Alteration of Asian lacquer: in-depth insight using a physico-chemical multiscale approach

Abstract: Oriental lacquer has been used in Asian countries for thousands of years as a durable and aesthetic coating material for its adhesive, consolidating, protective and decorative properties. Although these objects are made from an unusual material in Occident, Western museum collections host many lacquerwares...

Characterisation of the steel concrete interface submitted to chloride-induced-corrosion

Abstract: This paper deals with the characterisation by means of electrochemical, gravimetric and analytical methods of chloride‐induced‐corrosion behaviour of steel coupons embedded in chloride‐containing‐cement pastes. Corrosion rates were estimated from electrochemical measurements as well as gravimetric ones...

Moganite detection in silica rocks using Raman and infrared spectroscopy

Abstract: The quantitative determination of moganite in flint and chert plays an important role in the characterisation of these silica rocks and in the study of their genesis and evolution. Both Raman and infrared (IR) spectroscopy promise to be rapid and costeffective tools for such studies...

Heat treatment in the South African Middle Stone Age: temperature induced transformations of silcrete and their technological implications

Abstract: It was recently found that silcrete raw material was heat-treated during the South African Middle Stone Age (MSA) for altering its flaking properties. This finding led to hypotheses about the implications for the MSA hunter-gatherers such as the cost of thermal treatment in terms of investment and firewood...

Small angle neutron scattering on an absolute intensity scale and the internal surface of diatom frustules from three species of differing morphologies

Abstract: The internal nanostructure of the diatoms Cyclotella meneghiniana, Seminavis robusta and Achnanthes subsessilis was investigated using small angle neutron scattering (SANS) to examine thin biosilica samples, consisting of isotropic (powder) from their isolated cell walls. The interpretation of SANS data was assisted by several other measurements...

Heterogeneity in iron doped titania flower-like nano aggregates - detection of brookite and anatase/rutile size-strain modelling

Abstract: Detailed investigations of Raman spectra and X-ray powder diffraction (XRPD) patterns of rutile-rich and anatase/brookite-poor flower-like nanocrystalline aggregates of Fe-doped TiO2 shed new light with regard to its microstructure and heterogeneity. The brookite phase has been detected from the Raman spectra, and the presence of different phases in pure and doped samples is discussed...

Testing the chemical/structural stability of proton conducting perovskite ceramic membranes by in situ/ex situ autoclave Raman microscopy

Abstract: Ceramics, which exhibit high proton conductivity at moderate temperatures, are studied as electrolyte membranes or electrode components of fuel cells, electrolysers or CO2 converters. In severe operating conditions (high gas pressure/high temperature), the chemical activity towards potentially reactive atmospheres (water, CO2, etc.) is enhanced...

Mobile Raman spectroscopy analysis of ancient enamelled glass masterpieces

Abstract: Richly decorated enamelled glass objects and fragments of different provenance and epoch have been analysed using mobile and fixed Raman instruments: some fragments of the outstanding Begram treasure (Musée des arts asiatiques – Guimet, Paris) dated to the 1st century AD, mosque lamps and bottles of Syrian/Egyptian provenance dated to the 13th/14th century (collections of Musée du Louvre and of Musée des arts décoratifs, Paris)...

The destructive/non-destructive identification of enamelled pottery and glass artifacts and associated pigments. A brief overview

Abstract: The birth of Chemistry can be found in two main practices: (i) the Arts du feu (ceramic and glass, metallurgy, i.e., inorganic and solid state chemistry) and (ii) the preparation of remedies, alcohols and perfumes, dyes, i.e., organic and liquid state chemistry)...

Bulk proton dynamics in anhydrous perovskites – Elastic, quasi- and in-elastic neutron scattering studies

Abstract: Thanks to their high proton conductivity at medium temperature, perovskite ceramics are promising electrolytic membranes of fuel cells, water steam electrolysers and CO2/syngas converters. Prior to such applications, some important aspects need to be clarified: (i) the real content of bulk protons, (ii) the optimum temperature range of proton dynamics and (iii) the true proton nature...
