Pina Martínez, Carlos Manuel ; Putnis, Cristine Veta ; Becker, Udo ; Biswas, Subir ; Carrol, E.C. ; Bosbach, Dirk ; Putnis, Andrew | Elsevier | 2004The effect of five phosphonic acids (hydroxyethylene diphosphonic acid, HEDP; nitro trimethyl phosphonic acid, NTMP; methylene diphosphonic acid, MDP; amino methylene phosphonic acid, AMP; and sodium phosphonobutane tricarboxylic acid, PBTC) on [...]texto impreso
Fernández González, Ángeles ; Prieto Rubio, Manuel ; López Andrés, Sol ; Putnis, Andrew | Sociedad Geológica de España | 1996The complete series of the otavite-calcite solid has been synthesized by counter diffusion of CdClz + CaClz and CaCO] through a column of silica hydrogel. In this system there is a strong preferential partitioning of Cd in the solid phase, and o[...]texto impreso

Fernández González, Ángeles ; Prieto Rubio, Manuel ; Putnis, Andrew ; López Andrés, Sol | Mineralogical Society (Great Britain) | 1999Otavite-calcite solid solutions have been synthesized to investigate the factors which control the patterns of compositional zoning. The equilibrium partitioning of otavite between the aqueous and the solid phase can be described by means of a f[...]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
Pina Martínez, Carlos Manuel ; Fernández-Díaz, Lourdes ; Prieto Rubio, Manuel ; Putnis, Andrew | Elsevier Science Ltd | 2000The dissolution–reprecipitation reaction of phosgenite (Pb2Cl2CO3) to cerussite (PbCO3) has been observed in situ in a fluid cell of an atomic force microscope (AFM). The (001) face of phosgenite, in contact with static carbonated aqueous soluti[...]texto impreso

Godelitsas, Athanasios ; Astilleros García-Monge, José Manuel ; Hallam, K.R. ; Harissopoulos, Sotirios ; Putnis, Andrew | American Chemical Society | 2003Pure calcium carbonate (calcite and aragonite) solid materials of different particle size (100-200 ím fragments and millimeter-sized single crystals) were interacted with Pb in aqueous solutions at room temperature under atmosphericPCO2. In the [...]texto impreso
Prieto Rubio, Manuel ; Putnis, Andrew ; Fernández-Díaz, Lourdes ; López Andrés, Sol | Elsevier Science B.V. | 1994Nucleation in non-homogeneous diffusing-reacting systems occurs under a changing supersaturation. Under these conditions, the rate of creation of supersaturation determines the value of the supersaturation threshold at the nucleation time, i.e.,[...]texto impreso
Astilleros García-Monge, José Manuel ; Pina Martínez, Carlos Manuel ; Fernández-Díaz, Lourdes ; Putnis, Andrew | Elsevier Science B.V., Amsterdam. | 2003In situ atomic force microscopy (AFM) experiments, scanning electron microscopy (SEM) imaging and composition analysis, and X-ray diffraction have provided information about the growth, dissolution and transformation processes promoted by Sr2 + [...]texto impreso
Godelitsas, Athanasios ; Astilleros García-Monge, José Manuel ; Hallam, K.R. ; Löns, J. ; Putnis, Andrew | Mineralogical Society (Great Britain) | 2003The interaction of the {101¯4} cleavage surface of calcite with Hg(CH3COO)2 aqueous solutions with concentration of 5 mM Hg(II) (pH ?3.5), was investigated using microscopic and spectroscopic techniques. In situ atomic force microscopy experimen[...]texto impreso
Pina Martínez, Carlos Manuel ; Bosbach, Dirk ; Prieto Rubio, Manuel ; Putnis, Andrew | Elsevier Science B.V. | 1998Under moderate supersaturation conditions, crystal growth on the barite (0 0 1) surface takes place by the development of two-dimensional nucleation simultaneously with the advancement of molecular-height cleavage steps on the surface. The most [...]texto impreso
Pina Martínez, Carlos Manuel ; Becker, Udo ; Risthaus, Peter ; Bosbach, Dirk ; Putnis, Andrew | Nature Publishing Group | 1998Models of crystal growth have been defined by comparing macroscopic growth kinetics with theoretical predictions for various growth mechanisms. The classic Burton–Cabrera–Frank (BCF) theory predicts that spiral growth at screw dislocations will [...]texto impreso
Astilleros García-Monge, José Manuel ; Pina Martínez, Carlos Manuel ; Fernández-Díaz, Lourdes ; Putnis, Andrew | Elsevier Science Ltd | 2002Abstract—This paper deals with the growth behaviour of the Mn-Ca-CO3-H2O solid solution-aqueous solution system on calcite {1014} surfaces. This system represents a model example, which allows us to study the effect of a number of controlling fa[...]texto impreso
Astilleros García-Monge, José Manuel ; Pina Martínez, Carlos Manuel ; Fernández-Díaz, Lourdes ; Putnis, Andrew | Elsevier | 2003The effect of foreign ions on the growth of pure crystals from aqueous solution is an important topic addressed by both crystal growth, mineral and surface sciences. However, many aspects of the role played by those ions remain unclear. Our atom[...]
