“…This decreases the cross-membrane vapor pressure difference, hence the membrane flux. However, it has been demonstrated [ 16 , 17 , 18 ] that heating the feed water at the feed–membrane interface instead of heating the bulk feed stream outside the membrane module can reverse the temperature polarization with an enhancement of the evaporation process. Thus, the heating of the membrane surface can be obtained by the addition of photothermal materials such as plasmonic [ 16 , 17 , 19 ] or carbonic materials [ 18 , 20 ] to the MD system.…”

Developing photothermal solar driven membrane distillation (PSDMD) is of great importance in providing fresh water for remote off-grid regions. The production of freshwater through the PSDMD is driven by the temperature difference between feed and distillate sides created via the addition of efficient photothermal nanostructures. Here we proposed nickel sulfides and nickel tellurium nanoparticles (NPs) to be loaded into the polymeric membrane to enhance its performance. Ag and CuSe NPs are also considered for comparison as they are previously used for membrane distillation (MD). Our theoretical approach showed that all of the considered NPs increased the temperature of the PVDF membrane by around a few degrees. NiS and NiTe2 NPs are the most efficient solar light-to-heat converters compared to NiTe and NiS2 NPs due to their efficient absorption over the visible range. PVDF membrane loaded with 25% of NiCs NPs and a porosity of 32% produced a transmembrane vapor flux between 22 and 27 L/m2h under a 10-times-amplified sun intensity. Under the same conditions, the PVDF membrane loaded with CuSe and Ag NPs produced 15 and 18 L/m2h of vapor flux, respectively. The implantation of NPs through the membrane not only increased its surface temperature but also possessed a high porosity which provided a higher distillation and energy efficiency that reached 58% with NiS NPs. Finally, great agreement between our theoretical model and experimental measurement is obtained.

“…25,26 To date, the application of valleytronics has been extended to various fields, including optoelectronics, [27][28][29][30][31][32][33][34] thermoelectricity [35][36][37] and thermoplasmonics. 38 Actually, valleytronics is boosted by the discovery of 2D hexagonal crystals, 39,40 such as graphene and monolayer transition-metal dichalcogenides (TMDCs), which have been proposed to possess the valley-contrasting physics. However, for graphene, the generation of valley current requires additional schemes due to the presence of inversion ðPÞ symmetry, [41][42][43] which makes it less desirable for valleytronic applications.…”

“…Membrane distillation (MD) is an emerging thermal desalination technology using a microporous hydrophobic membrane to harvest water vapor from hot saline feed solutions. , Compared with the state-of-the-art desalination technology (i.e., reverse osmosis and mechanical vapor compression), MD is able to deal with hypersaline wastewaters using low-grade energy (e.g., industrial waste heat and solar energy), thereby attracting heightened research interests in industrial wastewater reclamation. − However, to date, MD has not been widely used in practice because conventional MD membranes face several challenges when being used for treating complex saline wastewater. , …”

As an emerging desalination technology for hypersaline wastewater treatment, membrane distillation (MD) faces a critical challenge of membrane wetting. The state-of-the-art wetting mitigation strategy in MD is to use novel membranes that are commercially unavailable and difficult to fabricate. This study proposes an operational mode, negative pressure MD (NPMD), as a novel wetting mitigation strategy in MD operations. Compared with conventional MD, NPMD can substantially enhance the wetting resistance of commercially available hydrophobic MD membranes. Specifically, in a conventional direct contact MD (DCMD) operation, a polyvinylidene fluoride (PVDF) membrane is easily wetted by a 0.1 mM sodium dodecyl sulfate (SDS) feed solution, while in NPMD, the PVDF membrane can remain unwetted with a 0.2 mM feed solution. By determining the liquid entry pressure (LEP) of the PVDF membrane using an impedance-based technique, the working mechanism of NPMD for wetting mitigation is illustrated, and such a mechanism is further confirmed by DCMD experiments using feed solutions containing ethanol. With a negative gauge pressure on the feed stream, the transmembrane hydraulic pressure becomes lower than the LEP of the PVDF membrane, thereby mitigating membrane wetting. As a simple yet effective wetting mitigation strategy, NPMD can be readily implemented in practice with commercially available hydrophobic membranes, showing vast potential to advance MD applications.
