Gold

goldZum Golde drängt, am Golde hängt doch alles.
For gold contend, On gold depend All things.

J. W. Goethe, Faust I

The element gold has many personalities, of which the image of a noble but soft, yellow metal would first across one's mind. The recently discovered nanoparticles and nanowires containing gold are a natural extension of this aspect, as are the uses of gold in electronics and decoration. Thought to be noble, gold actually has a rich chemistry. Fascinating in its complexity for academic chemists, this chemistry has potential applications in materials science, medicine and, recently, in both heterogeneous and homogeneous catalysis. Some fresh promises are related to the optical properties of certain gold compounds or to the possibility of forming new nanostructures based on gold. The unique properties of gold are strongly influenced by relativistic effects.

Graphene Optical Switch Based on Charge Transfer Plasmons

Graphene Optical Switch Based on Charge Transfer Plasmons

An ultra-large modulation depth, efficient, fast, electrically tunable, and compact telecommunication optoelectronic switch is proposed for optical telecommunication applications. Tuning the photoconductivity of graphene sublayer allows for the excitation of functional charge transfer plasmon (CTP) peak in the near-infrared regime. The gate-tunable CTP extreme is appears and vanishes when the corresponding photoconductivity of graphene junction increases and decreases, respectively.

Controllable Synthesis and Structural Analysis of Nanohybrids with Gold Multipod Nanoparticle Cores and ZIF‐67 Shells (GMN@ ZIF‐67)

Gold multipod nanoparticle cores–zeolitic imidazolate framework shells (GMN@ZIF-67) nanohybrids are successfully synthesized and fully characterized. The size of the GMN@ZIF-67 nanohybrids can be adjusted by either varying the molar ratio of ZIF-67 precursors or the quantity of GMNs used.

3D Nanoporous Gold with Very Low Parting Limit Derived from Au‐Based Metallic Glass and Enhanced Methanol Electro‐oxidation Catalytic Performance Induced by Metal Migration

3D Nanoporous gold (NPG) was fabricated by facile chemical-dealloying method, through which a novel porous ′cone shaped protrusion′ morphology was formed on the top of a surface. NPG@Pd catalyst was fabricated using this specific topology as a substrate to load Pd thin film and enhance methanol electro-oxidation performance induced by metal migration effect between NPG substrate and Pd thin film.

Selective C−H Bond Cleavage in Methane by Small Gold Clusters

Selective C−H Bond Cleavage in Methane by Small Gold Clusters

Selection by gold: Vibrational spectroscopy in conjunction with first-principle calculations demonstrate that small gold clusters can mediate the selective dissociation of one of the four C−H bonds of methane, and thus represents the first step towards its conversion into higher quality chemicals. The distinct selectivity of these gold clusters originates from their finely balanced electronic structure. Au yellow, C gray, H white.

Fabrication of Calcium Phosphate‐Based Nanocomposites Incorporating DNA Origami, Gold Nanorods, and Anticancer Drugs for Biomedical Applications

A biocompatible photothermal and pH dual responsive nano-in-nanocomposite is developed to both protect DNA origami from degradation and facilitate loading of therapeutics. The DNA origami, gold nanorods, and anticancer drugs are co-incorporated into calcium phosphate nanoparticles coated with a thin layer of phospholipid. The nanocomposites synergistically induce cancer cell apoptosis and reduce the multidrug resistance for potential clinical and biomedical applications.

Alkynyl Thioethers in Gold‐Catalyzed Annulations to form Oxazoles

Taking a different path: The first gold-catalyzed annulations with alkynyl thioethers are reported. This transformation provides ready and convergent access into densely-functionalized 1,3-oxazole motifs. The sulfur substituent is integral to accessing the desired reactivity and provides a useful synthetic handle for later elaboration. In contrast with recent reports, the reaction does not follow a ketenethionium pathway.

A Gold‐Nanoparticle‐Based SERS Reporter that Rolls on DNA Origami Templates

A gold nanoparticle (AuNP)-based plasmonic nano-reporter is demonstrated, in which a AuNP performs as a walker to stepwise roll directionally and progressively on DNA origami. Using another AuNP as a stator, the rolling of the AuNP reporter could generate the inter-particle distance variation, which would be monitored by surface-enhanced Raman scattering (SERS).

Thermodynamic parameters of the temperature-induced phase transition of heterotelechelic poly(N-isopropylacrylamide) brushes grafted onto gold nanorods are studied by 1H high-resolution magic-angle sample spinning NMR spectroscopy and compared to free polymer in aqueous solution. Transition temperature, entropy, and width of transition demonstrate remarkable differences depending on the molecular weight and polarity of the free, terminal end groups.
