The crystallisation behaviour in the SrCl2–Na2SO4–H2O system at room temperature is strongly modified by the presence of dissolved silicon. Homogeneous nucleation experiments show that silicon inhibits the formation of celestite while promoting [...]texto impreso
Pina Martínez, Carlos Manuel ; Fernández-Díaz, Lourdes ; Prieto Rubio, Manuel | Elsevier Science B.V. | 1997The crystallization sequences in the system (NH4)2SO4 Li2SO4-H20 at 50C have been studied for solutions with an initial [(NH4)2SO4]/[LizSO4] molar ratio higher than l. The crystal growth experiments were carried out under isothermal conditions i[...]texto impreso
Checa, Antonio G. ; Mutvei, Harry ; Osuna-Mascaró, Antonio J. ; Bonarski, Jan T. ; Faryna, Marek ; Berent, Katarzyna ; Pina Martínez, Carlos Manuel ; Rousseau, Marthe Rousseau ; Macías-Sánchez, Elena | 2013Nacre tablets of mollusks develop two kinds of features when either the calcium carbonate or the organic portions are removed: (1) parallel lineations (vermiculations) formed by elongated carbonate rods, and (2) hourglass patterns, which appear [...]texto impreso

Pina Martínez, Carlos Manuel ; Pimentel Guerra, Carlos ; Crespo López, Ángel | Elsevier Science B.V., Amsterdam. | 2020-08-05Dolomite is a carbonate mineral frequently found in sedimentary rocks from Proterozoic to Holocene. In the Iberian Peninsula, dolomites appear in a wide number of geological formations and they can be considered as representative of dolomites cr[...]texto impreso
Pina Martínez, Carlos Manuel ; López-Acevedo, María Victoria | International Union of Crystallography | 2016A careful inspection of the drawings and baked clay models created by the mineralogist Romé de L’Isle in the 18th century has revealed the existence of a number of intriguing forms with pentagonal symmetries. These forms cannot be classified in [...]texto impreso
Benages-Vilau, Raúl ; Calvet, Teresa ; Cuevas Diarte, Miguel Ángel ; Pimentel, Carlos ; Pina Martínez, Carlos Manuel | American Chemical Society | 2013In this article, we present a study of the epitaxial growth of nitratine (NaNO3) on calcite (CaCO3) from ethanolic solutions. By using sodium nitrate saturated solutions in ethanol we were able to observe the initial stages of nitratine crystall[...]texto impreso
Pimentel Guerra, Carlos ; Gnecco, Enrico ; Pina Martínez, Carlos Manuel | American Chemical Society | 2018Growth of otavite (CdCO3) and spherocobaltite (CoCO3) has been promoted on dolomite (10.4) surfaces at room temperature by immersing cleaved dolomite crystals in highly supersaturated solutions with respect to those phases. In situ atomic force [...]texto impreso
