This facility consists of a PHI Model 600 scanning Auger microprobe (SAM). Recently, the instrument was upgraded with a modern PC based computer, new controlling electronic modules, and new software that improves our capabilities to acquire, process, and transmit the data. In early 2003, we plan another software upgrade that will increase the number of acquisition points, from 40 to 1000, in the Multiplex mode. This mode allows acquisition of semi-quantitative elemental compositions at specific points on the sample surface. This will be especially useful for our study on GBs segregation, where a wide range of GBs have to be chemically analyzed on fracture surfaces.

Chapel Hill Analytical and Nanofabrication Laboratory (CHANL) houses facilities for materials characterization and a versatile suite of instrumentation for micro and nanofabrication.

The lab provides professional consultation on problems regarding electronics design and operation. It also provides fee-based repair and equipment construction services to MRSEC members. In the recent past, it has designed and constructed specialized circuitry for laser power and timing stabilization, computer interfaces for electron energy spectrometers, and high-frequency quadrature signal demodulators. In addition, the lab maintains a pool of electronic measurement and test equipment that can be signed out by MRSEC members.

Freeze-fracture transmission electron microscopy (FFTEM) is a powerful technique for imaging the nanometer-scale structure of soft condensed matter, revealing features as small as a single smectic liquid crystal layer (~ 3 nm). We use FFTEM to study the bulk and interfacial structure of equilibrium and non-equilibrium states of liquid crystals and nanocolloids.

Analytical techniques available include Auger spectroscopy, X-ray photoelectron spectroscopy, atomic force microscopy, and several kinds of thermal analysis. A wide array of spectrophotometric techniques, including UV-visible-near IR spectrophotometry, Fourier transform infrared spectroscopy, Raman spectroscopy and fluorimetry are also available.

The Mechanical Testing Facility enables investigators to create novel materials and structures through crystal growth, hot pressing, vacuum casting, diffusion bonding, and cold iso-static pressing. Once created, materials may be shaped by conventional machining, wire EDM, and specialty surfacing equipment. The mechanical properties of the material may be characterized over a wide range of temperatures, atmospheres, loading rates, and testing regimes. The facility is staffed by a senior research engineer and two senior technical assistants.

This facility is maintained in Prof. Ozdoganlar's laboratory and used for a variety of MRSEC experiments, including the preparation of specimens for FIB studies. The main equipment in this laboratory is 1) A three-axis miniature machine tool for micromilling, microdrilling, and microgrinding applications, 2) A micro-capable laser Doppler vibrometer system for experimentation on dynamics of micro- and nano-scale structures, 3) Planing equipment for micro-scale material removal (in development), and 4) Bridgman furnace for fabricating single-crystal workpieces (in development).

All instruments are available for responsible users to test their own samples. Training is offered quarterly for the more complex instruments and users may self train on the other instruments any time. There are specific insurance and liability requirements for off-campus facility users. They are described at this link: Non-UCSB Use of MRL Facilities

All people working in the TEMPO lab are required to follow good practice and to have already attended the UCSB EH&S Laboratory Safety Training.

The High-Field NMR Facility at the University of Massachusetts Amherst is an interdepartmental facility, open to researchers of the Five Colleges Consortium (UMass Amherst, Smith, Mt. Holyoke, Amherst and Hampshire Colleges) and surrounding industries. It supports research programs of twenty groups in the areas of chemical synthesis, polymer chemistry, materials science, and natural products. The facility oversees five NMR spectrometers. Two of them (DPX300 and Avance400) are public-access spectrometers for the research needs of 200 users and the teaching needs of graduate and undergraduate students from all science and engineering majors. Three additional spectrometers are available for advanced applications. The Avance600 spectrometer is equipped with a cryoprobe and capable of triple resonance and gradient experiments, while the DSX300 and Infinity300 are wide bore solid-state spectrometers which are equipped for triple resonance, high-speed magic angle spinning, and wideline experiments. The spectrometers are Ethernet-linked to a number of Silicon Graphics and Windows computers for data analysis, computation, and manipulation of three-dimensional structures.
