity, and unconfined compressive strength (UCS) were evaluated. The experimental results show that adding BMW ash significantly reduces soil plasticity and increases UCS, achieving a strength gain of more than 180 kPa within 14 days. The optimal combination was determined to be 20% BMW ash with a 14-day curing period. Analysis of variance (ANOVA) revealed that the curing time is the dominant factor, contributing 90.86% to early strength development. Microstructural analysis using SEM and EDX further reveals the formation of ettringite, which promotes early strength gain. This research demonstrates the dual benefits of BMW ash in mitigating environmental waste while improving soil performance, offering a viable solution for both waste management and soil stabilisation challenges.

Synergistic Effects Between Mixed Plastics and Their Impact on Pyrolysis Behavior and Pyrolysis Products.

Pyrolysis is recognized as a promising technology for waste plastics management. Although there have been many studies on pyrolysis of waste plastics, there is still a lack of in-depth research on the mechanism of synergistic effect between mixed plastics and the mechanism of product formation. In this paper, based on the pyrolysis characteristics of Polystyrene, Polyethylene, and mixed plastics (Polystyrene/Polyethylene), it is demonstrated that a synergistic effect exists in the co-pyrolysis of Polystyrene/Polyethylene and affects the pyrolysis behavior and pyrolysis products. It was found that polystyrene chain segments containing C=C double bonds, generated from the pyrolysis of polystyrene, initiated the pyrolysis of polyethylene during the polystyrene/polyethylene co-pyrolysis, resulting in the termination pyrolysis temperature of the co-pyrolysis being advanced by 19.8 K. Due to the reduction in the termination pyrolysis temperature by 19.8 K, the average activation energy of the co-pyrolysis was reduced by about 14%. Compared with the weighted values of single-component plastics (Polystyrene and Polyethylene), the actual oil production of co-pyrolysis increased by 9.7% to 89.80%. At the same time, the content of low molecular weight Styrene and Toluene in pyrolysis oil increased by 12.3% and 1.65%, respectively. This study provides a useful and comprehensive reference for realizing the closed cycle of "from plastics to plastics".

Comprehensive Analysis of Feasibility by Ascending Mining in Coal Mine

In order to study the feasibility of upward mining in a certain coal mine, the mechanical parameters of the coal rock mass were obtained based on on-site investigation and rock mechanics experiments. A numerical model that conforms to the on-site mining layout was established using numerical simulation methods. The stress, displacement, and plastic zone distribution characteristics of the upper coal rock mass at different positions along the X, Y and Z directions after the initial mining of layered coal were analyzed. The critical thickness for tensile failure of the roof during upward mining was calculated using the thick plate theory. A ground penetrating radar was used on site to conduct three-dimensional detection of the fragmentation characteristics of the overlying roof rock. The results show that after the mining of 5# coal, the stress of the overlying roof surrounding rock in the goaf exhibits a dynamic change process of rising peak falling. As the vertical height from the working face increases, the stress in the center of the goaf and around the working face gradually decreases; the displacement distribution extends outwards from the center of the working face, forming a sinking basin with an upward opening in the direction of inclination and direction of the working face. The maximum displacement value is at the bottom of the basin; there is a tensile stress zone above the working face, and the plastic zone has the largest range at the center of the working face direction and inclination. The plastic zone has not evolved to coal 4# and coal 3#; the maximum critical thickness for tensile failure of the roof is 55.4 m, which is much smaller than the actual thickness of 99.82 m on site, and upward mining can be adopted.

Mechanism Study on the Intrinsic Damage and Microchemical Interactions of Argillaceous Siltstone Under Different Water Temperatures

Argillaceous siltstone is prone to deformation and softening when exposed to water, which poses a great threat to practical engineering. There are significant differences in the degrees of damage to this type of rock caused by solutions with different water temperatures. This study aimed to better understand the effect of temperature on argillaceous siltstone by designing immersion tests at water temperatures of 5, 15, 25, and 35 °C, analyzing the mechanical properties and cation concentration shifts under each condition. A water temperature–force coupled geometric damage model for argillaceous siltstone was developed, incorporating a Weibull distribution function and composite damage factors to derive a statistical damage constitutive model. The findings reveal that, with increasing water temperature, the peak strength and elastic modulus of argillaceous siltstone display a concave trend, initially decreasing and then increasing, while the cation concentration follows a convex trend, first increasing and then decreasing. Between 15 and 25 °C, the stress–strain behavior transitions from a four-phase to a five-phase pattern, with pronounced plasticity. The model’s theoretical curves align closely with experimental data, with the Weibull parameters m and λ effectively capturing the rock’s strength and plastic characteristics. Changes in water temperature notably influence the damage variable D12 in the context of water temperature–peak stress coupling, with D12 initially increasing and then decreasing with higher temperatures. These research results can provide new methods for exploring the paths of soft rock disasters and provide guidance for designing defenses in geotechnical engineering.

Hydrogen interaction with 316L steel obtained by selective laser melting

The investigation is focused on the impact of hydrogen on the physical and mechanical properties of 316L austenitic stainless steel (67.5Fe, 17.7Cr, 10.6Ni, 2.6Mo, 1.2Mn, 0.4Si in wt %) processed by selective laser melting (SLM). The study also determined the kinetic parameters of hydrogen interaction with 316L-SLM steel at temperatures ranging from 300 to 700°C. It has been demonstrated that the plasticity characteristics are highly sensitive to the impact of hydrogen within the temperature range from 20 to 600°C. At 600°C, the maximum degree of hydrogen embrittlement is ≈30%. However, the elongation to failure and reduction of area remain at a sufficiently high level. Reduction in strength characteristics is only observed at 600°C and does not exceed 10%. Prolonged thermal impact and resulting structural changes do not affect the kinetic parameters of hydrogen interaction with 316L-SLM. The hydrogen solubility in SLM-processed 316L steel and 12Cr18Ni10T steel produced by conventional technology is nearly identical.

Flexural Behavior of Concrete Members Reinforced with Carbon-Glass Fiber Composite Plate Based on Mechanical Anchoring

This paper presents the bending performance of reinforced concrete (RC) beams reinforced with carbon-glass fiber composite plates of different sizes under mechanical anchorage. The study consisted of the no-reinforced specimen and three reinforced specimens. The studies use a fourth point test method to evaluate the reinforcement effect of the mechanical anchoring carbon-glass fiber composite plate. The test was conducted by measuring the stress and strain of the carbon-glass fiber composite plates between expansion bolts, obtaining the stress distribution characteristics of the carbon-glass fiber composite plates under different load levels, and analyzing the change rule of stress in the plate. Analyze the plastic characteristics of the compression failure and the change of the ductility of the test members, and study the effect of mechanically anchored carbon-glass fiber composite plates reinforced concrete samples on the ductility of the original samples. The results of load-deflection and load-strain analyses show that carbon-glass fiber composite plate reinforcement is more effective. The test results show that the bolted anchorage carbon-glass fiber composite plates can improve the stiffness of the reinforced specimen and inhibit the development rate of concrete cracks in the tensile zone, which reflects the superiority of the mechanical bolted anchorage reinforcement form. The ultimate bending resistance of the mechanically anchored carbon-glass fiber composite plate is significantly improved. With the reasonable increase of the carbon-glass fiber composite plate, the flexural performance of the specimen beam was gradually enhanced. The computational analysis model of the bending reinforcement specimen was established, and the damage morphology of the member was analyzed. The researchers have proposed a theoretical model for calculating the positive section capacity of mechanically reinforced concrete members, and the test results are in good agreement with the theoretical calculation results of the bending capacity proposed in this paper.

Вплив структурних факторів на характеристику пластичності

The main theoretical standson the plasticity characteristic, which is determined by the proportion of plastic deformation in the total defo stands rmation and characterizes the ability of the material to undergo plastic deformation, were developed by Profes-sor Yu. V. Milman. This article is devoted to the experimental verification of theoretical statements about the influence of structural factors on the plasticity characteristic, which can be determined from measurements of hardness (H) and during standard mechanical tests (*). The study was performed on materials with different levels of plasticity (ARMCO–Fe, aluminum alloys AMg5, 7075 and monocrystalline silicon). ARMCO-Fe and aluminum alloy 7075 have different plasticity, but in the investigated range of grain change values (ARMCO–Fe d = 20—550 μm, aluminum alloy 7075 d = = 4—60 μm), the dependence of the plasticity characteristic on d is linear. ARMCO-Fe and aluminum alloy 7075 have different plasticity, but within the investigated range of grain sizes (ARMCO-Fe: d = 20—550 µm, aluminum alloy 7075: d = 4—50 µm), the change in plasticity characteristics in regard to grain size has linear dependences. The resulting dependences of the plasticity characteristic H and * on structural factors showed that a decrease in the grain size and an increase in the density of dislocations, which increase the yield strength of the material, lead to a decrease in the plasticity characteristic. The comparison of experimental data with theoretical ideas about the influence of structural factors on the plasticity characteristic showed a satisfactory match between the theory and the experiment (which will impact to the further development of the theory of the dependence of plasticity on other structural and external factors). Keywords: mechanical properties, plasticity, structure, dislocation density.

Проблемы прочности, хладостойкости и безопасности объектов в зонах Арктики, Севера и Сибири

It has been demonstrated that the operation of industrial facilities in the Arctic zone and areas of Siberia and the North is associated with the increased hazard of the transition of their bearing elements from ductile to quasi-brittle and brittle states. In order to substantiate the safety and cold resistance in accordance with the up-to-date requirements of a risk-oriented approach in the conditions considered, a comprehensive deterministic and probabilistic identification of traditional strength margins considering the variability of standard properties of the material depending on temperature and margins for critical temperatures and critical stresses in ductile, quasi-brittle and brittle states has been proposed. At the same time, together with the assessment of probabilities of the occurrence of hazardous brittle fractures, it is required to determine the damages caused by them to implement the risk assessment of the occurrence of hazardous fractures. Notably, the further development and improvement of interconnected methods of justification of strength, lifetime, and safety in accordance with risk parameters will gain increasing importance. As a basis for such an analysis, it is proposed to use the normal law of probabilityof distribution of probabilities of low-temperature collapses of bridges, viaducts, power lines, and farms is proposed to be used as the initial for such an analysis. The distributions of times of fracture occurrences from the beginning of operation and fracture are nonlinear. The characteristics of strength and plasticity of structures are exponential depending on temperatures. For quantitative assessment of operability, two basic margins for critical stresses and critical temperatures are proposed to be used.

The Effect of Dicarboxylic Acid Structure on the Plasticizing Ability of Its Ester.

Polyvinyl chloride (PVC) belongs to the most widely used group of thermoplastics. Most of the market for PVC products belongs to plasticized compositions. Plasticizers are the most demanded additives in the polymer industry. Environmental problems and the identified toxicity of the plasticizer di(2-ethylhexyl) phthalate (DEHP) stimulate the restriction of its use and contribute to the development of alternative plasticizers. As a possible replacement for phthalates, esters of dicarboxylic acids are known to provide reduced toxicity and high frost resistance to the resulting compositions. In this regard, esters of dicarboxylic acids and ethoxylated alcohols were obtained and their compatibility with polyvinyl chloride was investigated. The plasticizing effect of the esters obtained was evaluated. The thermomechanical characteristics of PVC compositions containing the developed plasticizers were studied, the glass transition temperature was determined, and the areas of the glassy and highly elastic state of the plastics were identified. It was shown that the chemical structure of dicarboxylate used as a plasticizer determines the important technological and operational characteristics of the PVC plastics obtained. Dibutoxyethyl sebacate (DBES) has the best plasticizing effect among the synthesized esters. The expansion of the highly elastic state area for PVC samples containing this ester exceeded the industrial plasticizers DEHP and di(2-ethylhexyl) adipate (DOA). The indicators of the critical temperature of dissolution of PVC in the esters under study suggest ensuring their low migration from PVC plastics.

CMTM7 shapes the chronic inflammatory and immunosuppressive tumor microenvironment in hepatocellular carcinoma as an M2 macrophage biomarker

Transmembrane domain-containing 7 (CMTM7) is a protein located at the plasma membrane. It plays a role in regulating the development and immune microenvironment of tumor cells. However, the impact of CMTM7 on hepatocellular carcinoma (HCC) is not well understood. To better understand the role of CMTM7 in HCC, the correlations of CMTM7 with clinical characteristics, patient prognosis, chronic inflammation, and immune cell infiltration were analyzed using tissue microarray slides, sequencing datasets and various analysis tools (Web). The bulk sequencing analysis indicated that elevated expression of CMTM7 appears to promote chronic inflammation, immunosuppression, M2 macrophage infiltration, a diminished response to cancer immunotherapy, and an unfavorable clinical prognosis in patients with hepatocellular carcinoma (HCC). Further investigation through single-cell RNA sequencing and multiple fluorescence staining demonstrated that CMTM7 serves as a molecular marker for M2 macrophages and is associated with T cell exhaustion as well as highly plastic stem-like characteristics. We propose that CMTM7 may represent a novel immune checkpoint for HCC patients experiencing suboptimal therapeutic outcomes. Utilizing the Connectivity Map and AutoDock Vina, we predicted two potential compounds targeting CMTM7—fasudil and arachidonyltrifluoromethane—as promising therapeutic candidates. Collectively, these findings suggest that CMTM7-positive macrophages play significant roles in establishing an immunosuppressive tumor microenvironment while promoting highly plastic and stem-like traits in HCC cells, ultimately contributing to poor prognostic outcomes.

Influence of Rocking Shallow Foundation Parameters and Analysis of Seismic Response Characteristics

Rocking shallow foundations interrupt the seismic transmission path from the base of the structure and possess advantages, such as effective seismic isolation, self-resetting capabilities post-earthquake, and low costs. A numerical model of the rocking shallow foundation was developed in OpenSees (version: Opensees 3.5.0) based on field test data using numerical simulation. The effect of different parameters (column height, foundation sizes, top mass, and soil softness and stiffness) on the seismic response characteristics of rocking shallow foundations is investigated, and the seismic response characteristics of rocking shallow foundations are analyzed under the action of sinusoidal waves of different frequencies and various seismic wave types. The results of the study show that, as the height of the column increases, the bending moment decreases and settlement decreases; as the size of the foundation increases, the bending moment increases and settlement increases; as the mass of the top increases, the bending moment increases and settlement increases; and as the soil becomes softer, the bending moment decreases, and settlement increases. Inputting a sine wave that matches the structure’s natural oscillation frequency may induce resonance. This phenomenon can significantly amplify the structure’s vibrations; thus, it is essential to avoid external excitation frequencies that coincide with the foundation’s natural oscillation frequency. Under seismic loading, the rocking shallow foundation can mitigate the bending moment in the superstructure. When the displacement ratio remains within −0.5 to 0.5 percent, the foundation settlement is minimal. However, when the absolute displacement ratio exceeds 0.5 percent, the soil exhibits plastic deformation characteristics, resulting in increased foundation settlement. This study is an important contribution to the improvement of seismic performance of buildings and an important reference for improving seismic design standards and practices for buildings in earthquake-prone areas. In the future, the seismic response characteristics of rocking shallow foundations under bidirectional seismic action will be investigated.

Porosity and cement controlling the response of artificially cemented tailings under hydrostatic loading to high pressures

Cemented tailings find various applications in mining, such as open-pit and underground backfill, dam decommissioning and filtered tailings stacking. This research investigates the compression behaviour of iron ore tailings (IOT) mixed with distinct amounts of Portland cement and compacted in different conditions through isotropic compression, pulse velocity, and unconfined compression tests. The results show the adequacy of the porosity/cement index (η/Civ) in predicting elastic and plastic characteristics of compacted filtered IOT - Portland cement blends, an original correlation that has not been reported by previous work. This index is useful in selecting the cement content and target density for essential parameters required to design cemented IOT stacks. Besides, both cement addition and compaction have promoted the tailings isotropisation (conversion of an anisotropic system to an isotropic one). The evolution of the Post-Yield Compression Line (PYCL) with cementation is shown. Finally, it is demonstrated that distinct initial (after compaction) porosities of uncemented specimens reach a unique PYCL after isotropic pressures above 100 MPa, and cemented specimens do not reach a unique PYCL even at 120 MPa of isotropic pressures. The results underscore the requirement of rigorous compaction control in the field and offer a methodology for the dosage and technological control of artificially cemented tailings.

Investigation on the cyclic buckling and plastic overstrength characteristics of steel shear links utilizing corrugated panels

This paper established and validated the finite element model (FEM) for novel steel shear links utilizing corrugated panels (CSSL), analyzed the stress and strain distributions of CSSL, and summarized the buckling characteristics and determination criteria for CSSL. Utilizing the FEM, the influence of CSSL configuration parameters on its buckling deformation capacity and plastic overstrength characteristics were analyzed. The analysis results indicated that: the decrease in the corrugated panel's sub-panel slenderness a/tw could significantly improve the buckling deformation capacity of CSSL, but had little influence on pre-buckling plastic overstrength characteristics; the decrease in sub-panel aspect ratio h/a and web aspect ratio e/h, as well as the increase in web corrugation angle θ was beneficial for the buckling deformation capacity of CSSL, but might decrease the plastic overstrength characteristics; the decrease in the equivalent links length coefficient eVp/Mp and the increase in structural steel strain-hardening value α had a slight influence on the buckling deformation capacity, but could significantly improve the plastic overstrength characteristics. Based on the analysis result, a theoretical prediction approach for the buckling deformation capacity and plastic overstrength characteristics was proposed, and the load-deformation skeleton curve model was also established, which was validated to exhibit good accuracy with compassion to experimental and finite element analysis results.

Enhancement of Synaptic Behavior in Organic Electrochemical Transistors via the Introduction of Layer‐by‐Layer Grown Metal‐Organic Framework

AbstractOrganic electrochemical transistors (OECTs) are promising for neuromorphic architectures as they can generate multiple electrical states through the control of ion transport. However, conventional OECTs face limitations in mimicking a fully functional biological synapse due to their inability to achieve long‐term plasticity. In this study, a metal‐organic framework (MOF)‐enhanced OECT (MOECT) is fabricated by introducing MOF into the ion‐organic semiconductor (OSC) layer. MOFs are synthesized using the layer‐by‐layer (LBL) method, and additional cross‐linked OSC is introduced to prevent damage to the semiconductor layers during synthesis. The synthesized MOF layers hinder the rediffusion of ions in OECT, allowing ions to remain in the OSC for an extended period. In this study, the MOECT showed a change in current depending on the doping level, recording a current state 4.4 × 107 times higher than that of pristine OECT. Ultimately, the developed MOECTs are applied as synaptic transistors. MOECTs show 14% higher excitatory postsynaptic current (EPSC) after 130 s compared to pristine OECT, thereby strengthening the long‐term plasticity characteristics of neuromorphic devices. This method enhances the performance of synaptic transistors by introducing MOF, offering various possibilities through the selection of different MOF structures and ions, indicating it is a methodological approach with high potential.
