New generation of dispersants by grafting lignin or xylan
(2017)Synthetic dispersants are commonly used in the stabilization of various colloidal suspensions. However, their non-biodegradable and toxic natures hamper their industrial use. The use of natural polymers as dispersants for ... -
A novel approach to reaction modeling for photocatalytic oxidation processes
(2014)Volatile organic compounds (VOCs) are one of the major concerns for indoor air quality. A new method for treating VOCs in the air is through an advance oxidation process (AOP) known as photocatalytic oxidation (PCO). ... -
A numerical simulation study on the interaction of particles with rough surface and soft structures in suspension systems
(2022)Particle interactions in complex colloidal systems are essential in a variety of traditional and emerging industrial processes. This thesis applied the extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory to calculate ... -
On the motion of vertical and oblique sand jets in stagnant immiscible liquids
(2019)Sand jets and particle clouds in water and viscous fluids have been a frequent subject of intense research and are pertinent to many environmental, industrial, and engineering processes. Mixing and dispersion of sand ... -
Studies on cultivation, cell wall development, and gene analysis of marine microalgae pleurochrysis carterae and isochrysis zhanjiangensis
(2021)In last decade, the mankind has been intensively facing the climate changes in the whole world, because the demand for fuel and greenhouse gas emissions isincreasing dramatically, especially the amount of carbon dioxide. ... -
A study in lignin capability to improve strength and water absorbency of starch polymers: a potential heat-resistant fluid-loss-controller in water based drilling fluids
(2021)In the oil and gas industries, drilling deep wells has rapidly become more significant to meet the global demand. The design of drilling fluids and choosing the proper additives are very important for the drilling operation's ... -
Sulfo-functionalization of lignin and its impact on the stabilization of colloidal systems
(2021)Lignin macromolecules, derived from renewable biomass resources, have gained extensive interest during the past decade as a sustainable substitute for synthetic oil-based materials. The main goal of this dissertation was ... -
Synthesis and Electrochemical Studies of Titanium Dioxide Based Nanostructured Catalysts for Environmental Applications
(2016)Nanomaterials are playing an increasingly important role toward addressing emerging environmental challenges. Heterogeneous catalysis is the best option available for the elimination of environmentally incompatible compounds ... -
Tall oil production process and characterization
(2017)Existing kraft pulp mills have seen the necessity to branch out from traditional pulp and paper products to alternative value-added products such as bioenergy and biomaterials as a result of increasing competition in the ... -
Utilization of wood based hemicellulose pre-hydrolysate for the production of high value added platform chemicals
(2017)The immense benefits of using renewable resources are because they can reduce global warming and other environmental issues which directly affect life on earth. Forest residues serve as potential renewable resources which ...
