Summary: The thermodynamic properties of evaporation of 1-butyl-3-methylimidazolium tetrafluoroborate (BMImBF(4)) ionic liquid were investigated using Knudsen effusion mass spectrometry. The results showed that at non-equilibrium Langmuir conditions, the IL evaporates primarily in the form of neutral ion pairs (NIPs), while under equilibrium conditions, decomposition products dominate the vapor. The main decomposition products were found to be substituted imidazole-2-ylidene and hydrofluoric acid. The vaporization enthalpy and formation enthalpy of NIPs were determined, and it was demonstrated that the system is characterized by partial equilibrium.

Summary: This study utilized the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate as an efficient and environmentally-friendly electrolyte for the electrodeposition of nanocrystalline cobalt films on a silicon substrate. The electrodeposition of cobalt was found to occur by three-dimensional instantaneous nucleation with diffusion-controlled growth, resulting in high-quality and pure metallic cobalt deposits. Elevated current efficiencies were achieved, indicating the great potential of the ionic liquid for cobalt electrodeposition on silicon substrates.

Summary: Two room temperature ionic liquids with the same cation but different anions were studied for their structural, optical properties, and antibacterial activity. Both liquids demonstrated antibacterial activity against gram-positive and gram-negative bacterial strains. UV-vis spectroscopy revealed energy gaps of 3.79 +/- 0.13 and 3.37 +/- 0.04 eV for the two liquids, respectively. The study employed the Sellmeier oscillator model and the Drude-Lorentz model for the first time to investigate the optical and dielectric properties of ionic liquids.

Summary: Ionic liquids are a new class of fluids with excellent tunable properties, and they have been recently explored for heat exchange applications. This review paper focuses on the state-of-the-art 1-Butyl-3-methylimidazolium tetrafluoroborate ionic liquid, discussing its properties, general applications, and its potential as a heat transfer fluid. The addition of solid high conductive nanoparticles greatly enhances the thermal conductivity of the ionic liquid, while the increase in viscosity remains reasonable. These characteristics make it a promising choice for heating and cooling operations, especially at elevated temperatures. The article also presents experimental correlations for density, thermal conductivity, specific heat, and viscosity of the 1-Butyl-3-methylimidazolium tetrafluoroborate ionic liquid. Furthermore, the review examines the variation of thermophysical properties with nanoparticle mass concentration and temperature in nanocolloids based on this ionic liquid. However, further experimental work is necessary to fully understand the real-life applications of ionanocolloids.

Summary: Ionic liquid (IL) pretreatment is a promising approach for pretreating biomass before converting it into sugars, but it is associated with high costs. The combination of [BMIM]BF4: DMSO pretreatment showed the highest delignification and resulted in a highly porous structure. Additionally, this pretreatment reduced the crystallinity of biomass and resulted in the highest cellulose conversion when followed by enzymatic hydrolysis.

Summary: The dielectric properties of nonaqueous microemulsions were studied with IL as the polar phase, revealing a dielectric relaxation and two inflection points in the weight fraction dependence of dielectric parameters. The results indicate static percolation near the critical threshold between IL/O and O/IL subregions, with the relaxation mechanism identified as interfacial polarization. Analysis suggests a closer interaction between IL and TX-100 compared to TX-100 and oil in the microemulsion system.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
