In recent years lithium-air batteries captured worldwide attention because of their high energy density. Solid state electrolytes is one of the main components of lithium-air batteries. Lithium almunium titanium phosphate(LATP) is a nasicon type ion conduction which may be of great potential as solid electrolyte. The object of this thesis was the preparation of LATP solid electrolyte which can be used in a lithium-air battery. To reach this goal LATP powder was synthesized using a solution-based method and an appropriate crystallization temperature was selected based on obtained results of X-ray diffraction analysis. In the next step solid electrolytes was prepared under different pressing... 

Rainfall is one of the primary factors contributing to slope instability, as it alters the hydraulic and mechanical properties of soil. Infiltration reduces matric suction, thereby decreasing shear strength and increasing the possibility of rainfall-induced landslides. Vegetation influences slope stability through both hydrological and mechanical reinforcement mechanisms by modifying suction and enhancing cohesion. Consequently, the stability of rainfall-triggered slopes depends on multiple factors, including initial slope conditions, rainfall intensity and duration, soil type, groundwater conditions, slope geometry, and vegetation cover. Root absorbed water reduces soil moisture and...
