Membrane separation processes are emerging in various water treatment and gas separation applications. Polymeric membranes offer many advantages, as polymers are easy to handle and modify, are flexible, and their upscaling from a laboratory-level to pilot and industrial-scale installations is highly feasible. Nevertheless, obstacles hindering further growth of polymeric membrane technology, still exist. A trade-off between membrane permeability and selectivity with an upper limit known as Robeson boundary, and physical aging, or, more generally, membrane stability, are the key challenges for polymeric gas separation membranes. On the other hand, for water desalination using polymeric, i.e. aromatic polyamide thin film composite (TFC) membranes, low water permeance and insufficient salt rejection, as well as membrane fouling and poor tolerance to chlorine, are the main challenges.
One strategy to overcome these challenges in both gas separation and desalination applications is to incorporate a second phase, either in the form of nanoparticles or by including low molecular substances. In the case of nanocomposite gas separation membranes, deviation of permeability, solubility, and diffusivity from simple mixing rules have been reported. These observations may have been caused as a consequence of a variety of effects, ranging from higher free volumes, variations in solubility, or a different microstructure of the matrix. In the case of water desalination, incorporation of hydrophilic nanoparticles in the selective polyamide layer is a strategy used to enhance the performance and physiochemical properties of the resulting thin film nanocomposite (TFN) membranes.
This Special Issue focuses on recent advances in the development of novel nanoparticles, and the preparation and characterization of the resulting nanocomposite membranes for gas separation and water treatment applications.
Authors are, therefore, invited to submit their latest results. Original papers, communications and reviews are welcome.

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 papers will be 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 1800 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.
