Surfactant

aa’ in the region when the SDS surfactant starts to appear and populate the surface of the droplet. The deviation of the Köhler term in the evaporation model as result of the presence of SDS inclusions is clearly seen in the insert. Parameterization of the Köhler term to account for such influence for e.g., solute in mixtures for microdroplet activation have been reported in [5–7] with different approaches. Here we try to model the effect of the soluble SDS surfactant inclusions growing…

Results and Discussion This part shows all the data gathered by the students after certain experimentations were done. These tests will be utilized as a basis in determining which body gel between the two brands specifically Baylis and Harding Royale Bouquet and Silka, is more effective and efficient product to use than the other one. Experimentation 1: Determining which Body Gel has smoother and more fragrant effect A healthy lifestyle and products for skincare routine reflect on one’s skin.…

born about six weeks before their due dates. Respiratory Distress Syndrome is fairly common in premature infants because their lungs are unable to make enough surfactant. Surfactant is a liquid that coats the inside of the lungs. This liquid helps the lungs open up so that the child is able to breathe once they are born. Without this surfactant, the lungs collapse and the infant has to work extremely hard to breathe. The child is then unable to breathe enough oxygen to support their organs. This…

Distress in Newborn: It is important to understand that illness in the newborns often manifest as respiratory distress. All infants in respiratory distress should be stabilized as quickly as possible, obtaining radiographic/labs/microbiology tests and results must not delay treatment. Most common newborn diseases that present with respiratory distress are following: Meconium Aspiration Syndrome: MAS consists of delivery through meconium stained amniotic fluid with respiratory distress. Neonates…

NANOCARRIERS AS PROMISING NOVEL SYSTEMS FOR CONTROLLED DELIVERY OF DICLOFENAC SODIUM [N.B: Authors' details blinded by Pro Journals for Review] ABSTRACT The formulation and evaluation of Diclofenac sodium from liposomes, niosomes and nanoemulsion are analyzed. The release profiles of Diclofenac sodium were almost similar in all the formulations. It is found that 85% of Diclofenac sodium diffused out from the colloidal systems within 8hrs and practically all the drug was released within…

is called the pulmonary surfactant and it is made of a complex mixture of phospholipids, neutral lipids, and proteins. The disaturated phospholipids are the active component of the pulmonary surfactant. The disaturated phospholipids have tails that are hydrophobic and are tightly packed together which allow the reduction in surface tension. The reduction aids in inspiration and the surfactant also aids in expiration. When the gas holding structures deflate, the surfactant prevents the structures…

6.3. A. Microemulsions (135-143) Microemulsions are clear, stable, isotropic mixtures of oil, water, and surfactant, frequently in combination with a cosurfactant 135-137. Microemulsions have several advantages such as enhanced drug solubility, good thermodynamic stability, and higher transdermal permeability over conventional formulations 138,139. Many studies reported the use of microemulsions as topical drug delivery vehicles showed their ability to improve transdermal and dermal delivery…

ABSTRACT Elaeis guineensis is a species of palm generally called African oil palm, and it can reach the height of 20 m or more at maturity. The oil palm is major importance in Africa as a multi-purpose tree where it supplies medicines, foods and many other products to the local population. Elaeis guineensis is rapidly becoming one of the world's most planted plants, being grown especially for its oil-bearing seeds and fruits. Usually 23 kg is the average weight of each bunch but a bunch may up…

Methane hydrate has been proved to form faster if increasing the water-gas interface area by agitation of the water (Narita et al., 1996). However, with the appearance of surfactant, the formation rates of gas hydrates can also be increased multiple orders of magnitude (KARAASLAN et al., 2000) even in unstirred system (Zhong et al., 2000). This invention saved the energy costs from stirring hydrate slurry and separation of…

4A.3 Results and discussion 4A.3.1 Selection of Excipients Drug loaded Solid Lipid Nanoparticles(D-SLN)were successfully formulated using two different lipidsand surfactants and physicochemical parameters of the same have been assessed. Tamoxifen citrate is proven adjuvant therapy of choice for postmenopausal women, primary therapy for breast cancer in elderly women as well as preventive therapy for most vulnerable women. The extensive administration of Tamoxifen citrate daily for a period of…
