General role of amorphous aggregates in crystal nucleation [PDF]

open access: yes, 2023
There is mounting evidence that crystal nucleation from supersaturated solution involves the formation and reor-ganisation of pre-nucleation clusters contradicting classical nucleation theory.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Effect of phospholipids and bile acids on cholesterol nucleation time and vesicular/micellar cholesterol in gallbladder bile of patients with cholesterol stones [PDF]

open access: yes, 1993
Supersaturation and rapid nucleation of cholesterol in bile are of key importance in the pathogenesis of cholesterol gallstones. While the effects of bile acids and phospholipids on cholesterol saturation of bile have been extensively studied, their ...

Effect of Polyphenols on the Ice-Nucleation Activity of Ultrafine Bubbles

open access: yesNanomaterials, 2023
Ultrafine bubbles (UFBs) in water provide a large amount of gas and a large gas–liquid interfacial area, and can release energy through their collapse. Such features may promote ice nucleation.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Studies on Nucleation from Aqueous Solution [PDF]

open access: yes, 1970
The major part of the present work dealt with adapting the droplet technique to the study of nucleation from solution of some analytically important metal chelates.

Explaining global surface aerosol number concentrations in terms of primary emissions and particle formation [PDF]

open access: yes, 2010
We synthesised observations of total particle number (CN) concentration from 36 sites around the world. We found that annual mean CN concentrations are typically 300–2000 cm -3 in the marine boundary layer and free troposphere (FT) and 1000–10 000 cm -3 ...

Multi-stage heterogeneous bubble nucleation under negative pressures [PDF]

open access: yes, 2023
In this paper, we investigate homogeneous and heterogeneous bubble nucleation processes in systems under tension using molecular dynamics simulations. The maximum pressure (nucleation pressure, $\sigma_{min}$) sustained by the system is used a as measure

An engineered monomer binding-protein for α-synuclein efficiently inhibits the proliferation of amyloid fibrils

open access: yeseLife, 2019
Removing or preventing the formation of [Formula: see text]-synuclein aggregates is a plausible strategy against Parkinson’s disease. To this end, we have engineered the [Formula: see text]-wrapin AS69 to bind monomeric [Formula: see text]-synuclein with
