Abstract: In this paper, the femtosecond laser ablation of silicon is investigated by a twodimensional hydrodynamic model. The ablation depth of the silicon wafer ablated in air at different laser intensities is calculated, and the ...

Abstract: AbstractUrbanization modifies atmospheric energy and moisture balances, forming distinct features [e.g., urban heat islands (UHIs) and enhanced or decreased precipitation]. These produce significant challenges to science ...
