Stimuli-responsive micro/nanostructures that can dynamically and reversibly adapt their configurations according to external stimuli have stimulated a wide scope of engineering applications, ranging from material surface micromanipulations. However, it remains challenge achieve precise local control the actuation realize applications require heterogeneous on-demand responses. Here, new experimental technique is developed for large arrays hybrid magnetic micropillars using simple field. By...

Guide vanes (GVs) are one of the components Francis turbine that most vulnerable to erosion. Presence hard minerals including feldspar and quartz cause erosion on surface GVs. This results in damage disturbances functioning turbine. Computational Fluid Dynamics (CFD) methods useful estimate but dependent significantly models used for simulations. A three guide vane cascade (3GV) rig is a simplified setup recreates flow around Previous studies have visualize secondary flows GVs using Particle...

The role of notch stress and surface defects on fatigue crack initiation small-crack propagation behavior has been investigated using groove simulation specimens. naturally initiated growth tests have performed a FGH4099 superalloy at 500 °C 700 °C. findings indicate that elevated testing temperature significantly reduced the proportion life, with less pronounced effect life for cracks to grow First Engineering Crack size. Competing modes were observed in test location maximum principal was...

Deep drilling can lead to the encounter of complex geological conditions, with significant overburden pressure leading a narrow safety window for mud density. In this study, we deviated wellbore instability conditions using Mohr–Coulomb and tensile failure criteria, solving collapse, shear, fracture Newton’s method. The safe density is defined between maximum value pore collapse pressures minimum shear pressures. analysis Anderson fault stress model, utilizing method, enables comprehensive...

Carrier gas is known as the medium to inject cold sprayed powders into main driving flow inside nozzle. Hence, properties and conditions of carrier should be great importance particle motion behaviour then deposition process. In this study, effect temperature on acceleration in spray process was investigated by both numerical experimental methods. It found that supersonic consequent are significantly influenced temperature, more specifically, higher results impact velocity. addition, because...

Photocatalytic hydrogen peroxide (H2O2) production will become a burgeoning strategy for solar energy utilization by selective oxygen reduction reaction (ORR). Polymeric carbon nitride (PCN) shows relatively high two-electron ORR selectivity H2O2 but still limited low efficiency due to slow exciton dissociation. Herein, we constructed heptazine/triazine layer stacked heterojunction with fluorine/potassium (F/K) dual sites (FKHTCN). The introduction of F/K not only can regulate components...
