The iron-based Fischer–Tropsch catalysts were studied using Mössbauer spectroscopy, BET surface area, XRD and SEM characterization methods. Adding SiO2 to the catalyst during precipitation or immediately after precipitation (i.e., precipitated SiO2) results in the formation of

Femtosecond laser control of chemical reactions is made possible through the use of pulse-shaping techniques coupled to a learning algorithm feedback loop – teaching the laser pulse to control the chemical reaction. This can result in controllable relative fragmentation ratios for unimolecular dissociation reactions – therefore selectively breaking bonds in a molecule. More interestingly, the same techniques can be used to provide control over chemical reactions involving two or more reactant molecules, where these come together, react and produce new reaction products. The reaction product ratios can be controlled in this way, providing a new form of selectivity in addition to the usual variation of temperature, pressure and catalysts in chemical reactions. In this work, low-pressure gas-phase laser-induced chemical reactions were ...

South Africa hopes that a focus on photonics technologies will help drive the country's socioeconomic development. Figure 1 philemon mjwara (left), the director general of the dst, during a visit to the research labs of the nlC. thulani dlamini (right), the director of the nlC, is showing him a high-power nd:YlF laser developed at the centre. the dst strongly supports photonics research in south Africa.
