Stable aqueous dispersions of carbon black (CB) nanoparticles were prepared by developing a generic bilayer approach to the CB phase-transfer method using commercial Avanel as a surfactant. CB was oxidized using ammonium persulfate, and dodecylamine (DDA) was grafted onto this carbon core using N,N-dicyclohexylcarbodiimide as a coupling agent. The covalent bond between CB and DDA was confirmed by...
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 and is used to treat concentrated bacterial...
Summary form only given. The best plasma discharge system for combustion applications should generate non-equilibrium plasma with high concentration of active species and intermediate temperatures, high enough to support chain propagation reaction. The non-equilibrium gliding arc (GA) aptly suits this application. However, to study and characterize GA plasma enhancement process we need to stabilize...
Summary form only given. Drexel Plasma Institute has several projects that exploit gliding arc as a source of atmospheric pressure transitional plasma. Transitional plasma or transplasma has parameters in the range between cold and thermal plasmas. Transplasma offers distinct advantages in some processes. We are using transplasma generated by gliding arc (GA) in different systems for the following...
Summary form only given. Drexel Plasma Institute has several plasma systems for air cleaning and sterilization. High-volume pulsed corona discharge system has been developed as a core of the mobile pilot plant to demonstrate promising technology for treatment of high volume low concentration (HVLC) industrial ventilation streams contaminated by volatile organic compounds (VOC). Gas phase organic compounds...
