Lower annealing temperature

By further controlling the composition of the starting materials, deposition and heating processes, it may be possible to obtain more homogeneous and pure phases of YAP (or YAG) crystalline films coated on alumina core at lower annealing temperatures to avoid forming clusters or coalescing. 

Taking the figures cited above [24], a depression > 3 K for lamellae 15 nm thick when substituted in Eq. 12 with aeo = 93 mj/m2, places ach < 76 mj/m2. This is still a comparatively high figure but it would be reduced if further experiments, at lower annealing temperatures, showed that the hexagonal phase had formed. 

The multilayers were deposited at temperatures ranging from 150-350°C. The t phase appears at 200 °C and ceases to form when deposited at 350°C [8]. The x phase is the only ferromagnetic phase of MnAl and hence for the two deposition temperatures for which the phase is formed there is a development of coercivity. Reports in the literature indicate a coercivity approaching 2 kOe for thin films [9]. As seen in Fig. 15 the coercivity increases up to 3.7 kOe. The formation of MnAl nanoparticles would provide an answer to the problem of agglomeration of FePt nanoparticles due to the lower annealing temperatures required to transform the particles to the FCT. 

We could not amplify the 471-bp fragment from female or male DNA of species from the subfamilies Sigmodontinae, Arvicolinae, or Gerbil-linae. Presumably, our primers, which were designed using the published Mus sequence (subfamily Murinae), were not an adequate match for amplification to take place. We repeated the experiments at lower annealing temperatures but were still unable to amplify Sry in representatives of these subfamilies. 

Because of the closeness of the annealing temperature (150°C) to the temperature of maximum rate of crystallization, both PBT and PET show at this temperature their lowest crystallization half-times. Since the distance from the changing Tg is quite high, the changes in crystallization rate are not as strong as those observed at lower annealing temperatures. 

Below the lower annealing temperature, the rate of stress relief in glass is already so low that permanent stress can no longer occur. The glass can then be cooled at a three to six-fold rate. The same rates can also be employed for heating the ware to the annealing temperature. 

For Case A, the peak area ratio of 25 to (24 + 26) goes from 0.75 at 435 K to nearly 1 at 818 K. The substantial isotope mixing at low temperature shows that molecular emission of intact C2 from the original ethylene molecule does not occur. It is interesting, however, that the isotope mixing is not complete at the lower annealing temperatures. This suggests that proximity of the parent carbons is preserved at low temperature and supports the conclusion that the carbon layer is immobile at temperatures below about 550 K. 

The quantitative application of IMC for the rate of enthalpy relaxation of a pure amorphous APIs and excipients are explicitly documented but unfortunately few examples are available hitherto for ASD (Caron et al. 2010). Exothermic heat flow is detected in TAM below Tg as a consequence of relaxation. During IMC measurement, the early data points are often excluded during data analysis to avoid noise resulting from sample positioning (Kawakami and Pikal 2005). However, IMC records more temporal data points during enthalpy relaxation and hence yields relaxation parameters from a single run when compared to DSC. Thus, the power-time profiles obtained in TAM can be directly treated with the power equations of relaxation models viz., KWW (Eq. 14.3) or MSE equation with respect to time. The derivative form of the MSE equation can describe the experimental relaxation data measured by IMC more consistent, especially those recorded at lower annealing temperature (Kawakami and...
