Atom-by-Atom Determination of Deuterium Atom Distribution in the Surface by Atom Probe.

open access: yesSHINKU, 1998
Hydrogen is a major residual gas constituent in extremely high vacuum (XHV) and its outgassing behavior has been suggested to be closely related to its concentration and distribution in the surface layers of materials used to fabricate vacuum chambers.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Light, humor and atoms: The physics of wine after Galilei

open access: yesGalilæana
Galileo’s interest in the nature and composition of wine, summarised in the saying “wine is a compound of humour and light” that is often ascribed to him, provided the basis for the research of the subsequent generation of scientists.
