Synthesis, crystal structure and structure–property relations of strontium orthocarbonate, Sr2CO4
(Acta Crystallographica Section B, 2021-02-09)Carbonates containing CO4 groups as building blocks have recently been discovered. A new orthocarbonate, Sr2CO4 is synthesized at 92 GPa and at a temperature of 2500 K. Its crystal structure was determined by in situ ... -
Carbonates from the ancient world's longest aqueduct: A testament of Byzantine water management
; ; ; ; (Geoarchaeology, 2021-05-06)
Abstract The fourth‐ and fifth‐century aqueduct system of Constantinople is, at 426 km, the longest water supply line of the ancient world. Carbonate deposits in the aqueduct system provide an archive of both archaeological ... -
A discussion on `Domain formation and phase transitions in the wurtzite‐based heterovalent ternaries: a Landau theory analysis'
; (Acta Crystallographica Section A, 2021-03-23)
Heterovalent ternary nitrides are considered one of the promising classes of materials for photovoltaics, combining attractive physical properties with low toxicity and element abundance. One of the front‐runner systems ... -
Numerically stable form factor of any polygon and polyhedron
(Journal of Applied Crystallography, 2021-03-25)Coordinate‐free expressions for the form factors of arbitrary polygons and polyhedra are derived using the divergence theorem and Stokes's theorem. Apparent singularities, all removable, are discussed in detail. Cancellation ... -
Stable Biological Production in the Eastern Equatorial Pacific Across the Plio‐Pleistocene Transition (∼3.35–2.0 Ma)
; ; ; ; ; ; (Paleoceanography and Paleoclimatology, 2021-04-08)
Abstract Upwelling within the Eastern Equatorial Pacific (EEP) Ocean is a key factor for the Earth's climate because it supports >10% of the present‐day biological production. The dynamics of upwelling in the EEP across ...
