COLLABORATING
FACILITIES
Affiliated
facilities are not offered through the CNMS proposal and review
process but users may make independent arrangements to use these
facilities through establishing a research collaboration with
the ORNL scientists who are responsible for them. Often, a
user may
first recognize only after a project has begun that one of these
facilities would be useful and arrangements can be discussed
at that time. These facilities may be cited in a user
proposal only if the proposal writer first obtains written
consent from
the ORNL
collaborator and attaches a copy with the proposal submission.
Users may contact the CNMS staff member at any time for help in identifying
the appropriate collaborator for one of these facilities.
PLD of Catalyst Films - Continuous Compositional Spread
Optimazation
(Affiliated with Optical-Nanostructure Interactions)
Continuous compositional-spread (CCS) for catalyst optimization:
pulsed-laser deposition of metallic films with orthogonally
overlapping “wedge”-shaped
thickness profiles.
PLD of Oxide Thin Films - Continuous Compositional Spread
Discovery
(Affiliated with Optical-Nanostructure Interactions)
Continuous compositional-spread (CCS) for oxide film search
and discovery: pulsed-laser deposition of complex oxide films
with laterally varying chemical composition
across (pseudo-)binary or (pseudo-)ternary phase diagrams, without requiring
a post-annealing process.
Temperature Gradient Pulsed Laser Deposition of Thin Films
(Affiliated with Optical-Nanostructure Interactions)
Temperature-gradient method for oxide film growth: simultaneous
pulsed-laser deposition onto multiple substrates at different
temperatures.
Electrical
Characterization (Affiliated with Optical-Nanostructure
Interactions)
- Resistance
as a function of temperature
- Capacitance
as a function of frequency, bias voltage,
and temperature
- Ferroelectric
hysteresis and fatigue
Catalysis
Reactors (Affiliated with Catalysis;
Contact-C.
Narula)
- High
pressure flow reactor, (up to 1500 psi and 600ºC). Reactor
is currently optimized for studies of oxidative dehydrogenation.
- Benchtop
flow reactor for studies of emission control catalysts. Reactor
is currently optimized for studies with simulated vehicle exhaust
and capable of lean/rich swings, for studies of NOx catalysts,
NOx traps and 3-way catalyst behavior.
- Ex-situ
reactor for treating samples for TEM studies. Reactor is currently
optimized for studies of effects of simulated vehicle exhaust upon
structure of catalysts.
