Temperature saturation vector

The ESR measurements were conducted after evacuation of the catalysts at various temperatures (RT to 723 K) and after NO adsorption at RT. ESR spectra were recorded at 77 K on a RADIOPAN SE/X 2547 spectrometer. The patterns were obtained at vESR = 8.9 GHz FTIR study was performed using a VECTOR 22 (BRUKER) spectrometer The self supported discs of 10 mg cm 2 of the catalysts were activated under vacuum at 723 K Pyridine was admitted at RT and after saturation the samples were degassed at RT, 423, 523, and 623 K in vacuum for 30 min. [Pg.814]

The behavior of the low temperature Elc polarized emission spectrum of a typical MCP salt, BaCP, for different magnetic field strengths is presented in Fig. 4394). The vector orientation is H c, HIO and Ole, where O denotes the direction of observation. A relatively large blue shift of the peak maximum of the Elc emission by —270 cm-1 (Fig. 44) and a drastic increase of the intensity (Fig. 45) are observed as the magnetic field is raised from 0 to 6 T. Above = 3 T the spectral position of the Elc emission remains nearly constant, whereas no saturation effect of the intensity growth is found up to 6 T. If the excitation wavelength is changed from 364 to 458 nm the increase in intensity is lowered by a factor of 3. [Pg.141]

Fig. 2. Distribution of glutaminase-like immunoreactivity in the central nervous system. The rat brains were fixed and immunostained as reported before (Kaneko et al., 1989). Briefly, rats were fixed at room temperature by transcardial perfusion of 0.2% formaldehyde, 75%-saturated picric acid and 0.1 M sodium-phosphate, pH 7.0, and the brain blocks were further placed for 3 days at 4°C in 2% formaldehyde, 75%-saturated picric acid and 0.1 M sodium-phosphate, pH 7.0. The brain sections (30 p.m thick) were incubated with 10 p.g/ml monoclonal anti-glutaminase IgM, MAb-120, then with 10 p.g/ml biotinylated goat anti-glutaminase antibody (Vector), and finally with avidin-biotinylated peroxidase complex (ABC Vector), and the bound peroxidase was developed brown by reaction for 10-30 min with 0.02% diaminobenzidine-4HCl (DAB), 0.003% H2O2 and 50 mM Tris-HCl, pH 7.6.

Let us go back to the discussion of the Frederiks transition in a homogeneously oriented nematic with positive dielectric anisotropy (splay distortion). A conventional sandwich cell is used which is very convenient in this case, because the Kerr effect is not observed when the light wave vector coincides with the field direction. Let us imagine that we are measuring the temperature dependence of the anchoring energy of the nematic using the saturation field for the complete director reorientation. For 5CB we have the left part of Fig. 4.39 [226]. [Pg.207]

At this point in the problem, we are interested in the ratio of heat transfer to area. To do this, we calculate the temperatures of saturated steam at our pressure guess vector values via linear interpolation of the steam table data and calculate a vector of fluxes... [Pg.184]

Fig. 3 A two-phase flow simulation in PEMFC based on MMM. Water saturation distribution and gas phase velocity are expressed by color scale and vector, respectively. The typical water saturation distribution, where a large water saturation region appeared in the GDL near channel outlet, is caused by the water production at cathode catalytic layer, and by its accumulation along flow channel. The gas phase velocity in the flow channel is larger than that in the GDL, and is almost constant in the stream-wise. The calculation condition used are cell temperature is 80 C, average current density is 1.0 A/cm, hydrogen and oxygen utilization ratio is 0.5, humidifler temperature for anode and cathode is 60 and 25°C, respectively.
