Mass transfer has been studied at rotating cylinder electrodes of expanded metal using the reduction of ferricyanide as test reaction. The experimental data are well correlated by an empirical expression between the Sherwood ...

The removal of cadmium from dilute solutions using a continuous undivided electrochemical reactor with a rotating cylinder cathode of expanded metal is analysed. The effects of cathodic applied potential, size and orientation ...

The interest in metal sulfide precipitation has recently increased given its capacity to efficiently recover several metals and metalloids from different aqueous sources, including wastewaters and hydrometallurgical ...

Among the possible complications of bariatric surgery, fistula and partial dehiscence of the gastric suture are well known. Reoperation often is required but results in significant morbidity. Endoscopic treatment of some ...

Machines and tools that assist in the mechanical conformation process are present in most metal-mechanical industries and aim to change the material's geometry through applied forces. Due to the need for machinery to expand ...

The purpose of the current research was to identify and describe the main genetic determinants involved in bacterial resistance to heavy metals, as well as their potential use at a biotechnological and environmental level. ...
