Summary: In this study, a stable ionic liquid was used to dissolve aluminum in aluminum chloride solution, and the resulting mixture was used as a low-temperature electrolyte for the electrolytic recovery of pure aluminum. Experimental results showed that aluminum could be electrodeposited from the electrolyte, and impurity elements of the aluminum alloy could also be removed by the electrolytic method. Scanning electron microscopy observations revealed that smooth and adherent deposits were obtained at a specific voltage and temperature range, with high aluminum purity. This study may contribute to the application of ionic liquids in the low-temperature recycling of waste aluminum alloys.

Summary: In this study, a separation and purification process of U(VI), Zr(IV) and I-2 from various fission products in nitric acid solution was investigated using 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([C(4)mim][NTf2]) and dibutyl-3-(3-methylimidazolium)propylphosphoramide bis(trifluoromethanesulfonyl)imide-task specific ionic liquid (phosphoramide-TSIL). The phosphoramide-TSIL exhibited reduced ligand loss compared to dibutyl propylphosphoramidate, and successful stripping of U(VI), Zr(IV) and I-2 was achieved using different solutions. The phosphoramide-TSIL/[C(4)mim][NTf2] showed good irradiation stability and recyclability, and has potential for application in separation and purification in actual radioactive environments.

Summary: In this study, the densities and viscosities of binary mixtures of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide, [bmim][NTf2], and ethylene glycol (EG) were experimentally measured. A first-order polynomial and Vogel-FulcherTammann equation were used to estimate the densities and viscosities of the mixtures, respectively. The excess molar volume, viscosity, and Gibbs energy of activation for viscous flow were calculated and fitted to the Redlich-Kister equation. The thermal expansion coefficients and partial and apparent molar volumes of [bmim][NTf2] and EG in their binary mixtures were also investigated.

Summary: The interface between ionic liquids (ILs) and metals, particularly in electrochemical deposition and nanoscale tribology applications, was studied. The interaction between [Py-1,Py-4]TFSI and [EMIm]TFSI ILs and platinum was found to be minimal, while strong interaction with the surface was observed in the case of [EMIm]TFSI. On the other hand, massive decomposition of both ILs occurred on the aluminum surface. The spectra revealed cleavage of C-F or N-S bonds in the [TFSI](-) anion and the appearance of various decomposition products at the interface.

Summary: This study compared experimental photovoltaic performance and numerical simulations of perovskite solar cells with MoS2 hybrid hole transporting layer (HTL) structure, finding that MoS2 effectively acted as a barrier to ion migration and minimized shunt contact. By modeling the electrical characteristics of the cells, optimal absorber and MoS2 thicknesses were determined, with MoS2 successfully concealing visible pinholes on the perovskite layer's surface. The study suggests that structural and morphologic tuning can guide optimization and fabrication of devices based on simulation and experimental perspectives.

Summary: This study investigated the synthesis and properties of bio-based polyurethane (PU) films using palm kernel oil-based polyols (PKO-p). The results showed that the NCO/OH ratio had an impact on the infrared spectroscopic, molecular weight distribution, thermal behavior, and impedance spectroscopic properties of the PU films. Higher content of PKO-p resulted in lower crosslinking and poor physical properties. This study demonstrated the promising physicochemical properties of PKO-p-based PU films for polymer electrolyte application.

Summary: Organic dye sets a benchmark for dye-sensitized solar cells (DSSCs) application. Replacing organic dyes with inorganic phases poses a significant challenge. Surface modification techniques are considered key to improving DSSC efficiency. This study investigates the use of transition metal sulfides (TMS), specifically kesterite (Cu2ZnSnS4, CZTS), as an inorganic absorber layer for DSSCs. Results show that a lower molar ratio of CZTS compared to the N719 dye produces a stable DSSC with improved power conversion efficiency and incident photon-to-current efficiency. Higher concentrations of CZTS lead to instability and reduced performance.

Summary: Cu-doped ZnO was prepared using the sol-gel method, and various techniques were used to investigate the effect of copper impurities on the physical characteristics of p-type ZnO. The results showed that the increase of Cu content led to changes in the orientation and morphology of the films. The highest transmittance was observed at 9 wt% Cu. All doped samples were found to be p-type semiconductors. The presence of a high amount of oxygen vacancies resulted in reduced magnetism.
