Dielectric barrier discharge plasma has been known to inactivate many different microorganisms on surfaces when treatment times are on the order of seconds or minutes in duration. In this paper, a unique plasma air cleaning facility was created which combines a dielectric barrier grating discharge (DBGD) with a filterless laboratory-scale ventilation system(More)
BACKGROUND Epidermal growth factor receptor (EGFR) mutation plays a vital role in the prognosis of patients with lung cancer. However, there is a dearth of studies on EGFR mutation in Indian population. In this retrospective study conducted at a network of tertiary cancer care centers across India, we evaluated the proportion of EGFR mutation in patients(More)
Summary form only given. In the semiconductor manufacturing industry, fluorocarbon-based plasmas are increasingly being replaced by NF<sub>3</sub> plasmas for cleaning of CVD chambers. The clear advantages in doing so include faster clean times, reduced chamber damage and substantially lower emissions of gases having high global warming potentials (GWPs).(More)
Summary form only given. The stability and uniformity of a radio-frequency (RF) discharge is limited by a critical power density. Beyond this critical power density, instability occurs in the form of with physical changes in the plasma (such as contraction due to arcing). Levitsky identified and studied the two glow modes, alpha and gamma, of operation of(More)
