Time-of-flight secondary ion mass spectrometry fragment regularity in gallium-doped zinc oxide thin films

Scientific Reports, 2021
Time-of-flight secondary ion mass spectrometry fragment analysis remains a challenging task. The fragment appearance regularity (FAR) rule is particularly useful for two-element compounds such as ZnO.

Association of GM4 Ganglioside with the Membrane Surrounding Lipid Droplets in Shark Liver

Journal of Lipid Research, 2002
By TLC, GM4 was found to be the major ganglioside in the liver of six shark species examined: Odontaspis taurus, Negaprion brevirostris, Sphyrna lewini, Mustelus griseus, Mustelus manazo, and Prionace glauca. A detailed analysis of the glycosphingolipids

Hydrogen Reduction in MEP Niobium Studied by Secondary Ion Mass Spectrometry (SIMS)

Metals, 2017
Niobium, as pure metal and alloying element, is used in a variety of applications, among them in nuclear industries. Niobium is incorporated into nuclear fission reactors due to its enormous strength and low density. Surface finishing of niobium is often

Nanoscopic subcellular imaging enabled by ion beam tomography

Nature Communications, 2021
Secondary ion beam mass spectrometry (SIMS) is a method to obtain a chemical snapshot of biological tissue, but the spatial resolution is low. Here, the authors develop a computational and technology pipeline to localise a chemical signal in SIMS in 3D ...

Time-of-Flight Secondary Ion Mass Spectrometry Analyses of Self-Assembled Monolayers of Octadecyltrimethoxysilane on SiO₂ Substrate

Applied Sciences, 2022
The self-assembled monolayers (SAMs) of organosilanes formed on an oxide substrate are thought to have a polymerized –Si–O–Si– network due to the homocondensation of silanols of hydrolyzed silane headgroups, which is the most significant difference in ...
