Introduction: When a large hypervelocity impact occurs on a planetary body such as Mars, the kinetic energy of the impactor is partitioned primarily into 1) kinetic energy of the planetary crust and mantle as they deform and flow in response to the impact, 2) heating, melting and vaporization of impactor, crust and mantle material and 3) shockwaves that travel throughout the entire volume of th...

The recycling of mineral tailings is an important research topic. In this work, composite material was prepared using vanadium titanomagnetite (VTM) tailings, kaolin and sodium silicate, used as a photocatalyst for photocatalytic degradation organic dyes. results showed that the has good performance on rhodamine B in solution within few minutes. synthesized materials were characterized by XRF, ...
