Two other fuels, FeSi₇ and CaSi₂, gave similar thermal analysis curves when used instead of silicon. There were considerable differences in the burning rates for binary mixtures of these fuels compared to silicon. Ternary systems with two fuels or two oxidants showed that only limited interaction occurs during thermal analysis. The use of a second fuel or oxidant did, however, modify the burning behaviour considerably. Other techniques used in this study to probe the details of the reaction processes included bomb calorimetry, measurement of thermal conductivities, infrared spectroscopy, X-ray diffraction and scanning electron micoscropy.]]> Wed 12 May 2021 17:32:43 SAST ]]> The chemistry of Algoa Bay ascidians https://vital.seals.ac.za/vital/access/manager/Repository/vital:4560 Thu 13 May 2021 08:53:23 SAST ]]>
