The Expanding Role of Electrospray Ionization Mass Spectrometry for Probing Reactive Intermediates in Solution

open access: yesMolecules, 2012
Within the past decade, electrospray ionization mass spectrometry (ESI-MS) has rapidly occupied a prominent position for liquid-phase mechanistic studies due to its intrinsic advantages allowing for efficient “fishing” (rapid, sensitive, specific and ...

MassGenie: A Transformer-Based Deep Learning Method for Identifying Small Molecules from Their Mass Spectra

open access: yesBiomolecules, 2021
The ‘inverse problem’ of mass spectrometric molecular identification (‘given a mass spectrum, calculate/predict the 2D structure of the molecule whence it came’) is largely unsolved, and is especially acute in metabolomics where many small molecules ...

Chitin Nanofibril Application in Tympanic Membrane Scaffolds to Modulate Inflammatory and Immune Response

open access: yesPharmaceutics, 2021
Chitin nanofibrils (CNs) are an emerging bio-based nanomaterial. Due to nanometric size and high crystallinity, CNs lose the allergenic features of chitin and interestingly acquire anti-inflammatory activity. Here we investigate the possible advantageous

Computationally examining the effect of plate thickness on hole emitter type electrospray thrusters [PDF]

open access: yesarXiv, 2022
A new method for determining the onset voltage of electrospray thrusters is proposed, which specifically focuses on electrospray thrusters manufactured by laser drilling through flat plates. The novelty of this method is that it accounts for the effect of the thickness of the plate on the electrospray onset voltage requirements, while traditional ...

On the use of hypodermic needles in electrospray [PDF]

open access: yesEPJ Web of Conferences, 2013
EPJ Web of Conferences, 54, 01128-2 - 01128-5 We present an experimental analysis of electrospray where the standard feeding capillary was re placed with a hypodermic needle. Both the current intensity and the jet diameter were measured for a variety of leaky-dielectric liquids. The results obtained with a feeding capillary and a hypodermic needle
