Therefore, the high temperature spectrum in Fig. 8a was fitted in a reduced frequency range (omitting the lowest frequency points) – in Fig. 8b and c the frequency points used for this reduced range fit are indicated by the filled red circles.
Measured temperatures are believed to be accurate to within ±1 K, and temperature stability during data collection is better than ±0.1 K. High-temperature spectra were collected with the sample balanced across a pair of corners between the tips of two alumina rods protruding into a horizontal tube furnace.
The high-temperature spectrum, recorded on the same sample at 220 K, is also shown in Figure 3 along with its simulated spectrum (bottom spectra).
Figure 1C shows the TDS spectra obtained by subtracting the low temperature (15°C) spectra from the high temperature (95°C) spectra (data not shown), with the TDS displayed as the difference between the folded and unfolded forms at temperatures well below and above the corresponding Tm (Figure 1D), respectively [11]. Figure 1D shows the normalized folded fraction curves of the Pu39WT G-quadruplex.
The space charge effect dominates the high temperature dielectric spectra.
Because hydrogen fluoride molecules break down at high temperatures, the spectra of warmer stars show less of the gas than those of cooler ones do—even if the warmer stars contain just as much fluorine.
Even at high temperatures, ECD spectra of LmCld show mainly intact secondary structural elements that differ from very uncommon minima of SaCld in the far UV region [10].
Furthermore, two kinds of alkyl-branching signals were detected in the high temperature 13C NMR spectra of EVA copolymers.
At least three Arrhenius-type activation energies can be extracted from the plot in Fig. 5:,, and quite satisfactorily agrees with the energy 38 meV extracted from the high temperature difference PL spectra (Fig. 4) for the e1 → hh2 transition.
Interest in thermophilic bacteria as live-cell catalysts in biofuel and biochemical industry has surged in recent years, due to their tolerance of high temperature and wide spectrum of carbon-sources that include cellulose.
Higher temperature TSDC spectra (250 350 K) provided the α relaxation peaks associated with the glass transition temperature.
