Greiner, Martina ; Fernández Díaz, Lurdes ; Griesshaber, Erika ; Zenkert, Moritz N. ; Yin, Xiaofei ; Ziegler, Andreas ; Veintemillas Verdaguer, Sabino ; Schmahl, Wolfgang W. | MDPI | 2018We present results of bioaragonite to apatite conversion in bivalve, coral and cuttlebone skeletons, biological hard materials distinguished by specific microstructures, skeletal densities, original porosities and biopolymer contents. The most p[...]texto impreso

Nindiyasari, Fitriana ; Griesshaber, Erika ; Zimmermann, Tanja ; Manian, Avinash Pradip ; Randow, Clemens ; Randow, Clemens ; Fernández Díaz, Lurdes ; Ziegler, Andreas ; Fleck, Claudia ; Schmahl, Wolfgang W. | Sage publications | 2016We synthesized cellulose/gypsum composites in the presence and absence of sodium alginate and investigated the interaction between the composite components as well as the mechanical properties of the final composites. Four different types of cel[...]texto impreso

Sánchez Pastor, Nuria ; Oehlerich, Markus ; Astilleros García-Monge, José Manuel ; Kaliwoda, Melanie ; Mayr, Christoph C. ; Fernández Díaz, Lurdes ; Schmahl, Wolfgang W. | Elsevier | 2016-02Ikaite (CaCO3 6H2O) is a metastable phase that crystallizes in nature from alkaline waters with high phosphate concentrations at temperatures close to 0 C. This mineral transforms into anhydrous calcium carbonate polymorphs when temperatures ris[...]texto impreso
Nindiyasari, Fitriana ; Ziegler, Andreas ; Griesshaber, Erika ; Fernández Díaz, Lurdes ; Huber, Julia ; Walther, Paul ; Schmahl, Wolfgang W. | American Chemical Society | 2015-06-03We investigate the effect of gelatin, agarose, and silica hydrogel with and without magnesium in the growth medium on calcite single crystal growth and aggregate formation. We characterize the hydrogel and the mineral by cryo-scanning electron m[...]texto impreso
Forjanes, Pablo ; Gómez Barreiro, Juan ; Morales, Juan ; Astilleros García-Monge, José Manuel ; Fernández Díaz, Lurdes | Royal Society of Chemistry | 2020Epitactic crystal growth plays a main role in the development of mineral processes and in the synthesis of advanced materials. Celestite (SrSO4) forms epitactic overgrowths on anhydrite (CaSO4) (100), (010) and (001) surfaces upon interacting wi[...]texto impreso

Astilleros García-Monge, José Manuel ; Pinto, André Jorge ; Gonçalves, Mário A. ; Sánchez Pastor, Nuria ; Fernández Díaz, Lurdes | American Chemical Society | 2013Metatorbernite (Cu(UO2)2(PO4)2·8H2O) has been identified in contaminated sediments as a phase controlling the fate of U. Here, we applied atomic force microscopy (AFM) to observe in situ the interaction between metatorbernite cleavage surfaces a[...]texto impreso
Astilleros García-Monge, José Manuel ; Pina Martínez, Carlos Manuel ; Fernández Díaz, Lurdes ; López Andrés, Sol | Wiley-VCH Verlag | 1998The crystallisation of malachite has been studied in a system involving the counter diffusion of Cu2+ and CO3 through a silica gel column at 25 ºC. In such a system supersaturation is a function of time and position along gel column. Under these[...]texto impreso
Morales, Juan ; Astilleros García-Monge, José Manuel ; Fernández Díaz, Lurdes | American Chemical Society | 2012The growth of anhydrite (100) surface in contact with supersaturated aqueous solutions (?anh = 1 -3.6) under low hydrothermal conditions (T = 60 -120 ºC) has been studied by use of a hydrothermal atomic force microscope (HAFM). Our observations [...]texto impreso
