A close relation between thermal data and the thermodynamic stability of intermetallic compounds is pointed out. Several series of intermediate phases formed by metals of theA and transition groups with elements of groups IB to IVB have been considered. The dependence of the thermal and thermodynamic stabilities on the atomic size, the electronic configuration, the electronegativity and the melting temperature of the component is discussed.

Order-disorder transitions were investigated in native cassava starch at intermediate moisture contents (35 to 60% wt. water), using Differential Scanning Calorimetry (DSC) and dynamic Wide Angle X-ray Diffractometry (WAXS) with a synchrotron radiation source.

A simple, one-step micro-synthesis of aromatic radioiodides which utilizes the in-situ formation of arylthallium bis (trifluoroacetate)
intermediates has been developed. Thallium(III) trifluoroacetate was used in the thallation of aryl compounds to yield the
intermediate arylthallium bis (trifluoroacetate). The latter was isolated, purified and used for radioiodination. Alternatively,
in-situ radioiodination was accomplished by the addition of radioactive aqueous NaI plus excess non-radioactive iodide to
complete the reaction. Yields of up to 81% of radiochemically pure compounds were obtained. Using the modified thallation-radioiodination
method, aromatic radiopharmaceuticals can be easily and quickly labelled with123I.
An intermediate neutron moderation method for measurement of moisture and/or hydrogen contents of small samples is presented.
The sample is placed on the top face of a neutron howitzer, with a cadmium sheet between. Thermal neutrons resulting from
intermediate neutron moderation in the sample are detected with a3He proportional counter placed on the sample, by a cadmium difference method. With a 500 mCi Am-Be neutron source, the limit
of moisture detection for a 10×20×1.8 cm3 asbestos plate in 1 min count time is 0.5 wt.%. The precision of measuring the hydrogen contents of 250 ml hydrocarbons containing
112 mg H/ml is 0.9% under the same conditions.
