Atomic-scale apertures represent a novel regime in physics and materials science
Two new studies demonstrate how to fabricate materials with single atom-sized pores that can be used for liquid and gas filtration. This regime of “zero dimensional” pores has a broad range of future applications, from water and gas purification to energy harvesting. The first study, published in ACS Nano (“Stochastic Ionic Transport in Single Atomic Zero-Dimensional Pores”) and led by graduate student Jothi Priyanka Thiruraman, postdoc Paul Masih Das, and professor Marija Drndić, shows the ionic transport properties of these pores, with promise for applications in water purification and desalination as well as for creating artificial pores that mimic ion channels in biology.
