These contain ground-breaking conducting polymer composite membranes that will allow in-situ tuning of the molecular selectivity for both neutral and charged species through them.
Specific topics include elementary processes of charged species in plasma, plasma statistics and kinetics of charged particles in plasma, glow discharge, non-equilibrium cold atmosphere pressure discharges, and electron beam plasmas.
One explanation of this phenomenon, based on this initial observation, could be that the multiple charges present on biomolecules created a higher electrical imbalance within the droplet, thus enhancing ejection of gas phase ions when compared with similar droplet stoichiometry for singly charged species.
Until recently, only neutral and positively charged species had been detected.
Anion binding process which involves non-covalent interactions, namely electrostatic and hydrogen bonding interactions between a receptor and a negatively charged species, constitute a major challenge as compared to the cation binding.
Similar to an electron microscope, the LG-2 uses helium ions rather than electrons as the charged species that probe surfaces.
NTP is created with a high-voltage electrical energy source and is comprised of charged species (electrons and ions), active chemical species (radicals like ozone) and ultraviolet radiation.
Using the conservation of the charged species, assuming no chemical reaction, the ionic transport equation can be written as,
One such method is ion exchange, which uses polystyrene-based resins containing positively charged sites to remove negatively charged species.
The phenomenon of the migration of charged species under the influence of an externally applied electric field is known under the name of electrophoresis.
Capillary electrophoresis (CE) is a popular and powerful separation technique based on the differential migration of charged species in an electric field.
Consequently, it was concluded that this effect was determined by the dissolution of the charged species in water.
