Evaluation of LaBO3 (B=Mn, Cr, Mn0.5Cr0.5) perovskites in catalytic oxidation of trichloroethylene
In this study, La–Mn–Cr perovskite-type catalysts were synthesized as LaMnO3,LaCrO3, and LaMn0.5Cr0.5O3 by a microwave-assisted gel-combustion method. They were then calcined at 600oC for 5h in a...
متن کاملInvestigation of effect of magnetic ordering on structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) using ab initio method
Structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) were studied for each of three magnetic configurations nonmagnetic, ferromagnetic, and antiferromagnetic by using density functional theory in generalized gradient approximations (GGA) and strong correlation correction (GGA + U). Due to magnetic transition from antiferromagnetic to nonmagnetic phase, an electr...

The optical properties of perovskites at ambient temperatures are important both to the design of optimised solar cells as well as in other areas such as the refinement of electronic band structure calculations. Limited previous information on the optical modelling has been published. The experimental fitting parameters for optical constants of CH3NH3PbI3-x Cl x and CH3NH3PbI3 perovskite films ...
متن کاملISOGEOMETRIC TOPOLOGY OPTIMIZATION OF STRUCTURES CONSIDERING WEIGHT MINIMIZATION AND LOCAL STRESS CONSTRAINTS
The Isogeometric Analysis (IA) is utilized for structural topology optimization considering minimization of weight and local stress constraints. For this purpose, material density of the structure is assumed as a continuous function throughout the design domain and approximated using the Non-Uniform Rational B-Spline (NURBS) basis functions. Control points of the density surface are...
متن کاملLead halide perovskites: Challenges and opportunities in advanced synthesis and spectroscopy
Hybrid lead perovskites containing a mixture of organic and inorganic cations and anions have led to solar cell devices with performance and stability that are better than those of their single-halide analogs. 207Pb solidstate nuclear magnetic resonance and single-particle photoluminescence spectroscopies show that the structure and composition of mixed-halide and likely other hybrid lead perov...
