Abstract Silver bismuth sulfide (AgBiS 2 ) is showing impressive thermoelectric and photovoltaic properties has a high potential to replace toxic cadmium or lead containing semiconductors in many applications. Herein, we report on synthesis route for AgBiS nanocrystals applying metal xanthates as precursors. could not be used so far solution‐based syntheses Ag‐containing they are typically inso...

The southern part of Skull Valley has potential for shallowly buried mineral deposits. The most likely deposit type is either skarn/porphyry copper deposits, perhaps with surrounding polymetallic lead-zinc-silver replacement deposits or "distal disseminated" gold-silver deposits. The area (1) is structurally complex with both thrust and high-angle faults, (2) contains lithologic units favorable...

Background: Precious objects made of silver and/or its alloys tarnish and become black when exposed to ambient atmospheres containing moisture and ppb-amounts of H2S. Such objects usually contain small but variable amounts of copper as alloying constituent and this affects the corrosion process due to a preferential oxidation of copper. However the visual appearance of the formed tarnishing lay...
