Ternary phase equilibrium data for ethanol-water-1-hexanoic acid and 1-nonanoic were experimentally obtained with a view to evaluate the possibility of separation ethanol from aqueous solutions by distributing each between water phases. The mutual solubility curves, tie lines plait points constructed experimental results. Distribution coefficients factors computed these systems. Hand’s method w...

This work presents an investigation on phase equilibria in partially miscible systems comprised of water, esters, and alkanols. Experimental liquid–liquid (LLE) were determined for ternaries water+H2u–1Cu–1CO2CvH2v+1+CwH2w+1(OH) (u = 3,4; v 2,3; w 1–4) at 298.15 K the four corresponding water+ester binaries, temperature interval T [283–328] K. The results reveal a complex behavior ternary LLE. ...

Realistic equations of state valid in the whole state space of a multi-component mixture should satisfy at least three important constraints: (i) The Gibbs phase rule holds. (ii) At low densities, one can deduce a virial equation of state with the correct multicomponent structure. (iii) Close to critical points, plait points, and consolute points, the correct universality and scaling behavior i...

Even in the absence of surfactants, polymers, or particles, spontaneous emulsions produced by dilution with water can be stable over days. This “Ouzo effect” used industry is obtained rapid from an identified “pre-Ouzo” domain composition where weak aggregates are present: nanometer-sized clusters covered a surface layer enriched hydrotrope such as ethanol. In these systems, Ostwald ripening no...

The TRAPP (transport protein particle) complexes are tethering complexes that have an important role at the different steps of vesicle transport. Recently, the crystal structures of the TRAPP subunits SEDL and BET3 have been determined, and we present here the 1.7 Angstroms crystal structure of human TPC6, a third TRAPP subunit. The protein adopts an alpha/beta-plait topology and forms a dimer....

Indian Dermatology Online Journal | Volume 9 | Issue 1 | January‐February 2018 71 Sir, Hairs are an important contributor to the beauty of a person and have often been subjected to harsh chemical treatments in the hope of a cosmetically better appearance. However, considering the effect that these chemicals can have on hair, we need to be careful regarding what we are subjecting our hair to. An...
