Summary: The study explores the use of thermal energy from solar radiation and industrial waste heat to enhance the performance of membrane processes. It is found that using heat to improve pressure retarded osmosis can lead to significant improvements in water flux and power density. The temperature of the feed solution is found to be more important than the draw temperature. The results show that a hot feed solution can produce a warmer membrane, which increases permeability and reduces polarization, mainly due to the well-mixed nature of the feed boundary in pressure retarded osmosis.

Summary: The study found that the channel pressure drop induced by the spacer became the most influential cost bottleneck on COW for waste heat operated MD processes, with pumping costs having a greater contribution to total operating costs in DCMD compared to AGMD. The use of TPMS spacers can reduce the COW of waste heat operated DCMD by decreasing the thermal energy component, as flux improvement achieved by TPMS spacers reduces the operating cost.

Summary: Membranes offer a scalable and cost-effective approach to ion separations for lithium recovery. The impact of pH and feed salinity on nanofiltration's selectivity in salt-lake brines is uncertain. By analyzing experimental and computational data, we found that acid-pretreated feed solutions can enhance the Li+/Mg2+ selectivity of polyamide membranes by 13 times. The appropriate Cl-/SO42- molar ratios in feed solutions can improve predictions of ion rejection and Li+/Mg2+ separation factors by up to 80%.

Summary: This study measured the solution vapor pressure of ternary acetonitrile (MeCN) H2O-NaCl-MeCN mixtures and used a mass action solution model to characterize solute speciation. The results showed that accounting for speciation significantly reduced the variability of the vapor-liquid and solid-liquid equilibria. Additionally, the precipitation of NaCl in the mixtures was found to be independent of the dielectric constant but related to the solution activity. Comparison with other ternary mixtures revealed that salt-induced liquid-liquid equilibrium exists in solutions with positive deviations from Raoult's law and organic-rich mixing free energy profiles. This study is the first to apply a speciation-based solution model to a ternary system and contributes to a better understanding of multi-component solution equilibria.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
