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 ...

Electron backscatter diffraction study of variant selection during ordering phase transformation in L1(0)-type red gold alloy

Roland Logé, Cyril Cayron, Margaux Nathalie Dominique Larcher

A shape-memory effect is known to appear in red gold alloys with compositions close to Au-Cu. The aim of this paper is to study by electron backscatter diffraction (EBSD) the variant selection in the A1 -> L1(0) transformation occurring under stress, in be ...

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 ...

Photorealistic modelling of metals from first principles

Nicola Marzari, Gian-Marco Rignanese, Gianluca Prandini

The colours of metals have attracted the attention of humanity since ancient times, and coloured metals, in particular gold compounds, have been employed for tools and objects symbolizing the aesthetics of power. In this work, we develop a comprehensive fr ...

Probing the interaction of nanoparticles with small molecules in real time via quartz crystal microbalance monitoring

Stefan Guldin, Nikolaos Nianias

Despite extensive advances in the field of molecular recognition, the real-time monitoring of small molecule binding to nanoparticles (NP) remains a challenge. To this end, we report on a versatile approach, based on quartz crystal microbalance with dissip ...

Synthesis and Characterization of Amphiphilic Gold Nanoparticles

Francesco Stellacci, Paulo Henrique Jacob Silva, Matteo Gasbarri, Zhi Luo, Zekiye Pelin Güven, Urszula Beata Cendrowska, Samuel Thomas Jones

Gold nanoparticles covered with a mixture of 1-octanethiol (OT) and 11-mercapto-1-undecane sulfonic acid (MUS) have been extensively studied because of their interactions with cell membranes, lipid bilayers, and viruses. The hydrophilic ligands make these ...

Heat-transfer at the interface between a metal and a non-metal: influence of ultra-thin interlayers, interface chemistry and atomic order

Maïté Blank

The Thermal Boundary Conductance (TBC) at the interface between metals and dielectrics is of key importance for heat transport in structures heterogeneous on a scale from 100 µm downwards. In this thesis the TBC of a large number of metal/dielectric couple ...

Influence of Minor Additions on Icosahedral Short-Range Order (ISRO) and Its Consequences on Nucleation and Solidification Growth Kinetics in fcc Alloys

Michel Rappaz

The present contribution reviews the recent progress related to the influence of icosahedral short-range order (ISRO) and icosahedral quasicrystal (iQC) formation on the solidification of fcc alloys through minor solute element additions. From intensive cr ...

Nanoparticle on mirror plasmonic nanostructure for molecular cavity optomechanics

Christophe Marcel Georges Galland, Santiago Tarrago Velez, Aqeel Ahmed

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, ...
