FUNDAMENTAL RESEARCH ON GALLIUM-BASED LIQUID METAL FLEXIBLE ROBOTS
type: item
description: This research focuses on the fundamental study of gallium-based liquid metal flexible robots. First, the composition and ratio of the alloy were determined, and a gallium-indium alloy liquid metal suitable for flexible robots was successfully fabricated. The research conducts experimental studies on the morphological changes and movement of liquid metal under electric field control. Quantitative conclusions were drawn, revealing that the deformation speed is proportional to the applied voltage, with a stable deformation region around 40 seconds. Once the electric field is removed, the deformation is reversible, and the recovery speed is consistent. Lastly, qualitative research examined the effects of conductive and non-conductive substrates on liquid metal deformation and movement, considering factors such as charge polarity and the surface oxide film. On non-conductive substrates, the deformation is reversible and moves towards the positive electrode, whereas on conductive substrates, the deformation is irreversible and moves towards the negative electrode.

RESEARCH PROGRESS ON SOLID-STATE ELECTROLYTES AND THEIR MANUFACTURING PROCESSES
type: item
description: With the increasing demand for high energy density and enhanced safety in energy storage systems, conventional lithium-ion batteries employing liquid electrolytes have gradually exhibited intrinsic limitations in both safety and performance improvement. All-solid-state batteries, which replace flammable liquid electrolytes with solid electrolytes, are widely regarded as one of the most promising candidates for next-generation high-safety energy storage technologies. However, solid electrolytes still face considerable challenges in terms of material properties, interfacial stability, and large-scale manufacturing, which significantly hinder their practical application. This thesis presents a systematic review of solid electrolytes and their production processes. Firstly, the current research status of major solid electrolyte material systems, including oxide-based, sulfide-based, polymer-based, and composite solid electrolytes, is comprehensively summarized, with particular emphasis on their ionic conduction mechanisms, chemical stability, and engineering applicability. Subsequently, the progress in key fabrication techniques of solid electrolytes is reviewed, focusing on the influence of processing conditions on microstructure and electrochemical performance. Furthermore, the critical interfacial issues in all-solid-state batteries are discussed, and recent advances in interfacial engineering strategies are analyzed. Finally, combined with the current status of industrialization, the technical routes and future development trends of all-solid-state batteries are evaluated. Through an integrated analysis of material systems, manufacturing processes, interfacial engineering, and industrialization pathways, this work aims to provide a systematic reference for research on solid electrolytes and all-solid-state batteries, as well as insights into their further engineering implementation.

type: item
description: In order to reduce the impact of intensive noise on personnel comfort in multi-functional exhibition halls, based on the micro-perforation theory, this paper systematically analyzes the sound insulation and sound absorption properties of ultra-microporous honeycomb aluminum panels. By establishing an acoustic finite element model, simulation technology was used to explore the sound insulation and sound absorption coefficient of ultra-microporous honeycomb aluminum panels in the range of 100Hz to 5000Hz. At the same time, the sound insulation amount and sound absorption coefficient were experimentally measured by combining the reverberation chamber method and the standing wave tube method. The results show that the simulation results of ultra-microporous aluminum honeycomb panels are highly consistent with the experimental data. The weighted sound insulation is 27.0dB (experimental value 26.8dB), and the sound absorption coefficient NRC reaches 0.63, which is significantly better than ordinary aluminum honeycomb panels. Research shows that ultra-microporous honeycomb aluminum panels have good noise reduction effects, help improve the acoustic environment in large spaces, and improve personnel comfort.

type: item
description: In order to create a healthy and comfortable indoor environment, based on the sandwich lightweight partition structure, this article systematically analyzes the impact of factors such as the type of filling material in the partition wall cavity, the thickness of the filling material, the number and quality of panel layers on its sound insulation performance. Through experimental tests, the reverberation chamber method was used to measure the sound insulation amount and the standing wave tube method was used to measure the sound absorption coefficient, and the effects of different filling materials and structural parameters on the sound insulation effect were compared. The results show that filling glass wool or rock wool materials significantly improves the sound insulation of sandwich partition walls, and increasing the thickness of the filling material and the number of panel layers further optimizes the sound insulation performance. The research results provide a theoretical basis for the design of indoor partition walls and help improve indoor acoustic comfort.

EVALUATION OF THE CORROSION INHIBITION PROPERTIES OF ETHANOLIC EXTRACT FROM ACACIA NILOTICA POD ON MILD STEEL IN 0.1 M SULFURIC ACID: AN EXPERIMENTAL STUDY UTILIZING FTIR AND SEM TECHNIQUES
type: item
description: The ethanol extract of Acacia nilotica pod (ANP) was investigated for its corrosion inhibition potential on mild steel immersed in 0.1M H 2 SO 4 solutions containing ANP concentrations ranging from 0.1 to 0.5 g/L. The study employed weight loss measurements, Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM) to evaluate the extract’s performance. Weight loss experiments demonstrated that the inhibition efficiency was influenced by both the concentration of ANP and the exposure duration of the mild steel in the acidic medium. The highest inhibition efficiency recorded was 87.57%. Surface morphology analysis using SEM revealed significant differences between the steel samples exposed to H 2 SO 4 with and without the extract, indicating the protective role of ANP. FTIR spectroscopy further confirmed the adsorption of the extract onto the mild steel surface, with functional groups such as C-O and N=O playing a critical role in the adsorption process. These findings highlight the potential of ANP as an effective corrosion inhibitor for mild steel in acidic environments.

FABRICATION OF POLYPROPYLENE NANOCOMPOSITE FOR SUPERLATIVE REFRIGERATED VEHICLE PANELS
type: item
description: Refrigerated foods vehicle by road is made up of three-layered materials insulated panel that has insulation foam, situated intermediate to two high thermal conductive aluminum metal sheets. Usually, a loss of insulation value in a refrigerated vehicle every year is a result of the increase in heat absorption and heat transfer of the metal sheets, which affect the cooling temperature in a refrigerated vehicle panel chamber. The study aims at proposing the fabrication of polypropylene nanocomposite for superlative refrigerated vehicle panels, by producing and testing low-thermal conductive polymer-based composite materials with nanoclay (NC) particles for use in superlative refrigerated vehicle panels. The melt blending compounding method involved the pre-treatment of materials, preparation of composite samples, and the characterization of the new samples for their: mechanical, morphology, and thermal properties. The result of the study shows that melt blending influenced the composites’ mechanical, morphology, and thermal properties. Meanwhile, the processing route exhibited an intercalated morphology structure, which enhanced the composites’ strength, stiffness, and thermal conductivity. Finally, the sample with 3% nanoclay by weight had the optimum property and could be, recommended for refrigerated vehicle panel insulation.

description: The advent of Chinese-style modernization has precipitated unprecedented transformations in the medical insurance system, necessitating a paradigm shift in medical insurance education. Through a comprehensive mixed-methods approach combining systematic literature review, empirical investigation, and multi-site case studies, this research examines the evolving landscape of medical insurance education and develops an innovative reform framework. The findings indicate three critical dimensions requiring immediate attention: First, the digital transformation gap, where current professionals lack advanced capabilities in data analytics, artificial intelligence, and blockchain applications; Second, the interdisciplinary knowledge gap, highlighting the need for broader integration of public health, clinical management, and economic analysis; Third, the practical operation gap, emphasizing the importance of real-world policy implementation and system operation management experience. To address these challenges, the study proposes a comprehensive curriculum reform framework that encompasses three integrated modules: core courses focusing on fundamental theories and digital applications, specialized elective courses addressing emerging technological and policy developments, and practical courses emphasizing hands-on experience through industry partnerships. The research further delineates specific implementation strategies across three key areas: (1) faculty team building through strategic recruitment and comprehensive training programs, (2) teaching resource optimization incorporating advanced digital platforms and case-based learning materials, and (3) evaluation mechanism reform featuring multi-dimensional assessment criteria. The study's findings suggest that successful curriculum reform requires the synchronization of theoretical knowledge modernization, practical skill enhancement, and interdisciplinary integration, supported by robust industry-education partnerships an…

type: item
description: Covalent organic frameworks, characterized by their stable porous layered structures, are promising candidates for supercapacitor electrode materials. In this study, a benzimidazole-based COF material (DAB-BTC-COF) was synthesized via thermal reaction using 3,3',4,4'-biphenyltetramine and 1,3,5-benzenetricarboxylic acid as monomers. The structural integrity of the synthesized material was confirmed through X-ray diffraction and Fourier-transform infrared spectroscopy. Electrochemical evaluations revealed that DAB-BTC-COF exhibits electric double-layer capacitive behavior with excellent reversibility in acidic electrolytes. Electrochemical impedance spectroscopy indicated negligible charge transfer resistance and high conductivity, while galvanostatic charge-discharge tests demonstrated high-rate capability, superior power density, and robust cycling stability.

SYNTHESIS OF TWO-DIMENSIONAL ORGANIC FRAME MATERIALS: CLASSIFICATION, APPLICATIONS, PROBLEMS AND MODIFICATION APPROACHES
type: item
description: Organic framework materials, including MOFs and HOFs, are widely used in multiple fields. MOFs are formed by the self-assembly of inorganic metal centers and organic ligands, and there are various types such as IRMOFs and ZIFs. Post-synthetic modification (PSM) can expand their functional groups. HOFs connect building units through hydrogen bonds. They have advantages like mild preparation conditions and good solution-processing performance, but the characteristics of hydrogen bonds also limit their development. Two-dimensional MOFs combine the advantages of MOFs and ultrathin two-dimensional materials. There are two preparation strategies: "top-down" and "bottom - up". The "top-down" method, including physical and chemical exfoliation methods, can exfoliate bulk MOFs into nanosheets, but there are problems such as uneven product thickness and low yield. The "bottom-up" methods, such as the solvothermal method, interface synthesis method, and auxiliary synthesis method, can prepare nanosheets with uniform thickness, but each has its pros and cons. Overall, organic framework materials have broad prospects, but they still face challenges in synthesis, performance optimization, etc., and further research and improvement are needed.

ADAPTIVE MOLECULAR GRAPH ABSTRACTION VIA REINFORCEMENT LEARNING ACROSS GEOMETRIC SCALES
type: item
description: Molecular graph representation learning has emerged as a fundamental challenge in computational chemistry and drug discovery, where the ability to capture multi-scale structural information from atomic to molecular levels is crucial for accurate property prediction and molecular design. Traditional graph neural network approaches typically operate at a single resolution, failing to capture the hierarchical nature of molecular structure that spans multiple geometric scales from local atomic environments to global molecular topology. This paper presents a novel framework that employs Adaptive Molecular Graph Abstraction (AMGA) through reinforcement learning to dynamically learn optimal abstraction strategies across different geometric scales. The proposed framework combines hierarchical graph pooling mechanisms with reinforcement learning agents that adaptively select abstraction levels and pooling strategies based on molecular characteristics and task requirements. Our approach employs differentiable clustering algorithms that learn to group atoms into chemically meaningful motifs, progressing through multiple pooling levels to create increasingly abstract molecular representations. The reinforcement learning component formulates abstraction strategy selection as a sequential decision-making problem, enabling dynamic adaptation to different molecular families and property types. Experimental evaluation demonstrates superior reconstruction accuracy compared to existing approaches, with our method maintaining over 85% accuracy across all molecule sizes while baseline methods like CG-VAE deteriorate significantly for larger molecules. The adaptive abstraction mechanism enables automatic discovery of optimal representation granularities for different chemical contexts, providing interpretable insights into structure-property relationships while maintaining computational efficiency suitable for large-scale molecular screening applications.

type: item
description: Prepare ordinary concrete (NC) and vitrified microbead insulation concrete (GHB/NC), and study the deterioration process of changes in apparent phenomena, quality, loss of compressive strength and other properties after heating from normal temperature to 1000°C, and discuss ultrasonic non-destructive testing at the same time The method is used to evaluate the universality of the performance of concrete after high temperatures, comparatively analyze the relationship between relative wave speed, damage degree, heating temperature, and compressive strength loss rate, and use SEM to observe the microstructural changes of specimens after different high temperatures. The results show that the use of relative wave speed and damage degree to evaluate the performance of concrete after high temperature has good correlation, and the regression formula has a high fitting degree; as the temperature increases, the internal damage of NC and GHB/NC concrete gradually intensifies, and the cement gelation decomposes due to heat and moisture Dissipation, etc. produce gaps, cracks and interconnections on the surface and inside of the specimen, and the bonding force at the interface between vitrified microspheres, coarse aggregate and cement stone gradually weakens or even loses, causing the macroscopic mechanical properties to deteriorate and the compressive strength loss rate to increase. After heating to 800℃, the strength loss of NC is 72.3%, the strength loss of GHB/NC is 74.6%, and the load-bearing capacity is basically lost at 1000℃.

type: item
description: Using the improved Tanaka-Mura model, the equivalent conversion relationship between complex fatigue load and tension-compression fatigue load is determined, and the influence law of residual compressive stress is given. The fatigue life and crack origin location of samples were systematically analyzed numerically. The results show that: the fatigue nucleation life and position of the notched specimen are related to the thickness of the strengthening layer, the hardness ratio of the surface to the matrix and the residual stress; the change of the thickness of the strengthening layer will change the crack nucleation position; there is a critical thickness, when the thickness of the strengthening layer is less than the critical thickness, the crack nucleates at the interface between the strengthened layer and the matrix, otherwise, it nucleates at the strengthened subsurface or surface; the increase in the hardness ratio of the surface to the matrix will lead to an increase in the critical thickness; the residual compressive stress has little effect on the fatigue initiation life, while the residual Tensile stress significantly reduces the fatigue initiation life.

description: Through a two-step organic reaction, a reactive difluorosulfone monomer with a 3,5-diphenylbenzene side group structure—3,3'-bis(3,5-diphenylbenzene) was designed and synthesized. -4,4'-Difluorodiphenylsulfone. Using this monomer, 4,4'-difluorodiphenylsulfone and 4,4'-dihydroxybenzophenone as starting materials, a series of Sulfonated polyarylsulfone proton exchange membrane (TS-PAS-xx). The structure of the prepared polymer was characterized and analyzed by infrared spectroscopy and hydrogen nuclear magnetic resonance spectroscopy, respectively. The results show that the prepared proton exchange membrane exhibits moderate water absorption and low swelling rate. At 80 ℃, the swelling rate of the membrane does not exceed 15.7%. Atomic force microscopy tests showed that these proton exchange membranes formed an obvious "hydrophilic-hydrophobic" phase separation structure, which was conducive to the improvement of proton conductivity. The proton conductivity of TS-PAS-34 membrane reached 182 mS / cm, comparable to Nafion112, superior to other reported conductivities of some polyarylsulfone proton exchange membranes with the same ion exchange capacity (IEC). The film also has good thermal properties, mechanical properties and excellent stability against chemical oxidation.

MOISTURE ABSORPTION BEHAVIOR OF AEROSPACE CARBON FIBER REINFORCED RESIN MATRIX COMPOSITE STIFFENED PANELS
type: item
description: In order to study the moisture absorption characteristics of carbon fiber reinforced resin matrix composite reinforced wall panels in hot and humid environments, moisture absorption experiments were carried out at 70 ℃ / 85% relative humidity. Combined with the experimental data, a composite reinforced wall panel was proposed. The stage moisture absorption model of this type of structure, and the finite element simulation of the moisture absorption behavior of this type of structure is carried out. The results show that the composite reinforced wall panel complies with Fick's law of moisture absorption in the early stage of moisture absorption, and there is obvious staged moisture absorption phenomenon in the late stage of moisture absorption; the proposed staged moisture absorption model has high analysis accuracy, and the moisture absorption curve of the staged moisture absorption model is consistent with the finite element simulation results Keep consistent, and the calculation error is within 5%. The results of moisture concentration distribution reveal the stage moisture absorption mechanism of composite reinforced wall panels, and the difference in the moisture absorption equilibrium rate of the structure at different thicknesses is the main reason for the stage moisture absorption phenomenon.
