Non-thermal Plasma Applications in Air Sterilization

Department:
MEM
Faculty supervisor:
Alexander Gutsol
Description of activities:
Our goal is to sterilize air which is contaminated
with viruses using a non-thermal plasma reactor. Non-thermal
plasma is created with a high voltage electrical energy
source and is comprised of charged species (electrons,
ions), active chemical species (radicals like ozone),
and ultraviolet radiation. We will use these active
species to kill various airborne microorganisms through
processes of oxidation and irreparable radiation damage
to intracellular DNA.
Student responsibilities:
The student chosen for this opportunity will be responsible
for operating and troubleshooting bioaerosol generation
and air sampling equipment. This will involve culturing
and assaying non-pathogenic microorganisms such as
viruses, bacteria, and bacterial spores. This is an
excellent learning opportunity for someone who seeks
to gain skills with handling & detecting microorganisms.
There will also be additional opportunities to participate
in the design of new non-thermal plasma reactors (no
experience is required). This is a voluntary position
and daily start times and work duration are flexible.
The Department of Materials Science and Engineering
has funding for
bright, hardworking undergraduate students to work
on specific research projects. Go to http://www.materials.drexel.edu/research/
and check out the on-going research in Materials Science
& Engineering and, when you have chosen the research
group(s) that most interests you, contact Judy at
judith.trachtman@coe.drexel.edu
to set up an interview with the pertinent faculty
member(s).
