Undergraduate Research: Plasma Sterilization
This report details the test results and brief summary of my experiences participating in undergraduate research as a member of the Applied Physics Research Group, led by Dr. Subrata Roy, studying the sterilizing effects of Dielectric Barrier Discharge Plasma on yeast. This undergraduate research project provided a valuable vehicle for experiencing advanced research methodology and data collect...
متن کاملPlasma sterilization . Methods and mechanisms *
Utilizing a plasma to achieve sterilization is a possible alternative to conventional sterilization means as far as sterilization of heat-sensitive materials and innocuity of sterilizing agents are concerned. A major issue of plasma sterilization is the respective roles of ultraviolet (UV) photons and reactive species such as atomic and molecular radicals. At reduced gas pressure (≤10 torr) and...
متن کاملDensity Functional Theory Studies on the Addition and Abstraction Reactions of OH Radical with Benzoate Anion
The addition and abstraction reactions of OH radical with benzoate anion are investigated by density functional theory calculations that include solvent effects using UB3LYP, UCAM-B3LYP, UmPW1PW91 and UM06-2X functionals with the 6-311++G(2d,2p) basis set. Geometry optimizations of the reactants, products and transition state species are performed for the possible reaction paths. For the additi...
متن کاملQuantification of hydroxycarbonyls from OH-isoprene reactions.
Hydroxycarbonyls arising from OH-initiated reactions of isoprene have been quantified by the technique of a flow reactor coupled to proton-transfer reaction mass spectrometry (PTR-MS) detection. The yields of C5- and C4-hydroxycarbonyls are (19.3 +/- 6.1)% and (3.3 +/- 1.6)%, respectively, measured at a flow tube pressure of about 100 Torr and at a temperature of 298 +/- 2 K. A yield of (8.4 +/...
متن کاملMeasurement of OH Radicals in Aqueous Solution Produced by Atmospheric-pressure LF Plasma Jet
The chemical effects of the plasma are largely related to the formation of reactive oxygen species (ROS). OH radical is one of the ROS and has a strong oxidation potential. In this study, low frequency (LF) plasma jet was generated at atmospheric-pressure and irradiated onto the surface of aqueous solution. A portion of the OH radicals dissolved into aqueous solution was measured by chemical do...
