Wetting Behavior of Polymer Droplets: Effects of Droplet Size and Chain Length [PDF]

open access: yesMacromolecules, 2018
Monte Carlo computer simulations were utilized to probe the behavior of homopolymer droplets adsorbed at solid surfaces as a function of the number of chains making up the droplets and varying droplet sizes. The wetting behavior is quantified via the ratio of the perpendicular to the parallel component of the effective radii of gyration of the droplets

Self-organized criticality driven by droplet influx and random fusion

open access: yesPhysical Review Research
The droplet size distribution typically decays exponentially in solutions formed by liquid-liquid phase separation. Nevertheless, a power-law distribution of nucleolus volumes has been observed in amphibian oocytes, which appears similar to the cluster ...

Droplet Size Distribution in Spray

open access: yesChemical engineering, 1969
スプレーノズル先端で形成される薄膜の激粒化過程をランダム・ウォークモデルから考察し, 生成される液滴の粒径分布が対数正規分布となることを示した。さらに最大粒径を考え, 反射壁のあるランダム・ウォークを用いて対数正規分布を補正すれば, 実測値とよい一致を示すことが判った。平均粒径は, 最大粒径と対数標準偏差とから容易に計算できる。
