Summary: Posidonia oceanica in Mediterranean develops a complex belowground structure capable of storing large amounts of carbon over thousands of years. Mapping techniques and sediment sampling were used to assess the size and variability of carbon stocks. This study quantifies the organic and inorganic carbon stocks in the P. oceanica matte of Calvi Bay using sub-bottom profiler imagery and sediment core analysis. The data revealed the heterogeneity of blue carbon stocks in seagrass meadows and discussed the variability of carbon storage capacity influenced by substrate.

Summary: This study explored the potential of using Posidonia oceanica egagropili, a marine waste, as a renewable source to enhance extracellular melanin production in Streptomyces roseochromogenes ATCC 13400. It was found that adding egagropili powder to the culture medium significantly increased melanin biosynthesis, and further investigation revealed that this enhancement was due to the synergistic effect of lignin carbohydrate complex and holocellulose components in egagropili.

Summary: The study investigated the concentrations of eight trace elements in Posidonia oceanica leaf blades and sediments sampled from 23 stations along the Turkish-Mediterranean Sea coast, revealing significant distribution differences among sampling stations. While most of the trace element concentrations varied significantly among stations without a consistent trend, Zn, Cd, Cu, and Pb in the sediment were determined as non-polluted based on sediment quality guidelines, with some stations showing moderate to heavy pollution for Cr, Ni, and As. The findings suggest that the western sites of the study area are heavily exposed to trace elements due to human activities, with significant positive correlations detected between anthropogenic and natural sourced trace elements.

Summary: This paper presents a method for quantifying the benefits of beaches in reducing storm and long-term coastal flood risk. The method is important for cost-effective decision-making on climate change adaptation in coastal areas. It considers the dynamic interaction of storm erosion, long-term shoreline evolution, and flooding to quantify the flood protection benefits of beaches. The results show that considering erosion is crucial for accurate flood damage estimation and that maintaining present-day beach width can significantly reduce flood damage.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.

Summary: In this study, a novel polydopamine-functionalized lignin-containing pulp foam evaporator with high-efficiency desalination and multi-contaminant adsorption capabilities was designed. The foam evaporator showed excellent light absorption, water absorption, thermal conductivity, and chelation abilities, allowing for solar evaporation and contaminant adsorption synergistically. It also exhibited potential applications in metal ion concentration and contaminated seawater treatments, and demonstrated superior biodegradability compared to poly-styrene foam. This foam material holds promise for developing multifunctional photo-thermal systems for solar-driven water purification.
