Electron microscopy is a powerful tool for visualizing the shapes of sub-nanometer objects. However, Contrast Transfer Function (CTF) principally restricts lower frequency components in the image. To overcome this problem, phase-plate techniques have

Muon-catalyzed fusion (μCF) is a cyclic reaction where a negatively charged muon acts as a catalyst for nuclear fusion between hydrogen isotopes. The muon exists in the molecular orbital of the unifying nuclei during the nuclear fusion. The muon wit

Recycling muon having approximately 10 keV kinetic energy produced in a muon catalysed fusion ( μ CF) cycle is expected to be a source of negative muon beam with high-spatial/time coherence. We report a time evolution calculation of μ CF cycle with

High-voltage transmission electron microscopes (HVTEMs), which can visualize internal structures of micron thick samples, intrinsically have large instrument sizes because of the static voltage isolation. In this Letter, we develop a compact HVTEM, e

Developments in X-Ray Tomography XII.
Quantitative measurements of the phase shift of X-rays passing through a matter allow us to perform X-ray phase tomography for visualization of soft materials. Combination of an X-ray microscope and a grating interferometer is a promising approach to

X-ray phase contrast imaging offers a complementary modality next to conventional absorption. To reveal internal structures of soft materials in high resolution, an X-ray phase imaging microscope has been developed by installing a Lau interferometer

We propose that any black hole has atomic structure in its inside and has no horizon as a model of black holes. Our proposal is founded on a mean field approximation of gravity. The structure of our model consists of a (charged) singularity at the ce
