The compatibility limit of DOP in PEO was about 15 wt% in the preparation conditions of these samples.
Variation in the preparation conditions showed that the rapid temperature increase was necessary to obtain form III. This allows the assumption that the crystallization in the oven occurs at the hot solid substrate further allowing the thermodynamic unstable polymorph to be entrapped and stabilized at the silica substrate even without the exclusion of air.
In the optimal preparation condition (825 °C/96 h + 990 °C/3 h), these glass-ceramics exhibited a high crystallinity (87.3 vol. %), high transmittance (78%), and excellent mechanical properties.
In this preparation under control conditions, Ca2+ sparks occurred with a frequency of 2.6 ± 0.1 Hz/spark site (n = 105 spark sites), with a rise time of 17 ± 0.3 ms and a time to half decay of 21 ± 0.7 ms (averaged from 4,103 sparks recorded from 105 spark sites).
In this work, the preparation conditions are same for bulk-Fe2O3 PEG400 bulk-Fe2O3 PEG400-PEG400 nanofluid; the two mand differences are the particle size of Fe2O3 in these fluids and interaction of PEG with the surface of γ-Fe2O3-PEG400rtheles which can be higher twon the surface of bulk-Fe2O3.
It is notable that we do not observe morphological changes with changes in either of these preparation condition variables.
In the best preparation conditions, the electrocatalytic activity of the Pt Ru/C catalyst prepared in the ionic liquid for methanol oxidation is higher than that of the commercial E-Tek Pt Ru/C catalyst.
This could be due to the differences in the sample preparation conditions as it seems Nishiyama et al. have collected all the portions from the train sublimations whilst we have collected the portions from a hot region (~170°C) and near the sublimation boat.
However, under the preparation condition, the error in low-order mode is about 10%%, which is acceptable for engineering requirements.
The physical properties of the films are investigated in terms of the preparation conditions, such as Fe2O3 content in the target, RF power, substrate temperature and working pressure.
