The purpose of this study was to achieve this objective by using design of experiment to perform optimization of a ceramic membrane made from clays and rice husk. Two kaolinite clays, namely MY3 and KG, were used with rice husk to manufacture ceramic membranes. After sintering, the obtained products underwent characterizations such as flexural strength, open porosity, permeability, hydraulic diameter, XRD analysis and microscopy image analysis. The effects of each component on membrane properties were modelled with linear models. The results showed significant interactions between constituents and between membrane properties (porosity with resistance, permeability with porosity and hydraulic diameter). The optimal mixture consisted of 83% MY3, 15% KG and 2% rice husk which presented 8.0 MPa flexural strength, 30% porosity, 675 L.h–1.m–2.bar–1 permeability and 2.6 µm hydraulic diameter. Filtration of slaughterhouse wastewater showed a reduction of 97% chemical oxygen demand, 99% turbidity, 80% total dissolved solid, electrical conductivity and salinity. 84% pseudomonas and 75% vibrio cholerae were also eliminated.

Corrosion resistance of binary and ternary LDH coatings was studied by comparison. Structures of the two films were characterized using XRD, FTIR, SEM and EDS, and the corrosion resistance of the films was evaluated by polarization curve, EIS, and hydrogen evolution rate during immersion in 3.5 wt% NaCl solution. Results showed that Mg-Al LDH film was tightly bonded to the substrate and had a large number of nanosheets growing perpendicular to the substrate, while Mg-Al-Co LDH film was thinner with a smaller size and fewer nanosheets. Electrochemical test results showed that the polarization resistance of Mg-Al and Mg-Al-Co LDH films was two orders of magnitude higher than that of the substrate. Hydrogen precipitation experiments showed that corrosion resistance of both the films was improved compared to the substrate, and the films played a protective role for the substrate, among which the corrosion resistance of the Mg-Al LDH layer was better than that of the Mg-Al-Co LDH layer.

The effect of different rare-earth oxides, viz. CeO2, La2O3 and Y2O3 at 2 wt% level on the properties of different spinel batches was studied. Y2O3 was found to favour densification in both the spinel batches while CeO2 and La2O3 were found to favour densification only in the MgO-rich spinel compositions. Phase analysis revealed that Y2O3 containing Al2O3-rich spinel has a secondary phase with similar crystal structure to spinel (both cubic) and improved densification, while in the MgO-rich condition, Y2O3 remained as secondary phase and assisted in densification. CeO2 and La2O3 in Al2O3-rich samples formed secondary phases with different crystal structures and resulted in reduced densification. While in MgO-rich condition, CeO2 (cubic) did not react with Al2O3 and La2O3 formed a secondary phase with similar crystal structure as that of spinel and therefore assisted in densification. Addition of rare-earth oxides led to improvement in strength of MgO-rich spinels and maximum improvement in strength was observed with the addition of yttria.

Conductance, capacitance and impedance spectroscopy characterization of ZnCo2O4 ceramics sample were analyzed in 3 kHz-1.5 MHz frequency range and 300-500 K temperature range. Nyquist diagrams of impedance and the equivalent circuit were studied for ZnCo2O4 ceramics in the temperature range of 300-500 K. Cole-Cole curves of the impedance data were found to show a semicircular arc in both low and high temperature areas, which is expressed by the equivalent electrical circuit Rs (RgC g)(RgbQCgb ). Relaxation behavior was identified to be of non-Debye type. The Cole-Cole curve showed the negative temperature coefficient of resistance type behavior. Values of the activation energy corresponding to relaxation processes were found as 0.054 eV below 360 K and 0.561 eV above 360 K.

Structural, topographical and optical properties of MNZO thin films were studied in the light of XRD spectra, Raman spectroscopy, SEM, AFM, UV-visible spectroscopy and photoluminescence spectroscopy. XRD study revealed that all annealed ZnO thin films have hexagonal wurtzite structure with (002) preferred orientation along c-axis. Hexagonal wurtzite structure for all films has been confirmed by Raman spectra which show optical phonon modes. Grain size, micropores and RMS surface roughness showed an increasing trend with the rise in annealing temperature as revealed by SEM and AFM images. The experimental data of absorption coefficient was analysed in the light of hydrogenic excitonic model to estimate excitonic binding energy (R) and other optical parameters of the prepared thin films. The excitonic binding energy decreased from 71.55 to 49.2 meV on increasing annealing temperature from 200° to 500°C. Peaks corresponding to UV, violet, green, yellow and orange were clearly observed in photoluminescence spectra for all annealed thin films. The ultraviolet peak shifted towards lower wavelength (blue-shifted) as the annealing temperature was increased. All the peaks in visible region were attributed to transition between complex intrinsic and extrinsic defects. Such films can be a potential candidate for efficient lasers and LEDs and for variety of optoelectronic device applications.
