SAXS data modelling for the characterisation of ion tracks in polymers

Abstract

New SAXS fitting models reveal the detailed morphology of cylindrical ion tracks in polymers composed of a highly damaged core with a gradual transition to the undamaged material.

Surface-charge governed ionic blockade in angstrom-scale latent-track channels

“…1b). However, the effects of irradiation energy, 32,33 UV exposure, 34 and the procedure for removing radiolysis products 27,35 on the channel size are still not clear, not even for their applications. 36 We first investigated the conductance as a function of the salt concentration C, ranging from 1 mM to 3 M KCl at pH 5.0.…”

Highly Rectifying Conical Nanopores in Amorphous SiO2 Membranes for Nanofluidic Osmotic Power Generation and Electroosmotic Pumps

“…Solid-state nanopore membranes can be manufactured in a wide range of materials such as semiconductors, − polymers, − alumina, carbon, graphene, borophene, and MoS 2 with only a single or multiple , pores depending on the material and fabrication technique. One major challenge in current nanopore technology is to combine the high throughput rates that nanopores in ultrathin membranes provide with highly asymmetric transport properties characteristic of long, conical nanopores. , Furthermore, translating the performance of single pores to multipore systems without losing performance has proven to be challenging. , …”
