Nanomaterials Microstructure Analysis Lab
Machine-translated · View original
The lab analyzes the fine structures of materials at the atomic scale using electron microscopy.
AboutAbout the lab
Unraveling the nanostructures of materials with electron microscopy.
The Nanomaterials Microstructure Analysis Lab examines the structures of crystalline materials such as metals and ceramics using transmission electron microscopy (TEM).
It analyzes the two-dimensional and three-dimensional nanostructures that form in materials at the nano and atomic scales.
The lab aims to gain knowledge that improves the performance of materials and thereby contribute to society.
On the lab's website, it is listed as the "Kaneko Lab."
Key terms
- Transmission electron microscope
- A microscope that passes an electron beam through a thinned specimen and can observe the internal structure down to the atomic scale. Abbreviated as TEM.
- Precipitate
- A particle that appears in an alloy when some of its elements gather and solidify.
- Cluster
- A small aggregate formed in a metallic material when added elements gather together.
ResearchResearch themes
Crystalline materials such as metals develop fine structures such as surfaces, grain boundaries, and dislocations, which govern properties such as strength, ductility, and catalytic activity. The lab uses transmission electron microscopy (TEM), which allows observation at the atomic scale, to clarify the relationship between properties and microstructure and to lead to the development of new materials.
*Illustrative imageMicrostructure analysis of various materials
Using TEM, the lab analyzes the microstructures of steels, aluminum alloys used in automobile body panels, platinum nanoparticles essential for fuel cells, and other materials. It also investigates the interfaces of semiconductor devices and the structures of catalyst nanoparticles.
*Illustrative imageObserving nanoprecipitates in Al alloys at the atomic scale
With state-of-the-art TEM, nanoprecipitates in Al alloys can be observed at the atomic scale, and the types of elements that compose them can also be identified. Precipitates are the main factor that strengthens an alloy. Once their composition and structure are known, it becomes possible to propose alloy compositions that give finer, higher-density precipitation.
*Illustrative imageAnalysis of clusters in metallic materials
The lab uses TEM to analyze clusters formed when added elements gather together in metallic materials. It is becoming clear that these clusters may have short-range ordered structures rather than being merely random aggregates, and the lab is working to clarify part of their origin.
