New method for the spin quantitation of [[4Fe-4S].sup.+] clusters with S = 3/2: application to the FS0 center of the NarGHI nitrate reductase from Escherichia coli
Article Abstract:
The article describes a new method for carrying out the spin quantitation of electron paramagnetic resonance (EPR) signals given by [[4Fe-4S].sup.+] clusters with S = 3/2 species, which is applied to the g = 5 signals displayed by NarGHI nitrate reductase. The results have shown that the simple analyses based on the assumptions of an isotropic g matrix can give rise to very large errors.

Multitechnique investigation of the physisorption and thermal treatment of mixed-metal clusters on carbon
Article Abstract:
The three clusters [RU6PtC(CO)16(COD)], [Ru5PtC(CO)14(COD)] (COD = 1,5-cyclooctadiene), and (NEt4)2[Pd6Ru6(CO)24] were physisorbed onto an active carbon support and used as molecular precursors for supported particles. It was found that the clusters are molecularly intact, but present in the form of agglomerates on the support at the end of physisorption step.

Polymorphism of even-numbered carbon atom n-alkanes revisited through topological P-T diagrams
Article Abstract:
The phase relationship of metastable orthorhombic phase and stable triclinic (T) phase for even-numbered carbon atom n-alkenes is investigated using toplological pressure-temperature (P-T) diagrams. The orthorhombic phase is found to show no stable phase region irrespective of the temperature and pressure.
