Located in the basement of the Structure and Materials Engineering building at UCSD, this center contains an array of equipment and instruments covering a broad spectrum of materials characterization, synthesis, and testing capabilities which include:

  • Differential Scanning Calorimetry (DSC):  This is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. It features the fastest controlled heating and cooling rates, fastest equilibration for isothermal analysis, and calibration constancy.
  • Thermogravimetric/Differential Thermal Analysis (TG-DTA): This provides simultaneous measurements of the thermogravimetric (TGA) and differential thermal analysis (DTA) of materials.The instrument uses a dual balance beam design, which provides very stable TGA measurements and allows for the determination of the DTA response of the sample. The DTA signal is obtained with the incorporation of a thermocouple directly under the sample and reference measurement platforms.
  • Fourier Transform Infrared Spectroscopy (FT-IR) : This is a technique which is used to obtain an infrared spectrum of absorption, emission, photoconductivity or Raman scattering of a solid, liquid or gas. It is capable of data collection over a wavenumber ranged of 350 – 8300 cm-1.
  • Ultraviolet-Visible-Near Infrared Spectroscopy (UV-VIS-NIR):  This provides ultra-high UV/Vis/NIR performance for wavelengths up to 3300 nm with extreme sensitivity in the NIR region (800-2500 nm) and higher energy throughput. For applications such as highly reflective and anti-reflective coatings, all types of glass from clear to highly absorbing safety glass, optical filters of all types from the deep UV through the NIR and many more applications requiring the best photo-dynamic range and the widest possible sampling capability.
  • Raman Spectroscopy (RAMAN): This is a spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes in a system. Excitation source is 350 mW near infrared 785 nm laser; delivering100 mW at the sample. This instrument has a spectral range  of 95 – 3500 cm-1 Raman shift.
  • XRD system: It is use to analyze the phases of the material, composition, and some macroscopic information like crystallite size. Initial assessment of the material is usually done on this equipment.
  • Scanning Transmission Electron Microscopy (STEM) with Energy-Dispersive X-ray spectroscopy (EDX): STEM is distinguished from conventional transmission electron microscopes (CTEM) by focusing the electron beam into a narrow spot which is scanned over the sample in a raster.
  • ICP – Optical Emission Spectrometer from Perkin Elmer, model 3700 Optical Emission Plasma Spectrometer with AS90 Autosampler, is capable of axial or radial emission measurements. This instrument is used for a wide range of minor, major and trace elements determinations, and has a resolution of 0.001 nm, spectral range between 200 – 782 nm, and can measure sample concentrations from 1-1000ppb
  • Spark Plasma Sintering (SPS) from Thermal Technology LLC is used to process powder material into a dense sample. In contrast to conventional hot-pressing which heat samples by contact or radiative heating, the SPS can rapidly heat the sample via Joules heating, reaching temperatures of 2000C in minutes. Relative sample densities upwards of 95% can be achieved in a fraction of the time compared to convention pressure-heating techniques.
