A comparative study of experimental configurations in synchrotron pair distribution function
(MDPI - Publisher of Open Access Journals, 2019-04-25)
The identification and quantification of amorphous components and nanocrystalline phases
with very small crystal sizes, smaller than ~3 nm, within samples containing crystalline phases is
very challenging. However, this ...
Difracción de rayos-x (DRX) y cementos: desde la investigación hasta el control de calidad
(2019-06-20)
Los materiales de construcción son componentes complejos de gran interés comercial. Por ello, el conocimiento cuantitativo de su mineralogía a través de la difracción de rayos X (DRX) es de crucial importancia para optimizar ...
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 ...
Powder diffraction at ALBA synchrotron
(2015-03-23)
This talk is devoted to explain the uses of powder diffraction at MSPD (material science and powder diffraction) of ALBA synchrotron light source. General characteristics of the beamline are: Station 1 - High Pressure ...

Synthesis of active Belite-Alite-Ye'elimite clinker (BAY)
(2016-06-29)
Ordinary Portland cement (OPC) is an environmentally contentious material, as for every ton of OPC produced, on average, 0.97 tons of CO2 are released. Ye'elimite-rich cements are considered as eco-cements because their ...
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 pressure and temperature spinning capillary cell for in-situ synchrotron X-ray powder diffraction
(2019)
In situ research of materials under moderate pressures (hundreds of bar) is essential in many scientific fields. These range from gas sorption to chemical and biological processes. One industrially important discipline is ...
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 ...
Multifunctional lanthanum tetraphosphonates: Flexible, ultramicroporous and proton-conducting hybrid frameworks
(The Royal Society of Chemistry, 2012)
A new flexible ultramicroporous solid, La(H5DTMP)·7H2O (1), has been crystallized at room temperature using the tetraphosphonic acid H8DTMP, hexamethylenediamine-N,N,N′,N′-tetrakis(methylenephosphonic acid). Its crystal ...
