Abstract Quantum dot (QD) growth on high (c 3v ) symmetry GaAs{111}
surfaces holds promise for efficient entangled photon sources. Unfortunately,
homoepitaxy GaAs{111} surfaces suffers from surface roughness/defects
and InAs deposition does not natively support Stranski–Krastanov (SK) QD
growth. Surfactants have been identified as effective tools to alter the epi...

Bioremediation can be defined as any process that uses microorganisms or their enzymes to remove and or neutralize contaminants within the environment (i.e., within soil and water) to their original condition. Bioremediation can be employed to remediate specific types of contaminants such as; petroleum hydrocarbons, polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyl’s (PCB), chlor...

this study examines the effects of change in the concentrations of monovalent and divalent ions in the polymer-contained surfactant solution on the macroscopic behavior of viscous-modified surfactant waterflooding in heavy oil reservoirs. salts that are used in this set of floods were sodium chloride, magnesium chloride, and calcium chloride. the results indicate that four different ranges of s...

Types A and B Niemann-Pick disease (NPD) are lipid storage disorders caused by the deficient activity of acid sphingomyelinase (ASM). In humans, NPD is associated with the dysfunction of numerous organs including the lung. Gene targeting of the ASM gene in transgenic mice produced an animal model with features typical of NPD, including pulmonary inflammation. To assess mechanisms by which ASM p...

The mechanisms driving the surfactant-enhanced spreading of droplets on the surface of solid substrates, and particularly those underlying the superspreading behaviour sometimes observed, are investigated theoretically. Lubrication theory for the droplet motion, together with advection–diffusion equations and chemical kinetic fluxes for the surfactant transport, leads to coupled evolution equat...

Applied Rheology Volume 21 · Issue 5 Abstract: The rheological behavior of the olive oil-in-water emulsions has been studied by varying the oil to water ratio as well as the surfactant concentration. The viscoelastic property of the olive oil emulsions was investigated with a cone-and-plate system, using a Bohlin C-VOR Rheometer. The obtained results indicated that the emulsions with greater oi...
