Copper substitutions in synthetic miargyrite α-AgSbS2 mineral: Synthesis, characterization and dielectrical properties
The nominal compositions Ag0.8Cu0.2SbS2 and Ag0.7Cu0.3SbS2 have been synthesized by conventional ceramic solid-state reaction at high temperature. X-ray diffraction (XRD) and scanning electronExpand
Magnetic properties and crystal structure of solid‐solution Cu2MnxFe1−xSnS4 chalcogenides with stannite‐type structure
New solid solutions Cu2MnxFe1−xSnS4 were prepared by direct combination of the corresponding elements at 850 °C. The crystal structure of Cu2Mn0.4Fe0.6SnS4 was determined by single-crystal X-rayExpand
Ultrasound-assisted synthesis of novel chalcone, heterochalcone and bis-chalcone derivatives and the evaluation of their antioxidant properties and as acetylcholinesterase inhibitors.
The chalcone and bis-chalcone derivatives have been synthesized under sonication conditions via Claisen-Schmidt condensation with KOH in ethanol at room temperature (20-89%). The structures wereExpand
Development of an iron-selective antioxidant probe with protective effects on neuronal function
Iron accumulation, oxidative stress and calcium signaling dysregulation are common pathognomonic signs of several neurodegenerative diseases, including Parkinson´s and Alzheimer’s diseases,Expand
