Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Three types of novel magnetically recoverable core-shell heterogeneous nanoparticle catalysts were prepared by individual grafting of Poly(amidoamine) dendrimer with generation G(0), G(1) and G(2) on Fe3O4-Poly(4-MS-DVB-GMA) core-shell as a common matrix followed by stabilization of AuNPs. The activity of these three catalysts were assessed based on the reduction of Rh-B. The reduction of Rhodamine B reveals that Fe3O4-Poly(4-MS-DVB-GMA)-PAMAM-G(2) is 6 times (kobs = 35.28×10-3 min-1) active than the G(0) dendrimer catalyst and its activity is maintained upto 5th cycle thus enlightening the recyclability and stability.These core-shell magnetic nanocomposites possess many future biological applications. 64 pp. Englisch.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the present study, a stable and convenient form of bead-shaped heterogeneous nanoparticle catalyst viz., PS-PVBC-PPI-(G2)-AuNPs was synthesized using insoluble cross-linked polymer-supported PS-PVBC beads as a matrix and its catalytic activity was examined with Knovenegal condensation reaction. These PS-PVBC-PPI-G2-AuNPs catalyst was able to catalyze the reaction 24 times faster compared to conventional technique. These catalysts maintained its catalytic efficiency even upto five times of recycles.As these catalysts are bead shaped, it can be very well packed into a column reactor and thus the condensation reaction can be conducted in continue mode operation. 52 pp. Englisch.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - With our study we can concluded that, amphiphilic dendrimer can be well suited for the formation of metal nanopartiles viz., Ag, Pd and PtNPs. Based on the performance of APPI-G2 it was inferred that, other types of dendrimers which having similar properties could also be exploited for the same application. As these nanocatalysts selectively reduce the methyl orange, the same can also be extended to chemo selective reduction of azo dyes having different reducible groups under mild conditions.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Se prepararon tres tipos de nuevos catalizadores de nanopartículas heterogéneas con núcleo-cubierta recuperables magnéticamente mediante el injerto individual de dendrímeros de poliamidoamina de generación G(0), G(1) y G(2) sobre un núcleo-cubierta de Fe3O4-poli(4-MS-DVB-GMA) como matriz común, seguido de la estabilización de las nanopartículas de oro (AuNPs). La actividad de estos tres catalizadores se evaluó basándose en la reducción de Rh-B. La reducción de la rodamina B revela que Fe3O4-poli(4-MS-DVB-GMA)-PAMAM-G(2) es seis veces más activo (kobs = 35,28×10-3 min-1) que el catalizador dendrímero G(0) y que su actividad se mantiene hasta el quinto ciclo, lo que pone de manifiesto su reciclabilidad y estabilidad. Estos nanocompuestos magnéticos de núcleo-cubierta poseen muchas aplicaciones biológicas futuras. …
