Zeiss EVO-50XVP Environmental Scanning Electron Microscope (ESEM)
This is an extended pressure range SEM with a graphical user interface and digital image storage and processing. It has both a secondary electron (SE) detector and a four-quadrant backscattered electron detector (4Q-BSD). Electron acceleration voltages of 0.2 kV to 30 kV are selectable. The ultimate resolution is 3 nm. This instrument has a large multi-ported specimen chamber with a 5-axis motorized sample stage. The vacuum system uses an oil-free turbomolecular pump. In the extended variable pressure (XVP) mode, pressure from 1 - 750 Pa can be selected. The specimen atmosphere can be either air or water. Integrated with the Zeiss ESEM is an EDAX Genesis 2000 energy dispersive spectroscopy (EDS) system. This x-ray microanalysis system can detect all elements with atomic number greater than or equal to 5 and has software for calculating sample composition as well as for elemental mapping and compositional line scans.

Hitachi H-7600 Transmission Electron Microscope (TEM)
This TEM has an auto-focus capability with computer-controlled microscope operation (Windows R2000 OS3). Accelerating voltages of 40 kV to 120 kV are selectable. The ultimate resolution is 0.2 nm (lattice image). Samples are mounted on a 3 mm diameter specimen grid. This instrument has an AMT digital CCD system with a bottom-mount camera for acquisition of high-quality digital sample images.

Hitachi S-4800 High Resolution Scanning Electron Microscope (HRSEM)
This instrument uses a cold field emission electron source and can achieve an ultimate resolution of 1.0 nm at 15 kV and 2.0 nm at 1 kV. Accelerating voltages of 0.5 kV to 30 kV can be selected. This instrument has two secondary electron detectors. Operation and image-display are computer-controlled (Windows XP) with image-processing software also included. BMP, TIFF and JPEG image formats can be selected. The vacuum system includes 3 sets of ion pumps on the electron beam column and a turbomolecular pump on the sample chamber.

Oxford Diffraction Xcalibur 3 x-ray diffractometer (XRD)
This is a fully-enclosed single crystal XRD system. It has a Mo/Cu x-ray source with a Sapphire3 CCD detector. The instrument is computer-controlled with CrysAlisTM software for data analysis. Samples can be cooled to temperatures between 90 and 300 K with the Cryojet nitrogen jet cold unit.
Renishaw inVia Reflex Micro-Raman
The Renishaw inVia Reflex Micro-Raman is equipped with two laser excitation sources: a near infrared diode laser source (300mW) with an excitation wavelength of 785nm and an Argon ion laser source (25mW) with an excitation wavelength of 514nm. The laser spot size can be varied from 1 Ám to 300 Ám. Spectra can be obtained using a variety of acquisition modes such as single point scan, line mapping and area mapping. The confocal capabilities of the instrument allow depth profiling with 2.5 Ám resolution. The white light image montaging feature allows for large-area images of the sample surface to be captured, which can then be overlaid and compared with Raman spectral data maps of the same region. The instrument is designed for one-click switching between laser sources, with computer-controlled reconfiguration and optimization. Calibration is also automatic, using an internal reference sample.

Veeco Dektak 6M Surface Profiler
The Dektak 6M Surface Profiler is an instrument which measures topographical properties such as roughness, step height, and waviness. The system is equipped with two interchangeable, diamond-tip styli, with diameters of 12.5 Ám and 2.5 Ám. Resolution is accurate down to the angstrom scale. The instrument is capable of making measurements ranging from 50 Ám to 30 mm horizontally and from 5 nm to 262 Ám vertically. Data collection also features an automated mode in which up to 10,000 different scan routines can be run sequentially.

Leica EM UC6 Ultramicrotome with FC6 Attachment
The Leica UC6 with FC6 attachment is the new standard in ultramictoromy. This instrument can perform nanometer sectioning of biological and materials specimens at both ambient and cryogenic temperatures. The main function of this instrument is to prepare specimens for TEM analysis of internal details and microstructure. The knife stage is fully motorized, illumination of the sample is provided by three independent LEDs, and menus for set-up are available via a touchscreen display.
