Manganese dioxide (α-MnO2) nanorods with diameters of about 5–15 nm and lengths of 100–150 nm were synthesized by a simple co-precipitation method, and the degradation mechanism of rhodamine B (RhB) at different pH levels was investigated. The α-MnO2 nanorods exhibited a high efficiency and rapid removal rate of RhB, which reached about 97.5% withi...

Structural, mechanical and optoelectronic features of zinc-blende Cd1−x−yZnxHgySe quaternary alloys as well as allied binary compounds and ternary alloys have been investigated through first-principle calculations. Computed elastic stiffness constants ensure that each specimen is mechanically stable, ductile, elastically anisotropic and compressibl...

To the best of our knowledge, we report for the first time the growth of brownmillerite Ca2Fe2O5 (CFO) single crystals under Argon (Ar) only ambience by optical floating zone (OFZ) technique and compare its structural and spectroscopic properties with CFO single crystals grown by OFZ method under air and oxygen (O2) atmospheres. Single-crystal X-ra...

Cobalt (Co)-doped zinc oxide (ZnO) diluted magnetic semiconductor thin films were grown using a low-cost spray pyrolysis technique. X-ray diffraction (XRD) studies show that the films crystallize in the pure wurtzite structure. No evidence of the formation of secondary phases like Co clusters, CoO or Co3O4 were detected from XRD studies. Scanning e...

The study of intermolecular interactions is of great importance. This study attempted to quantitatively examine the interactions between cysteine (C3H7NO2S) amino acid molecule with pristine boron nitride, Al-doped boron nitride and carbon boron nitride nanotubes (BNNT, BNAlNT, BC2NNT, respectively) in vacuum. Quantum mechanical studies of such sys...

This study reports the sintering of Mg0.8Zn0.2TiO3 (MZT) with an addition of K0.5Na0.5VO3 (KNV) and Bi2O3. The sintering temperature was performed at 950°C for 4 h and attained a maximum relative density of 97.71% in a composition of 85% mol MZT–10% mol KNV–5% Bi2O3 (MZT85). Structure, microstructure and phase present in the sample were analysed us...

Non-toxic lead-free potassium sodium niobate (K0.5Na0.5NbO3) ceramics were manufactured by using solid-state reaction method. The influences of excessive alkali metal (Na, K) ions concentration (0–20%) on their structural and electro-optical properties have been examined systematically. The structural properties confirmed the perovskite phase havin...

Plasma polymerized 2-vinylpyridine (PP2VP) thin films have been synthesized under glow discharge using a capacitively coupled system. In the scanning electron microscope images, surface morphology of the PP2VP thin films is observed to be very smooth and crack free. Fourier transform infrared spectra of the thin films clearly indicate that structur...

The present investigation highlights the formation of dodecyl sulfate (SDS)-functionalized binary Co/Ni hydroxide using a facile sol–gel method. The effect of (SDS) surfactant ions on hydroxides was studied using X-ray diffraction and Fourier transform infrared spectroscopy. The nanoflakes and their vertically aligned uniform distribution were scru...
