Effects of Metallic Nanoalloys on Dye Fluorescence
… in a 2.0 mM solution of rose bengal with all nanoalloys, a slight enhancement of fluorescence (1.2 – 1.6 times) was noticed in a 0.13 mM solution of rhodamine B with all four types of NPs, and fluorescence quenching occurred in all the fluorescein-NP solutions regardless of the dye …

Structural and electronic properties of transition metal nanoalloys and magnetic compounds
… questions are closely connected. Bimetallic nanoalloys, e.g., have become increasingly popular as their performance in catalysis is often superior to their pure counterparts. Exemplary for this are gold-platinum (Au-Pt) nanoalloys that have been used as highly potent catalysts in …

Synthesis and Characterization of immobilized Gold Nanoparticles and Binary Gold Nanoalloys on Cationic Spherical Polyelectrolyte Brushes and their Application as a Catalyst
… above were used for the synthesis of binary gold nanoalloys (Chapter 3.4 and 3.6). The binary systems Au-Pt, Au-Ru, Au-Rh and Au-Ir were sucessfully generated. In the next step the nanoparticular structure of these binary systems were completely clarified by different HR-TEM methods and WAXS. It …

Dopant effects on solid-solid transitions in atomic clusters
Multicomponent atomic clusters (i.e. nanoalloys) are currently a subject of intense interest because their properties can be tuned by adjusting the cluster size and composition. Previous work has demonstrated the sensitivity of cluster structure and melting temperature to the presence of a single …

Designing Core/Alloy Nanoparticles by Manipulation of Interfacial Oxidation and Atomic Diffusion
… or phase behavior can emerge. The properties of nanoalloys are highly dependent on their composition and morphology, which are contingent upon the method in which they are synthesized. Finding ways to control, or even design, the composition and morphology of nanoalloys could potentially open the …

Atomistic simulations of semiconductor and metallic nanoparticles
… of silicon, gold and platinum nanoclusters and nanoalloys, in order to provide support for experimental data obtained from collaborating researchers and scientists. Modelled structures of the above nanoparticles were constructed and studied by using a variety of computational tools such as, …

Effective tuning of bimetallic composition of gold-copper nanomolecules and the emergence of plasmon-like feature in optical spectra
Au144-xCux(SR)60 alloy nanomolecules were synthesized and characterized by using ESI-MS to atomic precision. A maximum of 23 copper atoms replace the gold atoms; when the number of copper atoms is higher than eight, a surface plasmon-like peak appears at ∼520 nm. Based on the fundamental, elemental …

Catalysts and electrodes for the electroreduction of carbon dioxide to useful chemicals
… the design, synthesis and application of CuPd nanoalloys with tunable atomic arrangements (atomically ordered, disordered and phase-separated structures) for the electroreduction of CO2 to C2 chemicals. The results of electrochemical measurement as well as structural and compositional …
