Adaptive Supramolecular Interactions Govern Redox‐Active Molecules in Aqueous Redox Flow Batteries

Advanced Materials, EarlyView.
Adaptive supramolecular interactions overcome the solubility‐stability trade‐off in aqueous redox flow batteries. Hydrophobic anions disrupt intrinsic π–π stacking to enable high solubility, while redox‐state‐dependent spin pairing and cation coordination dynamically stabilize reactive intermediates during operation.

Biopolymer Modified with Piperazine-2- Carboxylic Acid for Carbon Dioxide Adsorption

Chemical Engineering Transactions, 2013
A new adsorbent biopolymer, piperazine bipolymer (PBP), was successfully modified with a piperazine derivative for CO2 adsorption. The biopolymer was purified by an alkali treatment to obtain 96.43 % degree of deacetylation and used as the reactive ...

Scalable Fabrication of Chemically Stabilized Gelatin Hydrogel Fibers by Thermal Drawing

Advanced Materials Interfaces, EarlyView.
Scalable processing of hydrogel fibers remains a major challenge. By coupling thermal drawing with Maillard chemistry, a transient viscous‐flow window is created that enables continuous fabrication of microstructured gelatin fibers tens of meters long, while continued in situ crosslinking during drawing stabilizes the fibers for physiological ...

Bypass chromatography : design and analysis of an improved strategy for operating batch chromatography processes

, 2012
The possibility to improve the performance of batch chromatographic separations by using so-called bypass method is analyzed for the first time. In bypass chromatography, only a part of the feed is introduced into the column and purified to purity larger

Underground Signals: The Ecological Power of Root Volatiles

Advanced Science, EarlyView.
Root volatiles mediate rhizosphere chemical communication, shaping interactions among plants, microbes, herbivores, and natural enemies. Their production, transport, and perception underpin ecological adaptation, multitrophic interactions, and plant resilience, offering opportunities for sustainable crop protection, resilient agroecosystems, and ...

NMR studies of adsorption processes upon activated carbon [PDF]

, 1998
This thesis is concerned with the adsorption behaviour of adsorbate molecules upon activated carbon. Limitations in bulk gravimetric measurements mean that the mechanism of adsorption for adsorbates upon carbonaceous materials is poorly characterised ...
