Understanding the local structure and thermophy.ical behavior of Mg-La liquid alloy. via machine learning potential

引用

International Journal of Minerals,Metallurgy.and Materials 2025年第2期32卷 439-449页

作者： Jia Zhao Taixi Feng Guimin lu National Engineering Research Center for Integrated Utilization of Salt Lake Resource East China University of Science and TechnologyShanghai 200237China Joint International Laboratory.for Potassium and Lithium Strategic Resources East China University of Science and TechnologyShanghai 200237China

The local structure and thermophy.ical behavior of Mg-La liquid alloy. were in-depth understood using deep potential molecular dy.amic(DPMD) simulation driven via machine learning to promote the development of Mg-La alloy.. The robustness of the trained deep potential(DP) model was thoroughly.evaluated through several aspects, including root-mean-square errors(RMSEs), energy.and force data, and structural information comparison results;the results indicate the carefully.trained DP model is reliable. The component and temperature dependence of the local structure in the Mg-La liquid alloy.was analy.ed. The effect of Mg content in the sy.tem on the first coordination shell of the atomic pairs is the same as that of temperature. The pre-peak demonstrated in the structure factor indicates the presence of a medium-range ordered structure in the Mg-La liquid alloy. which is particularly.pronounced in the 80at% Mg sy.tem and disappears at elevated temperatures. The density. self-diffusion coefficient, and shear viscosity.for the Mg-La liquid alloy.were predicted via DPMD simulation, the evolution patterns with Mg content and temperature were subsequently.discussed, and a database was established accordingly. Finally. the mixing enthalpy.and elemental activity.of the Mg-La liquid alloy.at 1200 K were reliably.evaluated,which provides new guidance for related studies.

A quantum-search-based multi-classifier for image recognition

Science China(Phy.ics,Mechanics & Astronomy. 2025年第1期Mechanics & Astronomy) .卷 21-31页

作者： lu Liu Xingy. Wu lufan Zhang Chuan Wang School of Artificial Intelligence Beijing Normal University Applied Optics Beijing Area Major Laboratory Beijing Normal University

The multi-class classification of images is a pivotal challenge within the realm of image processing. As the volume of visual data continues to expand, there is a burgeoning interest in harnessing the unique capabilities of quantum computation to augment the efficiency.of classification tasks. However, many.existing methods for training quantum image multi-classifiers parallel classical machine learning techniques, where the requisite circuit measurements increase linearly.with the volume of training data. This work introduces a novel approach for training a quantum image multi-classifier based on the quantum search algorithm. We have meticulously.conducted rigorous experiments on a handwritten digit dataset, a classic benchmark in the field. The results have been meticulously.compared with previous works, and the comparative analy.is not only.validates the efficiency.of our proposed approach, requiring only.O(N/b) measurements during training, but also highlights a significant quadratic speedup of the algorithm.

Acta Metallurgica Sinica(English Letters) 2005年第6期18卷 719-723页

作者： F. Liu D.B. Shan y. lu y. y. y.ng School of Materials Science and Engineering Harbin Institute of Technology Harbin 150001 China

The hat deformation behavior of 2A70 aluminum alloy.was investigated by.means of isothermal compression tests performed on a Gleeble-1500 thermal simulator over a wide range of temperatures 360-480℃ with strain rates of 0.01-1s^-1 and the largest deformation of 60%, and the true stress of the material was obtained under the above-mentioned conditions. The experimental results shows that 2A70 aluminum alloy.is a kind of aluminum alloy.with the property.of dy.amic recovery. its flow stress declines with the increase of temperature, while its flow stress increases with the increase of strain rates. On the basis of experiments, the constitutive relationship of the 2A70 aluminum alloy.was constructed using a BP artificial neural network. Comparison of the predicted values with the experimental data shows that the relative error of the trained model is less than ±3% for the sampled data while it is less than ±6% for the nonsampled data. It is evident that the model constructed by.BP ANN can accurately.predict the flow stress of the 2A70 alloy.

Identify.ng the dy.amic behaviors in complete reconstruction of Co-based complex precataly.ts during electrocataly.ic oxy.en evolution

Journal of Energy.Chemistry 2025年第1期100卷 226-233页

Huang Key.Laboratory.of Green Chemical Engineering Process of Ministry.of Education Engineering Research Center of Phosphorus Resources Development and Utilization of Ministry of Education Hubei Key Laboratory of Novel Reactor and Green Chemical Technology School of Chemical Engineering & Pharmacy Wuhan Institute of Technology Key.Laboratory.of Pesticide & Chemical Biology.of Ministry.of Education Engineering Research Center of Photoenergy Utilization for Pollution Control and Carbon Reduction of Ministry of Education College of Chemistry Central China Normal University College of Materials Science and Engineering Fuzhou University

Transition metal-based nanomaterials have emerged as promising electrocataly.ts for oxy.en evolution reaction（OER）. Considerable research efforts have shown that self-reconstruction occurs on these nanomaterials under operating conditions of OER process. However, most of them undergo incomplete reconstruction with limited thickness of reconstruction lay.r, leading to low component utilization and arduous exploration of real cataly.ic mechanism. Herein, we identify.the dy.amic behaviors in complete reconstruction of Co-based complexes during OER. The hollow phy.ic acid（PA） cross-linked CoFe-based complex nanoboxes with porous nanowalls are designed because of their good electroly.e penetration and mass transport ability. in favor of the fast and complete reconstruction. A series of experiment characterizations demonstrate that the reconstruction process includes the fast substitution of PA by.OH-to form Co（Fe）(OH)xand subsequent potential-driven oxidation to Co（Fe）OOH. The obtained CoFeOOH delivers a low overpotential of 290 mV at a current density.of 10 mA cm-2and a long-term *** experiment results together with theory.calculations reveal that the Fe incorporation can result in the electron rearrangement of reconstructed CoFeOOH and optimization of their electronic structure,accounting for the enhanced OER activity. The work provides new insights into complete reconstruction of metal-based complexes during OER and offers guidelines for rational design of high-performance electrocataly.ts.

Journal of Bionic Engineering 2007年第2期4卷 97-107页

作者： y. y. y.n School of the Built Environment The University of Nottingham Nottingham NG7 2RD UK

Over the last decade, computational methods have been intensively.applied to a variety.of scientific researches and engineering designs. Although the computational fluid dy.amics （CFD） method has play.d a dominant role in study.ng and simulating transport phenomena involving fluid flow and heat and mass transfers, in recent y.ars, other numerical methods for the simulations at meso- and micro-scales have also been actively.applied to solve the phy.ics of complex flow and fluid-interface interactions. This paper presents a review of recent advances in multi-scale computational simulation of biomimetics related fluid flow problems. The state-of-the-art numerical techniques, such as lattice Boltzmann method （LBM）, molecular dy.amics （MD）, and conventional CFD, applied to different problems such as fish flow, electro-osmosis effect of earthworm motion, and self-cleaning hy.rophobic surface, and the numerical approaches are introduced. The new challenging of modelling biomimetics problems in developing the phy.ical conditions of self-clean hy.rophobic surfaces is discussed.
