Composition dependence of the viscoelasticity of end-linked poly(dimethylsiloxane) at the gel point

High Performance Thermoplastic/Thermosetting Composites Microstructure and Processing Design Based on Phase Separation

“…The difference between the critical gel at t ps and t gel was noticed that G' is less than G'' at t ps while larger than G'' at t gel as shown in Figure 6 and also reported in other systems (Scanlan＆Winter, 1991). The second difference is in the slop of log G', G'' vs. log ω curves at critical states.…”

“…As shown in Figure 6, at the vicinity of phase separation point t ps and chemical gelation point t gel , G' and G" involve in a parallel manner versus frequency ω in log-log plot, while loss angel factor tan become independent on frequency, implying the characteristic gel transitions, which Winter et al named as critical gel state (Scanlan & Winter, 1991). We will discuss such critical gel behaviors and its applications more systematically in following sections.…”

A new structural biomarker that quantifies and predicts changes in clot strength and quality in a model of progressive haemodilution

“…Fractal analysis is a method commonly used in biology to describe how complex structures develop and perform their specific biological role. [17,18] The incipient clot's fractal dimension, df, was calculated from the frequency independent value of  at the GP using the…”

Sol–gel transition study and pyrolysis of alumina-based gels prepared from alumatrane precursor

“…Table 3 Temperature effect on the gel time, and dynamic properties for pH 9 and h = 9, 18 and 27 Many studies of critical gel rheological properties were found that most results show n ≥ 0.5. Values of n below 0.5 have also been found [23,[26][27][28][29]. Winter reported that if n > 0.5, the gel point preceded the intersection of G and G .…”
