Effects on insulators of swift-heavy-ion irradiation: ion-track technology

Journal of Physics D: Applied Physics, 1998
Polymers (CR-39, SR-86 and Makrofol-KG) and glasses (soda lime and barium phosphate) were irradiated using ions from the 15UD Pelletron at the NSC, New Delhi. The beam energy was fixed at 60 MeV and the fluence was varied in the range -. Irradiation effects were studied using UV-visible and IR spectroscopic techniques. For all the polymer targets there

Technological Applications of Ion Tracks in Insulators

MRS Bulletin, 1995
Natural nuclear tracks in solids have existed since close to the beginning of the solar system, billions of years ago. Only during the last few decades have we learned how to employ tracks practically. Uses now range from radiation dosimetry to microchemical analysis, virus counting, oil and uranium exploration, and aiding earthquake prediction.

Incorporation technology of fullerene and conductive properties of fullerite in ion tracks of polymer film

2001 Siberian Russian Student Workshop on Electron Devices and Materials. Proceedings 2nd Annual (IEEE Cat. No.01EX469), 2002
We have shown in first test experiments that fullerite can be deposited along etched ion tracks in polymers via simple deposition technology from high concentrated solution of fullerene in toluene. We have tried to deposit semiconducting fullerite along etched in KOH solution ion tracks with several hundred nanometers diameter in polymer foil of 10 ...

Asymmetric ion track nanopores for sensor technology. Reconstruction of pore profile from conductometric measurements

Nanotechnology, 2012
We reconstruct the profile of asymmetric ion track nanopores from an algorithm developed for conductometric measurements of symmetric nanopores. The validity of the reconstruction is supported by FESEM observations. Our analysis reveals that asymmetric pores fabricated by one-sided etching are funnel-like and not conical.

Ion Tracks in Solids: From Science to Technology to Diverse Applications

MRS Bulletin, 1995
Fast ions create linear trails of intense atomic disorder in many solids. Theparticle tracksare in themselves scientifically interesting because they consist of unique, localized radiation damage. They also are noteworthy for their diverse practical uses, which range from improved high field superconductors to mineral exploration and bird altimetry ...

Improving thin film flexible supercapacitor electrode properties using ion-track technology

Journal of Materials Science: Materials in Electronics, 2018
A novel self-supporting carbon thin film flexible supercapacitor electrode with high volumetric and areal capacitance was developed. The increase in capacitance performance is achieved by introducing channels across the carbon thin film using ion-track technology. In the first step of the electrode synthesis, latent tracks are inscribed in the starting

Surfactant-controlled etching of ion track nanopores and its practical applications in membrane technology

Radiation Measurements, 2008
The effect of surfactants on chemical development of ion tracks in polymers has been studied. It has been shown that surface-active agents added to an alkaline etching solution adsorb on the polymer surface at the pore entrances. This reduces the etch rate, which leads to the formation of pores tapered toward the surface.

Polyimide microfluidic devices with integrated nanoporous filtration areas manufactured by micromachining and ion track technology

Journal of Micromechanics and Microengineering, 2003
This paper reports on polyimide microfluidic devices fabricated by photolithography and a layer transfer lamination technology. The microchannels are sealed by laminating an uncured polyimide film on a partially cured layer and subsequent imidization.

Improved Simulation of Ion Track Structures Using New Geant4 Models—Impact on the Modeling of Advanced Technologies Response

IEEE Transactions on Nuclear Science, 2012
New “MuElec” models and processes are developed and implemented in Geant4 for the generation of low energy electrons in silicon by incident electrons, protons and heavy ions. They allow a more accurate modeling of proton and ion tracks; differences are clearly seen as compared to the tracks previously obtained with the already available Geant4 low ...
