Engineering Core Facility
Mission
The goal of the Engineering Core Facility (ECF) is to support investigators in pursuit of their studies to answer specific research questions. This facility is equipped with a Transmission Electron Microscope (TEM), a Scanning Electron Microscope (SEM), an Atomic force microscope (AFM) and a Dynamic Mechanical Analyzer (DMA). ECF provides advice, technical services, training and use of facilities to investigators. ECF is available to all 小蝌蚪APP personnel, as well as outside institutions and industrial users. The facility is supported, in part, by user fees to cover supplies, instrument time, and a technologist鈥檚 time to carry out any part of the project. A fee schedule is available on request.

The sputter coater is used in preparing samples for examination under the transmission electron microscope by coating them with a thin metallic conductive layer.
The ultramicrotome is used to prepare extremely thin samples for examination under the transmission electron microscope.
The critical point dryer is used to dry samples for microscope examination by evaporation through the critical point so that there are no surface tension issues.
