Studies on metallochromic indicators—I Pyrocatecholphthalein as metallochromic indicator

Talanta, 1967
Pyrocatecholphthalein has been used as a metallochromic indicator for the direct complexometric titrations of a number of metal ions with EDTA, both in acidic and in alkaline medium. Th, Bi(III), Ba, Sr, Ca, Mg, Mn(II), Pb(II), Cu(II), Cd, Ni, Co(II) and Zn have been successfully titrated.

A study of toughness indices

Magazine of Concrete Research, 1985
Synopsis The paper reviews various methods of evaluating the toughness of fibre-reinforced concrete materials by means of toughness indices and discusses in detail the use of various multiples of jirst-crack defection to define toughness indices. A new toughness index is proposed, based on the load–deflection curves obtained up to twice the defection
