Measurement of ionization in nuclear emulsion by lacunarity technique

, 1970
This thesis explored "lacunarity" as a technique for measuring ionization and energy loss of charged particles in nuclear emulsion. Lacunarity is defined as the fraction of a track segment that consists of gaps. A comparison was made between lacunarity

Generating Electrospray Ionization on Ballpoint Tips

, 2016
In this study, we report a simple and economical ballpoint electrospray ionization mass spectrometry (BP-ESI-MS) technique. This combines a small ballpoint tip with a syringe pump for the direct loading and ionization of various samples in different ...

Ionization-Induced π → H Site Switching in Resorcinol–Ar_n (n = 1 and 2) Clusters Probed by Infrared Spectroscopy

, 2019
Infrared (IR) spectra of resorcinol (Rs)–Arn clusters (n = 1 and 2) have been measured in the neutral and cationic ground states (S0 and D0) by IR dip and resonance-enhanced multiphoton ionization (REMPI)-IR spectroscopy.
