3D nanowire networks are fascinating systems for future microelectronic devices. They can be handled like macroscopic objects, while exhibiting properties of nanoscale materials. Here, the fabrication free-standing bismuth with well-controlled and systematically adjusted wire diameter interconnectivity is presented. The samples fabricated by pulse electroplating into pores ion track-etched memb...

Although the optical microscope has been the main tool for observations of etched tracks in solid state nuclear track detectors for many years, there has been relatively little investigation about the optical characteristics of these tracks. This chapter describes the application of the ray tracing method to light propagation through these etched tracks. The method is shown to be able to reprod...

Traditional Transwell inserts with track-etched 10 ?m thick polymer membranes have been intensively used for studying cellular barriers. However, their thickness hampers direct cell-cell interaction between the adjacent cells which has shown to critically influence barrier formation. Therefore, here effect of reduced distance by using fivefold thinner (2 ?m) optically transparent polydimethylsi...

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...

The location, nature, and size distribution of uranium-rich grains in sediment layers can be identified by sunbursts of etched particle tracks if each sample is pressed against a track detector, next irradiated with thermal neutrons, and the detectors then chemically etched to reveal fission tracks. The total track abundance from the sample is a measure of the 235U content; hence, if the bulk u...
