Special Issue Information

Dear Colleagues,
 
Nowadays, membrane techniques are used not only as industrial solutions for water or wastewater treatment but also as potential technologies for the separation of gas and liquid mixtures and the valorization of residues in the circular economy. Resources such as metals, REEs (rare earth elements), salts, fertilizers, bio compounds, energy, etc., can be recovered from various wastes using membrane technologies.

The aim of this Special Issue, entitled "Membranes in Gas and Liquid Mixture Separation and Resource Recovery", is to promote membrane technologies as innovative, environmentally friendly, and inexpensive technologies for gas separation, liquid mixture separation, water treatment, wastewater treatment, and multi-resource recovery. Therefore, the scope of this Special Issue includes, but is not limited to, new approaches in membrane design and synthesis, novel membrane materials, transport phenomena/mechanisms, mathematical modeling, module, and membrane reactor design, novel applications, and industrial exploitation of membrane techniques in gas separation, desalination, water and wastewater treatment, biomedical and tissue engineering, drug delivery, recovery of any type of resources, etc. Authors are welcome to submit original research papers, communications, and review articles. We are very much looking forward to your outstanding contribution to this Special Issue.

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. Membranes 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.

Novel inorganic–organic hybrid membranes Fe@MWCNT/PPO or Fe@MWCNT-OH/SPPO (with a new type of CNTs characterized by increased iron content 5.80 wt%) were synthesized for CO2 separation. The introduction of nanofillers into the polymer matrix has significantly improved the hybrid membrane’s gas transport (D, P, S, and αCO2/N2), magnetic, thermal, and mechanical parameters. It was found that magnetic casting has improved the alignment and dispersion of Fe@MWCNTs. At the same time, CNTs and polymer chemical modification enhanced interphase compatibility and the membrane’s CO2 separation efficiency. The thermo-oxidative stability and mechanical and magnetic parameters of composites were improved by increasing new CNTs loading. Cherazi’s model turned out to be suitable for describing the CO2 transport through analyzed hybrid membranes. Full article
