By exploiting the coherent explanation how actors form alignments in a game provided by the landscape theory......
, extensive aggregation between Sn nanoparticles was observed after drying. However, the aggregation behavior did not further influence the melting point, because actual agglomeration did not occur in the aggregates. Key words: tin nanoparticle; melting point; centrifugation; agglomeration; aggregation 1 Introduction With the growing interest in nano-materials, extensive studies have been conducted......
method compared with the analytical solution. Key words: population balance equation; particle density distribution; growth; aggregation 数群平衡模型(population balance model, PBM)主要用于研究离散系统中颗粒粒度分布函数的时间演变过程[1... method was used to calculate the population balance equation, and growth and aggregation processes were involved in the population balance equation. Population balance equation was transformed......
aggregation. AFM experiments showed that DNA-induced particle aggregation originated from the strong interactions between DNA and Au-NPs, that is, the adsorption of DNA onto the Au-NPs surface would result in particle aggregation. After a short period of time, the Au-NPs were easier to aggregate in the presence of the higher concentration of DNA. At the early stage of incubation, the DNA double helix......
(PBE), and the effects of breakage and aggregation on probability of ice particle size distribution and average particle size were analyzed. The results show that both breakage and aggregation have important but opposite effects on the size distribution and evolution of ice particle during storage, and the processes of ice slurry storage include breakage-aggregation in equilibration......
is the best method. The nanometer α-Al2O3 powder with non-aggregation can be manufactured using n-butanol azeotropic distillation and the average particle size is about 40 nm. key words: nanometer α-Al2O3... and the distribution of the particle size is inhomogeneous. The size of α-Al2O3 particles is large and the particles also have a visible aggregation with sintering neck. There might be two......
