Abstract: Abstract Resource-based urban areas face a critical challenge: cutting high carbon emissions from long-term resource exploitation while transforming economically and meeting dual carbon goals. Since mixed land use affects ...

Abstract: A numerical method is proposed to study load and the environment couple effect during the service of a concrete bridge. By studying the corrosion process of reinforcement bars, the strain of the bars is decomposed into two ...

Abstract: Abstract. A novel externally pressurized porous gas journal bearing with herringbone grooves is proposed to provide a larger load-carrying capacity, especially under high compressibility number conditions. The steady-state ...

Abstract: A series of Y0.2 Zrx Ce0.8−x O1.9 compounds (0 ≤ x ≤ 0.6) had been prepared by the modified sol-gel method and characterized by powder X-ray diffraction, thermo-gravimetric analysis, four-probe ...

Abstract: A simple, low-cost testing method is proposed for fuel cell hardware development. A perforated aluminum foil with an array of small holes covered with carbon paper or cloth replaces the membrane ...

Abstract: Methanol crossover largely affects the efficiency of power generation in the direct methanol fuel cell. As the methanol crosses over through the membrane, the methanol oxidizes at the cathode, ...

Abstract: The flow-field design of direct methanol fuel cells (DMFCs) is an important subject about DMFC performance. Flow fields play an important role in the ability to transport fuel and drive out ...

Abstract: To cope with the phenomenon of moisture imbalances in subgrades due to excavation, the resistivity of different excavation subgrades (deep excavation section, shallow excavation section, and cut-and-fill transition section) ...

Abstract: The performances of direct methanol fuel cells are largely dependent on the methanol crossover, while the amount of methanol crossover is reported to strongly rely on membrane materials and ...
