Physical-Properties of Oxygen-Deficient Co-Based Perovskites: Co(Sr1-xYx)O3–δ (0.05 ≤ x ≤ 0.4)

In this work, the syntheses and characterization of oxygen deficient perovskite cobalt oxides prepared under ambient pressure conditions with different “x” in the Co(Sr1–xYx)O3–; 0.05 ≤ x ≤ 0.4 series are reported. The system studied in the present investigation undergoes structural phase transition at room temperature from cubic to tetragonal symmetry. The samples with x ≥ 0.2 show a tetragon...

Synthesis of iron-based chemical looping sorbents integrated with pH swing carbon mineral sequestration.

The previously developed pH swing carbon mineral sequestration immobilizes the gaseous CO2 into a thermodynamically stable solid, MgCO3, using Mg-bearing minerals such as serpentine. This mineral carbonation technology is particularly promising since it generates value-added solid products: high surface area silica, iron oxide, and magnesium carbonate, while providing a safe and permanent stora...

Characterization of a Sol-gel Derived CuO/CuAl2O4 Oxygen Carrier for Chemical Looping Combustion (CLC) and Chemical Looping with Oxygen Uncoupling (CLOU) of Gaseous Fuels

The Comparison of Silica Gel-Alumina Sorbents for Separation of PAHs and PCBs

The aim of this research is to develop a silica gel and alumina column chromatography for separation of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) into two groups. This is achieved by optimizing the cut-off volume of eluting solvent and weight ratio of silica gel and alumina. In this process mixture of PAHs and PCBs divide in two groups and simultaneously o...
