The article offers news brief on 3D printing that discusses researchers have used a scanning transmission electron microscope, or STEM, at the Ridge National Laboratory to inject silicon atoms in a single-atom thick sheet of graphene to manipulate atoms while preserving the sample’s stability.

The article explores how to improve solid oxide electrolyte performance in a reduced temperature range by mitigating the blocking effect of grain boundaries. Increased ionic conductivity in yttria-stabilized zirconia by smoothing grain boundaries by doping with lanthanum is mentioned. The use of scanning transmission electron microscopy-based energy dispersive spectroscopy is cited.

The article discusses a study by researchers at North Carolina State University led by Doug Irving and James LeBeau which pioneered the use of an imaging method called revolving scanning transmission electron microscopy (STEM) that allows the accurate mapping of distortions in the atomic organization of a material. Topics discussed include the lanthanum strontium aluminum tantalum oxide (LSAT) ceramic superconductor substrate, and surmounting the drift or minute sample movement.

The article reports the claim by scientists at Oak Ridge National Laboratory (ORNL) in the U.S. as of late 2014 that garnet ceramics could help achieve safer and longer-life lithium-ion (Li-ion) batteries. In the cubic garnet ceramic Li7La3Zr2O12 (LLZO) study, the scientists used scanning transmission electron microscopy and electron energy loss spectroscopy to examine its structure. The comment by scientist Miaofang Chi on their study is cited.

The article discusses a study by material scientist James M. LeBeau and others, published in the journal "Applied Physics Letters" in 2015, who visualized the location of atoms in a lanthanum, strontium, aluminum and tantalum (LSAT) oxide crystal using scanning transmission electron microscopy.

The article focuses on the professional career of researcher Pratibha L. Gai. It informs that Gai and her coworkers have developed an environmental scanning transmission electron microscope (ESTEM) and she has become the first researcher to view individual atoms interacting with each other in real time under controlled reaction conditions. It mentions that Gai has published 250 peer-reviewed papers and received three million U.S. dollars for developing a nanoparticle catalyst.

The article reports that Jing Lu, Bruce C. Gates and colleagues at the University of California, Davis have successfully identified the locations of individual catalytically active gold atoms in a zeolite support material using scanning transmission electron microscopy.

The article reports that Oak Ridge National Laboratory has used high-resolution z-contrast scanning transmission electron microscope which can be useful for future chemical studies on atoms.

The article reports that researcher Ilke Arslan and colleagues at Sandia National Laboratories in the U.S. have assembled the first three-dimensional experimental images of cobalt-based catalysts used in Fischer-Tropsch processes to convert synthesis gas to hydrocarbon fuels and feedstocks. The researchers used scanning transmission electron tomography to study two catalyst combinations of cobalt and rhenium.

The article evaluates the SuperSTEM 2 Scanning Transmission Electron Microscope from Daresbury Laboratory in Warrington, Cheshire, England.
