Special Issue Information

Dear Colleagues,

The 2nd International Conference on Mineral Engineering and Materials Science (iCMEMS2022, http://www.icmems.net.au) will be held in a hybrid format (in person and virtually) in Sydney, Australia, on 27–30 November 2022. The conference is to provide a platform for academics, researchers, graduates, and industry professionals to present and share their latest research and practice in the broad fields of mineral engineering, process metallurgy, material science and engineering, and particle science and technology.

We invite conference participants of iCMEMS2022 as well as other researchers to submit your high-quality manuscripts to this Special Issue of Materials: Advances in Materials, Chemical and Computational Science. The topics include but are not limited to the following:

Advanced materials characterization
Biomaterials
Energy materials
Functional materials
Materials modeling and simulation
Mineral materials
Nanomaterials
Particle science and technology
Process metallurgy
Solid waste and materials recycling
Sustainable building and construction materials

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. Materials is an international peer-reviewed open access semimonthly 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 2300 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.

Abstract

As one of the most widely used inorganic fine powder fillers, calcium carbonate is cheap. However, considering its poor light transmittance, it is not suitable to be added to resin matrix composites that require high light transmittance. Aluminum hydroxide has good light transmission and flame retardancy, but it is more expensive than calcium carbonate. CaCO₃/Al(OH)₃ composites with a core-shell structure that showed a trend toward the performance of aluminum hydroxide not only improved the surface properties of CaCO₃, but also increased the added value of CaCO₃. In the present paper, CaCO₃/Al(OH)₃ composites were successfully prepared in sodium aluminate solution via heterogeneous nucleation. Four types of calcium sources, including calcite-type precipitated calcium carbonate, vaterite-type precipitated calcium carbonate, ground calcium carbonate with two different particle sizes as the precursors and supersaturated sodium aluminate solution as the substrate, have been deeply investigated in terms of their influence on the preparation of CaCO₃/Al(OH)₃ composites. Results showed that the calcium carbonate precursor greatly affected the formation of CaCO₃/Al(OH)₃ composites. Both the precipitated calcium carbonate and the small particle ground calcium carbonate are likely to undergo anti-causticization and a complexation reaction with it to generate 3CaO·Al₂O₃·6H₂O and 3CaO·Al₂O₃·CaCO₃·11H₂O, which go against the coating of calcium carbonate with aluminum hydroxide. Within the experimental range, the use of ground calcium carbonate with a particle size of 400–500 mesh is more suitable as a precursor for the preparation of core-shell CaCO₃/Al(OH)₃ composites.

Abstract

To address the environmental pollution caused by nitrogen oxides, V₂O₅-WO₃/TiO₂ is widely used as a catalyst based on selective catalytic reduction (SCR) technology. However, spent SCR catalysts pose a potential hazard to the environment due to the presence of heavy metals. This problem continues to plague countries with predominantly thermal power generation, and landfills as the dominant disposal method wastes significant metal resources. Previous research into the recovery of these metal resources has received considerable attention. Here, we summarise the methods of recovery and find that research trends are beginning to move towards improving the added value of recovered products. One very promising application is photocatalysts; however, the atomic efficiency of current methods is not satisfactory. Therefore, this review first focuses on the regeneration of spent SCR catalysts and the processes used for elemental extraction to clarify what forms of V, W and Ti can be obtained from existing processes. This is followed by providing directions for the conversion of spent SCR catalysts into photocatalysts with improvements based on such processes. From a different perspective, this also provides a new resource for photocatalysts and is expected to significantly reduce the cost of photocatalyst production. Full article
