Time‐of‐Flight Secondary Ion Mass Spectrometry‐Partial Least Square Regression for Quantifying Interleukin‐8 in Biopolymer Matrices

Advanced NanoBiomed Research
Unraveling the complexity of biomatrices is a persisting challenge in many areas of the life sciences. The detection of soluble signaling molecules—cytokines and growth factors—within multicomponent biopolymer scaffolds is of particular interest as they ...

Characterization of silicon-based chromium (VI) replacement coatings by using time-of-flight secondary ion mass spectrometry and salt spray tests

Results in Surfaces and Interfaces
This paper proposes an innovative approach in characterization of silicon-based chromium (VI) replacement coatings on an Al substrate by using, salt spray tests and time-of-flight secondary ion mass spectrometry (ToF-SIMS) performed in profile mode by a ...

Multistaged discharge constructing heterostructure with enhanced solid-solution behavior for long-life lithium-oxygen batteries. [PDF]

, 2019
Inferior charge transport in insulating and bulk discharge products is one of the main factors resulting in poor cycling stability of lithium-oxygen batteries with high overpotential and large capacity decay.

TOF-SIMS in Cosmochemistry

, 2004
Time-of-flight secondary ion mass spectrometry (TOF-SIMS) was introduced into cosmochemistry about a decade ago. Major advantages of TOF-SIMS compared to other ion microprobe techniques are (a) parallel detection of all secondary ions with one polarity in a single measurement – both polarities in subsequent analyses, (b) high lateral resolution, (c ...

TOF-SIMS Imaging of Lipids on Rat Brain Sections

, 2014
Since several decades, secondary ion mass spectrometry (SIMS) coupled to time of flight (TOF) is used for atomic or small inorganic/organic fragments imaging on different materials. With the advent of polyatomic ion sources leading to a significant increase of sensitivity in combination with a reasonable spatial resolution (1-10 μm), TOF-SIMS is ...

The structural and electrical properties of thermally grown TiO2 thin films

, 2006
We studied the structural and electrical properties of TiO2 thin films grown by thermal oxidation of e-beam evaporated Ti layers on Si substrates. Time of flight secondary ion mass spectroscopy (TOF-SIMS) was used to analyse the interfacial and chemical ...
