Characterization of Ln4Al2O9 (Ln=Y, Sm, Eu, Gd, Tb) rare-earth aluminates as new high-temperature barriers
(Elsevier, 2018-06-01)
A family of cuspidine-type rare-earth (RE) aluminates with the general formula Ln4Al2O9 (Ln= Y, Sm, Eu, Gd, Tb) was prepared for potential use as thermal-barrier coating (TBC) materials with appropriate properties. Various ...
Designing multifunctional pigments for an improved energy efficiency in buildings
(Elsevier, 2017-07-15)
Materials science offers solutions that when are combined can offer important energy savings in the building sector. In this study, high reflectance coating and thermal storage capacity are combined with the aim of improving ...
Effect of the synthesis conditions on the properties of La0.15Sm0.35Sr0.08Ba0.42FeO3-a cathode material for SOFCs
(2017-09-13)
The perovskite La0.15Sm0.35Sr0.08Ba0.42FeO3-a has been prepared by the glycine nitrate (GNC) route, varying the fuel/oxidizer ratio (glycine/nitrate, G/N= 1 and 2) and cooling rate (slow cooling and air-quenched), in order ...
K2MnII2(H2O)2C2O4(HPO3)2: A New 2D Manganese(II) Oxalatophosphite with Double-Layered Honeycomb Sheets Stabilized by Potassium Ions
(The Royal Society of Chemistry, 2018-01-21)
A novel 2D metal oxalatophosphite K2MnII2(H2O)2C2O4(HPO3)2 (KMnCP) was hydrothermally synthesized and characterized. The hexagonal morphology and crystal growth faces of KMnCP were predicted by Bravais–Friedel–Donnay–Harker ...
Ionic liqids for the control of the morphology in poly(vinylidene fluoride-co-hexafluoropropylene) membranes
(Elsevier, 2018-10-05)
The development of polymer membranes with tailored micro-morphology and wettability is a demand in the areas of filtration, sensors, and tissue engineering, among others. The thermoplastic copolymer poly(vinylidene ...
