Imaging and quantitative analysis of insecticide in mosquito net fibers using Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS).

open access: yesPLoS ONE, 2018
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) analysis was used to qualitatively and quantitatively assess the distribution of permethrin insecticide on the surfaces and interiors of Olyset long-lasting insecticidal net (LLIN) fibers.

The role of a diffusion barrier in plasma display panel with the high gamma cathode layer [PDF]

open access: yes, 2011
Plasma display panel (PDP) with MgO-SrO double cathode layer and SiO(2) diffusion barrier is proposed to make the SrO layer free of contaminations. Time of flight-secondary ion mass spectrometry (TOF-SIMS) analysis shows the diffusion of impurities, like
