Transmission Electron Microscopy

There are multiple ways to create two- and three-dimensional models of atoms and molecules. With the advent of cutting-edge apparatus that can image samples at the atomic scale, scientists found that traditional molecular models did not fit the images they saw. Researchers have devised a better way more

Scientists have already been able to demonstrate that graphene nanostructures can be generated by annealing of a nanostructured silicon carbide crystal for a few years. “These two-dimensional, spatially strongly restricted carbon bands exhibit a vanishingly small electrical resistance even at room t more

Electron microscopes provide deep insight into the smallest details of matter and can reveal, for example, the atomic configuration of materials, the structure of proteins or the shape of virus particles. However, most materials in nature are not static and rather interact, move and reshape all the more

The aggregation behavior of a phenol-substituted thiacarbocyanine Cy5 dye (5-chloro-2-[5-[5-chloro-3-(4-sulfobutyl)-3H-benzothiazol-2-ylidene]-3-phenyl-penta-1,3-dienyl]-3-(4-sulfo¬butyl)-benzothiazol-3-ium hydroxide, inner salt, triethylammonium salt) in aqueous solution is investigated using stead more

We report in situ atomic-scale transmission electron microscopy observations of the surface dynamics during Cu2O reduction. We show inhomogeneous oxide reduction caused by the preferential adsorption of hydrogen at step edges that induces oxygen loss and destabilizes Cu atoms within the step edge, t more

A facile and eco-friendly method was developed to prepare a microporous CuO@Ag0 core–shell with high catalytic and antibacterial activities. Scanning and transmission electron microscopy revealed a preponderance of nearly spherical 50 nm particles with slight structure compaction. Comparison of the more
