This paper deals with some microscopic phenomena, which occur on crystal surfaces during growth from aqueous solutions. Since crystallisation and crystal-solution interactions are ubiquitous in nature, their study is of relevance for a better un[...]texto impreso
In this article, we first present and discuss eighteenth-century descriptions of minerals that contributed decisively to the development of crystallography. Remarkably, these old crystallographic descriptions included morphologies with symmetrie[...]texto impreso
In this paper we present results of a study of the crystallisation behaviour of the dolomite-analogues norsethite and PbMg (CO3)2 at room temperature and atmospheric pressure. Whereas precipitation of norsethite was previously obtained by mixing[...]texto impreso
Natural sciences have experienced important developments when the insights into both matter and its interaction with the environment advanced to the next scale in space and time – irrespective whether the direction was towards larger or smaller [...]texto impreso

Sánchez Pastor, Nuria ; Pina Martínez, Carlos Manuel ; Fernández-Díaz, Lourdes | Elsevier Science B.V., Amsterdam. | 2006This paper deals with the relationship between habit and compositional changes in crystals of the BaxSr1xSO4 solid solution at 25 8C and 1 atm. Crystals corresponding to the whole range of compositions of the BaxSr1xSO4 solid solution have been [...]texto impreso

Pimentel, Carlos ; Shinto, Varghese ; Seong-Jun, Yoon ; Soo Young, Park ; Johannes, Gierschner ; Enrico, Gnecco ; Pina Martínez, Carlos Manuel | Institute of Physics (Great Britain) | 2016Organic semiconductors (OSC) are attracting much interest for (opto)electronic applications, such as photovoltaics, LEDs, sensors or solid state lasers. In particular, crystals formed by small ?-conjugated molecules have shown to be suitable for[...]texto impreso
Astilleros García-Monge, José Manuel ; Pina Martínez, Carlos Manuel ; Fernández-Díaz, Lourdes ; Putnis, Andrew | Elsevier Science Ltd | 2003In this paper, we present a brief review of the thermodynamic equilibrium of binary solid solution–aqueous solution (SS-AS) systems and derive an expression hat allows us to evaluate the supersaturation or undersaturation of a given aqueous solu[...]texto impreso
Koishi, Ayumi ; Fernandez Martinez, Alejandro ; Van Driessche, Alexander E. S. ; Michot, Laurent J. ; Pina Martínez, Carlos Manuel ; Pimentel Guerra, Carlos ; Lee, Byeongdu ; Montes-Hernandez, German | American Chemical Society | 2019Because of the widespread presence of foreign substrates in natural settings, mineral precipitation usually occurs via heterogeneous nucleation. This process is controlled by the interplay between the fluid supersaturation and interfacial energi[...]texto impreso
Kawai, Shigeki ; Pina Martínez, Carlos Manuel ; Bubendorf, Alexander ; Fessler, Gregor ; Glatzel, Thilo ; Gnecco, Enrico ; Meyer, Ernest | IOP publishing ltd | 2013We have investigated the morphology and structure of dolomite MgCa.CO3/2.104/ surfaces by bimodal dynamic force microscopy with flexural and torsional resonance modes in ultra-high vacuum at room temperature. We found that the surface slowly dec[...]texto impreso
Fernández-Díaz, Lourdes ; Pina Martínez, Carlos Manuel ; Astilleros García-Monge, José Manuel ; Sánchez-Pastor, Nuria | Mineralogical Society of America | 2009In this paper, we present an experimental study of the interaction between gypsum (010) surfaces and aqueous solutions of Na2CO3 with different concentrations. This interaction leads to the carbonatation (i.e., the transformation into carbonate [...]texto impreso
Pina Martínez, Carlos Manuel ; Enders, Michael ; Putnis, Andrew | Elsevier Science B.V., Amsterdam. | 2000In this paper we present a new approach to the problem of the crystallisation in solid solution–aqueous solution (SS–AS) systems, in which two main controlling factors have been considered: (i) the supersaturation state of the multicomponent sol[...]texto impreso
Astilleros García-Monge, José Manuel ; Pina Martínez, Carlos Manuel ; Fernández-Díaz, Lourdes ; Putnis, Andrew | Elsevier Science Ltd | 2000In situ atomic force microscopy (AFM) experiments have provided information about the effect of Ba21 on crystal growth of calcite {101¯4} surfaces. The microtopographic features observed have been interpreted by considering both the structural c[...]texto impreso
Sánchez Pastor, Nuria ; Pina Martínez, Carlos Manuel ; Fernández-Díaz, Lourdes ; Astilleros García-Monge, José Manuel | Elsevier | 2006The growth of barite {001} and {210} faces from aqueous solutions moderately supersaturated with respect to barite (?barite ? 12 for experiments on {001} surfaces and ?barite ? 7 for experiments on {210} surfaces) and bearing different concentra[...]
