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...

Tris-(benzyltriazolylmethyl)amine (TBTA) has been immobilized onto a styrenic monomer and subsequently copolymerized with styrene to afford catalytically active and reusable copolymers for the CuAAC reaction.

Results confirm the catalytic potential of imidazole groups anchored on the polymeric backbone of polyvinylimidazole (PVI) in dephosphorylation reactions with diand tri-phosphoesters, promoting impressive enhancements up to 10-fold. We propose the imidazole groups on PVI react by nucleophilic catalysis (neutral specie) with a phosphate triester and bifunctionally by general acid-nucleophilic ca...

Substances that mimic the enzyme action of glutathione transferases (which serve in detoxification) are described. These micellar catalysts enhance the reaction rate between thiols and activated halogenated nitroarenes as well as alpha,beta-unsaturated carbonyls. The nucleophilic aromatic substitution reaction is enhanced by the following surfactants in descending order: poly(dimethyldiallylamm...

A series of novel Si-O-Si crosslinked organic/inorganic hybrid semi-crystalline polymers with shape memory properties was prepared from alkoxysilane-terminated poly(butylene succinate) (PBS) by water-induced silane crosslinking under organic solvent-free and catalyst-free conditions. The hydrolyzation and condensation of alkoxysilane end groups allowed for the generation of silica-like crosslin...

Abstract Exploration of efficient water oxidation catalysts (WOCs) is the primary challenge in conversion renewable energy into fuels. Here we report a molecularly well-defined heterogeneous WOC with Aza-fused, π-conjugated, microporous polymer (Aza-CMP) coordinated single cobalt sites (Aza-CMP-Co). The Aza-CMP-Co exhibited superior activity under alkaline and near-neutral conditions. Moreover,...

The Front Cover shows the interplay between chemisorption of carbon monoxide probe molecules and diffusion through a porous catalyst with stimulus responsive polymeric brushes that can switch transfer process ON- OFF temperature. In their Research Article, M. J. Enes da Silva et al. showed on Polymer-Membrane-Catalyst Assembly (PCMA) system consisting PET membranes well-defined pore structure c...

In the present review, we would like to draw the reader's attention to the polymer-based hybrid materials used in photocatalytic processes for efficient degradation of organic pollutants in water. These inorganic-organic materials exhibit unique physicochemical properties due to the synergistic effect originating from the combination of individual elements, i.e., photosensitive metal oxides and...
