The widespread occurrence of perfluorooctanoic acid (PFOA) and its detrimental environmental impacts have become a major focus of global attention. This study focused on the synthesis of bimetallic CoMn$_2$O$_4$ spinel by using the simple precipitation method followed by calcination at 550 °C. The p ...

Propylene carbonate (PC) is a high-value cyclic carbonate that has become more and more essential in green solvents, polymer processing, gas purification, pharmaceutical intermediates, and lithium-ion battery electrolytes. In this work, we have developed a sustainable and phosgene-free synthesis of ...
