Secondary electro-spray ionization (SESI) is an ambient ionization technique for the analysis of trace concentrations of vapors, where a nano-electrospray produces charging agents that collide with the analyte molecules directly in gas-phase. In the subsequent reaction, the charge is transferred and vapors get ionized, most molecules get protonated (in positive mode) and deprotonated (in negative mode). SESI works in combination with mass spectrometry or ion-mobility spectrometry. (Wikipedia).
Ionization Energy - Basic Introduction
This chemistry video tutorial provides a basic introduction into Ionization Energy. It discusses the periodic trends and exceptions as well as providing plenty of examples and practice problems. The first ionization energy is the energy required to remove an electron from a gaseous atom

Annabelle Collin - Mathematical models of electroporation validated on medical data
Electroporation is a complex phenomenon that occurs when biological tissues are subjected to electric pulses. Electroporation makes it possible to either kill directly the cells in the target region (tumor) or to introduce molecules into living cells. However, one of the main limitation of
