One of the most fascinating enigma in modem astrophysics concerns the true nature of the ultra-dense compact objects called neutron stars. Different models for the EOS of dense matter predict a neutron star maximum mass (Mmax) in the range of 1.4 - 2.2 M , and a corresponding central density in range of 4 - 8 times the saturation density (po 2.8 x 1014g/cm3) of nuclear matter (e.g. Shapiro Teukolsky 1983 Haensel 2003). In the case of a star with M 1.4 Mq, different EOS models predict a radius in the range of 7 -16 km (Shapiro Teukolsky 1983 Haensel 2003 Dey et al. 1998).

Special attention has been paid to acid-catalyzed ring expansion. Sterba and Haensel (J19) reported that the rate of benzene formation from methyl-cyclopentane increases with increasing fluorine content of the catalyst (up to 1.0% F with 0.3% Pt on alumina). At the same time, increasing platinum content also promoted this reaction (up to 0.075% Pt with 0.77% F on alumina). This indicates the remarkable cooperative action of a dual function catalyst (119, p. 11). 

Haensel and Haensel [2] describe the criticaUty of the role of catalyst characterization in process and catalyst development They conclude that catalyst characterization is the cornerstone for the science of catalysis and for industrial progress. They emphasize that the characterization must have a purpose and be targeted for understanding and solving a specific problem in order to achieve commercial success.
