Epitaxial growth of calcite on dolomite and kutnahorite (104) surfaces has been promoted at room temperature by immersing cleavage rhombohedra of these minerals in highly supersaturated solutions with respect to calcite (?calcite = [a(Ca2+)·a(CO[...]texto impreso
Sánchez Pastor, Nuria ; Pina Martínez, Carlos Manuel ; Astilleros García-Monge, José Manuel ; Fernández-Díaz, Lourdes ; Putnis, Andrew | Elsevier | 2005In situ AFM experiments have been conducted in order to obtain information about kinetics of celestite epitaxial growth on barite. Growth has been promoted by passing aqueous solutions supersaturated with respect to celestite over freshly cleave[...]texto impreso
Agmon, Liron ; Shahar, Itai ; Yosufov, Danny ; Pimentel Guerra, Carlos ; Pina Martínez, Carlos Manuel ; Gnecco, Enrico ; Berkovich, Ronen | Nature Publishing Group | 2018-03-16Friction force microscopy (FFM) in aqueous environments has recently proven to be a very effective method for lattice-resolution imaging of crystal surfaces. Here we demonstrate the use of ethanol for similar measurements on water-soluble materi[...]texto impreso

Pina Martínez, Carlos Manuel ; López Andrés, Sol ; Rull Pérez, Fernando ; Prieto Colorado, Carmelo ; Fernández-Díaz, Lourdes ; Prieto Rubio, Manuel | Sociedad Española de Mineralogía | 1992The transformation of phosgenite into cerussite in a diffusing-reacting system has been studied. This transformation occurs in a narrow pH range. Mass-transfer and pH evolution in the system during the process was testified. The transformation d[...]texto impreso

Pimentel Guerra, Carlos ; Mougin, Karine ; Gnecco, Enrico ; Pina Martínez, Carlos Manuel | Elsevier | 2020-11-15Cleaved dolomite (CaMg(CO3)2) crystals were immersed in supersaturated, saturated, and undersaturated solutions with respect to zabuyelite (Li2CO3), and the growth process was characterized using atomic force microscopy (AFM) and scanning electr[...]texto impreso
Pina Martínez, Carlos Manuel ; Pimentel Guerra, Carlos ; Gnecco, Enrico | Springer International Publishing Switzerland | 2015Lateral Force Microscopy (LFM) is a very suitable technique to investigate the structure and reactivity of mineral surfaces in liquids. Studies performed in the last two decades have shown that the dissolution and growth of mineral surfaces imme[...]texto impreso
YuHang, Chen ; Asenjo Barahona, Agustina ; Sánchez Pastor, Nuria ; Fernández-Díaz, Lourdes ; Gómez Herrero, Julio ; Pina Martínez, Carlos Manuel | Elsevier | 2007Crystal growth has been promoted in the fluid cell of an Atomic Force Microscope (AFM) by passing Ba–Sr–SO4 aqueous solutions over barite (001) cleavage surfaces. Steps advance in structural continuity with the original barite (001) surfaces and[...]texto impreso
Pina Martínez, Carlos Manuel ; Fernández-Díaz, Lourdes ; López García, José Ángel ; Prieto Rubio, Manuel | Elsevier Science B.V. | 1995Isothermal crystallization in the system Na2SO4-Li2SO4-H20 was carried out at 50°C by "salting out" in a tetrametoxysilane (TMS) gel medium. Under these conditions the solid phases that can crystallize are Na2SO4, Li2SO4 . H20 and ?-LiNaSO4, dep[...]texto impreso
The trigonal b-LiNaSO4 low temperature polymorph belongs to the family of double sulphates with general formula LiMSO4 (M ¼ Na; NH4, Rb,y), which have very specific electrical properties. In this paper we present the b-LiNaSO4 theoretical growth[...]texto impreso
In this paper, we present high-resolution friction force microscopy (FFM) images of the (100) face of kyanite (Al2SiO5) immersed in water. These images show an almost rectangular lattice presumably defined by the protruding oxygen of AlO6 polyhe[...]texto impreso
In this paper we present high resolution atomic force microscopy (AFM) images of dolomite (104) cleavage surfaces immersed in pure water. These images show a rectangular lattice with surface unit cell dimensions in general agreement with those d[...]
