freezingmode coupling theoryThis study aims to introduce dynamic scaling and related freezing criterion for alkali metals. The criterion that the ratio of the long-time diffusion and short-time diffusion coefficient has a universal value of DSL/D0 ≈ 0.1 and it is related to the height of the ...
Here we consider the dynamic fracture of metals in solid and liquid states as a non-equilibrium phase transition, consisting in nucleation and growth of spherical vapor cavities. Nucleation rate is obtained from probability of corresponding thermal fluctuations; it accounts the work against surface tens...
Moreover, we also find that quite different liquid metals, such as Si and Mg, also exhibit a similar behavior as Hg, with the only difference being in the time scales involved due to the different masses and interactions. 展开 关键词: Diffusion Mercury (element Liquid metals Molecular ...
Nucleation superheat in liquid metals is an important parameter in the safety analysis of liquid metal cooled reactor. In this paper, the effects of heat flux and velocity were analyzed based on dynamic effects under several typical conditions. The results indicated that according to different ways ...
The leakage factor reciprocal is denoted as follows: (5) f−1=1+T−110T'−11,f−1=1+T10−1T1'−1, T'−11T1'−1 is proportionate to c, the concentration of electron spin (or free radical), alternatively. In this way, equation (3) puts forward (6) A−1∞=(1...
Finally, the periphytic algae samples were divided into two parts: the 200 mL samples were used for the analysis of the chlorophyll a (Chl. a) content, and the remaining 100 mL samples were fixed with Lugol iodine liquid for further quantification and classification using an optical microscope...
The process of a laser melt pool under a steady magnetic field involves various physical processes, such as solid–liquid phase change of the material, heat transfer and convection of the melt pool, surface tension, the free surface motion of the melt pool, etc., which involve the coupling ...

Orbital Free ab-initio Molecular Dynamics simulation study of liquid transition metals lying in the middle of the 3d series is presented. These systems are difficult to handle theoretically due to the fact that, in the middle of the series interplay of bonding and anti bonding states play the ...
A cut-off frequency of 900 kHz was chosen for strain measures to enhance their signal-to-noise ratio, with an 11-points Savitzky-Golay windowing applied to reduce signal spectral leakage [28]. It is worth noticing that in the first few microseconds after the impact the strain gauge signals ...
