Las figurillas de terracota del Teatro Romano de Málaga (España): Un estudio arqueométrico
(Sociedad Española de Cerámica y Vidrio, 2014-06)
Se han estudiado 22 terracotas figuradas feno-púnicas y romanas, de alto valor arqueológico y patrimonial. Las muestras
proceden de las excavaciones del Teatro romano de Málaga (España). El análisis realizado incluye ...
High-Throughput Synthesis of Pillared-Layered Magnesium Tetraphosphonate Coordination Polymers: Framework Interconversions and Proton Conductivity Studies
(MDPI, www.mdpi.com/journal/inorganics, 2018-09-11)
Novel pillared-layered framework materials were synthesized by high-throughput
or microwave-assisted methodology that contain Mg2+ and the zwitterionic linker HDTMP
(hexamethylenediamine-N,N,N0,N0-tetrakis(methylenephosphonic ...
Structural Variability in Multifunctional Metal Xylenediaminetetraphosphonate Hybrids
(American Chemical Society, 2013-07-24)
Two new families of divalent metal hybrid derivatives from the aromatic tetraphosphonic acids 1,4- and 1,3-bis(aminomethyl)benzene-N,N′-bis(methylenephosphonic acid), (H2O3PCH2)2−N−CH2C6H4CH2−N(CH2PO3H2)2 (designated herein ...
Tuning Proton Conductivity in Alkali Metal Phosphonocarboxylates by Cation Size-Induced and Water-Facilitated Proton Transfer Pathways
(American Chemical Society, 2014-12-20)
The structural and functional chemistry of a family of alkali-metal ions with racemic R,S-hydroxyphosphonoacetate (M-HPAA; M = Li, Na, K, Cs) are reported. Crystal structures were determined by X-ray data (Li+, powder ...
2D Corrugated Magnesium Carboxyphosphonate Materials: Topotactic Transformations and Interlayer “Decoration” with Ammonia
(American Chemical Society, 2012-06-29)
In this paper we report the synthesis and structural characterization of the 2D layered coordination polymer Mg(BPMGLY)(H2O)2 (BPMGLY = bis-phosphonomethylglycine, (HO3PCH2)2N(H)COO2−). The Mg ion is found in a slightly ...
Structure of stratlingite and effect of hydration methodology on microstructure
(ICE publishing, 2015)
Stratlingite, Ca4Al2(OH)12[AlSi(OH)8]2•2H2O, is an AFm phase which appears as hydration product of aluminum-rich cements. These binders may be calcium aluminate cements, calcium sulfoaluminate cements and also Belite Calcium ...
Tailored setting times with high compressive strengths in bassanite calcium sulfoaluminate eco-cements
(Elsevier, 2016-09)
This work deals with the hydration of a calcium sulfoaluminate (CSA) eco-cement prepared with bassanite and different additives (type and content) at a fixed water/CSA ratio of 0.5. Pastes prepared with bassanite show high ...
Structural variability in M2+ 2-hydroxyphosphonoacetate moderate proton conductors
(De Gruyter, 2017)
The structural variability of two series of Mg2+- and Zn2+- 2-hydroxyphosphonoacetates have been
studied in the range of 25–80 °C and 95 % relative humidity in order to correlate the structure with the
proton conductivity ...
Guest Molecule-Responsive Functional Calcium Phosphonate Frameworks for Tuned Proton Conductivity
(American Chemical Society, 2014-03-18)
We report the synthesis, structural characterization, and functionality of an open-framework hybrid that combines Ca2+ ions and the rigid polyfunctional ligand 5-(dihydroxyphosphoryl) isophthalic acid (PiPhtA). Ca-PiPhtA-I ...
High Proton Conductivity in a Flexible, Cross-Linked, Ultramicroporous Magnesium Tetraphosphonate Hybrid Framework
(American Chemical Society, 2012-07-03)
Multifunctional materials, especially those combining two or more properties of interest, are attracting immense attention due to their potential applications. MOFs, metal organic frameworks, can be regarded as multifunctional ...
