Ultraviolet irradiation penetration depth on TiO2 [PDF]

Communications Chemistry
High-energy ultraviolet (UVC) irradiation of metal oxides (MOs, e.g., TiO2) results in photoinduced surface oxygen vacancies (PI-SOVs), which can change the charge carrier (e.g., electrons and holes) migration dynamics.

Influence of parameters on the ultimate penetration depth of a double-plate vertically loaded anchor in soft clay

Frontiers in Materials, 2023
To make a new type of double-plate vertically loaded anchor (DPVLA) penetrate into clay deeper, the influence of parameters on the ultimate penetration depth of DPVLAs in soft clay should be investigated.

Mass Loss and Penetration Depth of Hypervelocity Projectiles

Shock and Vibration, 2021
Numerous investigations recorded a dramatic decrease in penetration depth at hypervelocity. The decrease is due to the severe mass loss of the projectile. The mechanics of mass loss are complicated, so the entirely theoretical model is still absent.
