Micellization of sodium dodecyl sulfate and polyoxyethylene dodecyl ethers in solution
The effect of polyoxyethylene type nonionic surfactants (C12En n=3, 4, 5, 6, 7 and 8) on the aqueous solution of sodium dodecyl sulfate (SDS) in absence and presence of NaCl was examined using small-angle neutron scattering (SANS), dynamic light scattering (DLS), and viscosity measurements. Upon addition of C12En, micellar size of SDS was found to increase significantly, and such micellar elong...
متن کاملCutaneous Evaporation in Heat-stressed Spotted Sandgrouse’
Many species of desert birds are relatively small (< 500 g), diurnally active ground dwellers that are naturally exposed to high ambient temperatures (T,) and low relative humidities (RH). Sandgrouse (Pteroclididae), being small birds (weighing between 200 and 400 g) having a relatively high standard metabolic rate (SMR), would have to possess an effective mechanism for dissipating heat. Spotte...

sisting of a short length of 8 mm. diam. Visking tubing knotted to form a bag, the open end being secured to a piece of glass tubing by a close-fitting rubber stopper fitted to a test tube with a side arm. The bag, after being washed with distilled water, was equilibrated with a drop of the sample solution; this drop was discarded before evacuating the tube and introducing the rest of the sampl...
