Gold Provenance in placers from Pureo area, southern Chile coastal cordillera, and their relationship with paleozoic metamorphic rocks
(MDPI, 2022)
Southern Chile placer gold deposits have been known and exploited since Spanish colonial times. Despite this, precise knowledge about their origin is scarce. This work aims to identify possible primary sources of the gold ...
A novel environmentally friendly method in solid phase for in situ synthesis of chitosan-gold bionanocomposites with catalytic applications
(Elsevier Ltd, 2019)
A novel method to obtain catalytic bio-nanocomposites based on chitosan containing different amounts of gold nanoparticles generated in situ is reported. The formation of gold nanoparticles takes place in solid phase ...
Designing the SART process – A review
(Elsevier B.V., 2018)
© 2018 Elsevier B.V. Almost twenty years ago, the first paper about the SART process was published, and eleven years ago the first SART plant was commissioned and operated at Telfer mine, in Australia. Up to this moment, ...
Designing the SART process – A review
(Elsevier, 2018)
Almost twenty years ago, the first paper about the SART process was published, and eleven years ago the first
SART plant was commissioned and operated at Telfer mine, in Australia. Up to this moment, seven SART processes
have ...
The effects of gold nanoparticles functionalized with ß-amyloid specific peptides on an in vitro model of blood–brain barrier
(Elsevier Inc., 2017)
© 2017 Elsevier Inc. We studied the effect of gold nanoparticle (AuNP) size, surface charge, concentration and morphology on the integrity of the blood–brain barrier (BBB) in a well-established in vitro model set-up. We ...
The effects of gold nanoparticles functionalized with beta-amyloid specific peptides on an in vitro model of blood–brain barrier
(Elsevier, 2017)
We studied the effect of gold nanoparticle (AuNP) size, surface charge, concentration and morphology on the integrity of the blood–brain
barrier (BBB) in a well-established in vitro model set-up. We focused on the effect ...
Exploration of the Interaction Strength at the Interface of Anionic Chalcogen Anchors and Gold (111)-Based Nanomaterials
(MDPI, 2020)
Nowadays, the use of sulfur-based ligands to modify gold-based materials has become a common trend. Here, we present a theoretical exploration of the modulation of the chalcogenides-gold interaction strength, using sulfur, ...
The optimal windows for seismically-enhanced gold precipitation in the epithermal environment
(Elsevier Science BV., 2016)
Epithermal gold (Au) deposits result from the combination of a sustained flux of metal-rich fluids and an efficient precipitation mechanism. Earthquakes may trigger gold precipitation by rapid loss of fluid pressure but ...
Stable Conjugates of Peptides with Gold Nanorods for Biomedical Applications with Reduced Effects on Cell Viability
(American Chemical Society, 2013)
Gold nanorods used in therapy and diagnosis
must be nontoxic and stable in biological media and should be
specific for the target. The complete combination of these
three factors has hindered the use of gold nanorods ...
Amino β-cyclodextrins immobilized on gold surfaces: Effect of substituents on host-guest interactions
(Elsevier Ltd, 2018)
In the present paper we describe a simple method to immobilize amino cyclodextrins (CDs) and methylated-amino cyclodextrins on gold surfaces. We also report on the effect that the presence of methyl groups in the broader ...
