AI Article Synopsis
- The study examines the freezing behavior of suspensions, revealing that a layer of compacted particles forms at the solidification front, impacting the freezing process.
- This layer's thickness is influenced by sample depth, highlighting how particle density becomes inhomogeneous during crystallization near solid boundaries.
- A mechanical model links this density inhomogeneity to permeability changes, providing insights that could help in modeling suspensions with varying particle sizes.
Article Abstract
When a suspension freezes, a compacted particle layer builds up at the solidification front with noticeable implications on the freezing process. In a directional solidification experiment of monodisperse suspensions in thin samples, we evidence a link between the thickness of this layer and the sample depth. We attribute it to an inhomogeneity of particle density that is attested by the evidence of crystallization at the plates and of random close packing far from them. A mechanical model based on the resulting modifications of permeability enables us to relate the layer thickness to this inhomogeneity and to select the distribution of particle density that yields the best fit to our data. This distribution involves an influence length of sample plates of about 11 particle diameters. Altogether, these results clarify the implications of boundaries on suspension freezing. They may be useful to model polydisperse suspensions with large particles playing the role of smooth boundaries with respect to small ones.

Heterogeneity is ubiquitous in biological and synthetic active matter systems that are inherently out of equilibrium. Typically, such active mixtures involve not only conservative interactions between the constituents but also nonreciprocal couplings, whose full consequences for the collective behavior still remain elusive. Here, we study a minimal active nonreciprocal mixture with both symmetric isotropic and nonreciprocal polar interactions.

The rapid advancements in 3C electronic devices necessitate an increase in the charge cutoff voltage of LiCoO to unlock a higher energy density that surpasses the currently available levels. However, the structural devastation and electrochemical decay of LiCoO are significantly exacerbated, particularly at ≥4.5 V, due to the stress concentration caused by more severe lattice expansion and shrinkage, coupled with heterogeneous Li intercalation/deintercalation reactions.

Abrupt, local frictional fault failure comprises a displacement that is normally accompanied by acoustic emission (AE)-an impulsive elastic wave broadcast with an amplitude proportional to particle velocity. The aggregate of these displacements is the basic fault motion. In laboratory shear experiments, the examination of a sequence of laboratory earthquakes includes continuous measurements of fault motion and the associated AE that is broadcast.

In this study, thymol-loaded nanoemulsion (THYNE) was incorporated into a mixture of egg white protein and hyaluronic acid to prepare antibacterial biopolymer coatings. The oil phase of the nanoemulsion (NE) was prepared by mixing different mass ratios of thymol and corn oil. NE was formed using ultrasonic emulsification, and the physicochemical properties of the NE were investigated.
