Figure 1 shows the TGA curves of two samples with different LW content.
Compare with the two TAG curves in figure 1, the lower LW content sample presents larger value.

Stoichiometric amounts of Al(NO3)3.9H2O and Mg(NO3)2.6H2O are mixed in such a way that the Al AND Mg ratio is maintained at 2:1.A small amount of water is added to it to form limpid solution.
Figure 1 shows the flow chart of the procedure used for the preparation of MgAl2O4 powders.
Conclusion (1) Preparation of nanocrystalline MgAl2O4 powders using polymer gel reaction is technically simpler, more cost effective, and more time and energy efficient than other technology

The molar ratio of the above reactants was as follows: (1-0.3) NiCl2. 6H2O:0.3 CoCl2.6H2O:1.0H3PO4:3.0 TEA:200H2O (where the molar ratio of cobalt in the overall metal was 0.3).
[Fig. 1] The powder XRD pattern and SEM techniques revealed the as-synthesized novel cobalt-nickel phosphate CoNiPO4 exhibited high crystallinity and homogeneous morphology ([Fig. 2], typically a stacked sheet shape).

Introduction With the increasing demand for wireless services, existing fixed spectrum assignment policies [1] have led to a serious deficiency in valuable spectral resources.
System Model As in Fig.1, we consider a multiuser MIMO CR system composed of K secondary users and one primary user.
It’s assumed that each user has nT=12 transmit antennas and nR=3 receive antennas, the maximum transmit power for each transmitter is Pk=1, and the maximum tolerable interference power is PSU,k=0.1.
