Flash Joule heating(FJH),as a high-efficiency and low-energy consumption technology for advanced materials synthesis,has shown significant potential in the synthesis of graphene and other functional carbon materials.Based on the Joule effect,the solid carbon sources can be rapidly heated to ultra-high temperatures(>3000 K)through instantaneous high-energy current pulses during FJH,thus driving the rapid rearrangement and graphitization of carbon atoms.This technology demonstrates numerous advantages,such as solvent-and catalyst-free features,high energy conversion efficiency,and a short process cycle.In this review,we have systematically summarized the technology principle and equipment design for FJH,as well as its raw materials selection and pretreatment strategies.The research progress in the FJH synthesis of flash graphene,carbon nanotubes,graphene fibers,and anode hard carbon,as well as its by-products,is also presented.FJH can precisely optimize the microstructures of carbon materials(e.g.,interlayer spacing of turbostratic graphene,defect concentration,and heteroatom doping)by regulating its operation parameters like flash voltage and flash time,thereby enhancing their performances in various applications,such as composite reinforcement,metal-ion battery electrodes,supercapacitors,and electrocatalysts.However,this technology is still challenged by low process yield,macroscopic material uniformity,and green power supply system construction.More research efforts are also required to promote the transition of FJH from laboratory to industrial-scale applications,thus providing innovative solutions for advanced carbon materials manufacturing and waste management toward carbon neutrality. 展开更多

Ultrasensitive and simultaneous quantitative detection of Listeria monocytogenes(L.monocytogenes)that can survive in vacuum packaging and frozen food is critical to public health.Herein,teamed boronate affinity(TBA)magnetically functionalized materials combined with biomass fluorescent probe for L.monocytogenes detection in a sandwich-like strategy was established.Firstly,we prepared new TBA magnetically functionalized materials by reducing the pKa value of phenylboronic acid through the TBA strategy in the form of self-assembled intermolecular B-N coordination bonding.To our knowledge,this is the first study where TBA magnetically functionalized materials were utilized for the identification and capture of bacteria,with a high capture efficiency of over 90.8%in spiked lettuce samples for L.monocytogenes(within 35 min),showing superior capture ability.Then,Anti-L.monocytogenes monoclonal antibody was labeled in biomass-derived fluorescent probe with the help of biotin-streptavidin system to achieve specific and sensitive detection of L.monocytogenes.The sandwich-like strategy shows high sensitivity of designed fluorescence sensing platform for L.monocytogenes with a wide linear range(2.2×10^(1)-2.2×10^(6)CFU/mL),a low limit of detection(2.2×10^(1)CFU/mL),and a satisfactory recovery rate(85.19%-106.69%)spiked lettuce sample.Notably,the method was low-cost,general and had strong application prospects in the field of food safety. 展开更多

The urgent demand for renewable energy solutions,propelled by the global energy crisis and environmental concerns,has spurred the creation of innovative materials for solar thermal storage.Photothermal phase change materials(PTPCMs)represent a novel type of composite phase change material(PCM)aimed at improving thermal storage efficiency by incorporating photothermal materials into traditional PCMs and encapsulating them within porous structures.Various porous encapsulation materials have been studied,including porous carbon,expanded graphite,and ceramics,but issues like brittleness hinder their practical use.To overcome these limitations,flexible PTPCMs using organic porous polymers—like foams,hydrogels,and porous wood—have emerged,offering high porosity and lightweight characteristics.This review examines recent advancements in the preparation of PTPCMs based on porous polymer supports through techniques like impregnation and in situ polymerization,assessing the impact of different porous polymer materials on PCM performance and clarifying the mechanisms of photothermal conversion and heat storage.Subsequently,the most recent advancements in the applications of porous polymer-based PTPCMs are systematically summarized,and future research challenges and possible solutions are discussed.This review aims to foster awareness about the potential of PTPCMs in promoting environmentally friendly energy practices and catalyzing further research in this promising field. 展开更多

Cellulosic materials are attracting increasing research interest because of their abundance,biocompatibility,and biodegradability,making them suitable in multiple industrial and medical applications.Functionalization of cellulose is usually required to improve or expand its properties to meet the requirements of different applications.Cellulose-binding domains(CBDs)found in various proteins have been shown to be powerful tools in the functionalization of cellulose materials.In this review,we firstly introduce the structural characteristics of commonly used CBDs belonging to carbohydrate-binding module families 1,2 and 3.Then,we summarize four main kinds of methodologies for employing CBDs to modify cellulosic materials(i.e.,CBD only,genetic fusion,non-covalent linkage and covalent linkage).Via different approaches,CBDs have been used to improve the material properties of cellulose,immobilize enzymes for biocatalysis,and design various detection tools.To achieve industrial applications,researches for lowering the production cost of CBDs,improving their performance(e.g.,stability),and expanding their application scenarios are still in need. 展开更多

SS316L alloy coupled with Inconel625 alloy were combined with Ti6Al4V or Inconel718 alloy through wire arc additive manufacturing technique to manufacture functionally graded materials(FGMs).Two FGMs,namely 60%SS316L+20%Inconel625+20%Ti6Al4V composite and 60%SS316L+20%Inconel625+20%Inconel718 composite,were prepared.The tensile strength,elongation,yield strength,hardness,cross section area of the parent material,and composition were analysed.Results illustrate that the 60%SS316L+20%Inconel625+20%Inconel718 composite has better mechanical properties than 60%SS316L+20%Inconel625+20%Ti6Al4V composite,and the comprehensive properties of 60%SS316L+20%Inconel 625+20%Ti6Al4V composite are better than those of the parent material SS316L.Hence,the composite of 60%SS316L+20%Inconel625+20%Inconel718 is optimal.Due to its high strength,the 60%SS316L+20%Inconel625+20%Inconel718 composite has great application potential in the field of high pressure pneumatic tool and defence tool. 展开更多

Fe-Mo functionally graded materials(FGMs)with different composition-change rates from 100%304 stainless steel to 100%Mo along the composition gradient direction were prepared by electron beam-directed energy deposition(EB-DED)technique,including three samples with composition mutation of 100%,composition change rate of 10%and 30%.Results show that the composition-change rate significantly affects the microstructure and mechanical properties of the samples.In the sample with abrupt change of composition,the sharp shift in composition between 304 stainless steel and Mo leads to a great difference in the microstructure and hardness near the interface between the two materials.With the increase in the number of gradient layers,the composition changes continuously along the direction of deposition height,and the microstructure morphology shows a smooth transition from 304 stainless steel to Mo,which is gradually transformed from columnar crystal to dendritic crystal.Elements Fe,Mo,and other major elements transform linearly along the gradient direction,with sufficient interlayer diffusion between the deposited layers,leading to good metallurgical bonding.The smaller the change in composition gradient,the greater the microhardness value along the deposition direction.When the composition gradient is 10%,the gradient layer exhibits higher hardness(940 HV)and excellent resistance to surface abrasion,and the overall compressive properties of the samples are better,with the compressive fracture stress in the top region reaching 750.05±14 MPa. 展开更多

Polyvinyl chloride(PVC)poses persistent environmental and recycling challenges due to its high chlorine content,complex additives,and structural resistance to degradation.Recent research has shifted focus from traditional disposal methods toward chemically informed strategies that valorize PVC within the framework of a circular economy.This review systematically summarizes three emerging pathways for PVC transformation.The first involves catalytic deconstruction into small molecules such as chlorinated olefins,hydrocarbons,and oxygenates through thermal,photocatalytic,and electro-assisted processes.The second explores backbone-preserving reconstruction into functional materials,including porous carbons,membranes,ion-conducting films,and vitrimer-type polymers by leveraging selective dechlorination and structural reprogramming.The third addresses the co-processing of PVC with mixed plastic wastes through synergistic catalytic systems that tolerate chlorine-rich streams and promote selective transformation.Across all pathways,emphasis is placed on structure-property correlations,chlorine management,additive compatibility,and downstream utility.Summary tables and schematic diagrams are included to compare system efficiencies,product selectivities,and application scopes.By integrating mechanistic understanding with materials innovation,this review highlights how PVC can be reimagined as a tunable molecular platform rather than a persistent pollutant. 展开更多

This study focuses on permanent surface dislocations caused by a strike-slip fault in an alluvial valley.A twodimensional mathematical model is utilized,considering the valley to have a half-cylindrical shape.The valley medium is assumed to be isotropic,linear elastic and nonhomogeneous,such that the shear modulus of the valley has spatial dependency.The valley is surrounded by an isotropic,linear elastic and homogeneous half-space.A strike-slip fault is located at the intersection between the valley and the half-space.The problem is solved analytically by using finite Fourier transform.Displacement functions are obtained in closed-form,in terms of power series and hypergeometric function series.Unknown coefficients of these series are determined from the boundary conditions,leading to an analytical exact solution.Numerical results indicate that the nonhomogeneity of the alluvial valley material has a limited impact on permanent surface dislocations unless there is a significant variation in the material properties within the functionally graded zone.In many cases,approximating the nonhomogeneous alluvial valley as a homogeneous medium is suitable. 展开更多

The accurate mechanical analysis of thick-walled pressure vessel structures composed of advanced materials,such as hyperelastic and functionally graded materials(FGMs),is critical for ensuring their safety and optimizing their design.However,conventional numerical methods can face challenges with the non-linearities inherent in hyperelasticity and the complex spatial variations in FGMs.This paper presents a novel hybrid numerical approach combining Physics-Informed Neural Networks(PINNs)with Finite Element Method(FEM)derived data for the robust analysis of thick-walled,axisymmetric,heterogeneous,hyperelastic pressure vessels with elliptical geometries.A PINN framework incorporating neo-Hookean constitutive relations is developed in MATLAB.To enhance training efficiency and accuracy,the PINN’s loss function is augmented with displacement data obtained from high-fidelity FEM simulations performed in ANSYS.The methodology is rigorously validated by comparing PINN-predicted displacement and von Mises stress fields against ANSYS benchmarks for various scenarios of FGMconfigurations(with material properties varying according to a power law)subjected to internal and external pressurization.The results demonstrate excellent agreement between the proposed hybrid PINN-FEMapproach and conventional FEMsolutions across all test cases,accurately capturing complex deformation patterns and stress concentrations.This study highlights the potential of data-augmented PINNs as an effective and accurate computational tool for tackling complex solid mechanics problems involving non-linearmaterials and significant heterogeneity,offering a promising avenue for future research in engineering design and analysis. 展开更多

This study explores the dynamic contact response of a viscoelastic functionally graded material(FGM)-coated half-plane under a rigid flat punch subjected to a time-harmonic vertical force.The elastic modulus and mass density of the FGM coating vary exponentially along the thickness direction.The FGM coating and the homogeneous half-plane possess viscoelastic properties,which are described by a linearly hysteretic damping model.By applying the asymptotic method and the Fourier integral transform technique,the contact problem is converted into a Cauchy singular integral equation.The effects of excitation frequency,gradient index,damping factor ratio,and punch width on the vertical impedance and dynamic contact stress are analyzed.The results indicate that adjusting the gradient index of the FGM coating can significantly affect the contact stress and vertical impedance. 展开更多

The effects of the component gradient distribution at interface and the fiber gradient distribution on the strength of cement-based materials were studied. The results show that the flexural strength and compressive strength of the mortar and concrete with interface component and fiber gradient distributions are obviously improved. The strengthes of the fiber gradient distributed mortar and concrete (FGDM/C) are higher than those of fiber homogeneously distributed mortar and concrete (FHDM/C). To obtain the same strength, therefore, a smaller fiber volume content in FGDM/C is needed than that in FHDM/C. The results also show that the component gradient distribution of the concrete can be obtained by means of multi-layer vibrating formation. 展开更多
