On the dyeing of ion tracks in polymers
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1996Abstract Latent ion tracks in polymers can incorporate dyes at high concentrations. This is of interest in a number of applications. Dyes may also be used as sensitive probes to study the fine structure of latent ion tracks. In this work, we discuss the dependence of dye uptake on both time and mean transferred electronic energy density, and also ...

Electronic excitations produced by ions in polymers results in the formation of free radicals making them highly sensitive to chemical agents. Besides the widely developed application to the etching of membranes with controlled pore sizes and densities, the grafting of molecules selected for their chemical properties inside the tracks of swift heavy ...

Micromachining by ion track lithography
Sensors and Actuators A: Physical, 1999Abstract Micromachining by ion track etching (MITE) based on the lithographic projection of a mask onto an arbitrary ion track recording material using a parallel beam of highly energetic heavy ions, is described here. By this, deep microstructures have been produced in single crystalline quartz, phlogopite mica, polycarbonate, polyimide, and soda ...

Swift heavy ions with energies of about 5 MeV/u cause a high energy deposition into solid targets. As a consequence first the electronic system receives energy and afterwards the energy is transferred to the atomic system by electron phonon coupling or Coulomb repulsion.

Formation of ion damage tracks
Physics Letters A, 1984The formation of damage tracks in insulators from the passage of energetic (MeV/amu) ions indicates that the energy lost by an ion to electronic excitation is partially transferred to atomic motion. It is known that a track consists of localized regions of extended defects that are separated by lengths that exhibit only point defects.

Tracking lithium ions in an electrolyte
C&EN Global Enterprise, 2017Over time, lithium-ion batteries need more frequent recharging. And on rare occasions, the batteries can catch fire when lithium builds up on the anode, forming sharp spikes that pierce the membrane that separates the anode from the cathode. A new way to directly image lithium ions could help researchers better understand why these problems happen (ACS

Contemporary investigations of swift heavy ion irradiated A2B2O7 pyrochlores are driven by the interest in their use for the immobilisation of nuclear waste [1, 2]. Employed techniques (X-ray diffraction, transmission electron microscopy, Raman spectroscopy) provide detailed insight into pyrochlore response to fission-fragment like radiation.

Physical Background of Ion Tracks
2018When energetic ions pass through solids, they dissipate their energy into the target. The resulting energy loss can be divided into two main regimes. The first is nuclear energy loss, which displaces atoms by elastic collisions between the ion and the nuclei.

Micro- and Nanoengineering with Ion Tracks
2009In nature, particle tracks are formed over millions of years whenever radioactive elements decay by fission processes, producing energetic fragments of sufficiently large mass (∼ 100 u) and energy (∼ 100 u).
