In this paper, the flame-retardant synergistic effect between rare earth oxide and conventional flame retardants (aluminum hydroxide and iron trioxide) has been studied using vertical combustion test. The results show that good flame-retardant synergistic effect exists between them. The composites combining 100 grams of aluminum hydroxide, 40 grams of iron trioxide and 0.8 grams of rare earth oxide can reach FV-0 in vertical combustion test. The thermal stability influence of rare earth oxide to silicone rubber has also been studied by means of thermogravimetric analysis. It has been found that rare earth oxide can function as thermal stabilizer in silicone rubber.

In the present work, the pyrolysis of polypropylene and polyethylene was evaluated with and without the addition of niobium oxide as catalyst by means of thermogravimetric analysis and experiments in a glass reactor. The results revealed that niobium oxide performed well in the pyrolysis of both polypropylene and polyethylene separately. For the mixture of polypropylene with polyethylene, the catalyst reduced the pyrolysis time.

This chapter examines the politics of the currency in West Africa from the beginning of the twentieth century. A public series of debates over the nature of the currency occurred in West Africa during both the colonial and independence periods. Since 1983, West African countries have been pioneers in Africa in developing new strategies to combat overvaluation of the currency and reduce the control of government over the currency supply. The chapter charts the evolution of West African currencies as boundaries and explores their relationship to state consolidation. It shows that leaders in African capitals managed to make the units they ruled increasingly distinct from the international and regional economies, but the greater salience of the currency did not end up promoting state consolidation. Rather, winning the ability to determine the value of the currency led to a series of disastrous decisions that severely weakened the states themselves.
