Summary: Individual atmospheric particles can contain mixtures of primary organic aerosol (POA), secondary organic aerosol (SOA), and secondary inorganic aerosol (SIA), with the potential to have three distinct liquid phases. The presence of these phases is influenced by the elemental oxygen-to-carbon (O:C) ratio of the SOA, impacting equilibration timescales and potential effects on cloud formation and atmospheric chemistry.

Summary: Packed column SFC is popular for separations due to low CO2 cost and environmental benefits. New functionalized cyclofructan columns show improved selectivity and efficiency in achiral SFC separations. Adding small amounts of water to the methanol modifier in CO2 improves peak symmetries for amines. These new stationary phases offer greener approaches to separation problems.

Summary: The combination of a hydrophobic ionic liquid catalyst and a fatty alcohol synergistically improves the cycloaddition reaction of CO2 to epoxides, producing cyclic carbonates. This approach not only allows for catalyst recovery and product purification, but also enhances CO2 conversion in the reactor, opening up the possibility of process intensification through integrated CO2 capture and conversion.

Summary: The simultaneous stabilization of water droplets in a highly non-polar oil phase using temperature responsive, soft and hydrophilic PNIPAM microgel particles and solid and hydrophobic silica nanospheres allows for the formation of stable water-in-oil emulsions with a larger internal interface. This synergistic effect enables the particles to protect the droplets from coalescence and accelerate the emulsions sedimentation speed, while still maintaining the ability to redisperse the droplets by gentle shaking. The study provides a model to explain the phenomena observed in terms of droplet size measurements and cryo-SEM studies.

Summary: In this study, the electrostatic complexation between two strong polyelectrolytes, PDADMAC and P(St-co-SSNa), was investigated. The results showed that all the anionic charges of P(St-co-SSNa) were available for complexation with PDADMAC or a cationic dye. The strength of the electrostatic interaction was found to overcome the hydrophobic effect responsible for pearl formation, and the efficiency of complexation was not significantly influenced by differences in charge density between PDADMAC and P(St-co-SSNa). Additionally, the formation of colloidal PECs was observed to occur in two distinct steps: the pairing of opposite charges to form small primary complex particles, followed by their aggregation within finite-size clusters.

Summary: Adding nanoparticles into drilling fluids can reduce fluid invasion, but the suitable nanoparticles should be chosen to avoid safety issues caused by hydrate formation in wells. The study found that hydrophobic nano-CaCO3 particles promote hydrate formation, while hydrophilic ones can inhibit hydrate formation at certain particle sizes and concentrations. Among them, hydrophilic nano-CaCO3 with a particle size of 20 nm and addition of 3.0 wt% showed the strongest inhibition effect in preventing hydrate formation under the given experimental conditions.

Summary: This study examines the dynamics of dust mitigation from inclined hydrophilic/hydrophobic glass surfaces after introducing electrostatic repulsion. The findings suggest that hydrophobizing the surfaces reduces particle adhesion and the force of adhesion remains larger for smaller particles. Surface tilting influences the dynamics of inflight particles, dust mitigation rate, and optical characteristics of the surfaces.

Summary: A controlled study was conducted to investigate the effects of different types of collectors on the flotation ability of niobium oxide minerals with various particle sizes. The study found that hydroxamate-based collectors outperformed carboxylate-based collectors in floating both coarse and fine pyrochlore, indicating the importance of a strong affinity hydrophilic group for effective fine particle flotation. Furthermore, the study revealed that the longer hydrocarbon chain of the collector benefited the flotation recovery of relatively coarse particles.

Summary: Optical trapping is commonly limited to spherical nonabsorbing droplets, but electrodynamic traps provide new opportunities for trapping and studying particles regardless of their absorption strength and morphology. By combining an electrodynamic linear quadrupole trap with a cavity ring-down spectrometer, researchers were able to trap single droplets and measure their optical properties over time, expanding beyond spherical shapes. The results have implications for accurate remote sensing and radiative forcing calculations, as well as potential applications in atmospheric science for precise light scattering measurements.

Summary: This paper introduces a refined numerical model for the evaporation and transport of droplets of binary solutions. The model is validated against other models in the literature and experimental measurements of trapped and freefalling droplets. It accurately represents the behavior of solution droplets in different regimes, accounting for hygroscopic behavior and the Kelvin effect. Simulations of pure water evaporation and sodium chloride droplets are validated experimentally, and the simulations accurately represent the experimental data. The model is also used to analyze the morphologies of dried sodium chloride particles at different drying rates.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
