  1. Material chemistry Dr. Othman Al Hamouz Assistant Professor Organic and polymer chemistry

  2. Research Interests • Natural Modified Adsorbents Produced From Algae. • Novel Hybrid Inorganic-organic Coatings For Mild Steal Protection. • Novel Hybrid Polycarbonates.

  3. Natural Modified Adsorbents Produced From Algae.

  4. Natural Adsorbents Effect of algae on marine aquatic life:

  5. Polysaccharides in algae Red algae Green Algae Brown algae

  6. Metal Binding:

  7. Description of Research: • Step 1: literature review: The team will screen the types and species of algae found in the red sea and gulf coast parallel to the kingdom of Saudi Arabia. • Step 2: Sample collection and classification. The team will collect different types of algae samples from different locations at different depths and different temperatures. After collection, the samples will be cleaned and classified upon division, class, order, family and type of polysaccharides present in each.

  8. Step 3: Drying and sieving to specific particle size. The samples will be dried and the dead biomass will be grounded to specific mesh size, in order to study the effect of particle size on the adsorption capacity. • Step 4: charring the biomass of algae and activation with different activating agents. The dried samples of different types of algae will be charred and converted into char. The charred material will be activated with specific activating agents such as, potassium hydroxide, hydrogen peroxide, sulphuric acid and nitric acid.

  9. Step 5: performance of the developed material under different environments. The material obtained from step3 & step 4 will be tested as adsorbents under various conditions such as: • pH. • Temperature. • Contact time. • Dosage of biomass. • Initial Metal concentration. • Desorption and Regeneration of material. • Step 6: Testing on real samples. After testing under controlled optimum conditions the material will be tested and evaluated for their efficiency in removing heavy metals from real samples of water and waste water.

  10. Novel hybrid coatings for mild steal protection.

  11. Effect of corrosion by salt water

  12. Purpose of coating:

  13. Synthesis of novel coatings:

  14. Structural and mechanical properties of the new coatings will be investigated using various techniques: • Spectroscopic (FTIR, NMR, etc..) • Mechanical testing (hardness, scratch resistance, appraising resistance, tensile, etc..) techniques. • Thermal Analysis using Differential Scanning Calorimetry (DSC) and Thermal Gravimetric Analysis (TGA). Surface characterization of the new coatings will be carried out using: • Scanning Electron Microscopy (SEM). • Atomic Force Microscopy (AFM) and X-ray Photoelectron Spectroscopy (XPS) techniques. • Salt Spray and industrial field testing will be carried out for coating formulations with promising barrier and anticorrosive properties over mild steel substrate.

  15. Novel Hybrid Polycarbonates

  16. Uses And Applications:

  17. Properties: • Their importance came from their outstanding mechanical properties, optical clarity, exceptional compact resistance, dimensional stability, toughness and chemical stability. • The properties of polycarbonates can be controlled by varying their chemical structure, molecular mass and crystallinity. These properties enable them to enter a wide range of applications

  18. Description of Research Step1: condensation, crosslinking

  19. Step 2:transesterification

  20. The synthesized hybrid polycarbonates will be characterized using different techniques: • Spectroscopic (FTIR, NMR, etc..) • Mechanical testing (hardness, scratch resistance, appraising resistance, tensile, etc..) Techniques. • Thermal analysis using differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). • BET (Brunauer–Emmett–Teller): measuring surface area, pore size, …etc. • Atomic Force Microscopy (AFM) and X-ray Photoelectron Spectroscopy (XPS) techniques. The synthesized material will be screened for potential application in: • Protective coating. • Gas capture.
