Computer program TRACK_VISION for simulating optical appearance of etched tracks in CR-39 nuclear track detectors
A computer program called TRACK_VISION for determining the optical appearances of tracks in nuclear track materials resulted from lightion irradiation and subsequent chemical etching was described. A previously published software, TRACK_TEST, was the starting point for the present software TRACK_VISION, which contained TRACK_TEST as its subset. The programming steps were outlined. Descriptions ...
متن کاملIncorporating Amphoteric Groups in Ion Track-etched Single Conical Nanochannels
Here, we report a facile and straight-forward approach to incorporate amphoteric groups inside the single conical nanochannels. This was realized by direct chemical modification of the surface carboxyl groups with L-lysine chains whose positive and negative charges are very sensitive to the external pH. The chemically functionalised channels were characterized both theoretically and experimenta...
متن کاملEngineering cell-fluorescent ion track hybrid detectors
BACKGROUND The lack of sensitive biocompatible particle track detectors has so far limited parallel detection of physical energy deposition and biological response. Fluorescent nuclear track detectors (FNTDs) based on Al₂O₃:C,Mg single crystals combined with confocal laser scanning microscopy (CLSM) provide 3D information on ion tracks with a resolution limited by light diffraction. Here we rep...
متن کاملThree-dimensional analytical determination of the track parameters: over-etched tracks
Three-dimensional analytical determinations of track parameters are extended to cases where the tracks are in the rounded and spherical phases of development. The equation for the track wall in three dimensions and the equation of contour line of the opening were derived for all types of tracks. The expression for the surface area of the track opening has also been found. The equations come up ...
متن کاملChemical bonds broken in latent tracks of light ions in plastic track detectors.
When a swift ion is slowed down through a plastic detector it creates a latent track. In nuclear track detectors, this latent track can be specifically etched by an appropriate chemical solution. This enlargement process is due to a higher etch velocity (VT) along the ion's path than in the non-damaged part of the detector. The etched track velocity is definitely linked to the damage created by...
