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...

Concentrated sulfuric acid (SA) and nonionic surfactant (C12H25(OCH2CH2)10OH, C12E10) form lyotropic liquid crystalline (LLC) mesophases in a broad range of SA concentrations; the SA/C12E10 mole ratio may vary from 2 to 11 in the LLC mesophases in the presence of a small amount of water. The mesophase is hexagonal at low SA concentration and cubic at higher concentrations. Three different compo...

The supplementary effects of an emulsifier mixture (polyoxyethylene (20) sorbitan monolaurate and distilled monoglycerides) were investigated on feed utilization, growth performance, immunity olive flounder, Paralichthys olivaceus, replacing fish oil with beef tallow. A containing diet was considered as positive control (PC) a tallow instead negative (TW). Two other diets (EM01 EM02) prepared b...

Water-based lubrication, due to the poor film-forming ability of water, faces challenges in achieving effective lubrication for titanium alloys. This study systematically investigates frictional performance phosphorus-based extreme pressure (EP) additives and self-emulsifying esters (SEE) on surface alloy (TB6) under different pressures temperatures. The core lubricant consists SEE with nonylph...
