In this study, Pt/AliOj having high activity for CO oxidation and different affinities for fee adsorption of CO and Hi was selected as a catalyst/adsorbent In a conventional packed bed reactor (PBR), fee surface of fee catalyst is dominantly covered by COads with small amotmt of Oads fee CO conversion is therefore low. Several investigations on periodic operation have illustrated feat fee reaction front wife comparable amount of fee two adsorbed species leads to enhancement of fee CO conversion. Conceptually, this type of the reaction front should be generated by application of a CMBR, as well. Figure 1 illustrates an image of... 

The correlations between Dg and 1/p for PNP and PCP obtained in DR and CMBR are presented in Figure 2, indicating that the apparent diffusivity is a strong function of the adsorbate molecule and temperature. 

From Equation (3), the value of the surface diffusivity Ds were calculated by subtracting the pore-diflusivity term Dp/Ppp from the apparent diffusivity D . The value of Ds/De is then plotted against D for DR and CMBR methods (Figure S-a) and for LCB method (Figure S-b). It can be pointed out from Figure S-a that that (i) DR and CMBR methods yield similar estimate of D, and that (ii) intraparticle diffusion of PCP into GAC is dominated by surface diffrision compared to PNP. 

It is also seen from Figure S-b that the extents of Ds contribution to D evaluated on LCB method almost coincides with those for DR and CMBR, implying that LCB method can be applied for the determination of concentration dependency of D .

Cosmic microwave background radiation (CMBR) is the oldest light we can see. It is a snapshot of how the universe looked in its early beginnings. First discovered in 1964, CMBR is composed of photons which we can see because of the atoms that formed when the universe cooled to 3000 K. Prior to that, after the Big Bang, the universe was so hot that the photons were scattered all over the universe, making the universe opaque. The atoms caused the photons to scatter less and the universe to become transparent to radiation. Since cooling to 3000K, the universe has continued to expand and cool.

The information concerning the constitution of the early Universe has increased tremendously during the past decade, mainly due to improved observations of the cosmic microwave background radiation (CMBR). The most important cosmological parameters (the total energy density, the part contained in baryonic matter, the part of nonbaryonic dark matter (DM), other components, etc.) have been determined with percent level accuracy as a result of projects completed in the first decade of the twenty-first century and now appear in tables of fundamental physical data (Amsler et al. 2008). 

The first quantitative evidence for the temperature anisotropy of CMBR was provided by the COBE (Cosmic Background Explorer) satellite in 1992. The angular resolution of its detectors was 7°. This enabled the collaboration to determine the first 20 multipole moments of the fluctuating part of CMBR beyond its isotropic component. It has been established that the degree of anisotropy of CMBR is one part in one hundred thousand (10 ). There are two questions of extreme importance related to this anisotropy ... 

Following the success of the COBE mission several more refined (ground based and balloon) measurements of the CMBR fluctuations were performed between 1998 and 2001. An angular resolution of about 1° has been achieved, which was further refined to the arc-minute level by the satellite mission Wilkinson Microwave Anisotropy Probe (WMAP). The combined efforts of these investigations allowed the determination of the multipole projection of CMBR on the sky up to angular moments I = 2,000. The fluctuation information extracted... 

Another important characteristic of the CMBR anisotropy is its spectral power distribution. The measured distribution is nearly scale invariant it is the so-called Zel dovich-Harrison spectrum (see Peebles 1993). This means that every unit in the logarithm of the wave number contributes almost equally to the total power.
