Phase Stability and Electronic Structure of Iridium in the Mbar range under Shock Compression

Emanuele COLONNA · Ilaria CARLOMAGNO · Nicolas SEVELIN-RADIGUET · Jose Luis RODRIGO RAMON (ORCID: 0009-0004-0485-238X) · y 4 más

Iridium belongs to the 5d transition metals and it is the only refractory metal with a face-centred cubic structure. The stability of its fcc structure under extreme conditions of pressure and temperature has been debated for years and so far, only a single HP-HT melting point was experimentally detected. In addition,...

The IBS BAG includes teams from IBS (Grenoble) and external groups from CEA-Cadarache (St Paul lez Durance) and IRBA (Brétigny-sur-Orge). We study the structure-function relationships of proteins with a focus on human health, biotechnology and methodology. Most of the projects are a continuation of the MX-2586 proposal...

Unveiling Copper Adaptation Mechanisms in Bacteria: Insights from Bufferin-Copper Complexes via X-ray Absorption Spectroscopy

Francesco STELLATO · Olivier PROUX · Rachele CESARONI · Emiliano DE SANTIS

A necessary metal that is toxic in excess, copper induces adaptive responses in bacteria. Bacterial resistance or tolerance to this agent has thus become a problem in healthcare and agriculture. We identified a new mechanism for copper adaptation based on post-translationally modified peptides called ‘bufferins’ that e...

A tale of two triplets. Optical properties of TIPS-tetracene

Hoven, K. van den (Koen) · Christianen, P.C.M. · Engelkamp, H.

In this thesis we present the results obtained with optical experiments on single-crystalline samples of TIPS-tetracene (5,12-bis((triisopropylsilyl)ethynyl)tetracene). These measurements have been performed in high magnetic fields (0–38 T) and at low temperatures (0.3–50 K). Under these extreme circumstances we have e...

X-ray nano-tomography of mitochondria in neuroglioma cells

Montserrat SOLER LOPEZ · Caroline BISSARDON · Samira ACAJJAOUI · Ilian BOUKHERROUBA · y 1 más

Alzheimer's disease (AD) research aims to understand its pathogenesis for better diagnostics and treatments. Neurons, reliant on oxidative phosphorylation (OXPHOS) for energy, are severely impacted by mitochondrial dysfunction, closely linked to AD. A key feature of AD is amyloid aggregates, mainly Aβ(1-42) peptides, a...

Redox control on the oxidation state of bridgmanite and CF phase in basaltic assemblages and the origin of retrograde bridgmanite inclusions

Giacomo CRINITI (ORCID: 0000-0002-9414-523X) · Dimitrios BESSAS

Experimental determination of phase equilibria at high pressure and high temperature is pivotal to interpreting geophysical and geochemical data that can help decipher the mineralogical composition of the Earth’s deep interior. Oxygen fugacity is one of the key variables affecting the stability of minerals at high pres...

Chiral magnons in the metallic altermagnet CrSb

Liam SCHMIDT · Alberto DE LA TORRE · David ANDERSEN · Zubia HASAN · y 1 más

CrSb has been identified as a prominent candidate for observing altermagnetic (AM) chiral-split magnon spectra. AMs are novel spintronic platforms due to their strong time reversal symmetry-breaking responses akin to ferromagnets and fully compensated magnetization typical of collinear antiferromagnets (AFMs). CrSb ord...
