Summary: The aim of this study is to reduce the tortuosity of proton conductive pathways within polymer electrolyte membranes for anhydrous PEM fuel cells. By incorporating microsize chopped fibers, modified nanosilica, and a deep eutectic solvent into the Nafion matrix, the proton conductive pathways are extended and the conductivity is greatly improved. The measurements show that the Nafion/DES composite membrane with 5 wt% short fibers and 2 wt% nanosilica exhibits super proton conductivity and promising fuel cell performance.

Summary: In this study, a novel and simple water-salt-in-deep eutectic solvent (WS-DES) strategy was developed to enhance the ionic conductivity, reduce the viscosity, and lower the freezing temperature of deep eutectic solvent (DES). The WS-DES electrolyte showed significantly improved performance compared to the initial DES in supercapacitor devices, with higher specific capacitance, better rate performance, lower IR voltage drop, and lower internal resistance. Furthermore, the WS-DES electrolyte demonstrated excellent electrochemical stability even at extreme conditions of -40 degrees C.

Summary: For the first time, conductive starch/poly(ionic liquid) hydrogels were prepared from a polymerizable deep eutectic solvent using frontal polymerization. The study showed that the presence of starch in the hydrogels significantly improved their mechanical strength and electrical conductivity, attributed to a strong interfacial interaction between starch and the polymer hydrogel network. Water absorption was found to enhance the conductivity of the composite hydrogels.

Summary: Deep eutectic solvents (DESs), a new type of green solvent, are considered as replacements for ionic liquids in various applications. Therefore, studying the thermophysical properties of DESs is crucial for their applications. In this research, DESs containing triethylene glycol and choline chloride (ChCl) were synthesized in different molar ratios, and their thermal conductivity, viscosity, and density were systematically investigated. The addition of ChCl decreases the thermal conductivity but increases the viscosity and density of DESs, and the dependence of these properties on the molar fraction is analyzed.

Summary: This paper introduces the advantages of nanocellulose derived from lignocellulose materials, such as high strength, lightweight, biodegradability, and renewability. Due to the complex and dense cell wall structure and poor solubility in water and most solvents, lignocellulose materials are difficult to dissolve directly and utilize effectively in practical production. The pretreatment technology is discussed, which exposes the amorphous areas, eliminates unnecessary non-cellulose components, and facilitates the subsequent applications. Traditional and green solvents used in the pretreatment of lignocellulose materials, as well as their mechanisms, advantages, and disadvantages, are introduced. Furthermore, the mechanism, process, advantages, and potential applications of deep eutectic solvent as a pretreatment solvent are discussed, along with suggestions for the future use of green solvents in treating lignocellulose materials.

Summary: In this study, deep eutectic solvents (DESs) were prepared using ammonium iodides and iodine. Various mixtures of ammonium iodides with iodine were examined, and specific DESs with high electrical conductivities were formed. The viscosity of the DESs decreased with increasing iodine concentration. Raman spectra analysis indicated that the high electrical conductivity of the DESs was attributed to the Grotthuss mechanism.

Summary: In this study, switchable ionic liquids were synthesized and screened to improve the polarity and recyclability of deep eutectic solvents. By coupling with hydrogen-bond donors, a switchable-DES system with modified properties, such as viscosity, conductivity, and pH, was formed, leading to enhanced solubility of lignin compounds and improved molecular weight and uniformity. This proposed system has potential applications in the fractionation of lignin compounds and downstream industrial processes.

Summary: In this study, we demonstrated the easy preparation of deep eutectic solvents (DESs) using various imidazolium iodides and iodine. The electrical conductivity of the DESs could be controlled by changing the mixture composition and imidazolium cation species. Especially, the DES composed of 1-ethyl-3-methylimidazolium iodide and iodine in a 1:4 molar ratio exhibited a high electrical conductivity of 70 mS cm-1, which was higher than that of the ionic liquid mixtures with iodine. The high electrical conductivity of DESs can be attributed to the Grotthuss mechanism in polyiodide based on viscosity results, Raman spectrum measurements, and quantum chemistry calculations.

Summary: With the development of electronic machinery, the traditional heat exchange working fluid is inadequate in extreme working environments. Deep eutectic solvent, as a new type of fluid, demonstrates promising thermal stability, low cost, and non-toxicity through hydrogen bond association, making it an efficient heat transfer working fluid. This study utilized glycerol/sodium acetate trihydrate deep eutectic solvent as a base solution, prepared nanofluids filled with TiO2, Al2O3, and Fe2O3 nanoparticles, and discussed the mechanism of thermal conductivity change at the atomic and microscopic levels. Experimental results showed that the prepared deep eutectic solvent system reduced viscosity by 58.03% and increased thermal conductivity by 17.2% compared to glycerol at 25 degrees Celsius. Furthermore, the impact of nanoparticles on thermal conductivity and specific heat capacity was investigated, with thermal conductivity being improved by the addition of Fe2O3 nanoparticles and the specific heat capacity of nanofluids more than doubling after nanoparticle incorporation.

Summary: In this study, the anionic homopolymerization, random and block copolymerizations of several vinyl monomers were explored in deep eutectic solvent (DES). The microstructures and molecular weights of the polymers were characterized, and their thermal properties were investigated. The results showed that DES can be used to prepare polymerization products with desired characteristics, and it can be recycled for multiple reactions without affecting the final product. The use of DES as a reaction medium for anionic polymerization offers milder reaction conditions and expands the application of active organolithium reagents.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
