The luminescence of titanite (CaTiSiO5) [PDF]

Materials Research Bulletin, 1988
The luminescence of CaTiSiO5 crystals is reported. The emission band has its maximum at 520 nm. The results are discussed in connection with titanium compounds containing comparable titanate polyhedra.

Room‐Temperature Antiferroelectricity in Titanite (CaTiSiO5) Thin Films

Advanced Electronic Materials, EarlyView.
This study reports the first fabrication of titanite films featuring 1D chains of oxygen octahedra, along with the first observation of their antiferroelectric behavior at room temperature. A field‐induced ferroelectric phase is observed at ∼430 kV/cm, which is not reported in bulk titanite.

SYNTAXY OF TITANITE, AEGIRINE AND ECKERMANNITE IN ALKALI SYENITE PEGMATITES OF THE VISHNEVYE MOUNTAINS (SOUTH URALS) [PDF]

Минералогия, 2016
Crystallographic orientation of titanite intergrowths with aegirine and eckermannite was found in alkali syenite pegmatites of the Vishnevye Mountains: the titanite face ( 1 11) is parallel to pyroxene and amphibole face (010) and the titanite face (110)

Advancing Energy Materials by In Situ Atomic Scale Methods

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

U–Pb dating and Sm–Nd isotopic analysis of granitic rocks from the Tiris Complex : new constaints on key events in the evolution of the Reguibat Shield, Mauritania [PDF]

, 2012
The Reguibat Shield of N Mauritania and W Algeria represents the northern exposure of the West African Craton. As with its counterpart in equatorial West Africa, the Leo Shield, it comprises a western Archaean Domain and an eastern Palaeoproterozoic ...

Peixe Zircon as a Quality Control Reference Material in U‐Pb Geochronology by LA‐ICP‐MS

Geostandards and Geoanalytical Research, EarlyView.
Key Points Peixe#0 zircon was characterised for U‐Pb geochronology using CA‐ID‐TIMS, SIMS and a long‐term LA‐ICP‐MS data set. The consistent results establish Peixe#0 as a reference material for U‐Pb quality control. Trace element heterogeneity requires careful, CL‐guided spot selection.

Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

Meteoritics &Planetary Science, EarlyView.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...
