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

Journal 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

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.

Ion tracks and microstructure technology

International Journal of Radiation Applications and Instrumentation. Part D. Nuclear Tracks and Radiation Measurements, 1988
Abstract Present-day microtechnology depends very much on the availability of suitable lithographic techniques for generating smaller and smaller structures. On this road, conventional techniques using light particles, such as photons or electrons, are approaching their technological limits.

Tunable nanoporous silicon oxide templates by swift heavy ion tracks technology

Nanotechnology, 2016
Nanoporous silicon oxide templates formed by swift heavy ion tracks technology have been investigated. The influence of the heavy ion characteristics, such as type of ion, energy, stopping power and irradiation fluence on the pore properties of the silicon oxide templates, has been studied. Furthermore, the process of pore formation by chemical etching

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 ...

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.
