Quantitative CT analysis in patients with pulmonary emphysema: is lung function influenced by concomitant unspecific pulmonary fibrosis? [PDF]

, 2019
Purpose: Quantitative analysis of CT scans has proven to be a reproducible technique, which might help to understand the pathophysiology of chronic obstructive pulmonary disease (COPD) and combined pulmonary fibrosis and emphysema.

Synthesis and reactivity of gold(III) complexes containing cycloaurated iminophosphorane ligands [PDF]

, 2009
Transmetallation reactions of ortho-mercurated iminophosphoranes (2-ClHgC₆H₄)Ph₂P NR with [AuCl₄]⁻ gives new cycloaurated iminophosphorane complexes of gold(III) (2-Cl₂AuC₆H₄)Ph₂P NR [R = (R,S)- or (S)-CHMePh, p-C₆H₄F, tBu], characterised by NMR and IR ...

Dihaloperhaloaryl(triphenylarsine)gold(III) Complexes

Journal of Organometallic Chemistry, 1975
When C6CISAuAsPh3 reacts with halogens, oxidation of the gold(I) complex and formation of X2Au(C6C15)AsPh3 (X = Cl, Br, I) take place. However, when C6F5AuAsPh3 reacts with halogens, oxidation is only observed in the case of Cl2 whilst I2 (totally) and Br2 (partially) split the Au-C bond.

Perhalophenyl–Phosphide: A Couple Needed to Stabilize Phosphide–Gold Complexes

Inorganics
The synthesis of gold(III) and gold(I)–gold(III) complexes with phosphide bridges is still a matter that requires solutions for their marked instability, in spite of the affinity of this metal in both oxidation states for phosphorous donor ligands.

Advancement of Fluorescent and Structural Properties of Bovine Serum Albumin-Gold Bioconjugates in Normal and Heavy Water with pH Conditioning and Ageing

Nanomaterials, 2022
The red-emitting fluorescent properties of bovine serum albumin (BSA)–gold conjugates are commonly attributed to gold nanoclusters formed by metallic and ionized gold atoms, stabilized by the protein.

Dispersion, solvent and metal effects in the binding of gold cations to alkynyl ligands: implications for Au(i) catalysis. [PDF]

, 2015
The coordination modes of the [Au(PPh3)](+) cation to metal alkynyl complexes have been investigated. On addition to ruthenium, a vinylidene complex, [Ru(η(5)-C5H5)(PPh3)2([double bond, length as m-dash]C[double bond, length as m-dash]CPh{AuPPh3 ...

A dual catalytic strategy for carbon-phosphorus cross-coupling via gold and photoredox catalysis. [PDF]

, 2014
A new method for the P-arylation of aryldiazonium salts with H-phosphonates via dual gold and photoredox catalysis is described. The reaction proceeds smoothly at room temperature in the absence of base and/or additives, and offers an efficient approach ...

A New Impregnated Adsorbent for Noble Metal Ion Sorption

Molecules, 2023
Noble metals (NM) such as gold, platinum, palladium, and rhodium are widely applied in the electronics and automotive industries. Thus, the search for cheap and selective sorbents for noble metals is economically justified.
