Enzyme Immobilization on magnetic nanoparticles for enhancing biocatalysis

Liu C., Institute of Process Engineering, Chinese Academy of Sciences, CN

Magnetic nanoparticles have a wide range of applications in catalysis, separation, magnetic resonance imaging and drug delivery. This talk focuses on the synthesis, functionalization and application of magnetic nanoparticles for improving biocatalysis. Great progress in [...]

Nanoporous thin film fabrication via magnetron sputtering and O2 plasma ashing process

Han S.H., Jang S.W., Hwang S., Hwang S.H., Hwang S., Hwang S.H., Korea Institute of Science and Technology, KR

We report a new method of fabricating nanoporous catalytic thin films. In the first step, metal–carbon thin films were prepared by reactive magnetron sputtering, using various metallic targets (Au, Ag, Pt, Cu, Ni, Ti) as [...]

Azide-alkyne cycloaddition by recyclable heterogeneous Cu catalysts on reverse phase silica gel

Jang Y., Kim H., Lim M., Rhee H., Hanyang University, KR

Previously, we developed heterogeneous Pd catalysts immobilized onto functionalized reverse phase silica gel. These catalysts were applied to Suzuki cross coupling reactions and the hydrogenation reactions in water with good results. In this study, Cu [...]

Pd nanoparticles immobilized onto polymer-inorganic hybrid support: Synthesis, characterization and catalytic activity on Suzuki-Miyaura coupling reactions in water

Lim M., Kim H., Jang Y., Rhee H., Hanyang University, KR

The development of heterogeneous metal catalysts supported on a solid support has attracted attention. This catalyst system has the advantages of ease of catalyst separation and reusability, and has higher reactivity due to the larger [...]

Partially Poisoned Pd Nanoparticles for Selective Hydrogenation and/or Isomerization of Olefins

Shon Y-S, California State University Long Beach, US

Selective hydrogenation and/or isomerization of olefins are important processes in both chemical and pharmaceutical industries. Our group previously reported that the thiosulfate protocol using sodium S-alkylthiosulfates instead of alkanethiols could generate catalytically active Pd nanoparticles [...]

Physical and chemical transformations of silver nanomaterials in textiles after use

Gorka D.E., Gorham J.M., National Institute of Standards and Technology, US

Nanomaterials have been increasingly used in consumer products and silver nanomaterials (AgNMs) especially have been used for their antibacterial properties. Increased use of AgNMs in consumer products will result in their increased disposal and entrance [...]

Cataphotolysis of Propanil in water using nanotechnology

Yu Z., Wu V., Li Z., California State Polytechnic University, Pomona, US

Irrigation of farmland consumed approximately 80% of total water usage in California. The costs associated with groundwater monitoring and cleansing have cost the state more than $33 millions of dollars. This research project has significant [...]
