Science and technology of nanosized bimetallic oxide nanomaterials records the various properties and applications. Especially biomedical applications are viewed in particular due to its nanosized particle size. The present experimentation is reporting the microwave-assisted synthesis of nanosized bimetallic oxides like copper ferrite (CuFe2O4) and barium titanate (BaTiO3) by solid state combustion route using poly (vinyl alcohol) (PVA) as a fuel. The structural and morphological characterizations of the bimetallic oxide nanomaterials are performed out by X-ray diffraction (XRD) and scanning electron micrograph (SEM) tools respectively. These analyses report the crystalline nature of both samples. EDX spectral study is also undertaken to know the existence of different metals in the above-mentioned samples. Bonding nature of the bimetallic oxide samples were readied by Fourier transfer infrared (FT-IR) instrumentation. The study reviewed the varied vibrational modes confirms the phase formation of the samples. UV-Vis and thermal study of these bimetallic oxide samples are also studied extensively to know the thermal and absorption behavior respectively. TGA of both the samples are traced and are showing decomposition at rapid rate. In addition, the maximum absorption peaks due to π - π* transition confirms the sample formation. Antimicrobial activity of the prepared oxide samples was studied for antibacterial and antifungal behavior. Both samples showing considerable activity against various bacteria and fungi.

An experimental investigation was undertaken to study the Cobalt-based Stellite 6, powder deposited on SS 304 stainless steel substrate without any intermittent layer using an atmospheric plasma spray deposition process by varying the thickness of coating in the range of 74 µm, 128 µm, and 215 µm. The effect of coating thickness on metallurgical properties and corrosion resistance behavior was investigated. Optical microscopy, Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Spectroscopy (EDS) were employed to study the morphology of Stellite 6 coating. X-Ray Diffraction was used for structural analysis and to identify the phase formation. It was observed that the sample with 128 µm coating thickness provides the best result concerning microhardness and microstructure characteristics whereas the sample with 215 µm coating thickness provides the best corrosion resistance property. The reasons for the deviation were investigated and the factors responsible for the deviation were assigned in this investigation.

The Zinc doped calcium borate (Zn-CaB) was synthesized by the co-precipitation method. Zinc was known to exhibit a good antimicrobial effect without causing any environmental issues. However, the antimicrobial activity of zinc is relatively low as compared to silver or copper analogues. In the present investigation, an attempt was made to incorporate zinc in the matrix of calcium borates to enhance the antibacterial effect. Cosmetic products were made using the zinc-calcium-borates and the antibacterial/antifungal activity was evaluated and compared with the commercial products. The studies revealed that the antibacterial activity of Zn-CaB was equivalent to that commercially available product with a maximum of 99% reduction in bacterial strains and above 95% reduction in fungal strains. An attempt was made to incorporate a bacteriostatic effect on fabric by adding zinc-calcium-borates to detergent which exhibited prolonged antibacterial activity, even after 3 washing cycles. The cosmetic products were also evaluated for their thermal and photostability.

In this work, novel cellulosic fibers are extracted from Washingtonia Filifera (WF) plant using an environment friendly technique. Morphological, physico-chemical, thermal and mechanical properties are reported in this paper. Micro graphical SEM shows the presence of cells in the fiber. FTIR and XRD experimental analyzes show a cristinality index of 48.88%, and the WF fibers are found to be thermally stable until 201°C by using TGA and DTG thermo graphic analyzes with an appropriate activation energy of 72.46 kJ/mol, where Young modulus and tensile strength of strain were determined using tensile tests of single fiber at 2.17 GPa, 134 MPa and 26.55%, respectively. Mechanical properties are analyzed using a statistical method.
