Nanocomposites based on α-MnO2, reduced graphene oxide (rGO)-based α-MnO2, and Fe-doped α-MnO2 were successfully synthesized via the hydrothermal method. These materials were investigated for their potential applications in supercapacitors and photocatalytic dye degradation. This investigation involves a phase transition from α-MnO2 to the cubic phase of α-Mn2O3, as revealed by X-ray diffraction (XRD) analysis. The electrochemical performance and photocatalytic activity were significantly enhanced ...

Pure and Mn-doped ZnO nanoflowers were successfully synthesized by the hydrothermal technique. Doping of Mn into ZnO lattice exhibits formation of oxygen vacancies and surface modifications into ZnO lattice was investigated by XPS spectra and AFM analysis. During the photocatalytic performance, vacancies create the trap centers for photogenerated electrons hence the electron–hole recombination is effectively inhibited. These formed oxygen vacancies along with enhanced surface area are due to Mn ...

Core-shell nanoparticles of Co (0%, 3%, and 5%) doped Ni/NiO and incorporated (5 mg) graphene oxide (GO) sheets were synthesized by a sol-gel auto-combustion method. X-ray absorption near edge structure (XANES), extended X-ray absorption fine structure (EXAFS) and pair distribution function measurements were employed for the determination of the local structure and structural properties of the samples. Due to the effect of Co doping the bond lengths of all coordinate atoms were varied. The microstructural ...

The fundamental atomic structure of pure and Co doped ZnS nanowires has been studied using pair distribution function (PDF) analysis. It was confirmed that samples have hexagonal (wurtzite) structure. The interatomic distance was calculated using PDF analysis. It was observed that the energy band gap decreases as Co content increases.

Ptychobothridean genera like Senga and Circumoncobothrium are the common parasites of fresh water fishes. The genotypic study of these parasites was taken by RAPD. The RAPD profile of these two parasites were not similar to each other as depicted by the band pattern in picture. These results suggest the presence of inter-specific polymorphism among cestode parasites of two different genera for RAPD analysis. The present study demonstrated that genetic differentiation of cestode parasites could be ...

In the reinforced concrete column to footing connection design, the region around the column is exposed to punching shear failure. This is an undesirable failure since it results in a brittle failure and it governs the strength of the footing in column to footing connection. The shear stresses that act around the perimeter of the column tend to punch through the footing and develop a failure surface in the form of a truncated cone or pyramid shape. In this research, a nonlinear finite element modelling ...
