Summary: The application of the Ozawa-Avrami model to crosslinking polymerizations has some problems, including limited applicability to processes that follow the Avrami model, systematic dependence of temperature on the Avrami index in autocatalytic or decelerating kinetics, inability to accurately calculate activation energy and preexponential factor using the Arrhenius equation, and the possibility of questionable interpretations due to breakpoints in Arrhenius plots.

Summary: The non-isothermal crystallization kinetics of PA6 and ABS blend were investigated using differential scanning calorimeter, showing that the addition of more than 10% ABS in the blend decreases the crystallization rate parameters. The growth of spherulites in the blend system was observed by polarized optical microscopy, and the crystallinity and size of crystallites were measured using X-ray diffractometer.

Summary: This paper investigated the thermal stability and non-isothermal crystallization kinetics of Fe76Ga5Ge5B13Cu1 ribbon, revealing the primary crystallization phase and precipitation of compounds. The calculation of activation energy and analysis of crystallization mechanism suggested that annealing with a higher heating rate can lead to homogeneous nanocrystalline and improved soft magnetic properties.

Summary: Recycled high-density polyethylene (REHDPE)/black shale (B-shale) composites were prepared using a B-shale nucleating agent and polyolefin elastomer (POE) and acrylic impact modifier (ACR) as plasticizers. The effects of the nucleating agent and plasticizer on the melt index, microstructure, mechanical properties, and non-isothermal crystallization behavior of REHDPE were analyzed. The results showed that POE and ACR improved the melt flow rate and interfacial properties of the composites, and B-shale, POE, and ACR synergistically accelerated the crystallization process of REHDPE. The nucleating agent and plasticizer also reduced the crystallization activation energy and enhanced the nucleation activity of B-shale, leading to improved mechanical properties of REHDPE.

Summary: This paper aims to investigate the kinetics of polypropylene (PP) polymer pyrolysis using thermogravimetric analysis (TGA). The results show that the activation energy values for PP polymer pyrolysis at different conversions are in good agreement with the values obtained from four model-free methods. Additionally, the most controlling reaction mechanism identified using Criado's method is the geometrical contraction models-cylinder model.

Summary: The glass transition and crystallization kinetics of lithium-modified zinc borate glasses with different compositions were studied using differential scanning calorimetry. The glass composition of 20ZnO·10Li2O·70B2O3 showed the highest thermal stability and glass-forming tendency among all other compositions. The activation energies for crystallization and glass transition were determined and found to be in close agreement with each other. The formation of a pure monoclinic LiZnBO3 crystalline phase was observed in certain compositions, which has potential for electric double-layer capacitance fabrication.

Summary: This study investigated the kinetics of direct reduction of iron ore with H-2. It was found that higher temperatures led to shorter reduction times and the formation of a dense matrix structure for metallic iron particles in isothermal experiments. The reduction process involved a combination of gaseous diffusion and interfacial chemical reaction mechanisms in the initial stages, and a combination of interfacial chemical reaction and solid diffusion mechanisms in the later stages. In non-isothermal experiments, the heating rate significantly affected the reaction rate, with the reduction proceeding through three stages: mixing control model, two-dimensional diffusion, and three-dimensional diffusion.

Summary: The crystallization kinetics of isotactic homopolymer polypropylene (HPP), impact copolymer polypropylene (ICPP), and their composites were investigated. The Avrami-Jeziorny and Mo models accurately described the crystallization process. The nucleation activity and crystallization rate were influenced by the content of ICPP, with the highest rate observed at 60% ICPP. The changes in chain mobility and crystal-crystal interactions accounted for the fluctuations in crystallization rate and activation energy.

Summary: The kinetics of Juliflora and low-density polyethylene pyrolysis were studied at different heating rates using thermogravimetric analysis, showing that the addition of low-density polyethylene enhances the oil yield and higher heating value. The co-pyrolysis oil has fewer oxygenated compounds and a higher calorific value, indicating better energy utilization efficiency.
