Ochre pigments, in all their varieties, have played a key role in Northwestern Argentinian pottery for more than 2000 years. Present in different styles, they are combined with other colours on surface paints. This artic...

Cerium-based materials were intensively studied in last years because of their high oxygen storage capacity (OSC) associated to the reversible Ce4+ Ce3+ process and their properties closely related to the defect chemistr...

Soil microbial properties are increasingly recognised as a crucial metric of both soil health and soil carbon dynamics. However, these properties remain underutilised due to challenges in quantifying these properties at ...

The fabrication of hierarchical zeolite structure and rational modulation of Ti active sites in TS-1 zeolite are both recognized as critical factors for improving catalytic performance in selective oxidation reactions. H...

In this work TiO2 modified with nitrogen was synthesized by sol-gel method from the hydrolysis of titanium isopropoxide with urea solution in different concentrations so that the theoretical N/Ti molar ratio was equal to...

Catalytic methane decomposition (CMD) offers a direct pathway to CO2-free hydrogen by converting CH4 into H2 and solid carbon. However, its application is constrained by the need for efficient heat delivery to the cataly...
