Summary: Gel polymer electrolytes (GPEs) are used as alternatives to liquid electrolytes in lithium-metal batteries (LMBs). Adding diluent 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropyl ether (TTE) to regulate the electrolyte structure improves the electrochemical stability and ion transport properties of GPEs. The addition of TTE enhances ion association and forms a robust and low-impedance solid electrolyte interface (SEI) on the anode surface. This study provides an effective approach for controlling solvation structures in GPEs, which can advance the design of GPE-based LMBs in the future.

Summary: The ability to protect materials from fire is crucial in various industries and life safety systems. This study demonstrates that the fire resistance of atomically thin materials can be significantly enhanced by changing their microstructure. Cellular graphene aerogels show exceptional fire-retardant and self-extinguishing properties due to their prevention of carbonyl defect formation and capture of nonflammable carbon dioxide gas in the pores.

Summary: The study combined DFT and KMC techniques to investigate vacancy evolution at the interface between lithium and different SEI materials, revealing that lithiophilic interfaces facilitate surface smoothness by quickly filling vacancies while lithiophobic interfaces lead to rough surfaces. The predicted critical stripping current density is faster at lithiophilic interfaces, indicating that nanoscale interface and coating design can effectively maintain a smooth lithium surface.

Summary: In this study, a liquid-phase input end is added to the cup burner to test the fire-extinguishing effect of C6F12O on lithium-ion battery syngas. The minimum extinguishing concentration (MEC) of C6F12O is determined, and the physical and chemical effects of C6F12O on lithium-ion battery syngas fire are quantified using the perfect stirred reactor (PSR) model. The results indicate that the fire-extinguishing effect of C6F12O on lithium-ion battery fire is mainly due to its physical cooling effect.

Summary: This study reports a novel separator design that can absorb thermal energy within the battery and improve fire safety. The separator is made of a thermo-responsive composite material, featuring a phase-change material (PCM) and a flame retardant. The PCM can store heat and control the release of the flame retardant. Upon thermal runaway, the PCM undergoes solid-liquid transition to release the flame retardant, effectively reducing the safety risks.

Summary: In this study, a gel polymer electrolyte (GPE) is presented to enhance the nonflammability of lithium-ion batteries (LIBs). The GPE blocks radical-initiated chain reactions that can lead to thermal runaway and fire incidents. The GPE polymer is soluble in carbonate electrolytes and can be cross-linked in the presence of a commonly used lithium salt. It gelates at a low concentration in the electrolytes and has functional side chains that scavenge radicals. LIB cells with the GPE show excellent thermal and mechanical stability without compromising cell performance. The GPE exhibits high transference number of lithium ions and ionic conductivity, resulting in improved cell performance under normal operation conditions.

Summary: This study investigates the influence of the flexible spacer parity of a guest photoactive liquid crystalline dimer on the photonic bandgap features of the cholesteric and twist grain boundary smectic C phases of the host molecule. The results show that the parity of the photoactive dimer affects the width of the photonic bandgap and the blue-shift of the cholesteric phase. Additionally, the parity of the dimer also affects the layer spacing and two-dimensional periodicity of the liquid crystalline phases.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study investigates the effects of different transition metal decorations on B12N12 nanocages on the adsorption properties of nitrosourea drugs using computational methods. The results reveal the presence of weak non-covalent interactions between metals and nanocages, and the interaction between drugs and nanocages plays a significant role in drug adsorption. Compared to free drugs, the adsorption of drugs on nanocages can facilitate electron transfer, reduce energy gaps and chemical hardness, indicating activity at the target site.

Summary: In this study, the selective oxidation of aromatic aldehydes was investigated using Ru(VI) as a catalyst and hexacyanoferrate (III) as a cooxidant in an alkaline medium. The reaction mechanism involves complex reaction orders for the oxidant and the aromatic aldehyde, while the reaction order for Ru(VI) is one. The proposed mechanism includes two catalytic cycles and the formation and decomposition of complexes. Quantitative structure-activity relationship analysis showed that deactivating groups in the para-position enhance the process.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

Summary: This study examines the sensitivity of the thermal conductivity of water-based alumina nanofluids to changes in concentration, sphericity, and temperature. The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.

Summary: This paper reports on the synthesis, structural characterization, spectral and nonlinear-optical properties of glass nanocomposites made of glass forming ionic liquid crystals and nanoparticles. The study reveals that by exciting the nanocomposites within their absorption band, a control over effective optical nonlinearities can be achieved, allowing the modification of the magnitude and sign of the effective nonlinear absorption coefficient. The proposed strategy using metal-alkanoates based glass-forming ionic liquid crystals and nanoparticles shows great potential for the development of nanophotonics and plasmonics technologies.
