Clumped isotope fractionation during phosphoric acid digestion of carbonates at 70°C

The application of clumped isotopes (Delta(47)) in carbonate minerals as a sensitive temperature proxy in paleo-environments depends on a well-constrained clumped isotope fractionation for the necessary step of phosphoric acid digestion of the carbonate mi ...

Anisotropic volumetric behaviour of Opalinus Clay shale upon suction variation

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci, Alberto Minardi

Opalinus Clay shale is under consideration to serve as the host geomaterial for the underground storage of nuclear waste in Switzerland. Water retention behaviour and anisotropic behaviour represent two main features of this geomaterial; however, a compreh ...

Ionic Liquid Control Crystal Growth to Enhance Planar Perovskite Solar Cells Efficiency

Michael Graetzel, Shaik Mohammed Zakeeruddin, Kurt Schenk, Fabrizio Giordano, Ulf Anders Hagfeldt, Michael Saliba, Jingshan Luo, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski, Jiyoun Seo, Amita Ummadisingu, Taisuke Matsui, Mahboobeh Hadadian

Ionic liquids can retard the perovskite crystallization with the aim to form compact films with larger and more uniformly distributed grain size. The ionic liquid driven crystallization is exploited to prepared a record planar perovskite solar cell with st ...

Dynamics of Photocarrier Separation in MAPbI3 Perovskite Multigrain Films under a Quasistatic Electric Field

Jacques-Edouard Moser, Joël Teuscher, Arun Aby Paraecattil, Jelissa Risse, Vytenis Pranculis

Applying time-resolved electroabsorption spectroscopy for the first time to methylammonium lead triiodide perovskite (MAPbI3) thin films under reverse bias, we monitored optically the ultrafast evolution of the local counter-electric field produced by the ...

Environmental Mineralogy: New challenges, new materials

Rizlan Bernier-Latmani

The close links between mineralogy and materials science are leading to major developments in how society deals more effectively with energy and environmental challenges. The fast expanding field of "environmental mineralogy" helps mitigate major environme ...

Ductile flow in sub-volcanic carbonate basement as the main control for edifice stability: New experimental insights

Marie Estelle Solange Violay

Limestone in volcanic basements has been identified as a hazard in terms of edifice stability due to the propensity of calcite to decompose into lime and CO2 at high temperatures (>600 °C), causing a decrease in mechanical strength. To date, such hypoth ...

Toward Demystifying the Mohs Hardness Scale

Jean-François Molinari

Today, the Mohs scale is used profusely throughout educational systems without any persuasive understanding of the fundamental principles. Why one mineral has a scratch hardness over the next culminating in a scale of 1 (chalk) to 10 (diamond) has no atomi ...

The composite twin Higgs scenario

Riccardo Rattazzi, Andrea Wulzer, Davide Greco

Based on an explicit model, we propose and discuss the generic features of a possible implementation of the Twin Higgs program in the context of composite Higgs models. We find that the Twin Higgs quadratic divergence cancellation argument can be uplifted ...

The Maya blue nanostructured material concept applied to colouring geopolymers

Guillaume Habert, Aurélie Rosine Favier

Maya blue is an ancient nanostructured pigment synthetized by assembling indigo, a natural dye, with palygorskite, a microfibrous clay mineral. The novelty of our approach is to mimic "pre-Columbian nanotechnology" and to functionalize geopolymers with a s ...
