New TEM Instruments Open for User Training in the Irvine Materials Research Institute (IMRI)

JEOL JEM-2100F Cryo-TEM and JEM-2800 S/TEM and TESCAN GAIA-3 XMH are available

Dear Colleagues:         I am pleased to announce that two TEMs (JEOL JEM-2100F Cryo-TEM and JEM-2800 S/TEM) and a dual beam focused ion beam system (TESCAN GAIA-3 XMH) in UC Irvine's Materials Research Institute (IMRI) are fully installed and now available for user training. IMRI is a newly established interdisciplinary organization under the Office of Research at the University of California, Irvine. Funded through a campus initiative to build a state-of-the-art materials characterization facility at UCI, IMRI purchased five major instruments, four transmission electron microscopes (TEMs) and one dual-beam focused ion beam (FIB) system for materials characterization. The instruments that are available for users include:

1.     JEOL JEM-2100F Cryo-TEM.  This 80-200 kV TEM is equipped with a field emission gun, a cryo stage, and a newly-introduced Gatan CCD camera (OneView) for the study of biological specimen at room and liquid nitrogen temperatures. The cryo TEM is suitable for observation of frozen hydrated specimens such as single proteins or two-dimensional crystals of membrane proteins.  

2.     JEOL JEM-2800 S/TEM. This high-throughput 100-200 kV Schottky field emission TEM will serve as a workhorse for structural/chemical analysis of materials. It features high resolution imaging in TEM, STEM, HAADF, ABF, and secondary electron (SE) modes (analytical high-resolution pole piece), ultrasensitive elemental mapping with large angle EDS, and the Gatan OneView IS camera for imaging and in-situ observations at 320 fps.  

3.     TESCAN GAIA-3 XMH integrated focused ion beam-FESEM. The GAIA-3 XMH FIB-SEM is TESCAN’s high-end flagship dualbeam instrument. It has a unique three-lens electron optical design capable of dedicated modes for extreme high-resolution imaging (magnetic immersion mode), enhanced depth of focus, undistorted ultra-low magnification imaging, live 3D stereo imaging, and TEM specimen preparation.  

In addition, the state-of-the-art aberration-corrected TEM (JEOL Grand ARM) has also been installed and is under the final tuning, which is expected to be available for user training in May. The unique NION’s ultra resolution scanning TEM (UltraSTEM HERMES200) has arrived and its installation will be completed by this summer 2017. All these instruments, with their powerful and unique features, will enable researchers to explore the atomic scale structure, chemical bonding, electronic properties, and dynamic behavior of various materials and biological specimens with the most advanced tools available today.

IMRI facilities are professionally staffed with open-access, user-friendly services. IMRI’s technical staff will train users and provide technical and scientific assistance. To sign up for training and to learn more about the detailed functionalities of these instruments, please visit our website:
