A customized MOF-polymer composite for rapid gold extraction from water matrices

Wendy Lee Queen, Daniel Teav Sun, Shuliang Yang, Jun Li, Li Peng, Olga Syzgantseva

With the fast-growing accumulation of electronic waste and rising demand for rare metals, it is compelling to develop technologies that can promotionally recover targeted metals, like gold, from waste, a process referred to as urban mining. Thus, there is ...

Ultimate Limit for Optical Losses in Gold, Revealed by Quantitative Near-Field Microscopy

Sergejs Boroviks

We report thorough measurements of surface plasmon polaritons (SPPs) running along nearly perfect air-gold interfaces formed by atomically flat surfaces of chemically synthesized gold monocrystals. By means of amplitude-and phase-resolved near-field micros ...

Mapping Spatial Distribution of Pores in an Additively Manufactured Gold Alloy Using Neutron Microtomography

Roland Logé, Jamasp Jhabvala, Markus Strobl, Hossein Ghasemi Tabasi, Michaël Meyer

A crucial criterion for the quality of the additively manufactured parts is the porosity content for achieving an acceptable final relative density. In addition, for jewelry applications, visible pores are unacceptable at or in the vicinity of the surface. ...

Influence of Ir Additions and Icosahedral Short Range Order (ISRO) on Nucleation and Growth Kinetics in Au-20.5Wt Pct Cu-4.5Wt PctAg Alloy

Michel Rappaz

Based on detailed EBSD analyses, Kurtuldu et al. (Acta Mater. 70:240-248, 2014) have explained the grain refinement of Au-12.5 wt pctCu-12.5 wt pctAg (yellow gold) by the addition of minute amounts of Ir in terms of icosahedral quasicrystal (iQC)-mediated ...

One-step access to N-enoxyimides by gold-catalysed addition of N-hydroxyimides to terminal alkynes

Nicolai Cramer, Coralie Danielle Annick Duchemin

N-Enoxyimides have become attractive substrates for novel catalytic transformations, yet their tedious multi-step synthesis hampers full exploitation of their synthetic potential. We report a gold(I)-catalyzed protocol to access N-enoxyimides from simple a ...

Electrochemical Co-Deposition of Gold and Carbon Nanocapsules from a Colloidal Suspension

Stefano Mischler

This paper shows the preparation of a gold suspension containing carbon nanocapsules and their co-deposition from the colloidal galvanic bath on a nickel electrode to obtain gold/nanocapsules composite coatings. The incorporation of the nanocapsules was co ...

Tribological response of multilayered gold nickel coating deposited on fine turned surfaces

Stefano Mischler

Gold coating are widely used in industry due to their corrosion resistance, electrical conductivity and low contact resistance. However, friction and wear can limit their functionality and lifetime. This study addresses the degradation of a commercial fine ...

Mixed gold and platinum nanostructured layers for all-solid-state ion sensors

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Danilo Demarchi, Francesca Criscuolo, Lucia Lobello

The great interest in portable and wearable monitoring systems has promoted in recent years a major expansion of all-solid-state Ion-Selective Electrodes (ISEs). Nanostructured Solid-Contacts (SCs) have shown a promising potential in order to eliminate the ...

The Structure of the Cobalt Oxide/Au Catalyst Interface in Electrochemical Water Splitting

Klaus Kern

The catalytic synergy between cobalt oxide and gold leads to strong promotion of the oxygen evolution reaction (OER)one half-reaction of electrochemical water splitting. However, the mechanism behind the enhancement effect is still not understood, in part ...

Nanoparticle on mirror plasmonic nanostructure for molecular cavity optomechanics

Christophe Marcel Georges Galland, Aqeel Ahmed, Nils Kipfer, Tianqi Zhu

The plasmonic response of gold can be utilized to enhance the incident electromagnetic (EM) field by several orders of magnitude. When a gold nanoparticle is placed in close proximity to a gold film, the incident field can excite a deeply confined plasmon, ...
