At present, the focus of our research is on melt textured materials with top seeded melt growth, thick films on ceramic substrates and its applications (fault current limiters) and on low cost preparation of high critical current coated conductors (spray pyrolysis, screen-printing and doctor blade techniques). Our research has involved a large spectrum of experimental techniques and materials preparation approaches. This includes structural studies with X-ray diffraction, DTA/TGA technique, optical and SEM microscopes, AC susceptibility and transport critical current density. We have also developed a large number of national scientific collaborations mainly with teams from Faculty of Engineering, Mansoura University, and Department of Chemistry, Faculty of Science, Mansoura University. We have also developed an international collaboration with superconductor group at University of Birmingham, School of Metallurgy and Materials, U.K. and with Department of Low Temperature, Institute of Physics, Academy of Sciences of the Czech Republic, Prague. The superconductor group was founded in 2003 as a subgroup from the Group of Electrical and Magnetic Properties of Electronic Materials and since then we have been working on different aspects of high temperature superconductors. Originally concentrating on several materials preparation procedures, sol-gel and solid state reaction techniques, are used in producing precursors which utilized in fabricating thick films and bulk materials. The relationship between materials processing, microstructural and superconducting properties is one of our major concerns in view of developing practical applications based on the investigated materials.

Research on optical, colour and physical properties of fibres in our laboratory in Mansoura has been started at 1972. Since 1972 research is carried out with a growing rate from year to another. The studies of the group are in two main branches which are:
1- Interferometric measurements
Interferometry is a very useful tool in fibre science. It provides a quantitative information about mean refractive indices, birefringence and index profile of textile, synthetic polymer and optical waveguide fibres. Our study concerns on studying the optical and structural properties of fibres having regular and irregular cross-sectional shapes, homogeneous and heterogeneous structure, natural and man-made fibres. Also, the optical properties and their relations with the chemical, mechanical and thermal treatments have been studied to give opto-mechanical and opto-thermal properties and their relations with the structural properties of fibres.
* Many modifications in the methods of calculation of the refractive indices and birefringence of fibres are carried out by our group. Some of these modifications are:
1- Considering area under the interference fringe shift instead of the distance under the interference fringe shift. Also considering the cross-sectional area instead of the thickness of the fibre.
2- Measuring the refractive indices of the fibres with out the necessity of measuring the refractive index of the immersion liquid. This can be done by using two fibres, one of them is standard fibre with known refractive index and dispersion properties.
3- Using the variable wavelength interferometric technique taking the area under the fringe shift and cross-sectional area into consideration.
4- Driving Mathematical expressions to measure the refractive index profile of fibres considering the refraction of incident light beam inside the fibre.
5- Using optical Fourier transform technique OFT with the variable wavelength interferometric technique to determine accurately the positions of the coincidence and anti-coincidence cases of the VAWI technique.
2- Colour measurements
Colour matching is one of the most important tasks in colorant industries. A computer program was prepared on the basis of spectral reflectance of dyed textile material to give an accurate estimation for the pattern to be matched (1975). A study of ; fastness of dyes to light and the effect of finishing treatment on colorimetric properties of dyed fibres is carried out (1976-1977). A comparison study between the colour-difference formulae with respect to the CIE color-difference formula proposed by Wygzecki in 1964 have been carried out using experimental data of seven direct dyestuffs (1986).
* The model to predict of the colour absorbing – scattering substrates taking into account the effect of optical anisotropy of fibres and definite values of the indices of refraction in the visible spectral range is suggested by the group of Hamza (1992). Also, the prediction of absorbance from reflectance for an absorbing scattering fabric is carried out in (1997).

Major field of research is preparing new polymeric materials and polymer complexes by using electropolymerization technique. We are focusing on special types of polymers, which can be graphitized after heat treatment, hopping to prepare types of carbon fibers as well as composite materials. We are interested in polyacrylonitrile ,polyacrylamid ,polyacrylicacid , polypropenol and their polmer complexes with different metals.
Physical properties of prepared samples are infesized using A.C Conductivity and dielectric measurements under different temperature and wide range of frequencies ranged from 2x10-3 Hz to 105 Hz using lock in amplifier technique. DC measurments are performed as well as UV , IR and X-ray spectroscopical investigations. Thermal analysis and elemental chemical analysis are also taken into our considerations.
