Modelling the coupled mercury-halogen-ozone cycle in the central Arctic during spring

Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot, Jenny Thomas

Near-surface mercury and ozone depletion events occur in the lowest part of the atmosphere during Arctic spring. Mercury depletion is the first step in a process that transforms long-lived elemental mercury to more reactive forms within the Arctic that are ...

A data-science approach to predict the heat capacity of nanoporous materials

Berend Smit, Susana Garcia Lopez, Elias Moubarak, Balázs Álmos Novotny, Seyedmohamad Moosavi, Daniele Ongari, Mehrdad Asgari, Andres Adolfo Ortega Guerrero, Özge Kadioglu

The heat capacity of a material is a fundamental property of great practical importance. For example, in a carbon capture process, the heat required to regenerate a solid sorbent is directly related to the heat capacity of the material. However, for most m ...

HCN production from formaldehyde during the selective catalytic reduction of NOx with NH3 over V2O5/WO3-TiO2

Davide Ferri, Oliver Kröcher, Rob Jeremiah G. Nuguid

Raw exhaust gases may contain notable levels of formaldehyde that can negatively impact the efficiency of after -treatment systems. In the selective catalytic reduction (SCR) of NOx over V2O5/WO3-TiO2, formaldehyde was found to react with NH3 to produce HC ...

Nanosecond pulsed laser-processing of CVD diamond

Patrik Willi Hoffmann, Marco Cantoni, Sébastien Equis

This work considers the resulting material structural effects of laser-processing chemical vapor deposited (CVD) diamond. The utilized 532 nm wavelength laser had a pulse duration of 40 ns together with a spot diameter of ca. 40 mu m. The effect of cutting ...

Evaluation of materials for iodine and technetium immobilization through sorption and redox-driven processes

Wendy Lee Queen, Daniel Teav Sun

Radioactive iodine-129 (I-129) and technetium-99 (Tc-9(9)) pose a risk to groundwater due to their long half-lives, toxicity, and high environmental mobility. Based on literature reviewed in Moore et al. (2019) and Pearce et aL (2019), natural and engineer ...

Data-driven design of metal-organic frameworks for wet flue gas CO2 capture

Berend Smit, Susana Garcia Lopez, Kyriakos Stylianou, Seyedmohamad Moosavi, Peter George Boyd, Andrzej Gladysiak, Christopher Patrick Ireland, Arunraj Chidambaram, Enrique Garcia Diez

Limiting the increase of CO2 in the atmosphere is one of the largest challenges of our generation(1). Because carbon capture and storage is one of the few viable technologies that can mitigate current CO2 emissions(2), much effort is focused on developing ...
