Dr. Elizabeth Wright
Dr. Elizabeth R. Wright is Assistant Professor in the Department of Pediatrics, Emory University School of Medicine. She is the Director of Robert P. Apkarian Integrated Electron Microscopy Core (RPAIEMC) at Emory University. She is also a Georgia Research Alliance Distinguished Investigator Director.
Dr. Wright collected the TEM data shown on bacterial samples using phase plates specifically designed for the JEOL TEM by Prof. Kuniaki Nagayama’s lab at the Okazaki Institute for Integrative Bioscience in Japan, the lab that developed the technology. She also collected data in the lab of Dr. Wah Chiu at the National Center for Macromolecular Imaging at Baylor College of Medicine in Texas, a center for excellence in cryo-electron microscopy.
Emory University studies a broad range of biological and soft materials samples such as: infectious viruses; pathogenic and nonpathogenic bacteria; mammalian tissues; self-assembled peptide matrices; and nanoprobes.
For these applications, the JEOL model JEM-2200FS TEM with its in-column energy filter and thin film/electro-static phase plate technology is the showpiece of the expanded EM laboratory.

Schepens Eye Research Institute
Schepens Eye Research Institute in Boston, Massachusetts is the largest free-standing eye research institute in the United States. Schepens is renowned for major breakthroughs in treatment of retinal disease, optic nerve regeneration, new cures for macular degeneration, diabetic retinopathy, glaucoma, other types of retinal and optic nerve degenerations and damage, dry eye, and eye tissue transplants.
Dr. Ilene Gipson is an Ocular Surface Scholar & Senior Scientist and, as one of Schepens’ more than 20 principal investigators, she also serves as Professor of Ophthalmology at Harvard Medical School. She and her staff associate, Ann Tisdale, have made mucus the focus of their investigation into dry eye disease in recent years. They have worked together for three decades studying the ocular surface of the eye and the role of mucins in its protection. They use the JEOL JSM-7401F, a previous model of one of our high resolution field emission SEMs, in their work.
We conducted an extensive interview with Dr. Gipson while on a tour of Schepens. Read more here in our REALab story.
National Institute for Advanced Industrial Science and Technology (AIST)
Dr. Kazu Suenega is a team leader at the National Institute for Advanced Industrial Science and Technology (AIST). He has published over 90 scientific papers and delivered more than 50 invited lectures over the past ten years. His papers have more than 3,000 citations. He has received several awards: the Honda Memorial Promotional prize (1997) and the Seto award (Japanese society of Microscopy 2005), and the Sir Martin Wood Prize in 2006.
At AIST, Dr. Suenega’s major research theme involves the atomic level characterization of individual molecules by means of electron microscopy and spectroscopy. His team used the JEOL JEM-2100F TEM with a Schottky-type field-emission gun equipped with aberration corrector to obtain the spectacular image of the metallofullerene peapod shown in this image from the paper “Visualizing and identifying single atoms using electron energy-loss spectroscopy with low accelerating voltage” published in Nature Chemistry in August 2009.
In recent groundbreaking work, Kazu Suenaga and Masanori Koshino have imaged and characterized the electronic properties of single atoms at the edge of graphene using a probe just 0.1nm in diameter to pinpoint single atoms. Operating at a low voltage of 60kV – below the threshold of thermal or knock on damage - produced high spatial resolution while leaving samples in tact. This is the first time specific spectral peaks have been obtained from specific atoms. Their findings on how these atoms bond with one another are published in Nature.
U.S. energy companies examine oil shale porosity with unique JEOL solutions
Energy companies have turned to JEOL for SEM, FIB, and cross section polishing solutions in recent years with the express purpose of examining oil shale samples.
Investigating the potential of oil shale deposits to produce economically viable alternative sources for oil and natural gas requires requires studying the porosity of well-prepared flat samples at both the macro and nano scale.
Shale is notoriously difficult to prepare for SEM by standard mechanical methods because it tends to crumble and the features are often obscured due to smearing. Oil shale is a fine-grained, sedimentary rock composed of flakes of clay minerals and tiny fragments of other minerals, especially quartz and calcite. Shale also has a complex network of soft veins of an organic substance, kerogen and accessory opaque minerals such as pyrite.
The JEOL cross section polisher slices and polishes the sliver of shale with an argon beam to yield undistorted, precise cross sections. Every detail can be clearly seen, allowing researchers to see the complex network of veins of kerogen in the sample. They can then make 3D reconstructions of the pore network by using a Serial Slicing and Sampling technique with the Multibeam focused ion beam (FIB) instrument.

SEM Technology Advances Energy Research.
Downing Lab, Lawrence Berkeley National Laboratory
Dr. Kenneth Downing’s lab at the U.S. Department of Energy Lawrence Berkeley National Laboratory made a major breakthrough for cancer research by solving the atomic level structure of tubulin, the protein responsible for cell division. The team of Eva Nogales, Sharon Wolf, and Kenneth Downing published the paper “Structure of the αβ tubulin dimer by electron crystallography” in Nature in January 1998.
Scientists had been seeking to understand tubulin since the 1950s. Better knowledge of how tubulin polymerizes into filaments that form microtubules and enable a cell to undergo mitosis would open the door to developing new anti-cancer drugs. Already, the natural substance known as Taxol had shown potential in treating a number of cancers by preventing a cell from dividing. It was vital to understand the tubulin structure and how it interacts with Taxol in order to create a more effective drug that targeted only cancer cells.
Downing’s lab was the first to create a 3-dimensional atomic model, and it was achieved through electron crystallography and cryo-EM. The resulting 3D model was a computerized reconstruction of 93 electron diffraction patterns and 159 images culled from more than 4,000 recorded over the previous six years. They were able to work with crystals only one molecule in thickness by obtaining diffraction patterns with an electron beam. In 1998, they achieved 3.7A resolution. Then in 2001, they refined the model to 3.5A resolution and published “Refined structure of alpha-beta tubulin at 3.5A resolution.” Instrumentation for this work includes the JEOL JEM-4000 and the JEM-3100F Transmission Electron Microscopes.
Dr. Wah Chiu
Director, National Center for Macromolecular Imaging
Baylor College of Medicine
Dr. Wah Chiu is renowned worldwide for his contributions to the field of electron cryomicroscopy. His lab has developed high throughput methods for imaging and solving 3-dimensional structures of macromolecular machines at atomic resolution. Biological applications include viruses, ion channels, membranes, oligomeric proteins and cyotskeletal protein complexes.
In recent publications, his team has looked beyond the highly symmetrical ball-like surface protein shell of the episilon15 bacteriophage that infects Salmonella bacteria. They have described different molecular parts involved in binding to host cells, injecting DNA into the cell and packaging it during the virus formation.
Additionally, Dr. Chiu’s recent work has included building the first atomic model directly from a single particle cryo-EM density map of Group II chaperonin, or mediator of cellular protein folding in eukaryotes and archaea.
Dr. Chiu is a professor in the BCM department of biochemistry and molecular biology, and the director of the National Center for Macromolecular Imaging. He has done extensive work using phase plate technology and JEOL TEMs - the models JEM-2200FS, JEM-2010, JEM-2100F, and JEM-3200F are used in his lab at Baylor College of Medicine.
