Circular Economy in Food Supply Chains: Comprehending the Paradigm and Redefining Future Research Through a Multidisciplinary Review of Reviews

Business Strategy and the Environment, EarlyView.
ABSTRACT The inefficiencies of the global food system necessitate a shift towards a circular economy (CE) in food supply chains (FSCs). While research on CE in FSCs spans multiple disciplines, it often remains siloed within respective disciplinary boundaries, limiting its practical impact.

Experimental study on characteristics of methane-coal dust explosions and the spatiotemporal evolution of flow field in early flame

Case Studies in Thermal Engineering
To understand the explosion characteristics of methane-lignite coal dust mixtures and the spatiotemporal evolution of the early flame flow field, explosion pressure, OH* emission spectra, and early flame schlieren images were captured in a 60L constant ...

An Ultra-Low-Power-Consumption Urban Sewer Methane Concentration Monitoring System Based on Ultrasound

Applied Sciences, 2023
Methane is the main cause of sewer explosion accidents, and the available monitoring methods mainly use portable gas sensors for on-site detection. However, these methods cannot grasp the dynamic changes in methane in a sewer in real time or make good ...

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Unveiling Synergistic CuAuAg Nanoparticles on CuO for High‐Yield CO2 Electroreduction

Carbon Energy, EarlyView.
Pulsed laser irradiation in liquid synthesis was employed to fabricate a trimetallic catalyst composed of CuAuAg nanoparticles uniformly decorated on CuO nanosheets (CuAuAg/CuO composite). This catalyst exhibits remarkable electrocatalytic performance for the reduction of CO2 to CO, achieving a high CO yield rate of 5.1 mmol h−1 cm−2 and a Faradaic ...

Vented Hybrid Explosions of Methane and Coal Dust

Proceedings of the Seventh International Seminar Fire and Explosion Hazards, 2013
The interaction of a vented methane explosion flame front (and induced flow) with a coal dust layer just prior to the vent exit, was experimentally investigated in a small cylindrical explosion vessel with two different open vent areas at low level, using different methane/air mixtures and different amounts of coal in the layer.

Sustainable Germanium Recovery From Germanium Dioxide via Halogen‐Free Chemical Vapor Transport

Chemistry – A European Journal, EarlyView.
Recovery of the critical element Ge from GeO2 and SiO2/GeO2 mixtures was investigated based on an endothermic chemical vapor transport via GeO, formed with natural gas or a hydrogen(10%)‑argon(90%) mixture and water vapor. (This picture was partly created with AI, engine: Adobe Firefly).

Study on characteristics of methane explosion suppression by N2-water mist gas-liquid two-phase coupling

Meikuang Anquan
To investigate the effect of N2-water mist gas-liquid two-phase coupling on the propagation of methane explosion flames, based on a self-made mesoscale shock wave pipeline, we investigate the effect of N2 at different injection pressures on the ...
