Microbial isolation and characterization from two flex lines from the urine processor assembly onboard the International Space Station

Urine, humidity condensate, and other sources of non-potable water are processed onboard the Cushions International Space Station (ISS) by the Water Recovery System (WRS) yielding potable water.While some means of microbial control are in place, including a phosphoric acid/hexavalent chromium urine pretreatment solution, many areas within the WRS a

Recrystallization of Cu-30Zn brass during friction stir welding

The recrystallization process of Cu-30Zn brass during friction stir welding (FSW) was investigated.The microstructural evolution in the stirring period and the subsequent normal air-cooling period were separately studied by using stop-action technology, liquid nitrogen cooling, and subsequent heat treatment.During the stirring period, the initial l
