Alkalinity Concentration Swing for Direct Air Capture of Carbon Dioxide
Anatoly Rinberg, Andrew M. Bergman, Daniel P. Schrag +1
We describe a new principle - the Alkalinity Concentration Swing (ACS) - for direct air capture of carbon dioxide driven by concentrating an alkaline solution that has been exposed…
Designing steep, sharp patterns on uniformly ion-bombarded surfaces
Joy C. Perkinson, Michael J. Aziz, Michael P. Brenner +1
We propose and experimentally test a method to fabricate patterns of steep, sharp features on surfaces, by exploiting the nonlinear dynamics of uniformly ion bombarded surfaces. We…
Crater functions for compound materials: a route to parameter estimation in coupled-PDE models of ion bombardment
Scott A. Norris, Juha Samela, Matias Vestberg +2
During the ion bombardment of targets containing multiple component species, highly-ordered arrays of nanostructures are sometimes observed. Models incorporating coupled partial di…
Development of Knife-Edge Ridges on Ion-Bombarded Surfaces
Miranda Holmes-Cerfon, Wei Zhou, Andrea L. Bertozzi +2
We demonstrate in both laboratory and numerical experiments that ion bombardment of a modestly sloped surface can create knife-edge like ridges with extremely high slopes. Small pr…
A High Power Density, High Efficiency Hydrogen-Chlorine Regenerative Fuel Cell with a Low Precious Metal Content Catalyst
Brian Huskinson, Jason Rugolo, Sujit K. Mondal +1
We report the performance of a hydrogen-chlorine electrochemical cell with a chlorine electrode employing a low precious metal content alloy oxide electrocatalyst for the chlorine…
Insulator-to-Metal Transition in Selenium-Hyperdoped Silicon: Observation and Origin
Elif Ertekin, Mark T. Winkler, Daniel Recht +4
Hyperdoping has emerged as a promising method for designing semiconductors with unique optical and electronic properties, although such properties currently lack a clear microscopi…
