Nonthermal atmospheric plasma (NTAP) can be applied to living tissues and cells as a novel technology for cancer therapy. The authors report on a NTAP argon solution generated in deionized (DI) water for treating human gastric cancer cells (NCI-N87). Our findings show that the plasma generated in DI water with 30-min duration has the strongest effect on apoptosis in precultured human gastric ca...

Background: In the present study, histopathological effects of chronic exposure to sodium arsenate in drinkable water were studied on a quantity of organs of rat. Methods: Rats were divided into two groups, group I served as control group, were main-tained on deionized drinkable water for 2 months, and group II the study group were given 60 g/ml of sodium arsenate in deionized drinkable wa...

Objectives. Antimicrobial activities of non-thermal atmospheric plasma-treated liquids on various bacterial and fungal strains in their planktonic and biofilm forms have been widely reported. Since most of the plasmatreated liquids are water based, they might be washed off certain surfaces and they cannot be applied for the infections of respiratory tract. In the present study we have tested an...

Drinking water treatment facilities remove impurities from raw water sources using various chemicals. The by-product produced from the purification process is called water treatment residuals (WTR). If WTR contain residual chemicals from the purification process, soluble elements may be released potentially causing chemical imbalances in soil and groundwater systems. The study objectives were t...

Properties of GaN surfaces etched by bias-assisted photoenhanced electrochemical (PEC) oxidation in deionized water and subsequent removal of the oxidized material are investigated using Schottky diodes fabricated on etched surfaces. It is demonstrated that with a short anneal at 700 C after removal of the oxide, it is possible to obtain a low damage surface with near ideal breakdown and capaci...
