Journal ArticleDOI
TL;DR: The mixed oxides of iron and manganese which are stable at high temperatures in the air crystallize with the spinel structure and can be expressed by the formula Fe3−xMnxO4+δ as discussed by the authors.

Journal ArticleDOI
TL;DR: In this article, the authors applied the extraction chromatography method to the separation of Es(III) and Fm(III), and the distribution coefficients of the separation factors were studied as a function of temperature with HDEHP adsorbed on Celite.


Journal ArticleDOI
TL;DR: In this paper, the spectral and thermal properties of rhodium(II) acetate adducts were investigated using thermogravimetric analysis and differential scanning calorimetry.

Journal ArticleDOI
TL;DR: The reactions of several dihalides of manganese, iron, cobalt, nickel, copper, and cadmium with tetrahydrofuran and 1,2-dimethoxyethane have been investigated as mentioned in this paper.

Journal ArticleDOI
TL;DR: In this article, a tentative phase diagram is derived which explains all the anomalies in the thermal behaviour observed previously, and a trigonal superstructure was found with A = 2aNiAs, C = 3cNiAs; the vacancy ordering in Cr7S8 is the same as in 3c-Fe7Se8.
