Opis:
Practical engineering education in space technology is a major challenge. TU Berlin has collected many years of experience in educating prospective space system engineers. With its history of developing and operating real space missions and its many ongoing research activities in the field, students are provided the opportunity to experience space technology. The Chair of Space Technology adresses the issue of innovative education constantly. Novel methods in hands-on education that arise through new technologies and trends are embedded into the curricula. A current project envisages the development of the autonomous planetary rover SEAR (Small Explora tion Assistant Rover) with students. With SEAR, TU Berlin will participate in the SpaceBot Cup, a planetary exploration competion aimed to push forward key technologies in space robotics. To comply with the strict development timeline of nine months, educational methods for efficient utilization of student’s ressources and provision of high-level education are applied.

Opis:
In this study, solidification/stabilization (S/S) of electric arc furnace dust (EAFD) which is generated during the production of steel from scrap metals and classified as hazardous waste were investigated by using different ratios of cement and low grade MgO (LG MgO) as binding agents. Type I PC 42.5 R portland cement and LG MgO which contains 70–80% MgO were used. S/S blocks that contain different ratios of binding agents which have 1/0.5 – 1/1 – 1/2 – 1/3 – 1/4 – 1/5 cement/LG MgO ratio and S/S blocks which contain only cement and no LG MgO agents were prepared. These blocks, which contain 3 different waste ratios according to weight, 20%, 30% and 40% respectively, were produced and exposed to 28-day water purification. At the end of the purification process, S/S blocks were extracted using TCLP (Toxicity Characteristic Leaching Procedure) tests in order to determine the leaching behavior of Zn, Pb, and Cd in S/S blocks. By the end of this study, it was concluded that the recovery of EAFD is possible and applicable by immobilization. The findings of the study concluded that environmental performances or structural properties of blocks contain 30% waste by weight are suitable. This method is a proper one for recovering and treatment of EAFD with mixture of cement and LG MgO.
