Due to the difficulty of oilfield produced water treatment and low efficiency of coagulation technology. A more efficient treatment technology was necessity. Produced water treatment by ozone enhanced coagulation was investigated in this study in order to develop a new method for oilfield produced water treatment. The results showed that addition of ozone could reduce the dosage of coagulant (PAC)...
Nowadays, there are certain tasks that are not automated and still rely on visual inspection of an expert. In the case of the steel industry, the estimation of the deoxidation and desulfuration of steel is done at the Ladle Furnace by an expert and it is latterly analyzed in a laboratory by the use of modern spectrographs. However, the automation of this process does not constitute a trivial task...
During Ti/TiN barrier metallization of a shared contact in SRAM, an NH3 soak treatment selectively deoxidized silicon oxide on NiSi at the gate shoulder, improving the resistance of the contact. This deoxidizing NH3 soak treatment drastically reduced the drawbacks of conventional NH3 plasma treatment: plasma-induced damage of gate oxide and excessive nitridation of Ti/TiN. Although NH3 gas does not...
