Special Issue Information


Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 300 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Type of Paper: Review
Title: Halide Cluster Catalysis
Authors: S. Nagashima, S. Kamiguchi and T. Chihara *
Affiliation: Graduate School of Science and Engineering, Saitama University, Shimo-Okubo 255, Sakura-ku, Saitama-city, Saitama, 338-8570, Japan; E-Mail: chihara@apc.saitama-u.ac.jp
Abstract: Although metal cluster complexes that have halogen ligands are known 150 years ago, utilization for catalysis has been reported in this past decade. When halide clusters of Group 5 to 7 transition metals are treated in a hydrogen or helium flow at temperatures above 150 °C, catalytic activities developed. Hydroxy group formed by elimination of hydrogen halide from halogen and aqua ligands exhibited weak Brønsted acidity, and uncoordinated metal atoms exhibited platinum-like catalysis. The catalytic activities are stable as high as 400 °C. By taking advantage of these features, some new reactions are developed: one-step synthesis of indenes from benzaldehyde and methylketones, 3-methylbenzofuran from phenol and acetone, and 5 to 7-membered heterocyclic compounds from α,ω-bifunctional alkanes.

Title: Cluster-Assembled Structure and Deformation in Metallic Glass
Authors: W. D. Liu and L. C. Zhang *
Affiliation: School of Mechanical and Manufacturing Engineering, University of New South Wales, NSW 2052 Australia; E-Mail: Liangchi.Zhang@unsw.edu.au
Abstract: Metallic glass (MG) is a newcomer of the metal family, which has a disordered structure and many outstanding properties such as ultrahigh strength, super elasticity, and excellent thermo-plasticity. However, due to the lack of translational periodicity, its cluster-assembled structure and deformation-induced collective atomic rearrangement (dynamic cluster) are long-standing mysteries without sufficient fundamental understanding. In this paper, the authors will review what have been done in the past few decades and aim to unravel the atomic-level structure of MGs and the underlying plastic deformation mechanism. The focus will be on (1) the formation of the cluster-assembled structure through glass transition, (2) structural characterization and theoretical models, (3) plastic event identification and micromechanics, and (4) the correlation between cluster-assembled structure and unique mechanical properties. A number of key questions and outlook in this research area will also be outlined.
