Summary: The study demonstrates that the thermo-hydro-mechanical coupling model considering the deformation of fractal fractures is remarkably robust for modeling fracture opening and closing under coupling conditions. The evolution of fracture permeability presents certain heterogeneity related to fractal dimension, in-situ stress, and geothermal wells layout. Fractures with larger fractal dimension can interact more fully with the bedrock and further affect the thermal breakthrough.

Summary: The article introduces a new method called gradient-enhanced physics-informed neural networks (gPINNs) to improve the accuracy of PINNs. gPINNs leverage the gradient information of the PDE residual to enhance the loss function. Experimental results demonstrate that gPINNs outperform traditional PINN with fewer training points.

Summary: The purpose of this investigation is to theoretically study the effect of unsteady electroosmotic flow (EOF) in an incompressible fractional second-grade fluid with low-density mixtures of two spherical nanoparticles, copper and titanium. Analytical and numerical methods are used to obtain solutions for the velocity and heat equations, and the variations of velocity and heat transfer with respect to different parameters are presented graphically. This research has theoretical implications for biofluid-based microfluidic transport systems.

Summary: Thermal stratification is the main cause of thermal fatigue failure in rectangular T-junctions. By setting an impeller with a constant rotation speed, the mixing behavior of hot and cold fluids can be improved, and various flow patterns including wall jet, deflecting jet, and impinging jet can be observed. The relationship between mixing length and blade diameter is not monotonic, and the optimal operating point is around D-p* = 0.5 for impellers with 2 blades.

Summary: This article comprehensively reviews the electrochemical performances and stabilities of SOFCs operating on various fuels. Although comparable power densities to hydrogen were frequently obtained, degradation problems induced by these fuels influence the long-term stable operation of SOFCs. Potential strategies from three perspectives of thermodynamics, kinetics and structure are proposed to solve degradation issues. The remaining challenges and future prospects of SOFCs fed by each fuel are separately elaborated.
