SURF: Announcements of Opportunity
Below are Announcements of Opportunity posted by Caltech faculty and JPL technical staff for the SURF program. Additional AOs for the Amgen Scholars program can be found here.
Specific GROWTH projects being offerred for summer 2017 can be found here.
Students pursuing opportunities at JPL must be U.S. citizens or U.S. permanent residents.
Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor.
Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions! Remember: This is just one way that you can go about identifying a suitable project and/or mentor.
Announcements for external summer programs are listed here.
|Project:||Supercritical CO2 Organic Extraction Efficiency Study|
|Disciplines:||Chemistry/Chemical Engineering, Instrument Development|
|Mentor URL:||https://science.jpl.nasa.gov/people/Henderson/ (opens in new window)|
|Background:||With future in situ missions to Ocean Worlds now within reach, new instrumentation technologies are needed for accurate analysis of biomarkers and chiral species (potential indicators of life) from complex or unknown matrix materials. We are currently building a new instrument that combines our prior work in supercritical CO2 extraction with chromatography. This will enable us to extract and separate a wide variety of organics, including chiral species, from complex sample materials. The goal of this project is to extract, separate, and detect biomolecules from complex materials, including mixed ice/regolith (soil) and seawater samples. Successful demonstration of extraction and separation of biomolecules with this instrument will pave the way for future development of this technology for missions to icy worlds such as Europa.|
|Description:||The SURF fellow will conduct an analytical survey of biomolecule extraction efficiencies using our supercritical CO2 extraction system coupled with various analytical tools. Soil samples in either solid or aqueous form will be doped with known biomolecules and then extractions will be conducted at various temperature and co-solvent concentrations to determine the recovery yields.|
