The electrooxidation of glucose on gold (Au) and platinum (Pt) nanoparticles (NPs) is investigated in alkaline medium by cyclic voltammetry after chronoamperometry at different potentials (+0.100 V, +0.200 +0.400 V vs the reversible hydrogen electrode, RHE), situ Fourier transform infrared spectroscopy, differential electrochemical mass spectrometry measurements. We show that can adsorb both me...

In this work, Pt, Fe and Co nanoparticles were prepared by chemical reduction of the metal salts in chitosan as the support. NaBH4 was used as the reducing agent Pt-Fe, Pt-Co and Pt-Fe-Co-chitosan nanocomposites were synthesized and characterized by UV–Vis spectra and Transmission electron microscopy images. GC/Pt-chitosan, GC/Pt-Co-chitosan, GC/Pt-Fe-chitosan and GC/Pt-Co-Fe-chitosan electrode...

The Au–Bi binary system electrodeposited on the surface of a glassy carbon electrode exhibits catalytic activity during electrooxidation phenylephrine, paracetamol, and caffeine that enhances peak currents decreases overvoltage in oxidation organic compounds. potential difference between peaks modified is 400 mV for phenylephrine paracetamol 300 caffeine, respectively. possibility simultaneous ...

in the present study, ptruce/mwnts nanocatalysts synthesized via polyol process technique are applied as anode electro-catalyst in methanol electro-oxidation reaction (mor). to characterize the nanocatalysts, tem, xrd, eds and xps are investigated. cyclic voltammetry and choronoamperometry are used to evaluate the electro-catalytic activity and stability of the catalysts in methanol electro-oxi...

The DNA-templated bioorthogonal synthesis of macrocyclic gene modulators is illustrated in the cover picture accompanying Research Article (e202215245) by Jyotirmayee Dash and co-workers. DNA secondary structures present telomere oncogene promoter proximally orient bifunctional alkyne azide fragments, enabling bond formation copper-free azide–alkyne cycloaddition live cells. high-affinity bindi...
