Full textWe address the problem of recognition and growth of ice nuclei in simulation of supercooled bulk water. Bond orientation order parameters based on the spherical harmonics analysis are shown to be ineffective when applied to ice nucleation. Here we present an alternative method which robustly differentiates between hexagonal and cubic ice forms. The method is based on accumulation of the maximum projection of bond orientations onto a set of predetermined vectors, where different terms can contribute with opposite signs with the result that the irrelevant or incompatible molecular arrangements are damped out. We also introduce an effective cluster size by assigning a quality weight to each molecule in an ice-like cluster. We employ our cluster analysis in Monte Carlo simulation of homogeneous ice formation. Replica-exchange umbrella sampling is used for biasing the growth of the largest cluster and calculating the associated free energy barrier. Our results suggest that the ice formation can be seen as a two-stage process. Initially, short tetrahedrally arranged threads and rings are present; these become correlated and form a diffuse ice-genic network. Later, hydrogen bond arrangements within the amorphous ice-like structure gradually settle down and simultaneously `tune-up¿ nearby water molecules. As a result, a well-shaped ice core emerges and spreads throughout the system. The process is very slow and diverse owing to the rough energetic landscape and sluggish molecular motion in supercooled water, while large configurational fluctuations are needed for crystallization to occur. In the small systems studied so far the highly cooperative molecular rearrangements eventually lead to a relatively fast percolation of the forming ice structure through the periodic boundaries, which inevitably affects the simulation results.

In this study, we performed an optimized parameter search of the eflucimibe polymorph nucleation mechanism. This mechanism uses gradual disruption theory as a theoretical background to calculate the induction period. A comparison of the average relative errors was then conducted with the eflucimibe polymorph induction period experimental data obtained from literature. The combination of parameters with the lowest average relative error was the optimal parameter. Eflucimibe forms A-form and B-form polymorph crystals. Their relative nuclear rates determine the final crystal form obtained. Therefore, the nucleation mechanism’s influence on eflucimibe is extremely significant. The aggregation and disruption mechanisms in gradual disruption theory use Smoluchowski’s aggregation theory. Then, because clusters smaller than critical nucleus size have unstable thermodynamics, they gradually dissolve and are disrupted. Although this theory comprises only aggregation and disruption parameters, the nucleation rates of dozens of clusters of varying sizes are interrelated. Thus, appropriate nucleation parameters are difficult to speculate. We employed optimization algorithms to identify the optimal nucleation parameters and investigate whether gradual disruption theory is consistent with eflucimibe nucleation mechanisms. The optimization system used in this study had virtually no restrictions, its search range was extremely broad. To increase the search efficiency, we divided the system into several search ranges. Genetic algorithms and the random jump method were used to seek lower average relative errors. Subsequently, the parameter combinations with lower average relative errors were used as Nelder-Mead Simplex Method starting points to obtain the minimum average relative error values. Following analysis and comparison of the parameter combinations in each range with lower average relative errors, ranges where optimal parameters may exist were suggested. Using this method, the optimal parameter values were identified. Numerous divergence points are typically encountered when seeking optimal parameters due to a lack of understanding of the objective function surface characteristics. This leads to poor genetic algorithm search efficiency. The Nelder-Mead Simplex Method follows function surface decreases and can efficiently avoid divergence points. Additionally, it does not require prior understanding of the search space and is suitable for use in this study’s optimization system. Therefore, the most appropriate algorithm combination for this study is the random jump method matched with the Nelder-Mead Simplex Method. Finally, we successfully obtained the optimal nucleation parameters kA: 3.62 10-21(cm3/s), kB: 5.92 10-21(cm3/s), kd,A: 8.61 10-2(1/s), and kd,B: 17.15 10-2(1/s), and the minimum average relative error of 8.15%.

In this period of technological development, portable electronics and electric vehicles are gradually booming. Many manufacturers also pay more attention and research on this field of lithium batteries. Lithium secondary batteries have some advantages like higher energy, higher power, lighter weight and longer life. Demand for lithium battery safety is the most important product assessment project in the batteries market, and the separator is the most important element. Its main function is to isolate electron and avoid a short circuit between the positive and negative electrodes. When the batteries’s temperature rises, the separator needs to close the micro-porous holes to prevent the increasing temperature to cause an explosion. Therefore, the lithium battery ‘s separator quality indicators are strength, thickness, pore distribution and thermal shutdown. They decide the capacity of the battery, the battery cycle life and safety. As a result, lithium battery separators attract a lot of attention on the future market development. Plastic’s nuclei can be called “seeds” which can produce a crystalline substance. Nucleating agents are usually added in the plastic in order to accelerate the growth of crystals. The method can increase the crystallizing point, make the crystallization much smaller, avoid producing big spherulites and make the growth of the spherulites more regular. We experimented on PP and PE. First, we compounded the plastics and nucleating agents to be mixtures. The key point is compound dispersion. Second, we used blown film, annealing and tensile test processes to make the micro-porous membrane. This experiment through changing resin crystallization’s behavior so that the nuclei can adsorb the polymer chain in the melt effectively. The spherulites will become small and dense particles, then the size will arrange more uniform and regular. So that we can use the tensile test to produce the micro-porous structure. It will achieve the development of lithium battery separator that has high mechanical strength and high porosity properties. The main purpose of this research is to develop the technology which uses the twin-screw extruder machine to compound the plastic materials with different types and proportion nucleating agents. Then, we used the compound materials to prepare the membrane by the co-extrusion blowing film process with high tensile speed ratio. Finally, we use the second stretch process and different blown process parameters on the MD direction to produce the micro-porous membrane. The micro-porous membrane thickness is 10-30 µm. It’s micro-porous scale is in the 50~500 nm range and high mechanical strength. The PP micro-porous should be closed when the temperature increases. On the second stretch process, we can adjust the stretching parameters like the annealing, cold-drawn, hot-drawn and heat setting conditions. Then we investigated the film's mechanical strength, porosity, pore size, heat shrinkage and thermal shutdown temperature to know the best parameters on the experiment. Furthermore, we can compare the membrane detection result with the Celgard company’s membrane result to know the quality and the direction of improvement. This is the main focus of this study. From the experimental results of the second stretch process, we can know adding nucleating agent will change the pattern of crystalline arrangement. It also will cause the different between the adding nucleating’s separator and the blank separator. From the directions of different blow process parameters, breathable property and microporous’s pattern, we can know some experimental trends. For example, when we increase the DDR and the cooling speed, the separator’s breathable property will improve and the pore distribution will more uniform, too. In addition, when we add the nucleating agent in the separator, it can let the crystallization smaller and much evenly. Adding nucleating agent will let PP, PE and PP/PE/PP separator have the uniform types of microporous. Then these separators can accordance with industry standards of breathable property and mechanical strength. Nevertheless, some properties like shrinkage and thermal shutdown’s temperature still cannot accordance with industry standards . These trends are also our future’s research direction.
