A computational model for light propagation through an etched alpha-particle track was described. Four different cases for light ray propagation through the etched track were studied in detail. The track profile, optical appearance and distribution of scattered light were given for three typical types of etched tracks. These laid the foundation for future automatic determination of properties o...

There is increasing evidence that surface curvature at a near-cell-scale influences cell behaviour. Epithelial or endothelial cells lining small acinar tubular body lumens, as those of the alveoli blood vessels, experience such highly curved surfaces. In contrast, most commonly used culture substrates for in vitro modelling these human tissue barriers, ion track-etched membranes, offer only fla...

650 ?m thick PADC foils are exposed to 7 GeV Silicon and 17.48 Nickel accelerated ions at particle fluence of about 1000 cm?2. The relativistic passed through the entire thickness created latent tracks that were etched sequentially under strong etching conditions (NaOH + ethanol). For each time sequence, track profiles found by carefully polishing detector edge, then imaged in order measure the...

This study investigates the surface modification of polyethylene terephthalate track-etched membranes by planar magnetron sputtering titanium and dioxide thin films to improve its hydrophilicity photocatalytic activity. After cold plasma treatment enhanced adhesion, Ti were deposited TiO2 reactive in an Ar-O2 gas atmosphere. The morphology was characterised using atomic force microscopy scannin...

The suitability of three vapor deposition techniques for pore size modification was evaluated using polycarbonate track etched membranes as model supports. A feature scale model was employed to predict the pore geometry after modification and the resulting pure water flux. Physical vapor deposition (PVD) and pulsed plasma-enhanced chemical vapor deposition (PECVD), naturally, form asymmetric na...

Recently, Matiullah et al. described the use of NaOH/ethanol as an etchant for the CR-39 detector, and have determined the corresponding bulk and track etch properties from the track diameter method. In the present work, the bulk and track etch properties of CR39 in NaOH/ethanol were derived from direct measurements. The bulk etch rate has been found to increase with the molarity of NaOH/ ethan...

Background: High and intermediate energy protons are not able to form a track in a solid state nuclear track detector (SSNTD) directly. However, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a SSNTD. Materials and Methods: The protons with primary energies of 9.6 and 30 MeV available at the cyclotron accelerator with corresponding lo...
