Deciphering Intricacies in Directional CO2 Conversion From Electrolysis to CO2 Batteries

Advanced Energy Materials, EarlyView.
This review will delve into the inherent connections and distinctions of CO2‐directed conversion in ECO2RR and CO2 batteries, in terms of product types, catalyst selection, catalytic mechanisms, and electrochemical performances, while proposing a benchmarking framework for the evaluation of CO2 batteries and innovative CO2 battery configurations for ...

Asymmetric Multi‐Site Ion Exchange in Porous Carbon Electrodes

Advanced Energy Materials, EarlyView.
A lognormal‐distribution 2D EXSY NMR framework uncovers the full spectrum of ion dynamics in hierarchical porous carbons, bridging fast surface exchange and confined in‐pore transport—establishing structure–transport relationships for next‐generation energy storage, gas storage, and ion removal materials.

Field and flow programming in frit-inlet asymmetrical flow field-flow fractionation

Journal of Chromatography A, 2002
The separation of wide molecular mass (Mr) ranges of macromolecules using frit inlet asymmetrical flow field-flow fractionation (FI-AFlFFF) has been improved by implementing a combination of field and flow programming. In this first implementation, field strength (governed by the cross flow-rate through the membrane-covered accumulation wall) is ...

Asymmetric Flow Field-Flow Fractionation in the Field of Nanomedicine

Analytical Chemistry, 2014
Asymmetric flow field-flow fractionation (AF4) is a widely used and versatile technique in the family of field-flow fractionations, indicated by a rapidly increasing number of publications. It represents a gentle separation and characterization method, where nonspecific interactions are reduced to a minimum, allows a broad separation range from several

Fractionation of Humic Substances by Asymmetrical Flow Field-Flow Fractionation

Chromatographia, 2005
Asymmetrical flow field-flow fractionation was used to investigate the effects of pH and ionic strength of the buffer, and the binding of polyaromatic hydrocarbons (PAHs) on the particle sizes of humic substances (HSs). Particle sizes were greater when HSs were present in acidic medium with phosphate buffer than when they were present in alkaline ...

Analysis of plant ribosomes with asymmetric flow field-flow fractionation

Analytical and Bioanalytical Chemistry, 2013
Ribosome profiling is a technique used to separate ribosomal subunits, 80S ribosomes (monosomes), and polyribosomes (polysomes) from other RNA-protein complexes. It is traditionally performed in sucrose gradients. In this study, we used asymmetric flow field-flow fractionation (AsFlFFF) to characterize ribosome profiles of Nicotiana benthamiana plants.

The use of asymmetrical flow field-flow fractionation in pharmaceutics and biopharmaceutics

European Journal of Pharmaceutics and Biopharmaceutics, 2004
Field-flow fractionation (FFF) is a family of flexible analytical fractionating techniques which have the advantage that the separation of analytes is achieved, solely through the interaction of the sample with an external, perpendicular physical field, rather than by the interaction with a stationary phase.

Optimisation of asymmetrical flow field flow fractionation for environmental nanoparticles separation

Journal of Chromatography A, 2008
The fractionation of natural nanoparticles by Asymmetrical Flow Field Flow Fractionation (As-Fl-FFF) was optimised by considering the following operating conditions: ionic strength, surfactant concentration and crossflow rate. The method performances such as fractionation recovery and fractionation efficiency were evaluated on a stable solution of ...
