This thesis considers the nucleation and growth, synthesis, and catalytic application of metallic nanoparticles at liquid|liquid interfaces. It comprises five publications, a previously unpublished synthesis of polymer coated palladium nanoparticles, and an introduction to the relevant literature. Three publications are concerned with electrodeposition of metal nanoparticles at liquid|liquid in...

We describe a study, using in situ transmission electron microscopy, of the shape and nucleation kinetics of three-dimensional islands formed during the electrochemical deposition of copper. By operating an electrochemical cell within an electron microscope, we obtain real-time images of the formation of copper islands on a gold electrode while simultaneously recording electrochemical data such...

Microstructure Design In article number 2203229, Shikuan Yang and co-workers propose an avenue to regulate the morphologies of electrodeposits during anodic electrodeposition process by introducing intermediate valence ions (e.g., Pb2+, Mn2+, etc.) into electrolyte solutions. The could react with electrochemically oxidized Ag2+/Ag3+ strong oxidation abilities, affecting growth kinetics Ag7O8NO3...

This communication uncovers missing fundamental elements and an expanded model of gas phase electrodeposition; a relatively new in large parts unexplored process, which combines particle generation, transport zone deposition interacting setup. The process enables selected area charged nanoparticles that are dispersed transported by carrier at atmospheric pressure conditions. Two key parameters ...

Hydrogen is a promising alternative to gasoline due its higher energy density and ability burn cleanly only producing H 2 O as by-product. Electrolytic water splitting an effective technique for generating molecular hydrogen. However, hydrogen be viable source produced from electrolysis, affordable durable electrocatalysts need developed replace platinum. Transition metal dichalcogenides (TMDs)...

The Fe nanowires were prepared by Ac electrodeposition method. The two steps anodized aluminum oxides (alumina) were used as templates for electrodeposition of magnetic nanowires. Sulfuric acid was used to anodize aluminum. The pours diameter and growth rate of alumina were investigated. The FeSO4 electrolyte was used for growth of nanowires. The prepared magnetic nanowires were characterized b...

The initial growth stage of the single-crystalline Sb and Co nanowires with preferential orientation was studied, which were synthesized in porous anodic alumina membranes by the pulsed electrodeposition technique. It was revealed that the initial growth of the nanowires is a three-dimensional nucleation process, and then gradually transforms to two-dimensional growth via progressive nucleation...

cofecu nanowires were deposited by pulsed electrodeposition technique into the porous alumina templates by a two-step mild anodization technique, using the single-bath method. the electrodeposition was performed in a constant electrolyte while cu constant was controlled by electrodeposition current. the electrodeposition current was 3.5, 4.25, 5 and 6 ma. the effect of electrodeposition current...

• “Electrodeposition + Pulling” is proposed for processing and shaping hydrogel. The process synergistically combines electrochemistry with fluid mechanics. Rational control relies on electrodeposition kinetics meniscus evolution. Sharp hydrogel probes of width < 1 µm are obtained local electrochemistry. Electrochemical writing complex 3D structures achieved at tunable resolution. precise high ...

This study examined the characteristics of calcium phosphate coatings formed on untreated and H2O2-treated titanium substrates by electrodeposition in a modified simulated body fluid (SBF). A porous coating comprising of mainly hydroxyapatite (HA) was formed on the H2O2-treated titanium substrate by electrodeposition. This coating was transformed into carbonate and calcium-deficient HA layers w...
