A new method for atomic-resolution electron microscopes

Electron lens formed by light

13-Apr-2022 - Electron microscopy enables researchers to visualize tiny objects such as viruses, the fine structures of semiconductor devices, and even atoms arranged on a material surface. Focusing down the electron beam to the size of an atom is vital for achieving such high spatial resolution. However, when ...

A single molecule makes a big splash in the understanding of the two types of water

“Because water plays such an important role in chemistry and biology, and even in understanding our universe, we expect our findings to have a wide-ranging impact”

10-Jan-2022 - It plays a fundamental role in human existence and is a major component of our universe, yet there are still things we don’t understand about water. To address the knowledge gaps, a collaborative team of Institute of Industrial Science, The University of Tokyo, Kyoto University, and Tohoku ...

Novel two-step mechanism revealed in two-dimensional material formation

Novel monitoring and analysis method

10-Dec-2021 - Two-dimensional materials are incredibly thin. Typically only an atom thick, 2D materials exhibit highly desirable properties for advanced technologies, such as flexibility, superconductivity and more. Made from carefully transitioning individual components from gas or vapor to crystalline ...

Scanning the surface of lithium titanate

07-Jul-2017 - Researchers at Tokyo Institute of Technology, Tohoku University and the University of Tokyo have applied advanced scanning methods to visualize the previously unexplored surface of a superconductor: lithium titanate (LiTi2O4). LiTi2O4 is the only known example of a so-called spinel oxide ...

How X-rays in matter create genetoxic low-energy electrons

02-Feb-2017 - Researchers led by Kiyoshi Ueda of Tohoku University have investigated what x-rays in matter really do and identified a new mechanism of producing low-energy free electrons. Since the low-energy electrons cause damage to the matter, the identified process might be important in understanding and ...

Controlling ultrafast electrons in motion

25-Feb-2016 - An international team has used the light produced by the Free Electron Laser FERMI at the research Centre Elettra Sincrotrone Trieste in the AREA Science Park to control the ultrafast movement of electrons. The experiment opens the way to the study of more complex processes which occur in nature ...
