W. M. Keck Imaging Facility

Go to Department of Mechanical Engineering website >

Through a generous grant from the W. M. Keck Foundation, we have recently acquired a state-of-the-art facility for electron microscopy. The facility consists of two transmission electron microscopes (TEMs), a new JEOL 2010F ultra-high resolution field emission TEM, and a refurbished JEOL 2000FX analytical TEM.
The JEOL FasTEM 2010F provides lattice imaging with a point resolution of 0.19 nm and an extended information limit near 0.10 nm. This instrument has many peripheral devices to enhance analysis, including scanning capability (STEM) with high-angle annular dark field detection, energy loss spectroscopy and imaging, and energy dispersive X-ray spectroscopy. In addition, this instrument is internet-ready, allowing for collaborative access and remote control of the instrument.
The JEOL 2000FX is used as a general purpose TEM and as a teaching instrument. It has a point resolution of 0.29 nm and is equipped with STEM capability and energy dispersive X-ray spectroscopy.
These instruments are equipped with a variety of specimen holders, allowing studies at temperatures from 20 K to 1270 K, cryogenic transfer studies, and studies with very low X-ray background.
This facility also houses two scanning electron microscopes, a JEOL 840 SEM and a Philips PSEM 501.

The Fuel Cell Research Lab is equipped with three Arbin test stands for performance evaluation of PEM and DMFC fuel cells. Facilities are available for the fabrication of novel membranes, catalysts, catalyst supports, and gas diffusion layers.  Equipment is available for fuel cell component characterization including EIS, CV, ECSA.  SEM, TEM, XRD, XPS, ICP and DSC facilities are also available in associated labs. System level studies include microvisualization of water transport within operating fuel cells, a virtual fuel cell hybrid vehicle simulator, and a computational capability for the complete simulation of PEM fuel cells.
A thermochemical reactor for the renewable generation of hydrogen from concentrated sunlight, and an experimental setup for hydrogen storage using solid-state materials are available.

The piece of equipment shown here combines an electrochemical test cell with an ultra high vacuum (UHV) chamber in which researchers can analyze the surface of electrode materials using X-Ray Photoelectron Spectroscopy (XPS). 

Novel fuel cell catalysts are first synthesized and characterized in the UHV chamber before being brought into a side chamber that contains the electrochemical test cell.  Within the side chamber, studies on the activity and stability of the fuel cell catalyst are conducted in the presence of an inert gas.  After tests are made, the catalyst is inserted back into the main chamber where XPS surface analysis is conducted to see if the catalyst has degraded during the electrochemical tests.  This set-up is unique because it allows all experiments to be done without ever exposing the catalyst to air, which will normally alter a catalyst surface in between electrochemical and XPS measurements.

The nanomaterials for energy lab has multiple pieces of equipment for fabrication and characterization of ceramics, thin films, and other solid state electrochemical systems.  A suite of ceramic powder processing tools (scale, ball mill, sieves, hotplate) is available to fabricate bulk materials samples.  Various tube furnaces allow high temperature processing and characterization in a controlled environment.  A custom built PVD Products sputtering system creates thin film ceramics, metals, polymers, and composites.  In addition to DC electrical characterization instruments, a Novocontrol Alpha-A impedance analyzer is capable of measuring high impedance (up to 10 TΩ) samples from 3 MHz to 3 μHz.

This illuminated electrochemical test cell is used to test various electrodes for use in photoelectrochemical cells (PECs).  A PEC is a special type of solar cell, which is capable of directly converting sunlight into chemical or electrical energy.

As suggested by its name, the operating principles behind PECs share much in common with both solar cells and fuel cells.  In the right side of the picture above, a polysulfide-based PEC with its characteristic orange color is illuminated from the left by a lamp.  The front of the test cell is made of a quartz lens, which allows for the light to pass into the cell where it is converted to electricity by a semiconducting photoelectrode and metallic counterelectrode.
