Evolution of temperature fields and heat transfer mechanisms in concrete structures subjected to hydrogen jet flame impingement

To clarify the temperature field evolution and heat transfer mechanisms of concrete structures under hydrogen jet flames, a self-developed hydrogen gas jet flame exposure platform has been established. C30 concrete specimens were tested under hydrogen mass flow rates of 0.025, 0....

Microscale mass transfer mechanisms and interfacial behaviors of Janus membranes in vacuum membrane distillation for solution regeneration: A molecular dynamics study

Membrane distillation-based absorption refrigeration (MDAR) utilizes low-grade heat for solution regeneration. However, processing highly concentrated (>50 wt%) LiBr solutions imposes a trade-off between liquid exclusion and water transport in conventional hydrophobic membranes....

Synthesis of Fe-Co Bimetallic Supported on Cotton Residue Biochar: Catalytic Performance and Mechanistic Investigation for CO2 Hydrogenation

Biochar carriers were prepared from cotton residue waste, and Fe-Co bimetallic catalysts with different ratios were constructed using impregnation method. Their catalytic performance in CO2 hydrogenation to hydrocarbons was investigated. The structural evolution and catalytic beh...

A security risk assessment approach based on improved PSO-BPNN for intelligent network information systems

Smart cities have brought numerous benefits to improve citizens’ living quality, but they have also brought greater cyber security challenges. Risk assessment is a commonly used approach to enhance the cyber security of information systems. However, information systems in smart c...

Sub-diffraction far-field dark-field nanoscopy via low-index microlens and deep learning

Far-field imaging methods capable of resolving samples beyond the diffraction limit of light are essential for understanding the intricate details of molecular interactions in physical chemistry and biophysics. Here, we demonstrate the use of low-index microspheres to enhance the...
