<title>Abstract</title>The dynamics of hydrogen in metals with mixed grain structure is not well understood at a microscopic scale. One of the biggest issues facing the hydrogen economy is “hydrogen embrittlement” of metal induced by hydrogen ente...
We have improved an electron stimulated desorption (ESD) apparatus to obtain the time evolution of hydrogen permeation for cold-worked stainless steel. Hydrogen permeation through grain structures was visualized by using the operando hydrogen micr...

Time-of-flight secondary ion mass spectrometry (TOF-SIMS) imaging provides ten-nanometer-scale chemical images of biodevices. It is one of the most sensitive surface analysis methods and has recently been applied in life sciences. TOF-SIMS is usef...
