Lowering the Cu-O bond energy in CuO nanocatalysts enhances the efficiency of NH3 oxidation
Synthesis and structural characterization of the catalysts
The bimetallic CoBCu/Al2O3 catalyst (5 wt% Cu, 0.1 wt% Co) was synthesized by reducing Cu(NO3)2.3H2O and Co(NO3)2.6H2O together with NaBH4. CoHCu/Al2O3, with the same chemical…

Experimental design and analysis of toughness and modulus of rupture (MOR) of cement mortar reinforced with PET fibers
Test results of fresh mixes
The results (see Fig. 4) reveal a clear rheological trend in which the incorporation of PET fibers into mortar mixtures substantially impairs their workability. Approximately 50% of the mix designs exhibited…
