Surface Functionalization and Passivation of Aerosolized Silicon Nanoparticles
For nanoparticles to be components of new materials and devices, methods must be developed to control their surface properties. Much of the research has focused on solution-based chemical processing. However, solution-based methods have numerous disadvantages from both engineering and environmental perspectives. In my seminar, I will describe a new and widely applicable method for functionalizing and passivating the surfaces of
aerosolized nanoparticles. In one set of experiments, organic monolayers derived from amines, alkenes, and alkynes were deposited onto crystalline silicon nanoparticles by spontaneous adsorption from the gas phase. In another set of experiments, multilayer films of group IV metal oxides, including zirconium dioxide, were deposited on silicon via chemical vapor deposition. The results are important because they describe a new approach for manipulating and controlling interfacial properties in nanoparticles that have materials applications. More generally, the results are among the first kinetic and mechanistic studies of aerosolized silicon nanoparticle reactivity.
Journal Club Meets This Week
Journal Club meets this Thursday at noon in Mudd 171 to discuss a paper relating to this week’s seminar. For information about what to read beforehand, go to the following: http://apps.carleton.edu/curricular/chem/events/?category=171005&no_search=1.

Summer Internship at Monsanto
The Protein Sciences team within the Agronomic Traits Program at Monsanto has an immediate opening for a summer intern. Possible responsibilities include assisting a senior scientist in cloning, expression, purification, and bioassay of insecticidal bacterial protein toxins. Successful applicants are expected to have familiarity with basic biochemistry and molecular biology (lecture courses are sufficient). Laboratory experience is an added plus.
To find out about applying for the position, please contact Sonya J. Franklin (’89 Carleton chemistry major), Director of Protein Sciences, Monsanto: sonya.j.franklin@monsanto.com.
Chemistry Picnic
Brats, Burgers, and Big Woods!
Don't Forget to Sign Up by Friday, May 18
Hey, it’s time to think about spring, barbecue, waterfalls, hiking, potato salad, frisbee, and brats! The chemistry picnic will be on Friday afternoon, May 25, at Nerstrand Big Woods State Park (the usual spot). The picnic will start about 5:00 p.m. Please sign up for the picnic by Friday, May 18, and include your student ID#, your grilling preference (carnivore or herbivore), and whether or not you need transportation. The sign-up sheet is across from Dani Kohen’s office, posted on the window of the Mudd 169 computer room. The chemistry faculty and staff will also supply food and treats, and the RING is in charge of entertainment. A bus is scheduled to leave the Mudd parking lot at First and Nevada Streets at 4:30 p.m. (after Honors Convocation) to transport any of you who don't want to drive or prefer to save fossil fuels using communal transportation. The bus will return to campus somewhere between 7:30 and 8:00 p.m. We especially welcome new chemistry majors!
