Proton and 11 B magnetic resonance studies of the redistribution in the system BR 3 /BT 3 (R = C 3 H 7 , T = OCH 3 , SCH 3 and N(CH 3 ) 2 ) show that equilibria between different species BR n T 3– n ( n = 0, 1, 2, 3) occur. In general it appears that the ...

We have measured the coefficient of viscosityBat 25 °C of HCl, LiCl, NaCl, KCl, RbCl, KI, and KBr in the mixtures of aqueous organic solvents containing from 10 to 40%tert-butyl alcohol by weight (X), the concentration of electrolyte varying from 0.1 to 0.3 M.Plots ofB = f...
A deterministic model based upon the impedance signal was performed; lithium intercalation inside the composite cathode is normalized and included in the faradaic current. Conservation of charge is considered for the cathodic process by a balance of the charge鈥揹ischarge natural process on the ...

Finally, we consider continuous models, and more specifically a class of differential systems based on power-Iaws, known as S-systems. Within this framework, we present an iterative algorithm that finds positive equilibria of any dynamical system, giving at the same time a local power-Iaw ...

In part I (this Bulletin 80 (1971) 91-105) the binary systems As-Fe, As-Co and As-Ni were considered. The ternary systems As-Fe-Co and As-Co-Ni, as obtainable by thermal synthesis at 700° or by precipitation with AsH 3 , are now studied. The composition range covered is MeAs ...
