Membrane engineering is a complex field involving the development of the most suitable membrane process for specific purposes and dealing with the design and operation of membrane technologies. This study analyzed 1424 articles on reverse osmosis (RO) membrane engineering from the Scopus database to provide guidance for future studies. The results show that since the first article was published in 1964, the domain has gained popularity, especially since 2009.

Different solvents and mixtures were tested together with different electrospinning parameters and post-treatment types to prepare bead-free fibers without defects. These were successfully obtained using a chloroform/chlorobenzene (40/60 wt.

The core of this technology is the hydrophobic microporous membrane that prevents mass transfer of the liquid while allowing the vapor phase to pass through the membrane's pores. Currently, MD is challenged by its high energy consumption and membrane degradation due to fouling, scaling and wetting.

- Chitosan composite membranes were created using biocompatible metal oxide nanoparticles (TiO, FeO, AlO) at both high and low concentrations, with their saturation points determined for effective integration into the polymeric matrix.
- Characterization techniques like XRD, SEM, and zeta potential revealed that the addition of nanoparticles enhanced the swelling and mechanical properties of the chitosan membranes, particularly with aluminum oxide nanoparticles.
- Swelling tests showed pH-sensitive mechanisms beneficial for drug delivery; aspirin release rates through the membranes varied based on the pH of the simulated gastrointestinal fluids, indicating the membranes can be fine-tuned for specific biomedical applications.
UV irradiation is one of the procedures that has been considered for membrane surface graft polymerization. It is commonly utilized for enhancing the wettability of polyethersulfone (PES) membranes. In this research study, the monomer methacrylic acid (MAA) was used for the UV grafting process of a commercial NF2 PES membrane for the preparation of a forward osmosis (FO) membrane.
