The goals of the MMRC are to synthesize, from the molecular level, materials and combinations of materials with unique and desirable properties and to provide the Caltech community with routine access to state-of-the-art instrumentation for materials characterization. Current emphasis of the Research Center is on materials and devices useful in artificial photosynthesis and solar energy conversion, electroactive compounds, unique nonlinear optical materials, devices capable of detecting volatile organic chemicals, formation of self-assembled monolayers on surfaces, surface science methods to probe the chemistry of solids, and characterization of magnetic materials ranging from asteroids to nanomaterials.
In the area of characterization, the MMRC maintains and operates a variety of major instrumentation, including:
The Center also provides expertise in the following areas: solid materials characterization using modern UHV-based surface science techniques; scanning probe microscope used to characterize specimens from biological samples to novel electronic materials; electrochemical characterization of charge-transfer properties and reduction potentials of molecular species, sensor array technology, heterogeneous and homogenous electron-transfer reactions, characterization of nano-particles and protein size using light scattering. Four laboratories in the subbasement of the BI are devoted to the development of nanomaterials for artificial photosynthesis, solar conversion studies, chemical sensor fabrication, inorganic synthesis, and sample preparation. Facilities include vacuum lines, Schlenk inert atmosphere lines, inert atmosphere boxes, a GC-MS instrument, spin coating, UV-vis spectrophotometer, and visible photolysis facilities.
To use MMRC facilities, contact Bruce Brunschwig or the appropriate member of the MMRC staff (see MMRC web pages). All users will be trained and required to demonstrate proficiency using the MMRC instrument before being allowed to work with the instrument on their own. The MMRC provides free access to its instrumentation and expertise although, in the case of extended use, a financial arrangement covering the cost of materials may be necessary.
