After gold recovery using silicon powder from an ammonium thiosulfate leaching solution containing copper（II）sulfate（oxidizing agent for dissolution）, copper was also recovered. a certain period of time, redissolution occurred. Then redissolved. The depletion in the during process leads to redissolution.

Abstract. Although the anthropogenic emissions of SO2 have decreased significantly in China, decrease SO42- PM2.5 is much smaller than that SO2. This implies an enhanced formation rate ambient air, and mechanism still under debate. work investigated particulate sulfate based on statistical analysis long-term observations Shijiazhuang Beijing supported with flow tube experiments. Our main findin...

Solid-state cooling using barocaloric materials is a promising avenue for eco-friendly, inexpensive and highly efficient cooling. To design compounds ready deployment, it essential to understand their thermodynamic behaviour under working conditions. this end, we have studied the rotational dynamics in molecular-ionic crystal ammonium sulfate pressure, providing detailed insight into origin of ...

Identyfikacja i przekład ironii stanowi jedno z najtrudniejszych wyzwań dla tłumacza. Szczególnie dotyczy to tłumaczy literatury pięknej, gdyż jak wskazuje M. Głowiński: „Ironia literacka – jest domeną różnorodności” potrafi umykać uwadze nawet profesjonalnych krytyków. W niniejszym artykule uwaga została skoncentrowana na komponencie emocjonalnym ironii. Przeprowadzając lingwistyczną analizę w...
