“…14,15 Undoubtedly, the deliberate design and development of adsorbent materials are of central importance to guarantee the stable harvesting of marine uranium while accelerating the commercialization of UES. 12 The origin of UES dates back to the ''Project Oyster'' initiated by the United Kingdom in the early 1950s. Since the first public report by Davies et al in 1964, 16 UES has spurred considerable interest among research entities worldwide.…”

“…Uranium is a valuable fuel resource for nuclear power generation. Seawater is the most important uranium source as it accommodates a huge amount of uranium (approximately 4.5 billion tons), which is 1000-fold greater than that contained in the earthy ores. − However, due to the relatively low uranium ion concentration of seawater (approximately 3 μg/L), high nonuranium cation contents, and high seawater salinity, the conventional techniques for uranium extraction from seawater, for instance, the adsorption methods, severely suffer from several drawbacks, including unpleasant uranium selectivity and low uranium extraction capacity. , Thus, there is a need to develop an efficient and well-performing technology for sustainable uranium recovery from seawater.…”

Metal–phenolic networks (MPNs) are novel supramolecular materials with numerous applications in the field of advanced material science and engineering due to their plentiful fascinating features. Following the first assembling of MPN films on diverse solid surfaces in 2013, MPN materials have attracted much attention in the membrane technology field to improve membrane multifunctionality through membrane surface or matrix modification for membrane structural stability, durability, and filtration efficiency enhancements. Moreover, the incorporation of inorganic nanomaterials, such as nanoparticles, nanotubes, nanorods, and nanosheets, and hydrophilic polymers, for instance, zwitterions and polyvinylpyrrolidone (PVP), can enable further improvements of MPN-based membranes for diverse water filtration applications. This review has critically summarized the recent MPN-based membrane modifications and identified areas that need to be considered in further research to enhance membrane durability, filtration performance, and operational lifetime. Overall, it is foreseen that the novel membranes, as well as an ever-widening scope of membrane applications based on the MPN material, will constantly emerge.

To extend the temperature-controlled biohydrogel system from peptides to proteins, we synthesized a protein hydrogel by integrating super uranyl binding protein (SUP) and N-isopropylacrylamide (NIPAM). The protein hydrogel adsorbs trace uranyl from seawater and releases it only by separate temperature regulation. We explored the mechanism of the hybrid hydrogel to regulate SUP activity by comparing different immobilized sites and analyzing viscoelastic effectiveness. Stretching amino acid residues near the uranyl binding site plays a key role in regulation, and the volume variation of the hybrid hydrogel across the low critical solution temperature provides sufficient driving force to deform the SUP. This work demonstrates the prospective potential of using other proteins in hydrogel systems for functional regulation.
