Special Issue Information
Dear Colleagues,
Two-dimensional transition metal carbides and nitrides (MXenes) have attracted significant research attention for various applications including electrochemical energy storage, electronics, optics, catalysis, electromagnetic interference shielding, sensing, water treatment, and biomedicine. The rich surface chemistry of MXenes has highlighted their potentials based on unique property combinations, such as hydrophilicity and metallic conductivity. Many MXene studies have been related to the Ti3AlC2 MAX phase and corresponding MXenes: Ti3C2Tx (Tx = O, OH, F, etc.) from wet-etching using acidic solution and Ti3C2Cl2 (or any other halogens) from Lewis-acid molten salt (LAMS) etching. There are nominally 110 different MAX phases, excluding solid solutions; however, a few Al-based MXenes have been prioritized for study. The change in the A-element in the starting MAX phase will significantly affect their etch chemistry, which may lead to the discovery of new MXenes and surface chemistry. Authors are encouraged to explore relatively less studied MAX phases and acid or molten salt etching methods.
Potential topics for this Special Issue include, but are not limited to, the following:
- Synthesis of MAX phase;
- Selective chemical etching;
- Molten salt etching; surface modification;
- Post-synthesis treatment;
- UV-vis-NIR spectroscopy;
- Raman spectroscopy;
- X-ray diffraction;
- Electrical conductivity;
- Sensing;
- Electrochemistry;
- Electromagnetic interference shielding;
- Solution process;
- Colloidal stability;
- Thermal stability.

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 250 words) can be sent to the Editorial Office for assessment.
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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
