Carbon materials constitute a broad family of solids that encompass high variety physical and chemical properties, including morphology. These have shown to be very useful as catalysts supports and, in this context, also for the heterogenization metal complexes owing catalytic properties. This work is, mainly, summary results obtained several research projects focused on developing heterogenize...

Aqueous biphasic catalysis is a convenient approach to convert organic, partially soluble molecules in water. However, converting more hydrophobic substrates is much more challenging as their solubility in water is extremely low. During the past ten years, substantial progress has been made towards improving the contact between hydrophobic substrates and a hydrophilic transition-metal catalyst....

This paper argues that Information Technology (IT) needs to be demystified, through critical consciousness, for educators to focus on IT as a means to enhance learning. It goes on to define the technical, sociohistorical and political-ideological levels of IT and to identify four theoretical constructs: tutorial, machine-as-human, tool kit and catalyst. Pervading these constructs is the underst...
