Isotropic-nematic spinodal decomposition kinetics [PDF]

Physical Review E, 2005
The initial stage of isotropic-nematic spinodal demixing kinetics of suspensions of very long and thin, stiff, repulsive rods is analyzed on the basis of the N-particle Smoluchowski equation. Equations of motion for the reduced probability density function of the position and orientation of a rod are expanded up to second order in spatial gradients and

Entropy‐Driven Innovations: Entropy Stabilized Oxides for High‐Performance Next‐Generation Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This article explores high‐entropy‐stabilized oxides (HEOs) as novel functional materials for addressing critical issues in lithium–sulfur (Li–S) batteries, including lithium polysulfide (LPS) shuttling, inadequate conductivity, and slow redox kinetics.

Asymptotic behaviour of spinodal decomposition

, 1989
We report a numerical study of the asymptotic regime of spinodal decomposition. Specifically, we find (a) that the characteristic pattern size shows a power-law growth with exponent 0.33; and (b) that the effect of noise is asymptotically ...

Nematic-isotropic spinodal decomposition kinetics of rodlike viruses [PDF]

, 2006
We investigate spinodal decomposition kinetics of an initially nematic dispersion of rodlike viruses. Quench experiments are performed from a flow-stabilized homogeneous nematic state at a high shear rate into the two-phase isotropic-nematic coexistence ...

Nitrogen-induced stacking fault energy reduction enables spinodal-decomposition-driven toughening in (Ti,Zr)C ceramics

Journal of Advanced Ceramics
Transition metal carbides exhibit outstanding mechanical properties but suffer from a critical hardness‒toughness trade-off. Spinodal decomposition-mediated phase separation, induced by high-temperature aging, is an effective strategy for enhancing the ...

The role of additives in the film formation kinetics of active layers in organic solar cells: From in situ characterization to mechanistic elucidation

FlexMat, EarlyView.
This review highlights the critical regulatory role of liquid and solid additives in the film formation kinetics of organic solar cells (OSCs) active layer. Real‐time in situ characterization technology techniques (in situ UV‐Vis, PL, GIWAXS, and GISAXS) are utilized to monitor the dynamic solution‐to‐solid transformation, revealing how additives ...

Microwave Effects on Spinodal Decomposition

, 1996
Microstructural differences between microwave and conventionally annealed solid solution TiO2-SnO2 and TiO2-SnO2-(Al2O3)0,02-samples demixed by spinodal decomposition are reported.

Spinodal Theory: A Common Rupturing Mechanism in Spinodal Dewetting and Surface Directed Phase Separation (Some Technological Aspects: Spatial Correlations and the Significance of Dipole-Quadrupole Interaction in Spinodal Dewetting)

Advances in Condensed Matter Physics, 2011
The emerging structures in spinodal dewetting of thin nano films and spinodal decomposition of binary mixtures are found to be similar with certain differences attributed to the nonlinearities inherent in the wetting forces.

Large‐Scale MXene Membrane Fabrication via Nonsolvent Phase Separation

Small Methods, EarlyView.
ABSTRACT Over the past decade, 2D MXenes have garnered tremendous attention for membrane applications owing to their exceptional hydrophilicity, tunable surface chemistry, and antifouling properties. However, translating MXene‐based membranes from laboratory demonstrations to practically relevant manufacturing remains challenging because scalable ...
