Precise control over organic reaction dynamic requires in-situ insight into temperature and concentration variations.However,conventional detection strategies,often relying on off-line or decoupled methods,suffer from delayed responses and poor temporal synchronization.Herein,we propose a bifunctional single-fiber sensor based on Ge5As25Se30Te40 chalcogenide glass,which seamlessly integrates fiber evanescent wave spectroscopy for chemical fingerprinting identification with a thermoresistive effect for thermal sensing.It exhibits exceptional performance with a rapid temperature response(~2.6 s)and a high temperature sensitivity(jTCRj~4.07%K-1).Validated through the in-situ monitoring of ethyl butyrate synthesis,the single-fiber sensor effectively tracked reaction evolution and thermal distinctness,providing reliable guidance for process optimization and control.With its label-free detection,structural simplicity,and high sensitivity,this proposed strategy represents a robust process analytical technology tool for monitoring complex organic reactions. 展开更多

Deep-sea mining is increasingly viewed as a potential source of critical metals needed for the global energy transition,including those used in batteries,electric mobility,renewable power systems,and grid infrastructure.The deep-sea mining faces a critical environmental challenge:sediment plumes generated by collector vehicles disturbing the seabed.These plumes,composed of fine-grained deep-sea clays,can persist for extended periods and disperse across vast oceanic areas,posing a threat to benthic ecosystems.Current plume management predominantly adopts a reactive approach,focusing on monitoring and containment rather than addressing the root cause.This paper argues that effective plume control necessitates an understanding and active management of the geotechnical properties of deep-sea sediments.We find that the unique characteristics of deep-sea sedi-ments,including high water content,fine particle size,flocculated microstructure,high surface activity,and the interactions between particles and hydrodynamics,are not only the origin of the plume issue but also the key to its resolution.Targeting three fundamental pathways,namely reducing particle entrainment,limiting transport range,and shortening suspension duration,we propose a comprehensive mitigation framework grounded in geotechnical principles.We conclude that a transition from passive monitoring to proactive particle-level intervention is essential for reducing plume-related environmental risks and for enabling the environmentally and commercially sustainable extraction of energy-critical metals from the deep sea. 展开更多

All-solid-state lithium-ion batteries(ASSLIBs)have emerged as a new generation of energy storage systems,owing to their high energy density and safety advantages.However,their extensive application is hindered by both the insufficient ionic conductivity of solid electrolytes and the interfacial mismatch between electrolytes and electrodes.To address this issue,we developed glassy ASSLIBs by harmoniously coupling glass-ceramic electrolytes with vanadium phosphoborate glass electrodes.The electrolytes were prepared from an aluminophosphate glass system through controlled crystallization.The optimized electrolyte exhibited a high ionic conductivity(1.15×10-4 S cm-1)and a low activation energy(0.23 eV)for Li+diffusion.The interfacial compatibility between the glass electrode and the glass-ceramic electrolyte enabled fast electron/ion transport in an assembled full cell(with a Li metal anode).The derived glassy battery delivered an initial discharge capacity of 907 mA h g-1at 0.1 A g-1and a capacity of 228 mA h g-1after 500 cycles,along with superior rate performance.Thus,this study offers a promising strategy for advancing ASSLIBs. 展开更多

Improvements to body-surface physiological monitoring ability including real-time,accuracy and integration,are essential to meet the expansive demands for personal healthcare.As part of this,simultaneous monitoring of sweat metabolites and body temperature offers an exciting path to maximizing diagnostic precision and minimizing morbidity rates.Herein,we report a high-performance biomarker-temperature sensor made of a single As3Se5Te2chalcogenide glass fiber to monitor physiology evolution on body-surface.The sensor integrates efficient thermal resistance and fiber evanescent wave effects,permitting the independent sensing of temperature and biomarkers with an ultrahigh temperature coefficient of resistance(−5.84%K–1),rapid temperature response(0.3 s)and excellent IR sensing sensitivity.Moreover,by attaching a fiber to the wrist,we demonstrate simultaneous observation of both sweat metabolite(urea and lactate)and temperature changes during exercise.This illuminating sensing method will provide crucial capabilities in physiological monitoring and pave the way for advanced personalized diagnostic. 展开更多
