As illustrated in Figure 15a, the CS (polished) specimen is smooth and has no corrosion product on the CS site (85) . As depicted in Figure 15b, the CS immersed in well water is found to be rough with corrosion product on the CS surface, as well as cracks and damages (86) . ...

As depicted in Figure 15b, the CS immersed in well water is found to be rough with corrosion product on the CS surface, as well as cracks and damages (86) . Because the CS immersed in blank system contains AO (500ppm) and Zn 2+ (30ppm), the surface of the CS becomes smoother and less damaged, as shown in Figure 15c. ...

Background
Traumatic brain injury is one of the most common forms of trauma and causes significant morbidity and mortality. Kencur (Kaempferia galanga L.) ethanolic extract is known to contain substances that could theoretically inhibit unfavourable cellular processes, including oxidative stress and inflammation. This research aimed to study Kencur...

Adsorption was an available way to eliminate Tetracycline (TC) from waste water. Suaeda biochar (800SBC) and iron modified biochar (Fe-800SBC) were prepared using pyrolysis under oxygen-limiting conditions. BET and SEM showed that the surface of Fe-800SBC was rougher, and the specific surface area (SBET) was 7 times that of 800SBC. There existed pore filling, ion exchange, metal ion complexation, hydrogen bonds and cation-π interaction mechanism. Both 800SBC and Fe-800SBC conformed to quasi-second-order kinetics model, belonged to chemisorption. Fe-800SBC conformed to Elovich model too. The adsorption process of 800SBC conformed to Freundlich and Sips L-F models, Fe-800SBC conformed to the Sips L-F and Temkin models, identifying the presence of physical and chemical adsorption during adsorption. Response surface method (RSM) was used to optimize important process parameters. The quadratic model was sufficient to predict TC removal response in the range of studied parameters.
