Can inclusions be symmetry broken? Murri and co-authors recently studied the role of symmetry-breaking strains in quartz inclusions entrapped in zircon by ab initio simulations. They discovered that for deformations expected for real cases the...

Diamond-Graphene Composite Nanostructures In their latest paper Mara and co-workers describe two new families of diamond-graphene (diaphite) phases constructed from layered and bonded sp3 and sp2 nanostructural units and provide a framework for...
Read moreCooling history and emplacement of a pyroxenitic lava as proxy for understanding Martian lava flows
Cooling history and emplacement of a pyroxenitic lava as proxy for understanding Martian lava flows Our PhD student Mara Murri at her second Scientific Reports paper for this year! Congratulations!! She has now concluded her studies on the...
Read moreQuantifying hexagonal stacking in diamond
Once again on the shock impact topic. In her new nice manuscript in Scientific Reports Mara Murri presents some of the recent considerations about structural disorder in the form of complex combinations of cubic and hexagonal stacking motifs...
Read moreViscosity experiments at superliquidus temperatures
Rheology is the key factor to understand dynamic processes and behavior of magma rising through volcanic conduit and lava emplacement on Earth or other terrestrial planets. Today we can monitor the evolution of magma and volcanic mixtures by...
Read moreStructure and properties of quartz under non-hydrostatic stress
Mara Murri marks the beginning of the new year with an incredibly nice paper showing the effect of non-hydrostatic stresses on the structure of alpha-quartz. This investigation carried out through ab initio hybrid Hartree–Fock/DFT simulations...

METEORITI, CRATERI DA IMPATTO E TUNNEL DI LAVA: IL CONTRIBUTO DELLE SCIENZE GEOLOGICHE ALLO STUDIO DEI MATERIALI EXTRATERRESTRI E DEGLI ANALOGHI PLANETARI E ALLA PREPARAZIONE DELLE FUTURE MISSIONI ESPLORATIVE PLANETARIE Mara Murri gave a really...
Read morestRAinMAN software now released
In his new paper published in Zeitschrift fuer Kristallographie Ross Angel explains the development of the past year that led to the current version of the stRAinMAN program. This allows the strains acting on inclusions trapped in their host to...
Read moreDetermine strains on inclusions from Raman measurements
In her new paper published on American Mineralogist, Mara Murri, describes a method for determining the strains in quartz inclusions from Raman spectroscopy using the concept of the phonon-mode Grüneisen tensor, which we determine by ab initio...
Read moreExperimental validation of intracrystalline “geothermometry” for rocks
In this paper, we test the available experimental calibrations for clino and orthopyroxenes as geothermometer by determining their site in synthetic samples grown from a hydrous nepheline basanite in a piston-cylinder apparatus at 1050 °C at...
