Non-Thermal Plasma Technic for Air Pollution Control

Improving the pollutant removal efficiency of packed-bed plasma reactors incorporating ferroelectric components

“…One of the most common applications of dielectric barrier discharge (DBD) plasmas is the decomposition removal of gaseous pollutants [1][2][3][4]. A great number of works have been published about the use of these plasma discharges for the removal of volatile organic compounds (VOCs) present in the air as a result of different industrial and in-door activities [5][6][7][8][9][10][11][12][13][14][15][16][17][18]. However, although a large variety of reactor set-ups and working conditions have been proposed to maximize the efficiency of these processes [19][20][21][22][23], most studies have addressed the kinetics of the removal process and paid little attention to the analysis of the plasma, the electrical operation parameters or the effect of the reactor configuration.…”

Ambient Temperature Hydrocarbon Selective Catalytic Reduction of NOx Using Atmospheric Pressure Nonthermal Plasma Activation of a Ag/Al2O3 Catalyst

“…In many cases, the NTP is placed upstream of the catalyst bed [17,25,26] and activates the gas prior to contacting with the surface of the catalyst. For example, Rappé et al [26] reported ~80% reduction of NOx in a simulated lean exhaust over a Ba/zeolite Y and Ag/ γ-alumina catalytic system at 200 o C with the plasma upstream of the catalyst bed.…”

Atmospheric Pressure Plasma Surface Treatment of Polymers and Influence on Cell Cultivation

“…Moreover, this stage depends on the biomaterial surface’s properties, biophysical environment, and biological molecules. The last stage determines the life of the implanted biomaterials which can last several decades [ 84 , 85 , 86 ]. Figure 8 demonstrate the cell-biomaterial interaction stages.…”
