Phase separation and large deviations of lattice active matter

, 2017
Off-lattice active Brownian particles form clusters and undergo phase separation even in the absence of attractions or velocity-alignment mechanisms. Arguments that explain this phenomenon appeal only to the ability of particles to move persistently in a

Interplay of phase boundary anisotropy and electro-autocatalytic surface reactions on the lithium intercalation dynamics in Li$_X$FePO$_4$ platelet-like nanoparticles

, 2018
Experiments on single crystal Li$_X$FePO$_4$ (LFP) nanoparticles indicate rich nonequilibrium phase behavior, such as suppression of phase separation at high lithiation rates, striped patterns of coherent phase boundaries, nucleation by binarysolid ...

Chemotactic Motility-Induced Phase Separation

Physical Review Letters, 2023
Collectives of actively-moving particles can spontaneously separate into dilute and dense phases -- a fascinating phenomenon known as motility-induced phase separation (MIPS). MIPS is well-studied for randomly-moving particles with no directional bias. However, many forms of active matter exhibit collective chemotaxis, directed motion along a chemical ...

Phase Separation Based on U(1) Slave-boson Functional Integral Approach to the t-J Model

, 1999
We investigate the phase diagram of phase separation for the hole-doped two dimensional system of antiferromagnetically correlated electrons based on the U(1) slave-boson functional integral approach to the t-J model.

Spin-state transition and phase separation in multi-orbital Hubbard model [PDF]

, 2009
We study spin-state transition and phase separation involving this transition based on the milti-orbital Hubbard model. Multiple spin states are realized by changing the energy separation between the two orbitals and the on-site Hund coupling.

Hollow Fiber–Supported ZIF-8@GO Reinforced Sol–Gel for Preconcentration of Paraquat Before Determination by UV-Vis Spectrophotometry

Journal of Analytical Methods in Chemistry
A novel, sensitive, and efficient method was developed for the determination of paraquat in soil samples, centered on solid-phase microextraction using hollow fiber–supported ZIF-8@GO reinforced sol–gel combined with UV-Vis spectrophotometry at 257 nm ...

Ongoing phase separation inside hollow fiber membranes via non-solvent induced phase separation

Journal of Membrane Science Letters
This study investigates the critical influence of residual solvent on pore evolution during the non-solvent induced phase separation (NIPS) process. Employing a comprehensive multi-technique approach, including FT-IR spectroscopy, UV absorbance, contact ...
