The purpose of this study lies in exploring the role of materiality in environmental information disclosures under the securities laws of the United States and China,discussing the differences in the regulatory mechanism,limits of enforcement,and challenges of seeking global harmonization.The paper does a comparative legal analysis of statutory provisions,judicial interpretations,and regulatory frameworks of the U.S.Securities and Exchange Commission(SEC)and the China Securities Regulatory Commission(CSRC).Furthermore,it provides frameworks of global sustainability reporting such as the Task Force on Climate-related Financial Disclosures(TCFD)and the Global Reporting Initiative(GRI).The findings show that U.S.securities law uses a financial materiality standard with respect to what companies must disclose to investors.On the other hand,China’s regulatory approach has a double materiality in considering not only financial impacts but also wider environmental and social factors.Although there are these distinctions,both of these jurisdictions face issues of common obstruction such as ambiguities in materiality determination,inconsistent enforcement,and fear of greenwashing.This paper asserts that the U.S.and China regulatory frameworks need to converge more to promote greater corporate transparency and ESG disclosures.Regulators can even align disclosure practices with internationally recognized standards of work to add confidence for investors,fight off misleading sustainability claims and ensure accountable reporting in pertinent environments.The study concludes that the green challenges of global markets can only be tackled by regulating cooperative actions and using standardized reporting guidelines. 展开更多

New materialism has become one of the most influential theoretical vocabularies for rethinking agency,embodiment,ecology,and the posthuman condition.Yet its major formulations remain largely organized by a Euro-American archive in which matter must be rescued from the long shadow of substance ontology,representationalism,and the passive object.This article proposes a Chinese intervention in that debate by reinterpreting qi(气)as a dynamic and processual form of materiality.Rather than treating qi as a mystical substance,a premodern energy,or a cultural metaphor,the article reconstructs it as a relational,transformative,and self-differentiating mode of material becoming.Through a critical dialogue with Karen Barad[1]’s agential realism[1]and Jane Bennett[2]’s vibrant matter,it argues that qi offers a non-substantialist ontology in which materiality is neither inert stuff nor discrete thinghood but the ongoing modulation of forces,tendencies,intensities,and relational configurations.The article introduces the concept of“processual materiality”to describe this ontological logic.Processual materiality names a mode of matter that is real without being static,efficacious without being anthropomorphic,and differentiated without requiring an original split between matter,meaning,and life.By placing qi beside agential realism[1]and vibrant materialism[2],the article builds a conceptual bridge between Chinese philosophy and contemporary cultural theory,while also challenging new materialism[3][20]to provincialize its own intellectual genealogy.The final section considers the implications of this bridge for posthumanism,especially debates on relational subjectivity,ecological ethics,and the more-than-human humanities. 展开更多

This study explores the challenges involved in preserving the materiality and memory of World War II(WWll)heritage sites in Trondheim,Norway.Structures such as military installations and bunkers hold significant cultural and historical value,yet their conservation involves facing a range of complexities between varying public perceptions,historical narratives,modern reuses,and physical durability.This study presents ten interconnected research questions designed to build a framework for understanding the various connections needed to address these complexities.By analysing Trondheim's case study,this research highlights the importance of integrating both tangible and intangible aspects,considering public perceptions and managing the site's appearance,use and identity to preserve historical narratives.The findings emphasise the value of cross-disciplinary collaboration in addressing the conservation of warbuilt heritage and propose strategies for balancing memory preservation with evolving urban contexts.This research also provides a database for better site management and future memory-related interventions. 展开更多

This study focuses on the principle of dual materiality and the stakeholder disclosure mechanism in corporate sustainability reports,and assesses the corporate social responsibility disclosure practices of multinational companies based on the Global Reporting Initiative(GRI)standards.The case study examined the 2022-2023 annual reports of ten companies and revealed a significant imbalance in stakeholder participation:the depth of information disclosure by investors and regulators was significantly greater than that by community organizations and civil society groups.At the level of dual materiality integration,environmental risk issues dominate,while social impact assessments such as human rights in the supply chain are relatively weak.The research reveals three major barriers to disclosure:information repetition leads to a decrease in reading efficiency,differences in compliance requirements between jurisdictions cause contradictions in disclosure,and the priority of reputation management weakens the integrity of negative information disclosure.Based on this,it is suggested to build an intelligent ESG management framework,optimize the disclosure focus through a dynamic stakeholder weight adjustment mechanism,and develop an automated compliance comparison tool to reduce institutional friction.This plan aims to improve the operability and credibility of corporate sustainability reports and provide theoretical support for the establishment of a unified global reporting standard. 展开更多

The multi-pass intermittent local loading process,which features a more flexible processing path,can further enhance the second material distribution during local loading,improve the formability of components,and reduce forming loads.However,the absence of compatible forming equipment makes it difficult to control the constraint in the unloaded zones during the forming process.This difficulty complicates coordination and control of deformation,particularly for asymmetric rib-web components.Additionally,the current implementation involves multi-fire heating,a long process flow,and high energy consumption,which limits the popularization and application of the local loading process.In this study,a new multi-pass local loading hydraulic forming apparatus that can quickly and reliably switch between heavy-load deformation and low-load constraint for different local loading sub-dies was developed.A 10-tonne laboratory prototype was developed,and the forming characteristics during the forming process as well as the response characteristics of the hydraulic system during the multi-pass intermittent local loading of rib-web component were investigated using numerical simulations and physical experiments.Results indicated that,compared to a whole loading process with the same initial geometry of billet,the total forming load(i.e.,the sum of loaded and restrained loads)is reduced by more than 40%with the local loading process,and by nearly 50%with multi-pass local loading.The multi-pass local loading process allows for more effective control of material flow compared to single-pass local loading,leading to improved cavity filling and reduced flow line disturbance.For a large-scale,complex titanium alloy bulkhead,the cavity filling problem was addressed by optimizing the multi-pass local loading path with an unequal thickness billet.The dynamic performance of the multi-pass local loading hydraulic system was found to be robust,with stable pressure transitions during motion and load switching for the sub-die(s).The dynamic characteristic of the hydraulic cylinder when switching from non-moving/unloaded state to a moving/loading state are consistent whether a load is present or not.However,the dynamic characteristics differ when switching from a moving/loading state to non-moving/unloaded state,showing opposite behavior.The developed hydraulic drive mechanism provides a way for implementation of multi-pass local loading without auxiliary operation and extra heating.The results of the study provide a foundation for the industrial production of large-scale,complex components with reduced force requirement and low-energy consumption. 展开更多

The pursuit of heat-resistant energetic materials(HREMs)with thermal stability beyond 450℃ presents a significant challenge that has yet to be achieved.In this work,we develop an innovative electronic delocalization strategy to design and synthesize a planar dizwitterionic diamino-bistriazolotetrazine,designated as TYX-1.The unique structural feature of TYX-1,including a nitrogen-rich fused ring system,planar conformation,and dizwitterionic configuration,combined with its hydrogen-bonded organic framework(HOF)structure,confer exceptional thermal stability(The onset temperature is 428℃,and the peak temperature is 473℃),high density(1.84 g/cm3),and remarkable detonation performance(detonation velocity:8616 m/s).Furthermore,TYX-1 exhibits an impressive insensitivity(impact sensitivity>40 J;friction sensitivity>360 N),surpassing all previously reported HREMs.Theoretical calculations and single-crystal clearly indicate that the delocalizedπelectrons within the dizwitterionic bistriazolotetrazine rings and the HOF structure of TYX-1 are pivotal in ensuring its high thermal stability and high energy density.The discovery of TYX-1 marks a significant advancement in the field of HREMs and is anticipated to catalyze substantial progress in various high-temperature applications reliant on energetic materials. 展开更多

Nickel-rich layered oxides are considered highly promising cathode materials for all-solid-state batteries(ASSBs)due to their high theoretical specific capacity and energy density.In this study,a comparison between polycrystalline and single-crystalline cathode materials was conducted.It was found that,during the charging process,ion transport at the interface of polycrystalline cathodes is significantly influenced by phase transitions and side reactions with the electrolyte,resulting in an irreversible increase in impedance after cycling.Furthermore,the structural stability of the cathode material affects internal ion diffusion kinetics,thereby influencing its electrochemical performance.Unlike single-crystalline materials,ion migration in polycrystalline materials must traverse anisotropic grain boundaries,which,due to anisotropic lattice contraction,evolve into intergranular cracks,leading to reduced ion diffusion kinetics and degraded electrochemical performance.In contrast,single-crystalline cathodes exhibit more stable interfacial resistance and uniform ion transport during charging,ensuring structural stability over longterm cycling.Consequently,at a 0.5 C rate,the single-crystalline cathode maintains a specific capacity of143 m Ah/g after 500 cycles,with a capacity retention of 89.2%,while preserving its intact single-crystal morphology.This study provides valuable new insights into the localized lithium-ion transport behavior in single-crystalline and polycrystalline cathode materials for sulfide-based all-solid-state batteries. 展开更多

To address the challenge of balancing thermal management and thermal runaway mitigation,it is crucial to explore effective methods for enhancing the safety of lithium-ion battery systems.Herein,an innovative hydrated salt composite phase change material(HSCPCM)with dual phase transition temperature zones has been proposed.This HSCPCM,denoted as SDMA10,combines hydrophilic modified expanded graphite,an acrylic emulsion coating,and eutectic hydrated salts to achieve leakage prevention,enhanced thermal stability,cycling stability,and superior phase change behavior.Battery modules incorporating SDMA10 demonstrate significant thermal control capabilities.Specifically,the cylindrical battery modules with SDMA10 can maintain maximum operating temperatures below 55°C at 4 C discharge rate,while prismatic battery modules can keep maximum operating temperatures below 65°C at 2 C discharge rate.In extreme battery overheating conditions simulated using heating plates,SDMA10 effectively suppresses thermal propagation.Even when the central heating plate reaches 300°C,the maximum temperature at the module edge heating plates remains below 85°C.Further,compared to organic composite phase change materials(CPCMs),the battery module with SDMA10 can further reduce the peak thermal runaway temperature by 93°C and delay the thermal runaway trigger time by 689 s,thereby significantly decreasing heat diffusion.Therefore,the designed HSCPCM integrates excellent latent heat storage and thermochemical storage capabilities,providing high thermal energy storage density within the thermal management and thermal runaway threshold temperature range.This research will offer a promising pathway for improving the thermal safety performance of battery packs in electric vehicles and other energy storage systems. 展开更多

Ultrasonic-Assisted Grinding(UAG)is a novel manufacturing technology that shows promising promise for use in processing Ceramic Matrix Composites(CMCs).Nevertheless,analyzing the material removal process of CMCs with multidirectional structure during UAG is challenging,impeding the progress and improvement of the UAG process.This work examined the impact of ultrasonic vibration on the dynamic mechanical characteristics during processing.Additionally,we experimentally elucidated the material removal mechanism of CMCs during the scratching process under the influence of vertical vibration.The results indicate that the introduction of ultrasonic vibration causes a strain rate effect,resulting in a modification of the material removal mechanism,subsequently impacting the processing quality.Ultrasonic vibration increases the dynamic strength and brittleness of the fibers in CMCs,leading to more cracks at fracture,which changes from the original bending fracture to shear fracture.In addition,ultrasonic vibration can effectively inhibit the impact of scratching depth and anisotropy on the removal mechanism of CMCs,resulting in a more uniform surface of CMCs after processing. 展开更多

The reactive materials filled structure(RMFS)is a structural penetrator that replaces high explosive(HE)with reactive materials,presenting a novel self-distributed initiation,multiple deflagrations behavior during penetrating multi-layered plates,and generating a multipeak overpressure behind the plates.Here analytical models of RMFS self-distributed energy release and equivalent deflagration are developed.The multipeak overpressure formation model based on the single deflagration overpressure expression was promoted.The impact tests of RMFS on multi-layered plates at 584 m/s,616 m/s,and819 m/s were performed to validate the analytical model.Further,the influence of a single overpressure peak and time intervals versus impact velocity is discussed.The analysis results indicate that the deflagration happened within 20.68 mm behind the plate,the initial impact velocity and plate thickness are the crucial factors that dominate the self-distributed multipeak overpressure effect.Three formation patterns of multipeak overpressure are proposed. 展开更多

Asymmetric supercapacitors(ASCs)are promising candidates for high-power output applications;however,their theoretical capacity remains largely unrealized owing to the low specific capacity of carbon negative electrodes.Traditional strategies for enhancing the specific capacity of carbon via structural optimization often compromise the tap density,electrical conductivity,and rate performance of the material.In this study,we address this bottleneck by incorporating 4-hydroxy-2,2,6,6-tetramethylpiperidinyloxyl(4OT)as a redox mediator into the electrolyte to construct ASCs with well-matched capacities and potential windows between the two electrodes.With 50,100,and 200 mM 4OT added in electrolytes,the activated carbon electrodes achieve specific capacities of 113,181,and 263 mAh·g-1at 2 A·g-1.The Ni3S2/CoNi2S4positive electrode exhibited a specific capacity of 415 mAh·g-1,benefiting from its superior electrical conductivity,abundant active sites,and enhanced electrochemical activity.Notably,introducing 4OT to the electrolyte effectively balances the capacity and potential window of the two electrodes.Consequently,the as-assembled ASCs deliver a maximum energy density of55 Wh·kg-1,which surpasses previously reported values.Our work demonstrates that the rational selection and application of redox mediators have great potential for balancing electrode capacity and boosting the energy density of high-performance ASCs. 展开更多

The potential of hydroxyapatite(HA)nanoparticles as an alternative fertilizer has been extensively explored to mitigate the negative effects of conventional fertilizers on soil health.However,their low solubility in soil remains a significant challenge as this property reduces their efficiency for controlled nutrient delivery.To address this challenge,organic-inorganic nanocomposites,particularly HA-biopolymer-based nanofertilizers,have been proposed.These biocomposites combine the nutrient-rich feature of HA with the improved solubility and controlled-release ability provided by biopolymers,while also enhancing soil interaction to ensure more efficient and sustainable fertilization.The polymeric phase plays a key role in nutrient solubilization kinetics by facilitating microbial release,minimizing the need for frequent application,and reducing the toxicity to plants,which altogether reduces the overall environmental implications of fertilizer application.Despite recent advances,several key scientific gaps remain unaddressed,including the optimization of synthesis methods,the role of polymer composition in nutrient release kinetics,and the long-term effects of these nanofertilizers on soil health and plant productivity.This review provides a comprehensive analysis of the recent progress and prospects for HA-based nanofertilizers,emphasizing synthesis techniques,structural properties,and performance in soil environments.Additionally,it highlights the need for tailored approaches to optimize nutrient release profiles,ensuring sustained nutrient availability,reduced environmental impact,and enhanced agricultural productivity.By identifying these knowledge gaps,this review aims to guide future research toward the design of next-generation HA-biopolymer nanocomposites with improved efficiency and sustainability compared to existing ones. 展开更多

Thermoelectric (TE) materials enable precise, noiseless, and moving-part-free waste heat recovery and solid-state refrigeration through the Seebeck and Peltier effects [1–3]. The efficiency of TE materials is typically evaluated by a dimensionless figure of merit (ZT = S2σT/(κe+ κl)), which depends on the delicate interplay among the electrical conductivity (σ), Seebeck coefficient (S), lattice thermal conductivity (κl), and electronic thermal conductivity (κe) [4]. 展开更多

The mid-infrared(MIR)spectral window,typically spanning wavelengths from 2.5 to 20μm(or wave numbers 500-4000 cm−1),constitutes a pivotal domain of the electromagnetic spectrum,where molecular vibrational and rotational transitions enable precise spectroscopic identification and tunable thermal radiation modulation.Mastery over this spectral range underpins a broad and growing suite of technologies,encompassing high-resolution MIR imaging and spectroscopic gas sensing,advanced thermal management via radiative cooling/heating and dynamic emissivity control,integrated photonic platforms featuring low-loss optical windows and waveguides,as well as MIR laser systems that leverage broadband transparency for efficient frequency conversion and beam delivery.High MIR transmittance(TMIR)is therefore essential for driving MIR photonic innovations,enabling efficient photon transmission,modulation,and targeted heat control.Yet,the fundamental interplay among material structure,photonic/electronic behavior,and MIR optical performance remains underexplored.This review comprehensively evaluates high TMIR materials,with an emphasis on their optical mechanisms,structural attributes,synthesis routes,and performance benchmarks.By elucidating structure-property relationships and offering design strategies for MIR transparency,this review provides a roadmap for developing high-performance MIR transparent materials for advanced thermal management,infrared optics,and next-generation photonic systems. 展开更多

Cement stands as a dominant contributor to global energy consumption and carbon emissions in the construction industry.With the upgrading of infrastructure and the improvement of building standards,traditional cement fails to reconcile ecological responsibility with advanced functional performance.By incorporating tailored fillers into cement matrices,the resulting composites achieve enhanced thermoelectric(TE)conversion capabilities.These materials can harness solar radiation from building envelopes and recover waste heat from indoor thermal gradients,facilitating bidirectional energy conversion.This review offers a comprehensive and timely overview of cementbased thermoelectric materials(CTEMs),integrating material design,device fabrication,and diverse applications into a holistic perspective.It summarizes recent advancements in TE performance enhancement,encompassing fillers optimization and matrices innovation.Additionally,the review consolidates fabrication strategies and performance evaluations of cement-based thermoelectric devices(CTEDs),providing detailed discussions on their roles in monitoring and protection,energy harvesting,and smart building.We also address sustainability,durability,and lifecycle considerations of CTEMs,which are essential for real-world deployment.Finally,we outline future research directions in materials design,device engineering,and scalable manufacturing to foster the practical application of CTEMs in sustainable and intelligent infrastructure. 展开更多
