A wide variety of analytical instruments and tools are available to members of the Schilke/McGuire lab and our collaborators. A semi-current list of useful resources follows. Please feel free to contact Dr. Schilke for more information or to get access to any of these instruments.
Instrumentation and Equipment
- Q-Sense E4 Quartz Crystal Microbalance with Dissipation (QCM-D) system
- MicroVacuum, Ltd. OWLS 210 Optical Waveguide Lightmode Spectroscopy system
- First Ten Angstroms FTA-T10 tensiometer, with ring and plate probes.
- Virtis 3.5L-DBT bench-scale lyophilizer with vacuum manifold.
- Thermo-Electron Genesys 6 scanning UV-Vis (190-1100nm) spectrophotometer with 6-cuvette turret and floppy drive.
- Plate Reader Information and Use
- Manual optical goniometer, for measuring contact angle of liquids on solids.
- Miscellaneous laboratory equipment (microcentrifuge, analytical balance, fume hood with argon and nitrogen gas, vacuum oven, Precision glassware oven, Harvard Apparatus PHD 2000 syringe pump (manualΔ and datasheetΔ), dual incubator).
Drs. Schilke and McGuire often collaborate with other members of the OSU community and outside of OSU. A number of instruments outside of our lab are thus available to our group, for research purposes. You need to arrange use of these instruments with their owners, who will often require some hands-on training before you can use them. Plan accordingly. Please be extra careful with equipment in other people's labs — we don't want to lose our access to these resources!
- There are two Brookhaven Instruments ZetaPals zeta potential/particle size instruments available to us:
Circular dichroism is used to measure changes in protein/peptide structure. There are a few instruments on campus, the most accessible of which is:
- Kerry McPhail (Pharmacy) in Oak Creek Building
Microscopy and Surface Visualization
Scanning Electron Microscope (SEM)
Fee-based electron microscopy services are available on-campus in the OSU Electron Microscope Facility. They have a Philips CM-12 scanning transmission electron microscope (STEM), a FEI Dual Beam field emission scanning electron microscope (FESEM), and a FEI environmental scanning electron microscope (ESEM).
SEM/TEM and other microscopy services are also available from Portland State University's Center for Electron Microscopy and Nanofabrication, and at University of Oregon's CAMCOR facility.
Atomic Force Microscopy (AFM)
We have access to several AFMs around campus, two of which are just around the corner.
Dr. Phil Watson in Chemistry (Gilbert 042) has a Digital Instruments Nanoscope. It is capable of imaging dry samples, or under fluid.
Dr. Ethan Minot has an Asylum Research AFM that can also image soft features under fluids.
Contact Dr. Watson or Dr. Minot directly for training and availability of these instruments.
The Linus Pauling Science Center houses the campus NMR facility (102 Gilbert Addition), with two 400MHz and a 700MHz Bruker spectrometer.
See Rodger Kohnert for training; Rat can assist with sample prep, instrument operation and 1H/13C spectrum interpretation. There is also a high-resolution (900 MHz) spectrometer available in Biochemistry/Biophysics.
- An ATR IR system is available in the basement of Gleeson Hall. Contact Dr. Alex Yokochi for more information.
- Transmission FT-IR instruments are available for student use in the Chemistry department teaching labs. Contact Christine Pastorek for more information. Note that scheduling time on these instruments is difficult because they are reserved for class/lab use during most of the week.
- Dr. Simonsen in Wood Science has an ATR instrument with a ZnSe crystal.
- Dr. McIntyre in Physics has an integrating sphere instrument (and other IR systems).
Thermal Characterization (DSC/TGA) & Contact Angle
- Dr. Rochefort's lab has a Differential Scanning Calorimeter (DSC) and a Thermogravimetric Analyzer (TGA). These instruments can be used by members of our lab after training. Contact Skip for training.
- We have a manual contact angle goniometer in the Schilke/McGuire lab.
- The Rochefort lab also offers a First Ten Angstroms device (model?) that computes the contact angle of liquids on surfaces. See Staci Van Norman for more information.
- Melting point apparatus is available in the Chemistry teaching labs. Contact Christine Pastorek.
Radiation Center (γ-irradiation)
The OSU Radiation Center offers γ-irradiation services for a low cost. Currently, the contact for this process is Scott Menn (Scott.Menn@oregonstate.edu). Doses of 0.5 Mrad or less are $95/run (total price for all samples that can be packed into the irradiation chamber).
Rapid Prototyping / 3D Printing
- The COE has purchased a Dimension Printing 3D printer. To submit parts to be printed, go to http://eecs.oregonstate.edu/education/3dprinter/. This device can build up complex shapes from ABS layers 245µm thick. The cost is extremely reasonable, too:
- For internal use (account codes) the rate is $5.50 per cubic inch, with a $5 setup fee.
- For external use, or people paying by credit card, it is $16 per inch3, with a $10 setup fee.
- There is an ancient impulse sealer (for sealing plastic bags) in ChemStores (Rm. C). Ask Dan if you want to use it. An 8-second "on" pulse works well with polyethylene zipper bags. Press hard for best results.
- Nitrogen Adsorption (BET) Surface Area
Dr. Rorrer has a BET system in his lab (Gleeson 302), but it is currently not working.
Contact him if you would like to help get it running again.
- Electronic parts, wire, plugs and connectors, LEDs, etc. can be purchased from the IEEE Electronics Store in the basement of Dearborn Hall. This is a student volunteer-run store, so expect a strange schedule.
