Surfactant

Abstract: Every year, more than 11 billion pounds of unused feathers result from the poultry industry worldwide, which in effect impose a difficult disposal process to the environment. Chicken feathers are an abundant, inconvenient and troublesome waste product from the poultry industry that can be utilised as a source of keratin. In addition to keratin, feathers contain other fatty and waxy substances. An original chicken feather contains many biological organisms…

Surfactant therapy is the administration of an artificial surfactant that is placed into the baby’s lungs to help keep the air sacs open, while nitric oxide inhalation is thought to improve oxygenation in MAS after treatment with surfactant due to many infants responding well to the combination. So far, the outlook on MAS is promising being that there is no long-term…

micelle formulations include insufficient drug loading, stability, and selective uptake by targeted cells17. A common misconception is that micelles are not solid structures or necessarily circular. Micelles exist in an active equilibrium with other surfactant molecules where monomers switch between adsorbing at the air-liquid interface, moving freely throughout the bulk solution, and aggregating to form micelles17. Below the CMC, monomers remain free in solution and adsorbing at the air-liquid…

Normal function of Respiratory System The function of the respiratory system is to provide the entire body with oxygen while simultaneously getting rid carbon dioxide through the process of ventilation (Shoopman, 2015, p.513). The respiratory system is split into two different sections: the upper respiratory tract and the lower respiratory tract (Appendix A). As air enters the body, it first passes through the upper respiratory tract, which consists in the order of the mouth and or nose,…

Problem : April 22 of 2010, approximately 206 million gallons of oil was spilt in the Gulf of Mexico. The Mother Nature Network stated, “Gulf Oil Spill is the officially the largest oil spill in the world history”, (“Mother Nature Network”, Laura Moss). The Gulf Oil Spill started when oil went miles below the surface of the Gulf of Mexico, and it exploded. It caused BP’s Deepwater Horizon rig that it killed 11 people. The oil spread for more than 85 days and oiled 572 miles. Along the way,…

The United states has one of the largest demand for energy in all forms. One common way to get the energy we need is through hydraulic fracking, but it has become more controversial as we know more about it. This paper will discuss what Hydraulic fracking is, what has been the recent controversy around it, and finally what effects the injection of wastewater has on the ground water and seismic geology of the region. Generally speaking, hydraulic fracking is the process of drilling a hole and…

1990). Lipases and cellulases in certain detergents remove dirt/ cattle manure from domestic animals (Abo et al., 1990). Lipases are also used in degreasing and water reconditioning in combination with oxido-reductases that require lesser amount of surfactants and work at low temperatures (Novak et al.,…

thin film hydration method with different concentration of surfactant (Span80, Tween80, and Sodium Deoxycholate) and soya lecithin and characterized for various parameters including Vesicles Size, Morphology, Entrapment Efficiency, Drug Loading Capacity, Turbidity measurement and Stability Evaluation. Optimization of the formulations was done by selecting three process variables: a) concentration of soya lecithin b) concentration of surfactants (Sodium deoxycholate, Tween 80 and span80) and c)…

the long run, however, they could harm your face and cause irritation to your eyes since most of them are loaded with chemicals and toxic ingredients. Makeup wipes are no better since they contain the same active ingredients as cleansers -- surfactants to dissolve makeup, and emulsifiers and solubilisers to lift oil and dead skin. If you aren't rinsing with…

enhanced stream and more rapid extinguish and restraint flames, nonetheless narrow fire security. Such synthetic foam is known as aqueous film forming foams. Aqueous film forming foams are water based and commonly comprise of hydrocarbon based surfactant such as sodium alkyl sulfate, and fluorosurfactant, such as fluorotelomers, perfluorooctanoic acid, or perfluorooctanesulfonic acid (Klaus, 2013). All having the capability to extend fully over the surface of hydrocarbon based liquids.…
