This book gives the reader an introduction to the field of surfactants in solution as well as polymers in solution. Starting with an introduction to surfactants the book then discusses their environmental and health aspects. Chapter 3 looks at fundamental forces in surface and colloid chemistry. ...
Surface chemistry Each type of synthetic, natural, or composite scaffold gives rise to a set of distinct surface chemical characteristics governed by the material chemistry and its physical form (such as crystallinity, charge, and topology). Although numerous efforts have been made to tailor the sca...
Surface activation can be defined similar to the other methods used to alter the chemistry of surface introducing chemical groups or charges on the surface or physical changes created on the surface through etching, removing impurities by ablation, roughening, wavy shapes, and voids formation. ...
In surfactant-polymer (SP) and alkaline-surfactant-polymer (ASP) flooding, the water is first treated to remove: impurities, suspended particles, and organic and inorganic particles. Then a certain amount of surfactants and polymers are added to the surfactant slug and polymer drive, respectively2...
Surface Active Polymers Can be Designed in Different Ways Polymers May Have a Hydrophilic Backbone and Hydrophobic Side Chains Polymers May Have a Hydrophobic Backbone and Hydrophilic Side Chains Polymers May Consist of Alternating Hydrophilic and Hydrophobic Blocks Polymeric Surfactants Have Attractive Proper...
Plasma treatment is recognized as a suitable technology to improve germination efficiency of numerous seeds. In this work Quinoa seeds have been subjected to air plasma treatments both at atmospheric and low pressure and improvements found in germination
In the present work, the self-assembling of some synthesized thiol surfactants namely (6-(3-amino phenoxy) hexane-1-thiol, 8-(3-amino phenoxy) octane-1-thiol, 10-(3-amino phenoxy) decane-1-thiol, 12-(3-amino phenoxy) dodecane-1-thiol, and their polymers on silver nanoparticles was inv...
Syntheses of mesoporous oxides rely on the use of templates. Porosity is typically generated by sacrificial templates that fill the pores during synthesis and are removed afterward.30, 31, 32 A typical example is the use of soft templates such as organic surfactants or block copolymers that co-...
more water to pass. Furthermore, the simulations were run using the class II potential developed by Sun, Rigby, and others within an explicit-atom (EA) model. This force field is universally applicable to the atomistic simulation of polymers, inorganic small molecules, and common organic ...
This attractive technique has been used since 1970 to quantify the specific interactions and the surface properties and glass transition of polymers, copolymers, their blends and polymer films [5,6,7,8,9,10,11,12,13,14,15,16,17,18]. It was also used to determine the surface energy, the...
