Synthesis of silica supported ni and cu catalyst for carbon dioxide methanation reaction by 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. …”

Study of the Ion Interclation Mechanism in Mxene Membrane for the Water Treatment Applications by Helal, Mohamed Ibrahim Elsayed Ali Hussein

“…Unfortunately, these membranes can swell and shrink when in contact with water or under high temperatures. MXene (Ti3C2) is a two-dimensional early transition metal carbide-derived by the etching of MAX (Ti3AlC2) phases in fluoride-containing solutions, and it can be intercalated with cations due to its surface termination that makes MXene sheets Negatively charged. …”

Acute and chronic toxicity assessments of 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) on the calanoid copepod Acartia clausi: Effects on survival, development, sex-ratio and... by Emna, Djebbi

“…In contrast, embryonic stage revealed high vulnerability to E2 and EE2 acute effects. Embryos showed non-monotonic dose-response and hatching success was significantly reduced at low realistic concentrations of E2 (0.005, 0.5, and 5 μg L-1) and EE2 (0.05 and 5 μg L-1).Survival, development and sex ratio of A. clausi to EE2 exposure at 1 and 100 μg L-1 were also determined during a life cycle experiment. …”
