Result of the tribological tests, carried out using ball-on-disk tribo-pair in dry sliding, showed a considerable improvement in coefficient of friction up to ∼55% and the wear rate ∼35% in CaF2/ZTA composite as compared to pure ZTA composite fabricated via chemical processing route followed by hot pressing. In the later stage, a similar CaF2/ZTA ceramic composite was fabricated by traditional physical mixing process of commercial CaF2 and ZTA powders followed by hot pressing using the same parameters and the tribological performances were compared. The specimen fabricated via chemical route possessed better responses in terms of tribo-mechanical behaviors as compared to the specimen fabricated via traditional mixing. Various phases of the composites were examined by X-ray diffraction. Elemental distribution and the worn surface were characterized by energy dispersive X-ray analysis and field emission scanning electron microscopy, respectively.

The effect of treatment temperature on the micro-arc oxidation ceramic layer structure and corrosion resistance was studied. The formation mechanism of Mg-Al LDH film and corrosion mechanism of the film layer were discussed. The results show that the sealing essence of Mg-Al LDH is that the Mg2+ obtained by dissolving the MgO component of the MAO film layer is combined with OH– in the hydrothermal solution to form a layered Mg(OH)2, the formation of LDH tends to be inside the pores. In the lower temperature range, the temperature increase is conducive to the increase and thickening of the LDH layer and the film layer is dense and corrosion resistant. In the higher temperature range, the increase in temperature is conducive to the increase in the size of the LDH layer. The layer is loose and coarse, and the corrosion resistance is reduced. The composite film is the densest at 90oC, and its insulation and corrosion resistance are better than the composite film obtained at other temperatures, the MAO film and the substrate.

The primary aim is to establish a facile solution combustion reaction to produce YVO4 nanopowder with lower band gap using vanadium pentoxide (V2O5.nH2O) gel as precursor and then investigation of its photocatalytic activity against anionic and cationic dyes in presence of visible light. The powder X-ray diffraction (PXRD) analysis reveals the formation of pure YVO4 with tetragonal phase having crystallite size ∼30.95 nm. Scanning electron micrograph (SEM) exhibits highly porous nature of the product. Breauner-Emmet-Teller (BET) surface area analysis of YVO4 nanopowder shows a relatively large specific surface area of ∼46.57 m2.g–1. Transmission electron microscopy (TEM) exhibits uniform particle size distribution with average particle sizes varying in the range of 20-100 nm. The band gap of 2.16 eV is calculated using the ultraviolet diffuse reflectance spectrum (UV-DRS) of YVO4. The photoluminescence spectrum of YVO4 nanopowder shows emission peak at 572.2 nm. The photocatalytic degradation of methylene blue (MB) using YVO4 as photocatalyst shows 92% decolorization in presence of visible radiation. Photocatalytic activity has also been extended to investigate the degradation of amaranth dye and rhodamine-B (Rh-B) under visible light irradiation which reveals 80% degradation of amaranth dye but Rh-B shows only 65% decolorization using YVO4 nanopowder. Hence YVO4 nanopowder shows good photocatalytic activity for MB and amaranth dye compared to Rh-B.

The optimum synthesis conditions were as follows: Ce3+ concentration 0.06 mol%, Lu3+ concentration 0.5 mol%, Sm3+ concentration 0.02 mol%, calcination temperature 1300oC, insulation time 1.5 h. The effects of introduction of Lu3+ on the crystal structure, temperature stability and luminescence properties of YAG:Ce3+,Sm3+ were studied. The results showed that due to the introduction of Lu3+ ions, the matrix lattice slightly changed (belonging to the cubic crystal system), the emission peak was blue shifted, temperature stability improved and decay reduced, which plays an important role in improving the lifetime of white LEDs.

The membrane was obtained by sintering the clay disc at 850oC for 5 h. The raw material and the membrane were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), thermo-gravimetric analysis (TGA), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), porosity, and pure water permeability. The XRF and XRD analysis of the clay confirmed the presence of components required for ceramic membrane preparation. Average pore size, apparent porosity, and pure water permeability of the membrane was obtained as 5.88 µm, 24.30%, and 0.9865 l.m–2.h–1.kPa–1, respectively. Chemical stability was carried out by keeping the membrane in HCl (pH=1) and NaOH (pH=14) solutions for one week. The prepared membrane showed excellent chemical resistance in both the media. The overall fabrication cost of the membrane was estimated as 301 $/m2. These results indicate that the clay used in this work could serve as an alternative raw material to kaolin based ceramic microfiltration membranes for cheaper use in different chemical and biochemical processes.

Energy dispersive spectroscopy was employed to confirm the weight percentages of elements present in the composites. Transmission electron microscopic analysis was performed to observe morphological changes in the composites. X-ray diffraction analysis was carried out to confirm the phases of developed reinforcement and composites. A universal testing machine was employed for the observation of mechanical properties, viz. flexural strength, Young’s modulus and diametral compressive strength, and it was found that the mechanical strength improved by 50-55% in the case of 10 vol% SiO2 coated Al-ABOw composite. The effect of SiO2 coating on the hardness of fabricated composite was also evaluated and the maximum microhardness value was observed to be 46.2 HV in 10 vol% SiO2 coated composite.

Ti, M n, Co and Ni metal particles introduced into the MgAl2O4 system can produce a variety of colours from white, grayish black, blue to turquoise blue. Mn, Co and Ni metal particles added into MgAl2O4 system can extend their light absorption to visible light range, while the Ti metal particles clad into the system did not improve significantly. Co metal particles appended into the MgAl2O4 system can cause fluorescence quenching of emission peak at 395 nm and enhancement of emission peak at 405 nm, while the Ti and Mn metal particles infused into the system can bring the enhancement of visible emission peak at 425 nm. The fluorescence quenching of the peak at 395 nm can be ascribed to the wavelength of Co metal particles matching the surface plasmon absorbance band of MgAl2O4:M phosphor. A reduction in emission intensity at 425 nm can be assigned to electron transfer from the conduction band (CB) of MgAl2O4 to the CB of metal particles causing non-radiative decay.
