The diffusion of small molecules across a copolymer membrane is simulated as a site percolation problem, assuming that in copolymers consisting of A and B units, B are active sites and A are inactive sites. Molecular modeling is conducted in three steps: (i) generation of a copolymer by a ...
Their domain of existence in the pseudo-ternary phase diagram is limited compared to that observed for microemulsions with classical surfactants and located in the vicinity of the miscibility curve of the ternary solvents mixture. From dialysis equilibrium and viscosity measurements, it has been ...

The trialkyl-silyl-, -germyl- and -stannyl-phosphines R 3 MPEt 2 react with β-propiolactone via the cleavage of the alkyl-oxygen bond of the lactone, leading to the trialkylmetal β-diethylphosphinopropionates R 3 M O CO CH 2 CH 2 PEt 2 (M = Si, Ge, Sn). These reactions are...

We have studied the compounds with metal/tellurium ratio less or equal to unity in the ternary system Ni Co Te. The limits of the homogeneity range of the hexagonal (Ni, Co) 1–x Te phase have been fixed for different Ni/Co ratios. The compounds formed in the series (Ni λ Co 1–...
