Summary: A bended ribbon biomass particle model was developed to investigate the transport properties inside a riser reactor. The residence time distribution (RTD) of particles was analyzed using the Eulerian-Lagrange method. The study examined the effects of sampling height, particle density, particle size, and gas-to-solid mass ratio on the RTD. The results showed that ribbon biomass particles exhibited a typical annular-core spatial distribution during transportation. The RTD of particles followed an approximate single-peaked normal distribution, with the mean residence time reaching up to 0.7 s for particles with a density of 1200 kg/m3. The flow patterns approached plug flow when the particle length exceeded 12 mm. The study also highlighted the significant impact of the gas-to-material mass ratio on the particle flow pattern.

Summary: The nucleation and growth kinetics of benzoic acid were studied in a population balance model. The experimental information obtained using process analytical technologies was used for parameter estimation. A developed model incorporating supersaturation and solvent composition as factors accurately predicted the crystallization process. This work provides a foundation for further simulation, optimization, and control studies of benzoic acid in antisolvent crystallization.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.

Summary: A clip-like hybrid nanogenerator (HNG) device incorporating lead-free silver niobate (ANb) microparticles embedded in polydimethylsiloxane (PDMS) composite film was proposed to enhance the electrical output from mechanical movements. By optimizing the concentration of ANb microparticles in the PDMS film, a robust HNG with 5 wt % ANb microparticles/PDMS composite film was found to generate the highest electrical output. The clip-like HNG device demonstrated a voltage output of 340 V and 20 mu A, making it suitable for charging capacitors and powering portable electronics.

Summary: The bainite transformation in medium Mn steels has been experimentally and theoretically studied, and it has been found that the transformation kinetics is slow. However, the introduction of dislocations can significantly accelerate the transformation rate. A new "carbon depletion mechanism" is proposed to explain the role of dislocations in the acceleration of bainite transformation, and a physical model is developed to quantitatively understand the kinetics of bainite transformation.

Summary: Metal-organic frameworks derived composites are promising EMW absorbers. Cation substitution can improve their absorption performance by regulating morphology and atomic space occupation. However, the mechanisms of how cation substitution affects EMW absorption performance are still not well understood. In this study, imidazolic MOFs were fabricated and tailored by cation substitution strategy to prepare porous composites. The samples showed optimal reflection loss and effective absorption bandwidth values under low filling rate and thin thickness conditions. The intercoupling between multiple atoms and the porous structure introduced by cation substitution contribute to the improved absorption performance.

Summary: A simple one-step anticorrosion coating with an autogenerated oxide film on the surface of Mg alloy was successfully prepared in this study. The corrosion resistance of the coated Mg alloys was significantly enhanced due to the synergetic effect of the coating and autogenerated oxide film. The quality of oxide film played a dominant role in determining the anticorrosion of Mg alloy. The addition of metakaolin and dolomite improved the resistance of the coating and the quality of the oxide film.
