Electrospray Propulsion Time-of-Flight Secondary Ion Mass Spectrometry Diagnostic [PDF]

open access: yesarXiv
The design and capability of a novel time-of-flight secondary ion mass spectrometry electrospray propulsion diagnostic is presented to investigate secondary species emission from surface impingement of high-velocity, energetic molecular ion plumes. Designed on the basis of traditional Secondary Ion Mass Spectrometry (SIMS) principles, this diagnostic ...

Variational autoencoders for tissue heterogeneity exploration from (almost) no preprocessed mass spectrometry imaging data [PDF]

open access: yesarXiv, 2017
The paper presents the application of Variational Autoencoders (VAE) for data dimensionality reduction and explorative analysis of mass spectrometry imaging data (MSI). The results confirm that VAEs are capable of detecting the patterns associated with the different tissue sub-types with performance than standard approaches.

Analysis of cell membrane aminophospholipids as isotope-tagged derivatives

open access: yesJournal of Lipid Research, 2005
Glycerophosphoethanolamine (GPEtn) and glycerophosphoserine (GPSer) lipids were reacted with a multiplexed set of differentially isotopically enriched N-methylpiperazine acetic acid N-hydroxysuccinimide ester reagents, which place isobaric mass labels at

Propellant Discovery For Electrospray Thrusters Using Machine Learning [PDF]

open access: yesarXiv
This study introduces a machine learning framework to predict the suitability of ionic liquids with unknown physical properties as propellants for electrospray thrusters based on their molecular structure. We construct a training dataset by labeling ionic liquids as suitable (+1) or unsuitable (-1) for electrospray thrusters based on their density ...

Top-Down Mass Spectrometry Imaging of Intact Proteins by LAESI FT-ICR MS [PDF]

open access: yesarXiv, 2013
Laser Ablation Electrospray Ionization is a recent development in mass spectrometry imaging. It has been shown that lipids and small metabolites can be imaged in various samples such as plant material, tissue sections or bacterial colonies without anysample pre-treatment.
