Genetic Cell-Surface Modification for Optimized Foam Fractionation

Riser Design in Foam Fractionation

The growth of biotechnology has led to renewed interest in the possibility of enriching valuable bioproducts using foam fractionation. This is a separation process in which surface active molecules are separated from a solution by sparging through bubbles of gas. Adsorption of such molecules at the gas/liquid interface causes enrichment in the foam formed above the liquid pool. Previous work ha...

Surface modification for titanium implants by hydroxyapatite nanocomposite

Background: Titanium (Ti) implants are commonly coated with hydroxyapatite (HA). However, HA has some disadvantages such as brittleness, low tensile strength and fracture toughness. It is desirable to combine the excellent mechanical properties of ZrO2 and the chemical inertness of Al2O3 with respect to the purpose of this project which was coating Ti implants with HA-ZrO2-Al2O3 to modify the s...

Optimized Standard Cell Generation for Static CMOS Technology

Fabrication of an integrated circuit with smaller area, besides reducing the cost of manufacturing, usually causes a reduction in the power dissipation and propagation delay. Using the static CMOS technology to fabricate a circuit that realizes a specific logic function and occupies a minimum space, it must be implemented with continuous diffusion runs. Therefore, at the design stage, an Euleri...
