(called the G band) corresponds to the stretching vibration mode with E2g symmetry in the aromatic layers of the graphite crystalline, whereas the latter (called the D band) represents disordered graphite or glassy carbons.32 As shown in Fig. 8, each spectrum was subjected to peak fitting using the curve fitting softwa...

In a collaborative effort, Priestley and Cangialosi investigated the segmental dynamics and To of PS nanospheres using CD and DRS, respectively [64]. Here, a film of dried PS nanospheres was prepared between Au electrodes using a Teflon spacer. The films were dried under vacuum at room temperature to remove residual wa...

The complex impedance plot of PVP:KBrO4 (95:05) polymer electrolyte at different temperatures is shown in Fig. 5. This figure shows two well defined regions; a high frequency semicircle related to the parallel combination of a resistor and a capacitor and a low frequency spike representing formation of double layer cap...

Fig. 1. (A) Cole-Cole plot for (a) 90CA:10NH4NO3, (b) 80CA:20NH4NO3, (c) The ionic conductivity of BPEs depends on several factors, such as ionic conducting species, types of charge carriers (cationic or anionic) and the temperature. The evolution of the typical impedance plot (Z' and Z") as a function of variation in ...

Thermal evolution of lattice parameters of the BisTi3FeO15 and BigTi3Fe2O18 compounds are shown in Fig. 3. The transition temperature from orthorhombic phase to tetragonal phase is about 1021 K for BisTi3FeO15, and about 973 K for BigTi3Fe2O18, in good agreement with those of the LT transitions determined by DSC. The H...

Fig. 18. A systematic change of 18.2 nm diameter CPG to cyclohexane mass ratio provides a quantitative measure of the total pore volume Vo from the slope and the liquid density. The thermoporometry value, 1.11 cm3/g, compares favorably with the stated Hg intrusion value of 0.97 cm3/g, cf. Table 2. concentration series,...

(Fig. 1 A and B). These results verify previous reports (7-9) and extend their findings by showing that cold acclimation does not appear to be an essential prerequisite for attaining high freeze tolerance. We found that reaching the appropriate stage of diapause development [i.e., transition from initiation to maintena...

By considering the phase structure of PLLA/POM blends quenched from the miscible region, the double T depressions have been attributed to the negative pressure resulting from differential contraction due to the thermal expansion mismatch between PLLA and POM phases, as shown in Figure 10. The PLLA/POM blends are homoge...

The plots of Fig. 15 provide the x dependence of lineshape parameters of CM. For the CM, we had noted that the majority mode frequency (CMhish) is, in general, higher than the minority mode (CM(0") frequency. The normalized scattering strength ratios of the majority and minority CM appear in Fig. 15(b), and as expected...

(see Figure 5c below). The shorter PET polymer chains could have fold among themselves and rearranged into intercrystalline domains resulting in a higher crystallinity compared to the physically aged samples.[27] and CP-PET at different stages of enzymatic degradation are shown in Figure 5a,b. Both spectra of the untre...

The enthalpy change (AH) associated with these processes can be calculated by the integral of the heat capacity over the temperature range, as observed in the DSC thermogram peak (Fig. 1): The temperature-dependent heat capacity curve of a lipid bilayer, obtained using DSC, can provide insights into the phase behavior....

DSC provides information on the temperature dependence of the excess apparent specific heat over a wide temperature range (Cp vs T curves, Fig. 1). This allows the determination of the thermodynamic functions for well defined molecular systems.
