Experimental and theoretical investigations on structural and vibrational properties of melilite-type Sr2ZnGe2O7 at high pressure and delineation of a high pressure monoclinic phase

Achary, S. Nagabhusan; Errandonea, Daniel; Santamaría-Pérez, David; Gomis, O.; Patwe, Sadiqua J.; Manjón Herrera, Francisco Javier; Rodríguez Hernández, Plácida; Muñoz, Alfonso; Tyagi, Avesh Kumar (American Chemical Society, 2015-07-06)

We report a combined experimental and theoretical study of melilite-type germanate, Sr2ZnGe2O7, under compression. In situ high-pressure X-ray diffraction and Raman scattering measurements up to 22 GPa were complemented ...
Experimental and theoretical investigations on the polymorphism and metastability of BiPO4

Achary, S. N.; Errandonea, Daniel; Muñoz, Alfonso; Rodríguez Hernández, Plácida; Manjón Herrera, Francisco Javier; Krishna, P. S. R.; Patwe, S. J.; Grover, V.; Tyagi, A. (Royal Society of Chemistry, 2013)

In this work we report the metastability and the energetics of the phase transitions of three different polymorphs of BiPO4, namely trigonal (Phase-I, space group P3(1)21), monoclinic monazite-type (Phase-II, space group ...
