Compositional, ultrastructural and nanotechnological characterization of the SMA strain of Saccharomyces pastorianus: Towards a more complete fermentation yeast cell analysis. [PDF]

PLoS ONE, 2018
Nano scanning Auger microscopy (NanoSAM) and time-of-flight secondary ion mass spectrometry (TOF-SIMS) have been used in materials science research for some time, but NanoSAM, in particular, has only recently been applied to biological specimens.

TOF-SIMS characterization of planktonic foraminifera [PDF]

Applied Surface Science, 2003
Abstract Oceanic sediment properties that are closely related to former environmental (e.g. climatic) parameters are called “proxies”. Planktonic foraminifera are small protists which make up part of the plankton. Certain element concentrations, element ratios and isotopic ratios of their calcite shell found in the sediment can be used as proxies ...

Multi-dimensional TOF-SIMS analysis for effective profiling of disease-related ions from the tissue surface [PDF]

Time-of-flight secondary ion mass spectrometry (TOF-SIMS) emerges as a promising tool to identify the ions (small molecules) indicative of disease states from the surface of patient tissues.

Superlubricity mechanism of diamond-like carbon with glycerol. Coupling of experimental and simulation studies [PDF]

, 2007
We report a unique tribological system that produces superlubricity under boundary lubrication conditions with extremely little wear. This system is a thin coating of hydrogen-free amorphous Diamond-Like-Carbon (denoted as ta-C) at 353 K in a ta-C/ta-C ...

ToF-SIMS characterization of uranium hydride

Philosophical Magazine Letters, 2007
Time-of-flight secondary-ion mass spectrometry (ToF-SIMS) has been employed for the first time to investigate uranium hydride. The deuterated form of uranium hydride (UD3) was formed on a polycrystalline uranium sample by exposure to high-purity D2 gas at room temperature.
