Integration of High‐p, Low‐T CO2 Electrolysis with Pressure Swing Adsorption Purification

Chemie Ingenieur Technik, EarlyView.
We evaluate a high‐p low‐T CO2 electrolysis (LTCE) cell with a pressure swing adsorption (PSA) to compare cascade vs. recycle operation. Although a cascade yields high CO selectivity but limited yield, a full recycle achieves near‐quantitative CO production, highlighting gas recycling as essential for LTCE/PSA systems.

Modelling, dialogism and the functional cycle: biosemiotic and philosophical insights

Sign Systems Studies, 2013
Charles Peirce, Mikhail Bakhtin and Thomas Sebeok all develop original research itineraries around the sign and, despite terminological differences, can be related with reference to the concept of dialogism and modelling. Jakob von Uexküll's biosemiosic "

Vergleichende Untersuchung der Eigenschaften recycelter Kohlenstofffasern Comparative investigation of the properties of recycled carbon fibers

Chemie Ingenieur Technik, EarlyView.
Die Akzeptanz recycelter Kohlenstofffasern in der Industrie erfordert eine hohe und standardisierte Faserqualität. In diesem Artikel werden mechanische Eigenschaften sowie die Oberflächenqualität neuer und recycelter Kohlenstofffasern ermittelt und verglichen, um Optimierungspotentiale für das CFK‐Recycling abzuleiten.

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Uexküll's Kompositionslehre and Leopold's "land ethic" in dialogue. On the concept of meaning

Sign Systems Studies, 2013
Uexküll's famous umwelt theory, which is simultaneously a theory of meaning, remains almost unknown in American environmental thought. The purpose of this article is to create a dialogue between the umwelt theory – a source of inspiration for ...

User‐Relevant Climate Indices and Associated Uncertainties From Transient Convection‐Permitting Climate Model Projections

International Journal of Climatology, EarlyView.
A transient ensemble of convection‐permitting climate simulations is used to compute bias‐corrected user‐relevant climate indices for Germany under recent and future climate conditions, both considering high spatial resolution and uncertainty estimations. For high temperature indices, a clear increase is observed, for example, for hot days and tropical
