Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime

Advanced Functional Materials, EarlyView.
A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.

THERMODYNAMICS OF EQUILIBRIUM AND STABILITY

Acta Physica Sinica, 1948
The dependence of the entropy of a homogeneous system on the composition is investigated with the help of a reversible adiabatic process which allows the change of composition by means of a semipermeable wall. The conditions of equilibrinm for phase transition and for homogeneous chemical reaction are derived in a new way. Next the criterion of minimum

Advancing the Co‐Based Anode Catalysts Using Ionomers in Pure‐Water Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
The role of ionomers is investigated in advancing cobalt‐based oxygen evolution catalysts in pure‐water anion exchange membrane electrolysers. Using in situ electrochemical analysis, ex situ material characterization, and membrane potential sensing, it is observed surface reconstruction at high currents and mitigated it via ionomer coating, achieving ...

Moisture sorption isotherms of sunflower seeds: Thermodynamic analysis

Ciência e Agrotecnologia
The study of the thermodynamic properties provides the knowledge of the sorbent affinity by the water and the spontaneity of the sorption process, important to design drying equipment and to predict hygroscopic behavior during storage. This work aimed to

Fluorophobic Effect Enables Selective Detection of PFAS in Water with Electrolyte‐Gated Organic Transistors

Advanced Functional Materials, EarlyView.
PerFluoroAlkyl Substances (PFAS) are responsible of major and persistent environmental pollution worldwide. This work demonstrates an ultra‐sensitive sensor for PFAS based on an organic transistor whose gate is functionalized with a binary self‐assembled monolayer containing a perfluorinated molecule.

Highly Active Air Electrode with Enhanced Proton Conduction via Isovalent Doping in a Layered Perovskite for Reversible Protonic Ceramic Cells

Advanced Functional Materials, EarlyView.
A Ni‐doped PBSCN20 air electrode is proposed as a promising air electrode material for reversible protonic ceramic cells. An isovalent doping significantly facilitates oxygen vacancy formation and proton uptake while simultaneously reducing the energy barrier for proton migration.

Multidimensional thermodynamic potential for descriptions of ultrathin lubricant film melting between two atomically smooth surfaces

Condensed Matter Physics, 2011
The thermodynamic model of ultrathin lubricant film melting, confined between two atomically-flat solid surfaces, is built using the Landau phase transition approach. Non-equilibrium entropy is introduced describing the part of thermal motion conditioned
