Special Issue Information

Dear Colleague,

Plasmas are ionized gases formed by fast free electrons from molecules and atoms after external energy sources have been applied to a gaseous or liquid medium. Once derived, the charged particles (electrons and ions) are accelerated and capable of ionizing, exciting, and dissociating surrounding gas molecules and atoms. In such a way, plasma becomes a reservoir of chemically reactive species that can interact mutually or with surrounding solids and liquids under different conditions of input energy, power, pressure, medium composition, etc., thereby forming stoichiometric and/or non-stoichiometric particles and composite (nano)materials with various morphologies and properties. 

The field of laser development has bloomed over the few last decades, producing versatile lasers for various purposes, including material synthesis and modification, precise measuring techniques, and methods for the analysis of synthesized materials and their overall physicochemical properties.

This Special Issue focuses primarily on cutting-edge topics related to inorganic synthesis, fabrication, modification, degradation, and analysis under laser-supported plasma conditions. However, the submission of original articles related to inorganic synthesis and analyses in current-generated plasmas in combination with laser plasmas or laser-based measurements is also encouraged.

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. Inorganics 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 2700 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.

We have developed an easy route to prepare (nano-ZrO2,nano-ZrCx)@C composites with varying ZrO2/ZrCx content. The process consists of preparing a zirconium-loaded, iminodiacetate-functionalized styrene-divinylbenzene (STY-DVB) copolymer, and its subsequent carbonization in a tube furnace and/or a thermal plasma reactor. Depending on the zirconium salt used (zirconyl chloride, zirconyl nitrate or zirconium (IV) sulfate) in the Zr loading, the Zr-loaded resins resulted in ZrO2@C pre-pyrolizates with C to Zr molar ratios of 5.8, 6.8 and 6.60. This carbon surplus is sufficient for the partial or even complete reduction of ZrO2 into ZrC0.58 at 1400 °C. The reaction products also contain 5 to 55 mass% residual free carbon. The plasma processing of the ZrO2@C composite formed at 1000 °C in a tube furnace led to ZrC0.94@C composites. The transformation of amorphous carbon content during the plasma treatment strongly depended on the atmosphere (He or H2) in the reactor and the anion type of the Zr salt. In the presence of He, amorphous carbon could be completely transformed into graphite. In the presence of H2, amorphous carbon and graphite were found at roughly the same ratio. No ZrO2 could be detected in the plasma-treated samples, whilst different ZrO2 polymorphs were found in the samples prepared in the tube furnace, depending on the synthesis conditions. Full article
