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...

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...

By assuming that HO2 ● radical production in water and H2 production in benzene are 2 hit processes, and applying the concepts of track physics, we are able to obtain a parametric fit to the yields of these reactions by heavy ion radiolysis from knowledge of the radial dose distribution about a heavy ion’s path. We make no use of the concept of a track core, for no clearly definable track core ...

Heavy ion tracks in polymer membranes can be transformed into microand nano-channels by means of wet-chemical etching. Up to now most commonly polycarbonate (PC), polyethylene therephthalate (PET) and polyimide (PI) membranes were employed for this purpose. For some applications such as proton conductive membranes for fuel cells, high resistance of the material against heat and solvents as well...

This work presents a novel process to fabricate nanostructures for thermoelectric applications by a combination of a traditional silicon microfabrication techniques, electroplating, and submicron ion-track nanolithography. Polyimide (Kapton HN, PI2731), and PMMA (polymethyl methacrylate) were ion-track irradiated and wet etched. Bi2Te3 nanowires (80 and 120 nm diameter) were electroplated with ...

Fission tracks in minerals, such as apatite and zircon, generated by energetic nuclear fragments that result from spontaneous fission of U, are used for determining the age and thermal history of Earth’s crust. Taken together with other techniques, the data infer rates of tectonic uplift and landscape evolution [1]. At elevated temperatures, these tracks shrink in size and fragment into section...
