Spindle-shaped nanoscale yolk/shell magnetic stirring bars for heterogeneous catalysis in macro- and microscopic systems.
A new type of spindle-shaped nanoscale yolk/shell magnetic stirring bar containing noble metal nanoparticles was prepared. The as-synthesized Pd-Fe@meso-SiO2 not only showed impressive activity and stability as a heterogeneous catalyst in a macroscopic flask system, but also acted as an efficient nanoscale magnetic stir bar in a microscopic droplet system.
متن کاملMagnetic Properties of Magnetotactic Bacteria
This paper reports on the magnetic properties of magnetosomes in the freshwater magnetotactic bacterium Aquaspirillum nlllgnetOlaClicwn. The magnetosomes are well crystallized particles of magnetite with dimensions of 40 to 50 nm, which are arranged within cells in a single linear chain and are within the single-magnetic-domain (SO) size range for. magnetite. A variety of magnetic properties ha...
متن کاملA pH-switched Pickering emulsion catalytic system: high reaction efficiency and facile catalyst recycling.
A smart Pickering emulsion catalytic system is constructed, which not only exhibits fivefold reaction rate enhancement effects in comparison to the conventional biphasic system but also can be facilely demulsified by tuning pH, allowing for in situ recycling nanocatalysts.
متن کاملMaterial : Aging mechanism in model Pickering emulsion
The chemicals used for the NPs synthesis are TetraEthylOrthoSilicate (TEOS), l-Arginine, chloride acid 0.1M and ethanol. They were supplied by Aldrich and used as received. High-purity deionized water (18.2 M.cm) was produced using Millipore Milli-Q Gradient system. The synthesis follows the same protocol as in our previous work [1]. It is performed in a 2000 ml reactor thermostated with hot wa...
متن کاملMolecular imprinting of protein in Pickering emulsion.
A new strategy of molecular imprinting to prepare spherical hydrogels via water-in-oil Pickering emulsion polymerization was developed. The imprinted hydrogels exhibited fast adsorption kinetics and significant selectivity for the target protein.
