Iodic acid, sulfuric acid and methanesulfonic acid collected during the Arctic Ocean 2018 expedition

Measurements of iodic acid, sulfuric acid and methanesulfonic acid concentration in the gas phase obtained with a nitrate chemical ionization mass spectrometer (we used an APi-TOF mass spectrometer produced by Tofwerk AG coupled with a Chemical ionization ...

Frequent new particle formation over the high Arctic pack ice by enhanced iodine emissions

Julia Schmale, Andrea Baccarini

In the central Arctic Ocean the formation of clouds and their properties are sensitive to the availability of cloud condensation nuclei (CCN). The vapors responsible for new particle formation (NPF), potentially leading to CCN, have remained unidentified s ...

The effect of sodium hydroxide on Al uptake by calcium silicate hydrates (C S H)

Christian Ludwig, Barbara Lothenbach, Sonya Barzgar, Alessio Di Giacomo, Mohamed Tarik

To reduce the CO2 emissions from cement production, Portland cement (PC) is partially replaced by supplementary cementitious materials (SCM). Reactions of SCM with PC during hydration leads to the formation of CSH with more silicon and aluminum than in PC, ...

Sulfuric acid condensation sink calculated for the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

The condensation sink is a measure of the sulfuric acid lifetime against condensation on preexisting aerosol particles. Dimensionally it is the inverse of a time (reported in per second) and it is calculated starting from the aerosol size distribution. A l ...

Tribocorrosion of a CoCrMo alloy in sulfuric acid - Glycerol mixtures

Stefano Mischler, Shoufan Cao

This work reports on the tribocorrosion properties of a CoCrMo alloy sliding under imposed passive potential against alumina in sulfuric acid-glycerol mixtures exhibiting different viscosities and thus, in principle, lubrication properties. As expected, we ...

Ultrafine particle concentration measured during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

The ultrafine particle (UFP) concentration is the concentration of particles having a diameter between 2.5 and 15 nm, it is reported in terms of particle number per cubic centimeter at a time resolution of 10 minutes. UFP are the smallest particles within ...

Solvent- and Catalyst-Free Carbon Dioxide Capture and Reduction to Formate with Borohydride Ionic Liquid

Paul Joseph Dyson, Loris Giovanni Lombardo, Andreas Züttel, Kun Zhao, Heena Yang

The Cover Feature shows the application of a pyrrolidinium-based ionic liquid with a borohydride anion to simultaneously capture and reduce large amounts of CO2. The ionic liquid cation interacts with CO2, allowing the borohydride to fix and reduce it to t ...

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

Daniel Teav Sun, Wendy Lee Queen

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 ...

Optimization of Lignin Extraction from Pine Wood for Fast Pyrolysis by Using γ-valerolactone-Based Binary Solvent System

Jeremy Luterbacher, Allen Puente-Urbina

Fast pyrolysis of lignin is a promising method to produce aromatic chemicals and fuels. Lignin structure and pyrolysis conditions determine the liquid yield and product selectivity. Extraction of pine wood using γ-valerolactone (GVL) mixed with water in th ...

Hydrothermally Stable Sulfonated Carbons as Solid Acid Catalysts for the Hydrolysis of Lignocellulose

David Ferdinand Scholz

The recycling of homogeneous acids imposes great challenges to the feasibility of lignocellulose hydrolysis processes. Although heterogeneous catalysts would offer a perspective to circumvent these challenges, conventional solid acids are instable under th ...
