Nowadays, CO2 capture is a vital technology to notably reduce the uncontrolled released emissions. using graphene oxide, derivative of graphene, has become tremendous interest due its unique morphology. In this present work, oxide (GrO) was synthesized under ultrasound irradiation according modified Hummers’ method and performance examined. The X-ray powder diffraction (XRD) Fourier transform i...

the zonouz kaolin deposit is located ~15 km northeast of marand, east-azarbaidjan province. based on physical features in field investigations, such as color, five distinct kaolin types including (1) white, (2) lemon, (3) gray, (4) brown, and (5) yellow are distinguished in the deposit. field evidence and petrographic studies indicate that the deposit is genetically close to trachy-andesite roc...

As healthcare resources become increasingly scarce due to growing demand and stagnating budgets, the need for effective priority setting and resource allocation will become ever more critical to providing sustainable care to patients. While societal values should certainly play a part in guiding these processes, the methodology used to capture these values need not necessarily be limited to mul...

In this work, we have modified a synthesized Y-type zeolite (Si/Al = 2.5), with three different amines to investigate of the influence of adsorbent’s surface modification on CO2 selectivity over CH4. The pristine and amine-functionalized NaY zeolites were characterized by X-ray diffraction (XRD), thermal gravimetric analysis (TGA), Fourier transform infrared (FT-IR), and N2 adsorption. The resu...

Molybdenum adsorption behavior was investigated on various crystalline and x-ray amorphous Al and Fe oxide minerals, clay minerals, CaC@, and arid-zone calcareous and noncalcareous s soils. Molybdenum adsorption on botb Al and Fe oxides exhibited a maximum at low pH extending to about pH 4 to 5. Above pH 5 adsorption decreased rapidly, with little adsorption occurring above pH 8. Molybdenum ads...
