Ionization and structural properties of mRNA lipid nanoparticles influence expression in intramuscular and intravascular administration

Communications Biology, 2021
Lipid Nanoparticles (LNPs) are used to deliver siRNA and COVID-19 mRNA vaccines. The main factor known to determine their delivery efficiency is the pKa of the LNP containing an ionizable lipid.

Development of a multiwire position sensitive proportional counter [PDF]

Nuclear Technology and Radiation Protection, 2011
Preliminary measurements in a proportional counter with two independently counting wires have shown that counting rates up to 106 counts/s per wire can be reached without critical loss in the “true versus measured” linearity relation. In this paper, a

Light Dark Matter Search with Ionization Signals in XENON1T. [PDF]

Physical Review Letters, 2019
We report constraints on light dark matter (DM) models using ionization signals in the XENON1T experiment. We mitigate backgrounds with strong event selections, rather than requiring a scintillation signal, leaving an effective exposure of (22±3) tonne ...

Moving toward a Handheld “Plasma” Spectrometer for Elemental Analysis, Putting the Power of the Atom (Ion) in the Palm of Your Hand

Molecules, 2021
Many of the current innovations in instrument design have been focused on making them smaller, more rugged, and eventually field transportable. The ultimate application is obvious, carrying the instrument to the field for real time sample analysis ...

Authentication and Testing of Banknotes Using Laser Multiphoton Electron Extraction Spectroscopy (MEES)

Applied Sciences, 2021
In laser multiphoton electron extraction spectroscopy (MEES), the photo-charges extracted from a surface by a pulsed laser beam are recorded as a function of laser wavelength. We report the first application of this spectroscopy to banknotes.

Optimizing ideal ion propulsion systems depending on the nature of the propellant [PDF]

INCAS Bulletin, 2016
From all accounts the ion thrusters are characterized by the fact that they produce a very high exhaust velocity and specific impulse, sometimes too high for many missions.
