Dedicated to materials characterization, assays, and sample processing, the UC San Diego MRSEC-MCF is a user and service facility associated with the UC San Diego Materials Research Science and Engineering Center, funded by the National Science Foundation.  We are a member of the Materials Research Facilities Network, a nationwide partnership of Shared Experimental Facilities supported by the National Science Foundation’s Materials Research Science and Engineering Centers (MRSECs).

Location: We are located on the Main Campus of the University of California, San Diego

Facility offices: Pacific Hall, room 4140
Instrumentation is housed in the MRSEC facilities rooms on the 4th floor of Pacific Hall. Some instruments are housed in other locations. See "Details and rates" sections below for the location of each individual instrument.

Access to the equipment in the facility operates under three modalities:

(1) samples can be submitted for analysis by the facility staff (Consultation-non-training fee is applied in addition to instrument usage fee)
(2) user trainees can run samples under the guidance of facility staff (Consultation-Training fee is applied in addition to instrument usage fee)
(3) trained users can sign up for the instrument and run their own samples (instrument usage fee only).

For modality (1), samples from third parties are received and returned under a material transfer agreement (contact the Facility Manager). For modality (3), users must first be trained and checked out on an instrument by the facility staff (modality 2). Thus there is an additional charge if a staff member is involved in either running of samples or training of a user. Alternatively, the UC San Diego MRSEC RIMSE program held each summer provides an immersive introduction and training on most of the available instrumentation in this facility. Additional facilities in support of materials fabrication and characterization (and nanotechnology in particular) are available in UCSD's San Diego Nanotechnology Infrastructure (SDNI).

Porosimetry-Gas Sorption Analyzer (BET)

Anton Paar™ Quantachrome autosorbIQ automated gas sorption analyzer for measurement of chemisorption (hydrogen, methane, other reactive gases) and physisorption (nitrogen) processes.  The physisorption mode allows acquisition of data to determine surface area (via BET analysis of the isotherm), average pore size (via BJH or DFT isotherm models), and pore volume (via BJH or DFT isotherm models) on non-porous, mesoporous, and microporous materials. Featuring an extended range physisorption and chemisorption pressure transducer, system is capable of determining specific surface areas below 0.01 m2/g, active areas, pore volumes, and pore size distributions down to 0.35 nm in solid porous samples. Unit has 4 degas and 3 analysis ports for physisorption measurements on multiple samples simultaneously. Note sample degas and isotherm acquisition can require several hours of instrument time per run.  Mesopore samples usually require ~4hrs total; micropore samples generally require longer degas times and so can require up to 18h of analysis time. The mass of sample needed for analysis depends on its surface area; recommended total surface area for a surface area measurement is 2 m2 and for a pore size measurement it is 10 m2.  So for example if your sample has a specific surface area of 200 m2/g, it will require ~50 mg of material for a good analysis. The facility also maintains the older and slower Micromeritics™ ASAP 2020 gas adsorption/surface area measurement apparatus.
