X-ray powder diffraction applied to cement related phases: in-situ and high resolution applications
(2014-07-03)
XRPD is a powerful tool for material characterization in general, and for in-situ studies of chemical processes in particular. The use of an intense X-ray source, .i.e. synchrotron X-rays, coupled with fast X-ray detection ...
ALBA Synchrotron Light Source
(2015-03-23)
ALBA synchrotron light source (www.cells.es) is the largest Spanish research infrastructure that started full operation of its first 7 beamlines on February 2013. I will divide the talk in three parts: i) the general ...
Hydration studies of calcium sulfoaluminate cements blended with fly ash
(Elsevier, 2013)
The main objective of this work is to study the hydration and properties of calciumsulfoaluminate cement pastes
blended with fly ash (FA) and the corresponding mortars at different hydration ages. Laboratory X-ray ...
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 ...
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 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 ...
In situ high pressure powder diffraction study of proton conductors based on metal phosphonates
(2015-06-30)
Soft Porous Metal Organic frameworks (MOFs) are referred to as a class of coordination polymers that exhibit structural flexibility in response to guest interactions or physical stimuli [1]. By combining softness and ...
Proton conductivity of multifunctional metal phosphonate frameworks
(2015-03-23)
Metal phosphonates exhibit attractive characteristics for proton conductivity, such as tunable functionality, chemical and thermal stability and the existence of H-bond networks with acidic protons within their structure.1
In ...
Proton Conductors based on Metal Phosphonate Hybrid Materials for PEM Fuel Cells
(2014-06-25)
The necessity of energy and power generation is constantly growing. Fossils fuels are quickly becoming unsatisfactory substrates due to both their emission of pollutants and their finite expectancy. Fuel cells are one of ...
Photocatalytic behavior of phosphonate-based hybrid materials on dyes and phenols degradation
(2013-09-25)
There is increasing interest in using heterogeneous catalysis for mineralization of
organic pollutants. Within Advanced Oxidation Processes (AOPs), Photo-Fenton
reaction is one of the most efficient methodologies. To ...
