Real-time measurements made of NOx (by chemiluminesence), black carbon (BC) (by light absorption), particulate matter-phase PAH (by UV ionization), and particle length (by diffusional charging) showed high correlations with UFP numbers, (r2= 0.78 for NO, 0.76 for BC, 0.69 for PAH, and 0.88 for particle length).
The Advanced Innovation Center (AIC) has developed a system that converts water into a plasma state through a high-intensity electrical field and eliminates microbiological content through electroporation, oxidation, ionization, UV and IR radiation, and shockwaves.
Ultraviolet (UV) irradiation and ionization radiation can fractionate the DNA double-stranded structure, and activate the p53 synthesis process that subsequently induces the DNA damage signal transduction system.
Harvested medium was immunoprecipitated using the mAb4G8 antibody (Cell Sciences, Canton, MA), and the immune precipitates were extracted with a trifluoroacetic acid/water/acetonitrile mixture [1/20/20 (v/v/v)] and subjected to matrix-assisted UV laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) as described previously.
Although the extremely small size of these particles makes direct optical observation of them impossible, in situ observations of their ionization by UV radiation was used to show the electrodynamic effects of temperature variations in the lower mesosphere and upper stratosphere.
A combination of known responses in UV absorption and MS ionization efficiency from the mother compound with the rationale that metabolites with similar structures often give similar responses can however give an estimate of the abundance of each metabolite in a mixture, but never absolute quantification can be done.
GmF3G2″G-a and GmF3G2″G-b converted kaempferol 3- O-glucoside to kaempferol 3- O-sophoroside as confirmed by comparison of retention time, UV spectra and MS/MS ionization with the standard compound.

The paper said that both X-radiation and UV-radiation produce ionizations.
In the dark, these functionalities will be uncharged and the channel will stay closed, but UV illumination will cause their ionization and trigger channel activity.
Digested samples were analyzed by peptide mass mapping using reversed phase chromatography with in-line UV (214 nm) and electrospray ionization with mass spectrometric detection (LC-ESI-MS).
