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

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

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, ...

Anion Selection Criteria for Water-in-Salt Electrolytes

Corsin Battaglia, David Reber, Maximilian Becker

Water-in-salt electrolytes have enabled the development of novel high-voltage aqueous lithium-ion batteries. This study explores the reasons why analogous sodium electrolytes have struggled to reach the same level of electrochemical stability. Solution str ...

Enhancing the Signaling of GPCRs via Orthosteric Ions

Horst Vogel, Shuguang Yuan

G protein-coupled receptors play essential roles in cellular processes such as neuronal signaling, vision, olfaction, tasting, and metabolism. As GPCRs are the most important drug targets, understanding their interactions with ligands is of utmost importan ...

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

Paul Joseph Dyson, Andreas Züttel, Loris Giovanni Lombardo, 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 ...

Metal Soap Membranes for Gas Separation

Kumar Varoon Agrawal, Jian Hao, Davide Campi, Deepu Joseph Babu, Qi Liu

Metal soaps or metal alkanoates are metal-organic complexes held together with metal cations and the functional groups of hydrocarbon chains. They can be synthesized at a high yield by simply mixing the metal and organic sources, forming crystalline framew ...

Sodium plating and stripping from Na-β"-alumina ceramics beyond 1000 mA/cm2

Sophia Haussener, Corsin Battaglia, Daniel Alexander Landmann

Dendrite formation limits the cycle life of lithium and sodium metal anodes and remainsa major challenge for their integration into next-generation batteries, even whenreplacing the liquid electrolyte by a solid electrolyte. Voids forming in solid metal an ...

Development of a novel carboxamide-based off-on switch fluorescence sensor: Hg2+, Zn(2+)and Cd2+

Kurt Schenk

Here, the carboxamide ligandN-(thiazole-2-yl) picolinamide (L) was synthesized in an ionic liquid tetrabutylammonium bromide (TBAB) as the benign reaction medium. The sensitivity ofLtowards different metal-ions was investigated, and a comprehensive, logica ...

Ultrafast carbothermal reduction of silica to silicon using a CO2 laser beam

Jaeki Jeong

We report the extraction of silicon via a carbothermal reduction process using a CO2 laser beam as a heat source. The surface of a mixture of silica and carbon black powder became brown after laser beam irradiation for a few tens of seconds, and clear peak ...

Suppressing Crystallization of Water-in-Salt Electrolytes by Asymmetric Anions Enables Low-Temperature Operation of High-Voltage Aqueous Batteries

Corsin Battaglia, David Reber

The discovery of enhanced electrochemical stability for aqueous electrolytes with very high salt concentration has stimulated the development of high-voltage aqueous batteries. We show that a key factor limiting the applicability of these batteries is the ...
