This chapter describes two examples where single-ion tracks are used as critical apertures ruling the flow between two adjacent reservoirs of a fluid. First, the classical flow of an aqueous suspension of microparticles. Second, the quantum mechanical flow of a superfluid.

During track development the damaged zone of the latent track is either transformed chemically or removed by an etchant, leading to the observable track, the end-product of all the preceding steps and ultimate goal of a structuring tool.

Radiation Effects and Defects in Solids, 2006
It is a common practice since long to follow the ion track-etching process in thin foils via conductometry, i.e. by measurement of the electrical current which passes through the etched track, once the track breakthrough condition has been achieved.

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 ...

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.

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.
