G replacement reactions between solid metal nanoparticles with oxidizing metal precursors represent a versatile strategy for synthesizing hollow metal nanostructures with tailored properties that are difficult (or even impossible) to achieve from their solid counterparts. For example, reactions of silver nanocubes with aqueous solutions of HAuCl4 enable the synthesis of hollow nanoboxes with se...

High enhancement of fluorescence emission, improved fluorophore photostability, and significant reduction of fluorescence lifetimes have been obtained from high aspect ratio (>100) silver (Ag) nanowires. These quantities are found to depend on the surface loading of Ag nanowires on glass slides, where the enhancement of fluorescence emission increases with the density of nanowires. The surface ...

Wearable electronics used in smart clothing for healthcare monitoring or personalized identification is a new and fast-growing research topic. The challenge is that the electronics has to be simultaneously highly stretchable, mechanically robust and water-washable, which is unreachable for traditional electronics or previously reported stretchable electronics. Herein we report the wearable elec...

The use of printed paper electronics in consumer goods is expected to experience a mass development the next future. ink used these devices contains silver nanomaterials that may be released into environment at product end-of-life. We report here first evaluation fate during pilot-scale recycling electronics, made with cellulose nanofibrils-silver nanowire ink. show effluents are mainly free fr...

With the development of chiral materials, remarkable progress has been made in application fields biology, chemistry, and physics past decades. Here we develop a solo-Ag-nanowire (NW)-based, bottom-up construction strategy to fabricate plasmonic film with strong chiroptical activity purple-blue band. Finite-difference time-domain simulations predict that helical structures by Ag NWs certain int...

A multiferroic BiMnO3 nanowire array was prepared using a hydrothermal process and its resistive switching memory behaviors were further investigated. The prominent ferroelectricity can be well controlled by white-light illumination, thus offering an excellent light-controlled resistive switching memory device using a Ag/BiMnO3/Ti structure at room temperature.

The excitation spectra of linear atomic chains of silver and gold with various sizes have been calculated using time-dependent density functional theory. Silver chains show longitudinal and transverse peaks as well as a low-intensity d-band. The longitudinal peak, corresponding to the HOMO-LUMO transition (along the main axis of the chain), shifts linearly to the red as the length of the system...
