Synthesis of silica supported ni and cu catalyst for carbon dioxide methanation reaction حسب Aheed, Ahmed

"…In addition, the used catalysts after the reaction were characterized using similar techniques to evaluate the effect of reaction conditions on active phase and SiO2 support. The 1%Ni on SiO2 catalyst shows good activity for CO2 conversion to CH4 till 450ºC, thereafter CH4 formation decreased and CO increased and remains the only product at 650ºC. …"

Role of TiO2 and carbon nanotubes on polyethylene, and effect of accelerated weathering on photo oxidation and mechanical properties حسب Zagho M.M.

"…Addition of CNTs had negligible effect on the tensile strength but it kept the same approximate value of the original before the accelerated weathering (e.g., 23.2 MPa for 1 wt% of CNTs). CNTs also protected the samples even with the presence of TONPs because of the absorbance and antioxidants effects. …"
