The lab uses electron microscopy to observe changes in materials in situ at the nanoscale.
AboutAbout the lab
Watching nanoscale changes inside an electron microscope
The Nanomaterials and Device Science Lab uses electron beams to observe, at the nanometer scale, the arrangement of the atoms and microstructures that make up a specimen.
Its research centers on "in situ observation," in which changes in microstructure, functions, and mechanical properties are watched in real time while heat, light, external force, and other stimuli are applied.
By combining this with data science and computational methods, the lab aims to establish microscopy techniques that can be used to explore unknown materials and evaluate their functions.
On the lab's website, the lab is introduced under the name "Murayama Lab."

ResearchResearch themes
The lab's research centers on in situ observation: applying heat, light, external force, and other stimuli to specimens inside an electron microscope and observing changes in microstructure, functions, and mechanical properties in real time. By combining this approach with data science and computational methods, the lab works to establish microscopy analysis methods that can be used to explore unknown materials and evaluate their functions, and to elucidate physical and chemical phenomena.
*Illustrative imageElectron microscopy integrated with machine learning
The lab aims to establish next-generation microscopy analysis methods that combine data science and computational methods with electron microscopy analysis of microstructures and local chemical composition. It also conducts research and education to understand the relationship between microstructure and functional and mechanical properties.
*Illustrative imageMeasuring interactions between resonators and emitters
The lab investigates interactions between resonators and emitters (light-emitting objects) using nanoscale optical measurements. The keywords are cathodoluminescence, nanophotonic cavities, and electron energy-loss spectroscopy.
