“…Even though the individual contributions to tetramer stability still stay elusive, the here discovered correlation of the thermal denaturation temperatures for four AQ(G)Ps with the interaction free energies calculated by PDBePISA imply the crucial role of hydrophobic interactions for the stability of the AQ(G)P fold. AQ(G)Ps are seen as potential building blocks of next generation filter membranes (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28). Furthermore, they are treated as the "holy grail" of native water conducting pores, due to their superior performance in respect to their high permeability and great selectivity.…”

“…To reach this goal, it is important to explore the underlying molecular mechanisms as well as the inter-related pathways and signaling networks through which AQ(G)Ps induce drought tolerance (16). Additionally, (iii) due to their structural stability and easy handling, AQPs are candidates for building blocks of next generation filter membranes (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28) and are already used as a benchmark for newly designed artificial water channels in terms of permeability and selectivity (29). Thus, concepts of solute and solvent flux through narrow membrane channels can be directly transferred to this challenging and emerging field of material science (30)(31)(32)(33)(34)(35)(36)(37) and used to optimize their performance.…”

Evolution turned aquaporins (AQPs) into the most efficient facilitators of passive water flow through cell membranes at no expense of solute discrimination. In spite of a plethora of solved AQP structures, many structural details remain hidden. Here, by combining extensive sequence- and structural-based analysis of a unique set of 20 non-redundant high-resolution structures and molecular dynamics simulations of 4 representatives, we identify key aspects of AQP stability, gating, selectivity, pore geometry and oligomerization, with a potential impact on channel functionality. We challenge the general view of AQPs possessing a continuous open water pore and depict that AQPs selectivity is not exclusively shaped by pore lining residues but also by the relative arrangement of transmembrane helices. Moreover, our analysis reveals that hydrophobic interactions constitute the main determinant of protein thermal stability. Finally, we establish a novel numbering scheme of the conserved AQP scaffold facilitating direct comparison and prediction of potential structural effects of e.g. disease-causing mutations. Additionally, our results pave the way for the design of optimized AQP water channels to be utilized in biotechnological applications.

“…Aquaporin (AQP) membrane, a transmembrane protein with extremely high selectivity and permeability to water molecules, is fabricated by directly or indirectly embedding AQP in the organic matrix membranes (such as those for NF, RO, and FO). The selective permeability of the AQP can achieve a higher water flux and solute interception [124,125].…”

Forward osmosis (FO) is an evolving membrane separation technology for water treatment and reclamation. However, FO water treatment technology is limited by factors such as concentration polarization, membrane fouling, and reverse solute flux. Therefore, it is of a great importance to prepare an efficient high-density porous membrane and to select an appropriate draw solute to reduce concentration polarization, membrane fouling, and reverse solute flux. This review aims to present a thorough evaluation of the advancement of different draw solutes and membranes with their effects on FO performance. NaCl is still widely used in a large number of studies, and several general draw solutes, such as organic-based and inorganic-based, are selected based on their osmotic pressure and water solubility. The selection criteria for reusable solutes, such as heat-recovered gaseous draw, magnetic field-recovered MNPs, and electrically or thermally-responsive hydrogel are primarily based on their industrial efficiency and energy requirements. CA membranes are resistant to chlorine degradation and are hydrophilic, while TFC/TFN exhibit a high inhibition of bio-adhesion and hydrolysis. AQPs are emerging membranes, due to proteins with complete retention capacity. Moreover, the development of the hybrid system combining FO with other energy or water treatment technologies is crucial to the sustainability of FO.

“…Unlike the active layer, the support layer can be formed using various techniques such as electrospinning, non‐solvent induced phase separation, or thermally induced phase separation. [ 17–19 ] Membranes having a PA active layer are thus designated as PA‐TFC membranes. These PA‐TFC membranes have good stability over a wide range of temperatures and pH.…”

“…[ 13 ] Since the active and support layers are prepared using two distinct processes, the properties of each layer can be optimized individually. [ 17,20–22 ] Researchers are increasingly interested nowadays in preparing TFC membranes with integrated sublayers between the substrate and their active layer, using various techniques. [ 23–25 ] This approach has yielded promising improvements in the performance of TFC membranes.…”

This paper is a comparative study on the preparation techniques used to make the support layer of polyamide‐thin‐film composite forward osmosis (TFC‐FO) membranes. The role played by the support layer preparation technique in membrane performance is thoroughly investigated in this study. Electrospinning is shown to produce membranes of lower structural parameter compared to those obtained by conventional phase inversion techniques. The electrospun polyamide selective layer can also be tailored with the required properties. This makes electrospinning a promising process to design efficient FO membrane substrates. It is shown in this work that the FO water flux is more dependent on the internal structure of the support layer than the preparation materials. The main challenge remaining for substrates to operate in FO is to achieve simultaneously a low structural parameter, a high surface porosity, and the required mechanical properties. As most of today's approaches are not suitable, further materials development is essential in future investigations on TFC‐FO membranes.
