\begin{abstract}

This sample has already become well known for its high value of the Seebeck
coefficient\cite{ref1} and reduced thermal conductivity\cite{ref2}, so being 
a candidate for thermoelectric applications\cite{ref3}. In this paper we 
present transport properties of specially treated sample. The Seebeck 
coefficient $S$ revealed values exceeding 100 $\mu$V/K in the wide temperature 
range, reaching a maximum of more than 500 $\mu$V/K at temperature $T=200 K$. 
The figure of merit 

%----------------------------------------------------------------------
% You can also insert an equation
\begin{equation}
ZT=\frac{S^{2}\sigma T}{\kappa},  \label{eq1}
\end{equation}
is obtained with a help of electrical resistivity $\sigma$ and thermal 
conductivity $\kappa$  measurements. The results point to thermoelectricity 
in the context of strong correlation. We argue that a giant figure-of-merit 
is fingerprint of a heavy quasi-particles liquid with a long mean-free-path. 
Besides its promising thermoelectric performance, this sample exhibit a rich 
variety of interesting ground state properties. At low temperatures the sample 
transforms from a coherent nonmagnetic Kondo lattice to a nonmagnetic single 
ion Kondo system and finally to a superconductor.
