Molecular dynamics simulations allow the study of Ostwald ripening under diverse conditions using a limited number of parameters. The proposed molecular dynamics simulation approaches are able to reproduce the behavior observed experimentally and by other simulations, and reveal that this enhancement is due...
A刊发了新加坡国立大学曾华淳教授课题组撰写的题为Synthesis of complex nanomaterials via Ostwald ripening的综述,很详细的介绍了生成空心结构的著名机理---Ostwald熟化机理在合成复杂结构中的最新研究进展,文章9页,引文80篇。 In recent years, nanostructured materials with interior cavities and surface porosity have...
An etching-intralayered Ostwald ripening process is proposed, which leads to the formation of a β-Ni(OH)2 ultrathin nanomesh with abundant and uniformly distributed nanopores of 3-4 nm. The nanomesh catalyst exhibits outstanding oxygen evolution reaction performance, with high catalytic current den...
对于空心结构生长机理的研究,最重要的两种机理是柯根达尔效应(Kirkendall Effect)和奥斯特瓦尔德熟化机理(Ostwald Ripening),前者主要特点是生长前后为异相,而后者为相同物相的溶解-再结晶过程。附件为介绍这两个生长机理的经典文献。分别为: 1. Formation of Hollow Nanocrystals Through the Nanoscale Kirkendall Effect ...
It has been generally accepted that crystal shrinkage during Ostwald ripening can be understood simply as a reverse process of crystal growth, and as a res... SY Chung,YM Kim,SY Choi,... - 《Acs Nano》 被引量: 4发表: 2015年
3.2.8.2 Ostwald Ripening Ostwald ripening177 is an insidious process by which smaller droplets disappear and larger droplets grow by the process of the oil molecules diffusing through the continuous phase from the small droplets. The driver for this activity is the fact that the Laplace pressure in...
The paper describes a theoretical study of the Ostwald ripening of two-dimensional small-size precipitates of a newly formed phase at the grain boundary of finite thickness, taking into account the diffusion of impurity atoms from the grain interior to the grain boundary. The precipitate growth is...
and the phenomenon has come to bear his name. The basic theory of particle coarsening was developed by Greenwood2, Lifshitz and Slyozov3,4, and Wagner5. For brevity we shall refer to it as the LSW theory. Reviews on Ostwald Ripening have been published e. g. by Greenwood6, by Che-Yu...
