Summary: This study investigates the physicochemical properties of a series of cation-fluorinated ionic liquids and provides experimental evidence for nanosegregation and triphilicity in these liquids. The introduction of fluoroalkyl chains enhances hydrogen bond interactions between anions and cations and leads to structural rearrangements. The study also demonstrates the use of a group contribution method to predict the density of the liquids.

Summary: Hybrid materials based on ionic liquids (ILs) and polymers are widely used for the development of smart and multifunctional materials. However, the structural organization of ILs within the polymer matrix is not well understood. This study investigates the structural organization of different ILs incorporated into polyvinylidene fluoride (PVDF) films and analyzes their effects on the morphological and physical-chemical properties of the materials.

Summary: Developing greener hydrometallurgical processes by substituting conventional solvents with silica-based porous liquids for metal liquid-liquid extraction is proposed in this study. The properties of the liquid can be adjusted by varying the number of ethylene oxide units in the canopy formed by modifying sulfonated hollow silica particles with polyethoxylated fatty amines. The viscosity of the liquid is influenced by the density and size of the silica spheres. Hydrophobic porous liquids are successfully synthesized and are proven to be necessary for metal extraction in preliminary tests.

Summary: Proteins can be stabilized and have improved properties in the presence of ionic liquids (ILs) as cosolvents or surfactants. By using techniques such as small-angle X-ray scattering (SAXS), fluorescence microscopy, and coarse-grained molecular dynamics (CG-MD) simulations, the interaction between ILs and proteins like lysozyme and bovine serum albumin has been studied. The results show that ILs help maintain the globular structures of proteins and can be used for formulating protein-based pharmaceuticals.

Summary: A series of highly-fluorinated triaminocyclopropenium salts were prepared and their properties as ionic liquids were investigated. Different cations were obtained by reacting pentachlorocyclopropane or tetrachlorocyclopropene with bis(2,2,2-trifluoroethyl)amine and a trialkylamine. The salts were characterized by thermal measurements, solubility properties, density, viscosity, and conductivity, and X-ray diffraction studies showed the formation of fluorous and hydrophilic regions.

Summary: The synthesis and thermotropic behavior of certain di-alkyloxy-phenyl-1,2,4-triazolium trifluoromethanesulfonate salts with a seven-carbon atom perfluoroalkyl chain on the cation were investigated. The fluorinated salts exhibited typical liquid crystalline behavior, with a 1,2,4-triazole core and varying lengths of alkyl chains on the phenyl ring. The mesomorphic properties of these salts were studied using differential scanning calorimetry and polarized optical microscopy. The results showed the presence of a monotropic, columnar, liquid crystalline phase in the tested salts, with an increased temperature mesophase range and the presence of two enantiotropic mesophases observed with the increase in alkyl chain length on the phenyl ring.

Summary: In this study, hydrophobic ionic liquids (ILs) were used for the dissolution and selective extraction of polyhydroxy compounds. The interaction between ILs and polyhydroxy compounds was analyzed, and it was found that these ILs showed strong selective extraction ability. The regenerated ILs maintained their structure after polyhydroxy compounds were extracted by water. This research provides a promising direction for the development of a green and efficient method for fractionating polyhydroxy compounds based on hydrophobic ILs.

Summary: This study discusses the synthesis and characterization of a new class of 1,2,4-oxadiazolylpyridinium as a cationic scaffold for fluorinated ionic liquid crystals. A series of 12 fluorinated heterocyclic salts based on a 1,2,4-oxadiazole moiety, connected to an N-alkylpyridinium unit and a perfluoroheptyl chain, with different alkyl chain lengths and counterions, have been synthesized. The thermotropic properties of these salts, particularly the existence of an enantiotropic mesomorphic smectic liquid crystalline phase for six bis(trifluoromethane)sulfonimide salts, have been investigated.

Summary: The study investigated the effects of alkyl substitutions at alpha or beta position adjacent to amino group of primary alkanolamine ligands on CO2 absorption and physicochemical properties of metal chelated dual functional ionic liquids. The results showed that introduction of alkyl group can enhance CO2 capacity and the effect at alpha position is more significant. DFT calculations revealed that alkyl substitutions reduce the Mulliken charge of N and O atom, weakening the cation coordination interaction and decreasing the density and speed of sound of DFILs.

Summary: This research focuses on designing a bio-based epoxy-silica hybrid material enriched with SiO2 nanoparticles for stone conservation. Isosorbide, a sugar derivative from renewable sources, was used to develop epoxy thermosets functionalized with silica to form hybrid organic-inorganic networks. Various characterization techniques were used to study the properties of the materials. The resulting epoxy-silica nanocomposite showed excellent thermo-mechanical and hydrophobic properties, making it a potential candidate for stone conservation.

Capacitive deionization (CDI) emerges as one of the most sustainable desalting techniques due to its environmental friendliness and efficiency. This study focuses on the preparation and evaluation of high-entropy oxides (HEOs) and carbon/HEO composites as potential CDI electrode materials. The results show that the specific capacitance increases when the carbon matrix and smaller-sized HEO nanoparticles are synergistically coupled.

Summary: In this paper, passivated ultrathin Cu (In1-xGax)Se2 solar cells with different bandgap grading configurations were physically modeled. The impact of absorber doping density, electron affinity, and operating temperature on device performance was observed. ZnS was used as a buffer layer to replace CdS and improve cell efficiency. Simulation results showed that a high bandgap at the front and rear sides with an acceptor density of 2 x 10^(16) provided the best electrical cell parameters: J(sc) of 31.53 mA/cm^2, V-oc of 742.78 mV, FF of 77.50%, eta of 18.15%. These findings can guide the optimization of new single and/or tandem cells for high efficiency.

Summary: In this study, ultrathin Cu (In1-xGax) Se-2 solar cells were investigated using numerical simulations. The impact of different loss mechanisms, such as interface trap density (D-it) and absorber trap density (N-t), on cell performances were explored. Research found that recombination through traps is the primary loss process in the investigated cells. Additional simulations showed significant performance gains for different cell pitch sizes, absorber doping densities, Ga content, and graded bandgap under AM1.5 illumination. The proposed u-CIGS/PERT silicon device offers insights into the optimization of ultrathin-film CIGS solar cells.

Summary: Discovering low-cost and earth-abundant electrocatalysts for oxygen reduction reaction (ORR) is crucial for advanced energy conversion technologies. A series of carbon-based ORR electrocatalysts were prepared using a two-step pyrolysis method at 600 and 900 degrees C. Different carbon, nitrogen, and sulphur sources were utilized, along with iron and copper salts, to produce non-noble metal-doped carbons. The materials were characterized extensively, and the best ORR performance was observed in sulphur- and nitrogen-modified carbons with nanotubes, indicating the occurrence of synergistic effects between heteroatoms and nanotubes.
