The catalytic effect of metal oxide/alumina whiskers（CeO;, Mn;O;, NiO, Co;O;, Fe;O;, Cr;O;/AW） was evaluated on their ability to drive the nitridation of silicon and to generate mesoporous fibrous silicon *** powder with different particles size along with the catalyst was nitridized at 1300 °C for 5 h in nitrogen and nitrogen diluted with 10 vol% ammonia atmospheres. Nitridation degree of silicon up to 99% was recorded using 1.5 wt% CeO;and Fe;O;catalysts in nitrogen-ammonia atmosphere. The catalyzed samples contain submicronic silicon nitride fibres with a diameter of 400–500 nm and a length of up to few micrometers. The compressive strength of 46 ± 1 MPa was measured for silicon samples catalyzed with nickel oxide/alumina whiskers and nitridized in N;/10 vol%NH;atmosphere. Porous silicon nitride networks were produced with 45–52% porosity, pore sizes in the range of 370–1200 nm and median pore in the range of 495–1655 nm.

A defensive k-alliance in a graph is a set S of vertices with the property that every vertex in S has at least k more neighbors in S than it has outside of S. A defensive k-alliance S is called global if it forms a dominating Set. In this paper we study the problem of partitioning the vertex set of a graph into （global） defensive k-alliances. The （global） defensive k-alliance partition number of a graph Г = （V, E）, ψkgd（F）） ψkd（F）, is defined to be the maximum number of sets in a partition of V such that each set is a （global） defensive k-alliance. We obtain tight bounds on ψkd（F） and ψkgd（F） in terms of several parameters of the graph including the order, size, maximum and minimum degree, the algebraic connectivity and the isoperimetric number. Moreover, we study the close relationships that exist among partitions of F1 × F2 into （global） defensive （kl ＋ k2）-alliances and partitions of Fi into （global） defensive ki-alliances, i ∈ {1, 2}.
