Effects of polydopamine-passivation on the optical properties of carbon dots and its potential use in vivo
(Royal Society of Chemistry, 2020-07)
Passivation of carbon dots via heteroatom doping has been shown to enhance their optical properties and tune their fluorescence signature. Additionally, the incorporation of polymeric precursors in carbon dot synthesis has ...
Ag/polydopamine-modified Ti/TiO2 nanotube arrays: A platform for enhanced CO2 photoelectroreduction to methanol
(2019-12-01)
TiO2 nanotube (NT) arrays were modified with thin films of polydopamine (PDA) and Ag nanoparticles (NP) and were used as electron storage centers on a photoelectrode surface, in order to drive the reduction of CO2 to ...
Replacing nitrogen by sulfur: From structurally disordered eumelanins to regioregular thiomelanin polymers
(Molecular Diversity Preservation International, 2017-10-17)
The oxidative polymerization of 5,6-dihydroxybenzothiophene (DHBT), the sulfur analog of the key eumelanin building block 5,6-dihydroxyindole (DHI), was investigated to probe the role of nitrogen in eumelanin build-up and ...
Relation between the nature of the surface facets and the reactivity of Cu2O nanostructures anchored on TiO2NT@PDA electrodes in the photoelectrocatalytic conversion of CO2 to methanol
(2020-02-01)
This paper investigates the influence of morphology of Cu2O nanoparticles (cubes, NcCu2O; spheres, NsCu2O; octahedrons, NoCu2O), deposited on TiO2 nanotubes (TiO2NT) coated with PDA, in the photoelectrocatalytic conversion ...
