    Comparative study on cutting performance of conventional and ultrasonic-assisted bi-directional helical milling of CFRP

    Compared with the conventional drilling, the helical milling has obvious advantages in making holes of carbon fiber-reinforced plastic (CFRP). Nevertheless, the rapid wear of cutting edges readily causes some ...

    Mechanism of photostimulated luminescence: BaFCl:Eu2+

    We propose a new parallel model based on the analysis of photostimulated luminescence (PSL) process and existing theoretical models. While solving this model, the general expression for PSL is gained. BaFCl:Eu2+,...
