Clearly, the spectroscopic properties of the P clusters in the proteins do not reveal their structural nature. However, extrusion of these clusters from the protein leads to the clear identification of 3-4 Fe S clusters(13.291. Despite the uncertainties inherent in the extrusion procedure (due to possible cluster rearrangement) the extrusion result supports the Dominant Hypothesis, which designates the P centers as Fe S units, albeit highly unusual ones. The P clusters are thought to be involved in electron transfer and storage presumably providing a reservoir of low potential electrons to be used by the M center (FeMo-co) in substrate reduction. 

One should take notice of an unusual Co + ion extrusion procedure from the [Co(diAMHsar)] + cage using an 8-hydroxy quinoline that was described in Ref 177. The resulting ligand readily encapsulated nickel and copper(II) ions to produce octahedral complexes. 

Eor PA/ABS blends, e.g., Alphaloy MPA, Elemid , Diaaloy N, Kane ace MUH, Malecca S, Maxloy A, Monkalloy N, N5, Novaloy -A, Stapron N, SX, Techniace TA, Toyolac Adloy, Triax 1000, Ultramid ), single or twin screw extruders are suitable. However, the latter are preferred. Typical ABS extrusion procedure should be followed. Eor two-stage screws, a first stage compression ratio of 25-2.1 and pump ratio 1.5-2 are recommended. 

The collection of diffraction data of polymers in a solid mesophase for the structural analysis is generally performed on imiaxially oriented samples (fibers) [152-154]. Oriented fibers of high polymers in a mesomorphic form may be easily obtained by extrusion procedures from solution or melt and/or by cold stretching procedures. 

In comparison to AES prepared in the polymerization, AES prepared by grafting SAN in the extrusion procedure may reduce the manufacturing cost by simphfication of the procedures, but has the disadvantages that...
