Toxic Pigment in a Capacocha Burial: Instrumental Identification of Cinnabar in Inca Human Remains from Iquique, Chile
(Blackwell Publishing Ltd, 2018)
© 2018 University of Oxford We report on the analysis of a red pigment found in a lavish Inca burial from Cerro Esmeralda, Chile, associated with the human sacrifice of two young girls. The outcome shows that the red pigment ...
Adsorption of oligopeptides on silver nanoparticles: surface-enhanced Raman scattering and theoretical studies
(JOHN WILEY & SONS LTD, 2010-01-18)
The MRKDV peptide structurally associated with an immunomodulatory protein, as well as model peptides ADEDRDA and
LGRGISL with common amino acid residues were studied using surface enhanced Raman scattering (SERS) supported ...
Vibrational interpretation of the structure of Co(II), VO2+ and Pb(II) naphthalocyanine complexes
(1997)
The FT-IR and Raman spectra for the solid naphthalocyanine (H2Nc) and their Co(II), VO2+ and Pb(II) complexes were registered, and a band assignment was proposed. On this basis, the structure of the complexes was inferred: ...
Interaction of the CLPFFD peptide with gold nanospheres. A Raman, surface enhanced Raman scattering and theoretical study
(Elsevier, 2015)
In a previous work we demonstrated that toxic aggregates of the protein b-amyloid (ATAb) involved in
the Alzheimer’s disease (AD) can be destabilized upon electromagnetic irradiation of the peptide Cys-
Leu-Pro-Phe-Phe-Asp ...
Characterization of sodium alginate and its block fractions by surface-enhanced Raman spectroscopy
(JOHN WILEY & SONS LTD, 2009-10-23)
The surface-enhanced Raman scattering (SERS) of sodium alginates and their hetero- and homopolymeric fractions obtained
from four seaweeds of the Chilean coast was studied. Alginic acid is a copolymer of β-D-mannuronic ...
Identification of coexisting indigo species in an ancient green thread using direct plasmon-enhanced Raman spectroscopy
(Sociedad Chilena de Quimica, 2020)
Detection of liquid H2O in vapor bubbles in reheated melt inclusions: Implications for magmatic fluid composition and volatile budgets of magmas?
(Mineralogical Society of America, 2016)
Fluids exsolved from mafic melts are thought to be dominantly CO2-H2O S fluids. Curiously, although CO2 vapor occurs in bubbles of mafic melt inclusions (MI) at room temperature (7), the expected accompanying vapor and ...
Raman identification of pigments in wall paintings of the colonial period from bolivian churches in the ruta de La Plata
(Mimesis Edizioni, 2017)
Micro-Raman spectroscopy was used to analyze and identify pigments and determine the palette of color in wall paintings from four churches of the Colonial Period, in the Bolivian highlands. The ancient churches Santiago ...
Fabrication of ZnSe nanoparticles: structural, optical and raman studies
(Elsevier, 2017)
In this work, a simple, effective, reproducible and green fabrication process for the production of high-quality, pureZnSe nanoparticles at low temperature is presented. The structural and optical properties of these nano ...
