Nature Reviews Immunology, 2006
Accurate cellular localization is crucial for the effective function of most signalling molecules and nuclear translocation is central to the function of transcription factors. The passage of large molecules between the cytoplasm and nucleus is restricted, and this restriction affords a mechanism to regulate transcription by controlling the access of ...

Kapton nuclear track microfilter
International Journal of Radiation Applications and Instrumentation. Part D. Nuclear Tracks and Radiation Measurements, 1988Abstract Experiments were performed to produce Kapton nuclear track microfilters (Kapton is a Polyimide, produced by Du Pont). The Kapton foils were irradiated with uranium ions at three different energies at the UNILAC (GSI, Darmstadt) and then etched in NaClO solution.

Nuclear Tracks and Radiation Measurements, 1993
Abstract Polyvinylidene Fluoride (PVDF) nuclear track membrane (NTM) has been recently developed by chemical etching of “solef” (trade name) foils which are 50mm in diameter and 40 microm in thickness. The irradiation of “solef” were carried out by using various heavy ions with different specific energies at UNILAC (GSI Darmstadt, Germany).PVDF is a ...

Nuclear Instruments and Methods, 1979
Abstract The use of nuclear track emulsions in nuclear physics research is described with particular emphasis on their employment as focal-plane detectors. A brief description of nuclear emulsions and the theory of the photographic process is given in order to sketch the available opportunities to vary their sensitivity and other properties.

Improvement of overlapping nuclear track densitometry
Journal of Microscopy, 2015SummaryDetection of tracks produced by α particles, protons or nuclear fission fragments in plastic detectors, viz., solid‐state nuclear track detectors, constitutes a very important tool in various areas. It is not easy for humans to count CR‐39 nuclear tracks manually, especially when the track density is very high.

Contemporary Physics, 1976
Abstract It is little more than sixty years ago that the first of the particle-track devices, the cloud chamber, transformed ways of visualizing details of nuclear processes, and contemporary comment bears witness to the impact it made on workers who now saw, before their very eyes, the trajectories of charged particles, sometimes of their initial ...

Solid State Nuclear Track Detectors
Journal of Materials Science, 1980The materials science aspects of the use of both polymeric and inorganic solids as detectors for energetic particles are reviewed. The various models proposed to explain the formation of an etchable track by a penetrating particle are discussed, as is the nature and the geometric consequences of the etching process itself.

Nuclear track detectors in astroparticle and nuclear physics
Radiation Measurements, 2008Results obtained by the use of nuclear track detectors in astroparticle and nuclear physics are presented. In particular, results of the searches for magnetic monopoles, nuclearites and other exotica in the cosmic radiation and an application for the determination of the charge spectrum of primary cosmic ray particles are discussed. Examples of the use

Nuclear tracks in sinterized gemstones
Nuclear Tracks and Radiation Measurements, 1993Abstract The responses of sinterized gemstones to alpha particles attempt analyzed with the objective of finding new materials for SSNTD, and also to understand their interaction with radiation and the formation of tracks. In this work we present the results of the characterization of these materials as SSNTD.

Connections of one discovery to another are often unpredictable. Who would reason that imaginings of stored damage by cosmic particles that enter lunar rocks would lead to widespread technological applications? Yet uses of such damage range from draft beer that can be stored at room temperature to im proved oil exploration.
