Concepts of Nucleation in Polymer Crystallization

Crystals, 2021
Nucleation plays a vital role in polymer crystallization, in which chain connectivity and thus the multiple length and time scales make crystal nucleation of polymer chains an interesting but complex subject. Though the topic has been intensively studied

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

Advanced 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

Nucleation in scale-free networks

, 2010
We have studied nucleation dynamics of the Ising model in scale-free networks with degree distribution $P(k)\sim k^{-\gamma}$ by using forward flux sampling method, focusing on how the network topology would influence the nucleation rate and pathway. For

Characterization of Nitinol Produced by Laser Powder Bed Fusion for Mechanical Metamaterial Applications

Advanced Engineering Materials, EarlyView.
Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Energy and Technological Aspects of the Combustion of Ionized Gas-Dispersed Systems

Eurasian Chemico-Technological Journal, 2016
This paper discusses the flame ionization effect on the combustion processes in gaseous suspensions of the dispersed fuels. It is shown that the two-phase flame ionization affects almost all the processes of the fuel conversion – kinetics of the ...

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

Nanomaterials, 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.

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

Advanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

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

eLife, 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
