As a cross-validation, the chemical Li* diffusivities for Li[NixCoyMnz]O2 (x = 1/3, 0.5, 0.6, 0.7 and 0.8) were measured by the galvanostatic intermittent titration technique (GITT) [18]. As can be seen in Fig. 8, the Li* diffusivity increased with increasing Ni content (x) i...

Figure 3 presents the dependence of the glass transition temperature and fictive temperature on heating/cooling rates together with the linear regression line. The slope gives the apparent activation energy, Ea. Good linearity is observed between the Tx and heating/cooling rates. The heating and cooling modes lead to s...

For clarity, the double logarithmic plot of the frequency dependence of the real part of the ac conductivity at two selected temperatures is displayed in Fig. 9(a,b). As can be seen, each curve displays conductivity dispersion, which is strongly dependent on frequency and temperature. o'(f) increases monotonically with...

Thermal degradation measurements were carried out in the temperature range of 25-600 ℃ for SKF 32, F-32L, KeL-F, FK 800 and FKM under nitrogen atmosphere. Figure 4 shows TG and its corresponding DTG curves. TG/DTG Fig. 4 TG and its DTG curves of SKF 32 (long dashed lines), F-32L (long dotted dashed lines), KeL-F Figure...

where A and B are constants. The value of A gives information about the glasstransition temperature for a heating rate of 1 K · min-1. It has been found by various researchers that the value of B in Eq. 5 is related to the cooling rate of the melt; the lower is the cooling rate of the melt, the lower is the value of B....

Figure 5 summarizes our DSC results of glass transition temperature of cellulose with different water contents (triangles). The results are shown together with the experimental curve (dashed line) of Batzer and Kreibich (1981) and that calculated (for cellulose of 0, 55, and 80% crystallinity index) by Salmén and Back ...

Using our DSC data as well as information from more recent PC/cholesterol spectroscopic studies [17,31] we propose a revised form of the DPPC/cholesterol 'phase diagram' (or perhaps more accurately a temperature/composition diagram) in Fig. 8. Similar to the majority of prior

Alamar Blue assay uses resazurin reduction to red fluorescent dye resorufin by live cells through cell metabolism. In Fig. 7, the cell toxicity of KP3 group increased significantly after arriving at the concentration of 0.1 mg/ml, while for the KP5 group, this turning point appeared at the concentration of 1 mg/ml. The...

The corrosion behavior of real epoxy systems was investigated by the EIS. In the sodium chloride solution pure epoxy coating showed no indication of corrosion, even after 100 days of immersion, so the corrosion was investigated in more aggressive 0.1 M H2SO4. From Fig. 11, where the dependence of the impedance magnitud...
