This chapter deals with acid–base bifunctional heterogeneous catalyst surfaces with organofunctional groups. One of the most important issues for bifunctional heterogeneous catalysis is the coexistence of incompatible catalytic species, such as acid and base, nearby on a same solid particle surface. In nucleophilic reactions, acid–base bifunctional catalysts enable the activation of both nucleo...

this work undertakes the study of the detoxification reactions of o, s-dimethyl phosphoramidithioate (methamidophos) as an organophophorus insecticide on the 14.7 wt% magnetite (fe3o4) nanoparticles/ag-nay faujasite molecular sieve zeolite (fmsz) composite. the influence of solvent (methanol, acetonitrile and n-hexane) on the detoxification potential of composite was investigated. for this surv...

Real-time reverse transcription polymerase chain reaction (RT-PCR) is a commonly used technique to analyze gene expression. There has been little research conducted to test if SuperScript III quantitative one-step (reverse transcription carried out in the same tube as PCR) and two-step (reverse transcription carried out in a separate reaction) RT-PCR systems provide similar real-time results. I...

One of the dream reactions in polymer chemistry is the bottom-up, self-assembled synthesis of polymer fabrics, with interwoven, one-dimensional fibres of monomolecular thickness forming planar pieces of textiles. We have made a major step towards realizing this goal by assembling sophisticated, quadritopic linkers into surface-mounted metal-organic frameworks. By sandwiching these quadritopic l...
