“Is there a mouthwash or toothpaste that removes this plaque and calculus?” asks the patient undergoing periodontal treatment, particularly one who has not succeeded in removing plaque with a toothbrush and dental floss. In reviewing the literature on this subject it was found that scientists and clinical researchers are making a determined effort to understand plaque, while at the same time te...

Sn-doped Zinc oxide is experimented in this research work using sol-gel method. The sol is here constructed using the zinc-acetate dehydrate and tin chloride. Once the solution is prepared, the analysis is performed for XRD patterns at different temperature values. The intensity analysis is been performed for different annealing temperatures at different wavelength. The results show that as the...

The formation of protective layers on copper, zinc and copper-zinc (Cu-10Zn and Cu-40Zn) alloys at open circuit potential in aerated, near neutral 0.5 M NaCl solution containing benzotriazole (BTA) was studied using potentiodynamic measurements, electrochemical impedance spectroscopy (EIS) and X-ray photoelectron spectroscopy (XPS). The addition of benzotriazole affects the dissolution of the m...

The activation of 8-quinolinethiosulfonates by zinc chloride promotes the usually difficult to achieve C3-alkylsulfenylation indoles at room temperature under aerobic conditions. This strategy is compatible with substrates containing various functional groups.
