Incorporation of a gold nano-scaffold into silver electrode greatly improves the performance secondary Zn–Ag aqueous batteries.
This study explores dynamics of silver-based memristors under steadybias, revealing current fluctuations with power-law distribution. is analyzed using Marcus-Tang theory. has implications for encryption and computing.
Abstract Au–Ag nanostructures comprising of ∼1 nm Ag nanoparticles embedded into an Au matrix show several unconventional optical, electric and magnetic properties. Here, we review progress made towards the preparation these materials as well analysis their structure. Further, electrical transitions in are discussed. Finally, properties revealed from optical electron microscopic probes.
A new crystal polymorph of CTAB–I with smaller unit cell size and reduced cetyl chain mobility is observed. In situ embedding plasmonic metal nanoparticles into this realized leading to materials strong plasmon–plasmon coupling.
Bimetallic nanostructures can exhibit significant broadening of Mie resonances compared to monometallic nanoparticles. Here, we study these materials using Electron Energy Loss Spectroscopy at a single particle level. This technique is immensely effective probe direct structure-property correlation We are thus able confirm the effect analyzed in context emergence new dielectric constant that originates from metallic interfaces. employ Coronado-Schatz corrections usual constants constituent...
Quantum photonic devices require robust sources of single photons to perform basic computational and communication protocols. Thus, developing scalable, integrable, efficient quantum light has become crucial for the realization devices. Single dots are promising due their tunable emission wavelength. Here, we show emergence quantum-emitter-like antibunched behavior when multiple located in vicinity plasmonic particles. To evaluate robustness this phenomenon, consider both monometallic...
Metal nanoparticles are excellent absorbers and scatterers of light due to localized surface plasmon resonance (LSPR) at the metal–dielectric interface. LSPRs have been extensively studied shown act as sensitive dielectric-refractive index sensors. However, all refractive index-based sensors, by their design, encounter difficulties in distinguishing between dielectrics with similar indices. We developed a material made metal embedded into cysteine-based coordination polymer that shows strong...
Nanostructuring can greatly improve the electrode stability of rechargeable battery systems, such as Zn-Ag. In this report, we investigate physical mechanisms by which nanostructuring alters structural properties nanomaterials and thereby influences electrodes. We specifically consider effects Au-based nanoscaffolds on Ag. Through density functional theory calculations, propose that charge transfer at Au-Ag interface facilitate formation Ag

We describe the unusual dielectric properties of Au-Ag nanostructures at a single particle level using electron energy loss spectroscopy. It has been shown previously that these deviate from their usual metallic characteristics Ag and Au. In particular certain variants materials appear to undergo transition an immeasurably low resistive state as well strong diamagnetic is not usually associated with Au themselves. More significantly exhibit absence Mie like resonances Ag. Instead, negligible...
1D and 2D superconductors show finite resistance below transition temperature due to the occurrence of phase slip centers in current carrying path. Au-Ag nanostructured films have been posited as candidate materials for supporting superconductivity ambient that furthermore are prone behavior. In this paper we study employ these characterize disorder well improve upon film quality. As prepared were characterized through techniques such XRD, SEM, TEM UV-Vis optical spectroscopy....
