Article Abstract

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 region at a zero shear rate. We present experimental evidence that spinodal decomposition is driven by orientational diffusion, in accordance with a very recent theory.

Modelling of formic acid production using solventless trialkylamine reduction strategies.

Solventless fed-batch experiments at elevated pressures were performed to gain insights into the performance of triethylamine as an extraction base during the direct hydrogenation of CO to formic acid. No formic acid was observed in the bulk liquid after several hours of reaction using an Au/TiO catalyst. Analysis on the spent catalyst revealed significant formic acid build-up within the catalyst pores.

This study investigates the influence of Cu addition on the nanostructural evolution and mechanical performance of a heavily drawn non-equiatomic CoCuFeMnNi high-entropy alloy (HEA) wire. Through systematic microstructural and compositional analysis, we examine how Cu constituent affects phase separation behavior and promotes deformation-induced nano-twinning in another phase counterpart. The designed HEA wire exhibits an elongated ultrafine dual face-centered cubic (fcc) lamella structure (i.

Two-temperature induced phase separation (2-TIPS) is a phenomenon observed in mixtures of active and passive particles modeled by scalar activity where the temperature of the particle is proportional to its activity. The binary mixture of "hot" and "cold" particles phase separates when the relative temperature difference between hot and cold particles, defined as activity χ, exceeds a density-dependent critical value. The study of kinetics in 2-TIPS, a nonequilibrium phase separation, is of fundamental importance in statistical physics.

Phyllotactic patterns, where elements such as leaves, seeds, or droplets arrange along alternate spirals, are fascinating examples of complex structures encountered in nature. In botany, their symmetries develop when a new primordium periodically grows in the largest gap left between the previous one and the apex. Experiments using ferrofluid droplets have shown that phyllotactic patterns can also spontaneously form when identical elements repulsing each other are periodically released at a given distance from an injection center and are advected radially at a constant speed.

Spinodal decomposition enables coherent plasmonic metal/semiconductor heterostructure for full spectrum photocatalysis.

Nanoscale metal/semiconductor heterostructures are critical components for a variety of light energy conversion applications. Herein, with plasmonic hafnium nitride (HfN) as a model system, we show that spinodal decomposition can be exploited as a unique means to produce the lattice-coherent metal/semiconductor heterostructure between HfN and its native oxynitride semiconductor-HfON. Atomic-resolution electron microscopy imaging provides direct visualization of the complete lattice coherency over the interface region with precisely controlled spatial modulation.
