Summary: The overall understanding of cosmic dust particles is mainly inferred from Earth-based measurements and space missions. In order to interpret observations related to dust in different regions of space, computer-modeled dust structures are necessary. This study introduces a tool called REST, which generates realistic rough-surface dust particles based on measured bulk density and porosity.

Summary: This study investigates the influence of particle properties (shape, size, and density) on mixing behavior in a vibrated packed bed mixer for binary and ternary mixtures, using the subdomain mixing index. Two different regimes, percolation and buoyancy control, are identified based on the segregation parameter (Z) value. The Z value combines the effects of various particle properties. The subdomain mixing index is strongly correlated with the segregation parameter. The study finds that in binary mixtures, reducing the density of coarse particles reduces mixing, while reducing the density of fine particles enhances mixing. The segregation behavior of nonspherical particles indicates that shape-induced segregation is not the dominant factor, but nonspherical particles exhibit better mixing than spherical particles.

Summary: The field of light-scattering characterization of single particles has grown rapidly in the past 30 years due to advancements in measurement and simulation capabilities. Various methods have been developed to characterize particles with high geometric resolution, but development has been fragmented and specific to experimental setups. Existing methods are categorized into model-driven, model-free, and data-driven methods, with a focus on algorithms and experimental aspects.

Summary: This study investigated the effect of different substrates on the optical resonances of LiNbO3 nanoparticles and found that the electric and magnetic resonances of the system can be effectively adjusted by changing the substrate. Compared to the impact of dielectric substrate, the interaction between LiNbO3 nanoparticles and the Au film exhibited a sharp resonance peak. The size, shape of the nanoparticles, and the thickness of the SiO2 film between the particle and the Au film significantly influenced the electromagnetic resonance of LiNbO3 nanoparticles.

Summary: In this study, a novel integrated dual-angle DLS prototype was designed to measure particle size by combining microfluidic chip and fiber optic probes. The instrument achieved high accuracy at high concentrations and small sample consumption using a linear regression model for calibration. Additionally, the implementation of dual-angle online measurement in the fiber DLS system with microfluidic chip showed improved repeatability compared to single-angle DLS measurement.

Summary: In this study, a method has been proposed to obtain the velocity and particle size distribution of flowing aerosols through the analysis of light intensity autocorrelation function (ACF) and the application of regularization method. The results from simulations and experiments demonstrate that the proposed method can accurately measure the velocity and particle size distribution of flowing aerosols under different noise levels.

Summary: Using data from the Magnetospheric Multiscale mission, we discovered a double layer within the transition layer of the quasi-perpendicular bow shock. The electric potential generated by this double layer effectively accelerates electrons in the bow shock, as verified by the increase in electron parallel temperature. Additionally, we detected strong whistler emissions near this double layer, suggesting that the accelerated electrons can supply the necessary energy for excitation of the observed whistler waves. Hence, the presence of whistler waves indirectly provides evidence of an electron beam generated by the double layer in the bow shock.

Summary: The synthesis of iron(III) oxide particulates from iron pentacarbonyl (IPC) in a flame spray pyrolysis process is predicted using a multiple mapping conditioning (MMC) method. MMC is coupled with carrier-phase large eddy simulations and a sectional description of the population balance equation. The results show that parameter variations within sensible boundaries can significantly improve agreement with measurements and have large effects on the predicted particulate size distribution.

Summary: By developing the GFIT3 algorithm to account for aerosol scattering effects, the performance of remote sensing of GHGs in polluted urban atmospheres has been improved. Evaluation using synthetic spectra showed errors in CO2 and CH4 retrievals were less than 1% on average, indicating that atmospheric scattering does not induce large biases in retrievals when aerosols are properly characterized. Comparing GHG retrievals from GFIT3 with those from the CLARS-GFIT algorithm revealed a significant correlation between retrieval bias and aerosol optical depth (AOD).
