Liquid Metal and Its Applications

Dear Colleagues,

“Liquid Metal and Its Applications” is a broad title intended to cover some of the recent developments that have contributed most significantly to the increase in the technological applications of these materials. The liquid (or molten) state occurs at widely varying temperature intervals for different metals and alloys. From low-fusion metals, among which the post-transitional elements arise with interest, to refractories fusing above 3000 °C, they all have a high technological interest and are often used or processed in their liquid condition.

Post-transitional metals together with zinc group metals have fascinating properties derived from their low melting point (< 300 °C), making their liquid state accessible for practical applications in many technological fields. Current advances in liquid metal 3D printing are a good example where surface physicochemical properties allow liquid structure configuration.

Understanding liquid metals is essential for many processing techniques, such as infiltration or brazing, leading to metal-based materials with useful properties in many applications, including construction, armament, transportation or electronics. The latest advances in liquid–liquid transitions faced by many metals, nanocontact transport properties, and achievements in amorphous alloy development are still open research fields. Furthermore, failure to understand the structures and properties of liquid metals at high temperatures is crucial in designing physical models to study geophysics or astrophysics planetary systems.

The editors of this volume are convinced that the set of contributions contained therein shows only one apex of the significant progress made in this area recently, and that it can certainly inspire many researchers to go into this discipline of enormous interest.

Manuscript Submission 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. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short 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 thoroughly refereed through a single-blind 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 monthly 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 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
