  • Synthesis of metal nanoparticles and their use in RO/NF cellulose acetate membranes and evaluation of the membrane resistance to microorganisms

The aim of this project has been to synthesize different metal nanoparticles (MNPs) from silver, copper,
and Zinc. Experimental conditions will be changed in order to have MNPs with different sizes
and size distributions.The resulting MNPs will be characterized by UV-Visible Spectroscopy, Fourier Transform Infra-
Red Spectroscopy, Scanning Electron Microscopy, Atomic Force Microscopy, Dynamic Light
Scattering and X-Ray Diffraction.
The antibacterial activity of these MNPs will be studied against common microorganisms found
in contaminated water and those degrading cellulose acetate polymers

  • Monitoring of harmful chemicals and harmful microorganisms in Cereal Grains Sold in Hail City

The research is an attempt to the identification of suitability of some cereals sold in Hail for human consumption through conducting chemical and microbial analyses of some cereals samples. The study aimed to monitor the heavy metals, organochlorine pesticide residues as well as pathogenic microorganism in cereal grains that are sold and milled to fine flour and used by many people in Hail city during the period 2015- 2016, as no similar study has been practiced in the province. The study includes several cereal grains such as wheat, barley, corn, rice and sorghum.

  • Geochemical and bacteriological study of the soil in Hail industrial zone, Saudi Arabia

The study aims to analyze the concentration of heavy metals and bacteria flora in the soil of the industrial zone in Hail city, and the correlation of their numbers and type as no similar studies. Soil samples from various depths (levels) of the soil, were collected from different localities from the industrial zone.  Heavy metals (Fe, Mn, Cd, Zn, Cu and Pb) and major element (Na, Ca, Mg and K) were determined using Flame Atomic Absorption spectrometry (FAAS). Bacteria were isolated from soil samples, purified, counted and identified using morphological and biochemical methods using Api identification kits

  • Evaluation of Antimicrobial Effects of Selected Medicinal Plants and their Synergistic Effect with Antibiotic and Non-antibiotic Drugs in Hail area

The study aims to evaluate the antibacterial effects of selected medicinal plant extracts and their synergistic effects with antibiotic and non-antibiotic drugs  in Hail area. The anti microbial activity of the plants extract were determined using the disc diffusion method in which the inhibitory zones was recorded in milliliters. The tested bacterial species included: bacteria: E. coli, Staphylococcus aureus and Salmonella spp.  The synergistic effect between plants and extraction of antibiotics and / or Non-antibiotic drugs were evaluated using disk diffusion method.
