Phenotype-dependent regulation of the system x<sub>C</sub>- cystine/glutamate exchanger by glutathione levels in rat astrocyte primary cultures
The system x<sub>C</sub><super>-</super> (Sx<sub>C</sub><super>-</super>) transporter functions under normal physiological conditions in astrocytes to mediate the exchange of extracellular cystine (L-Cys<sub>2</sub>) for intracellular glutamate (L-Glu). The internalized L-Cys<sub>2</sub> serves as …

Investigation of solvent-extraction options for zinc recovery from high chloride solutions for the Anglo Research Zinc process
… a chloride leach. Solvent extraction (SX) is being considered as a potential leach liquor purification option for the process. It is envisaged that the pregnant leach solution (PLS) will be sent to SX after which zinc will be recovered as plate metal and chlorine gas generated from an …

Anwendungsgrenzen von modernen Nickelbasis-Superlegierungen in effusionsgekühlten Bauteilen zukünftiger Gasturbinen
… behaviour of two nickel-base superalloys, CMSX-4 and SX CM186LC, have been investigated. Hot-tensile, tensile creep and low-cycle-fatigue tests have been performed on single crystal and directionally solidified variants at temperatures up to 1000°C to compare their tensile-, creep- and …

Extraction of Rare Earth Elements from Aqueous Solutions by Using Hydrometallurgical Techniques
… Within hydrometallurgy, the solvent extraction (SX) method plays a crucial part in the purification of rare earth elements (REE) from concentrated solutions through efficient elemental extraction and high purity. Due to its remarkable extraction capacity and straightforward implementation, the SX …
