In this report, polypyrrole nanowires have been successfully deposited on interdigitated transducers through template-free electropolymerization. The were 40–90 nm in diameter according to scanning electron microscopy analysis, and some of them bridging the insulating gaps between gold electrodes. An X-ray photoelectron spectroscopy study has conducted determine chemical composition synthesized nanomaterial. developed sensors tested toward five concentrations hydrogen gas at room...
Abstract Due to the difficult access of electrolyte into nanoconfined space nanoporous reduced graphene oxide (rGO) electrodes, achieving optimal electrochemical performance these devices becomes a challenge. In this work, dynamics interfacial‐governed phenomena are investigated during voltage‐controlled activation rGO electrodes that leads an enhanced in terms areal capacitance and impedance. situ/operando characterization techniques used reveal irreversible material changes introduced...
Fast ionic transfer and transport properties continue to be one of the main pressing research concerns regarding energy storage materials (batteries, supercapacitors). Accompanying this search for optimal materials, appropriate characterization tools assess key parameters newly developed are required. In spite its great relevance, fast electrogravimetric methods, i.e., coupling quartz crystal microbalance (QCM) electrochemical impedance spectroscopy (EIS) (ac-electrogravimetry), have not yet...
The interface [BuMeIm][Tf2N]/electrode, where [BuMeIm][Tf2N] stands for the ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, was characterized by electrochemical impedance spectroscopy at different temperatures and electrode materials: platinum (Pt, metallic), glassy carbon (GC, high conductivity), nitride (a-CNx, mean boron-doped diamond (BDD, semiconducting with a quasimetallic character). For Pt, GC, a-CNx, behavior of could be described same equivalent...
Different superhydrophilic polypyrrole nanostructures can be electrosynthezised in the presence of anions weak acid (monohydrogenophosphate) and non-acidic (perchlorate) without need for templates. Actually type formed depends both on concentration at electrode interfacial pH. Depending anion composition pyrrole aqueous solution film electrogenerated under a given applied potential is either very thin membrane (10–20 nm) consisting overoxidized or tridimensional with oriented nanowire array...
To prevent the formation of biofilms on material surfaces, latter must have antibacterial properties. The aim this study is to investigate synthesis and effect a new N-halamine coating based polydopamine (PDA). benefits are multiple, notably green process used prepare it wide variety organic or inorganic materials that can be functionalized. First, PDA by oxidative polymerization dopamine in weak alkaline aqueous solution was studied characterized. Then, these films were exposed NaOCl order...
Abstract Two BODIPY‐C 60 ‐peptide assemblies were synthesized by CuAAC reactions of dyads and a helical peptide functionalized with terminal alkyne group an azide group, respectively. The within these was at its other end disulfide allowing formation self‐assembled monolayers (SAMs) on gold surfaces. Characterizations SAMs, as well those reference molecules (BODIPY‐C ‐alkyl, C BODIPY‐peptide), carried out PM‐IRRAS cyclic voltammetry. SAMs are more densely packed than ‐alkyl BODIPY‐peptide...
A nanocomposite of reduced graphene oxide, polydopamine, and Co 3 O 4 was developed via a one-step hydrothermal process, which showed remarkable electrochemical properties, when used as electrodes in current collector-free μ-supercapacitor device.
This letter deals with an adaptation of the ac-electrogravimetry technique to extract separately dynamic properties H(+) and water in Nafion nanometric thin films (average thickness 400 nm). An original theoretical approach was developed representative parameters from data. The concentration change exchanged species diffusion coefficient protons a film (D = 0.5 × 10(-6) cm(2) s(-1) at 0.3 V vs SCE) were estimated for first time according applied potential. conductivity value calculated...
The new compound (C3N2H5)8[MoV5MoVI7O22(BO4)2(PO4)5(HPO4)3].nH2O is the first molybdenum borophosphate. It contains clusters of twelve molybdenum, eight phosphorus and two boron atoms, [Mo12O22(BO4)2(PO4)5(HPO4)3]8- similar to Wells-Dawson clusters. Five atoms are MoV while others MoVI, five electrons delocalized. According temperature dependence magnetic susceptibility four these paired.
