The synthesis of nontoxic stable gold nanoparticles is important for medical applications. An aqueous extract of the plant Stachys lavandulifolia Vahl was used to synthesize gold nanoparticles. This green method involved the S. lavanduhfolia Vahl extract acting as a reducing and stabilizing agent. The nanopartides were characterized by transmission electron microscopy, dynamic light scattering analysis and UV-vis absorption and Fourier transform-infrared spectroscopies. Stability under physiological conditions, is important for medical applications. The stability of the nanoparticles was compared with that of conventional citrate-capped nanoparticles, under both synthetic and physiological conditions. The nanoparticles synthesized from the S. lavanduhfolia Vahl extract were stable under physiological conditions, in contrast with conventional citrate-capped nanoparticles.

Polarized imaging dynamic light scattering for simultaneous measurement of nanoparticle size and morphology
Bingyao Wang, Tianyi Cai, Xiaoshu Cai, Wu Zhou, Zeqi Liu
Summary: The size and morphology of nanoparticles significantly impact their performance. Current methods, such as electron microscopy or atomic force microscopy, have limitations in sample preparation, processing time, and quantitative characterization. Therefore, it is crucial to develop a fast, accurate, and statistical method for measuring nanoparticle size and morphology. In this study, a new method called polarized imaging dynamic light scattering (PIDLS) is proposed, which irradiates nanoparticles with a vertical linearly polarized laser beam and utilizes a polarization camera to collect dynamic light scattering images at different polarization directions. The method effectively determines particle size, morphology, and sphericity based on depolarization patterns and degree of linear polarization. PIDLS also enables simultaneous measurement of particle size and morphology distributions, allowing for the evaluation of particle uniformity. The effectiveness of PIDLS is validated with the measurement of five types of industrial titanium dioxide.

Qingye Meng, Shuangling Zhong, Jingfei Wang, Zhenqian Zhang, Yan Gao, Xuejun Cui
Summary: In this study, a non-toxic natural polysaccharide, sodium alginate (SA), was developed for targeted delivery of curcumin (CUR) in tumor therapy. The CUR was coated in microcapsules using a quick, efficient, and environment-friendly sonochemical method. The microcapsules showed similar toxicity to free curcumin in anti-tumour evaluation and exhibited effective antibacterial properties. This research has the potential to provide a low-cost tumor targeting vector and can be promoted for clinical application.

Soft coarse-grained particle model for particle-fluid systems
Yanhao Ye, Ji Xu, Wei Ge
Summary: By modeling neighboring particles as a single coarse-grained particle, the discrete particle method (DPM) can now simulate industrial-scale particle-fluid systems. However, there is still a lack of a systematic approach to determine the properties and interaction models of these coarse-grained particles, which affects the predictability of the method. In this study, kernel functions for modeling the coarse-grained particles are constructed based on the analysis of collisions between predefined particle groups, and the model parameters are determined by equating the statistical properties of the coarse-grained particles to those of the real particles. This approach has been effective in simulating the homogeneous cooling of granular gas and experimental fluidized beds.

A refined representation method of the particle size distribution curve based on grading entropy
Xing Li, Qun Chen, Zhaozhao Liu, Cheng Zhou, Chen Wang, Chen Chen
Summary: The particle size distribution (PSD) curve is an important expression of soil properties. However, existing characteristic parameters can only represent some points of the curve and fail to capture all the information. This paper introduces a new fraction characteristic parameter based on grading entropy and proposes a refined presentation method for the PSD curve. The new method not only represents the differences in curve width more accurately but also has higher discrimination ability. The application of this method in describing deposit distribution and predicting soil hydraulic conductivity is discussed. The research results can provide reference for the refined representation of PSD curves.

Temperature influence on minimum fluidization velocity: Complexity, mechanism, and solutions
Qingjin Zhang, Liangliang Fu, Guangwen Xu, Dingrong Bai
Summary: This study comprehensively analyzes the temperature effect on the minimum fluidization velocity (Umf) in fluidized-bed reactors. The analysis reveals the influence of temperature on Umf is determined by the relative importance of hydrodynamic forces and interparticle forces, which result in changes in gas properties, bed voidage, and physiochemical characteristics of particles. An equation is derived to predict the temperature influences on Umf under broad temperature conditions.

Hydrodynamics and OCM reaction performance in a bubbling fluidized bed reactor and a riser reactor
Min Cai, Shuangzhu Kong, Sheng Chen, Mengxi Liu, Chunxi Lu
Summary: Reasonable reactor design is crucial for increasing the C2 yield in the oxidative coupling of methane (OCM). This study focused on large-scale fluidized bed reactors and conducted experiments and simulations to investigate their hydrodynamics and reaction performance. The results showed that the consecutive reactions of ethylene were severe in the bubbling fluidized bed (BFB) reactor due to gas back-mixing, high solids holdup, and non-uniform solids distribution, while they were negligible in the riser reactor. Both reactors achieved isothermal operation for the OCM process, with the riser reactor showing higher C2 selectivity and yield compared to the BFB reactor. This study provides valuable information for OCM reactor design and commercialization.
