Private Donations

Monetary donations from private individuals and companies have been invaluable for the group because they make it possible to purchase items than cannot be acquired with federal grants, such as computers for the graduate student offices. Such donations can also give the students an opportunity to travel to conferences, buy books, pay for their membership in professional societies, etc.

If you are interested in supporting our research you can do this by sending a check payable to UC Regents to the dean of the School of Physical Sciences (the address is given below). Be sure to indicate in your cover letter that the check is meant for the Aerosol Research Group fund 445954-56114. You will get a formal letter from the dean acknowledging your donation. You can also donate money on-line (select School of Physical Sciences, Department of Chemistry Support).

Equipment Donations

We are constantly looking for donations of used or new instruments both for research purposes and also for serving the needs of undergraduate education in the UCI Chemistry Department. If you have research equipment in working condition that you no longer need consider giving it a second life. We are especially interested in the following items:

  • UV/Vis and IR optical instruments such as FTIR spectrometers and spectrophotometers, and accessories for such instruments
  • GC, GCMS, and HPLC chromatographic equipment and accessories
  • Aerosol particle instruments such as particle counters, particle sizers, particle generators, and particle samplers.
  • Research grade lasers and optics
  • Gas monitors for ozone, CO, CO2, NOx, NOy, SO2, and other atmospherically relevant species.
  • Gas handling equipment including mass flow controllers, flow meters, pressure sensors, zero-air generators, ozone generators, etc.
  • Mass-spectrometers
  • Various laboratory instruments and tools such as vacuum pumps, compressors, microscopes, balances, ovens, dewars, cryostats, environmental chambers, deep freezers, leak testers, etc.
  • Various electronics including power supplies, function generators, oscilloscopes, amplifiers, fillters, delay generators, lock-in amplifiers, integrators, counters, etc.

If you have equipment to donate please e-mail Prof. Sergey Nizkorodov at or call him at 949-824-1262.
