The osmium isotopic composition of the Earth's primitive upper mantle
THE elevated abundances of highly siderophile elements in the Earth's mantle, relative to what would be predicted from metal–silicate equilibrium, have often been cited as evidence for the accretion to the Ear...

Thermal Investigation of Alkaline Fatty Acid Salts
Results of thermoanalytical studies concerning the behaviour of the alkali-metal salts of fatty acids are summarized. The questions of preparation, thermal history effects, mesomorphic state, thermal decomposi...

Error Analysis in Thermal Purity Determinations
We studied by simulation and experimentaly the deviations occuring at purity determinations. We propose a method for the proper choice of range for evaluation.The continuous and stepwise measuring techniques w...

Thermal Behaviour of Some Organic Compounds with Ionic Character
The thermal decomposition of Li, Na, K, Rb, Cs salts of formic, acetic, propionic and n-butyric acids have been investigated in air and inert gas atmosphere. The differences between the processes are described...
