Modeling of self-gydrolysis of concentrated sodium borohydride solution

In spite of the US DOE recommendation of no-go for sodium borohydride for on-board vehicular hydrogen storage, a great deal of interest remains particularly with view to portable applications. In this work we report on experimental and modeling studies of the kinetics of self-hydrolysis of concentrated NaBH4 solutions (10 – 20 wt %) for temperatures varying between 25 – 80 0C, based on 11B NMR study. The models...

On the number of invariant factors of matrix products

We prove an inequality relating the number of nontrivial invariant factors of n × n matrices A and B, with those of AB, and get some results on the cases of equality. In particular, we characterize the similarity classes, and , with all eigenvalues in the base field, such that AB is nilpotent for some and . ; http://www.sciencedirect.com/science/article/B6V0R-4F29J0H-6/1/e03b2d17dbee9bd012faadaa2f58683d

On the number of invariant polynomials of the product of matrices with prescrib...

We study the possibilities for the number of nontrivial invariant polynomials of the product of two nonsingular matrices, with prescribed similarity classes, over an algebraically closed field. ; http://www.sciencedirect.com/science/article/B6V0R-3TKS76P-20/1/bc3af1e451ec3fe18a7b16fbd3b418ef
