Summary: The widespread use of synthetic dyes can lead to the generation of colored wastewaters, which can cause serious environmental problems. This study establishes a novel biohybrid system for the light-driven degradation of dyes, specifically triphenylmethane dyes, using a non-photosynthetic microorganism C. thermocellum self-photosensitized with CdS nanoparticles. The biohybrids exhibit remarkable decolorization effects, and the catalytic activities can be enhanced by controlling the particle sizes of CdS semiconductors.

Summary: In this study, radiochromic films based on a radiation-sensitive dye were investigated for dose monitoring. Chlorine-containing hexachloroethane and a UV-absorber were incorporated to enhance radiation sensitivity and protect the films from light. The films exhibited a significant magenta color upon irradiation, with the intensity increasing linearly with absorbed dose. The films incorporating hexachloroethane showed higher radiation sensitivity compared to those without. The prepared dyed films have potential applications as chemical dosimeters or indicators for radiation processing.

Summary: In this study, a hierarchically porous covalent organic framework foam (TbBd-foam) was fabricated using a simple gas-foaming technique to adsorb and remove two typical TPM dyes from aqueous solution. The foam showed efficient adsorption capacities for removing malachite green (MG) and crystal violet (CV) within 30 minutes, with high maximum adsorption capacities. Additionally, TbBd-foam could be easily recycled by treatment with an ethanol solution containing HCl (0.1%), making it a potential adsorbent for contaminated water remediation.

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: This study investigates the concept of using heat to enhance reverse osmosis (RO) desalination. The effect of temperature on water permeate flux, specific energy, permeate quality, and applied operating pressures is evaluated using an analytical model. The results suggest that under specific conditions, the tradeoff between savings in mechanical pump work and thermal energy input in thermally-enhanced RO can be favorable, leading to overall energy savings.

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.
