Electrooxidation of Formic Acid and Formaldehyde on the Fe3O4@Pt Core-Shell Nanoparticles/Carbon-Ceramic Electrode
In the present work, the electrooxidation of formic acid and formaldehyde; potentially important fuels for future fuel cells, was investigated on the Fe3O4@Pt core-shell nanoparticles/carbon-ceramic electrode (Fe3O4@Pt/CCE). The Fe3O4@Pt nanoparticles were prepared via a simple and fast chemical method and their surface morph...
متن کاملSingle Chain Core-Shell Nanostructure
A combination of static and dynamic laser light scattering has revealed that at temperatures higher than ,33 ±C a linear poly(N-isopropylacrylamide) chain grafted with poly(ethylene oxide) (PNIPAMg-PEO) in water can undergo a “coil-to-globule” transition to form a stable single chain core-shell nanostructure with the collapsed PNIPAM chain backbone as the hydrophobic core and the grafted PEO br...
متن کاملReaction-driven restructuring of Rh-Pd and Pt-Pd core-shell nanoparticles.
Heterogeneous catalysts that contain bimetallic nanoparticles may undergo segregation of the metals, driven by oxidizing and reducing environments. The structure and composition of core-shell Rh(0.5)Pd(0.5) and Pt(0.5)Pd(0.5) nanoparticle catalysts were studied in situ, during oxidizing, reducing, and catalytic reactions involving NO, O2, CO, and H2 by x-ray photoelectron spectroscopy at near-a...
متن کاملColorimetric detection of Escherichia coli O157:H7 using functionalized Au@Pt nanoparticles as peroxidase mimetics.
The presence of Escherichia coli (E. coli) in food and drinking water is a chronic problem worldwide. Protecting food against bacterial contamination and rapid diagnosis of infection require simple and rapid assays for detection of bacterial pathogens, including E. coli O157:H7. Here we report a rapid and novel colorimetric method for detecting E. coli O157:H7. This colorimetric method is based...
متن کاملL-Ascorbic Acid Peroxidase
Euglena gracilis was found to contain a peroxidase that specifically requires L-ascorbic acid as the natural electron donor in the cytosol. The presence of an oxidation-reduction system metabolizing L-ascorbic acid was demonstrated in Euglena cells. Oxidation of L-ascorbic acid by the peroxidase, and the absence of ascorbic acid oxidase activity, suggests that the system functions to remove H20...
