Sonocrystallization as an Efficient Way to Control the Size, Morphology, and Purity of Coordination Compound Microcrystallites: Application to a Single-Chain Magnet.
Quentin Evrard,Felix Houard,Carole Daiguebonne,Guillaume Calvez,Yan Suffren,Olivier Guillou,Matteo Mannini,Kevin Bernot,Kevin Bernot +8 more
TL;DR: It is proposed that sonocrystallization, which is already used on organic or MOF compounds, can be applied to (magnetic) coordination compounds to readily afford bulk powders for characterization or shaping techniques that require pure, morphology- and crystallite-size-controlled powder samples.

Flow properties of CO2 sorbent powders modified with nanosilica
TL;DR: In this paper, the flow behavior of a CO2 sorbent precursor (natural limestone) and a modified carbon dioxide (CO2) precursor, obtained by dry mixing the natural limestone and a silica nanostructured powder, is investigated.

Modeling particle-size distribution dynamics in a shear-induced breakage process with an improved breakage kernel: Importance of the internal bonds
TL;DR: In this article, an improved aggregate breakage kernel was developed that accounts for the effects of both the internal bonding forces between particles within an aggregate and the fluid shear stress exerted on the aggregate.

Stability and Biological Responses of Zinc Oxide Metalworking Nanofluids (ZnO MWnF™) using Dynamic Light Scattering and Zebrafish Assays
TL;DR: Zinc oxide nanoparticles (ZnO NPs) have demonstrated the ability to improve lubrication and thermal conductivity and are promising metalworking lubricant and coolant additives due to their low cost as discussed by the authors.

Modelling the kinetics of aggregate breakage using improved breakage kernel.
Xiao Feng,Li Xiao-yan +1 more
TL;DR: An improved breakage kernel was developed and the sectional numerical technique can be well simulated by the change in particle size distribution (PSD), showing that the fractal dimension plays a significant role in the breakage process.

Collapse of an initially spherical vapour cavity in the neighbourhood of a solid boundary
TL;DR: In this paper, a numerical method was proposed to solve the problem of balloon bubble collapse near a plane solid wall, using finite time steps and an iterative technique for applying the boundary conditions at infinity directly to the liquid at a finite distance from the free surface.

Cavitation produced by Ultrasonics
B E Noltingk,E A Neppiras +1 more
TL;DR: In this article, the problem of cavitation produced by ultrasonic vibration is examined theoretically, and it is predicted that all cavitation phenomena will diminish and finally disappear as the frequency is raised.

Agglomerate and Particle Size Effects on Sintering Yttria‐Stabilized Zirconia
TL;DR: In this article, the initial-, intermediate-, and final-stage sintering of fine crystallite yttria-stabilized zirconia was studied, and it was found that agglomerates limit attainable green density, interfere with the development of microstructure, impede initial-stage Sintering kinetics, and limit the potential benefit of the fine crystallites on final stage sinterings.
