Comments on Intermetallic Thermochemistry

The need of a concerted multi-disciplinary approach in the investigation of intermetallic systems and the role of thermochemistry are underlined. The activity carried out in the Author’s laboratory in the alloy thermodynamics is summarized. The different instruments (calorimeters) built in laboratory are briefly presented and their performance discussed. The results obtained in the measurement ...

The Physical and Metallurgical

To attempt to optimize the anomalous phenomena that today go under the label "cold fusion" the experimentalist should be aware of the many aspects of the behavior of hydrogen in metals and of its entry into and egress from metals. This paper discusses the equilibrium characteristics of the isotopes of hydrogen in metals. The first section discusses the thermodynamics of the terminal solutions o...

Potential Energy Surfaces for the Reaction of O Atoms with CH3I: Implications for Thermochemistry and Kinetics

The geometries of IO, HCIO, ICH2O, CH3IO, CH3OI, CH2IOH, and ICH2OH have been obtained at the HF and MP2(FU)/6-31G(d) levels of ab initio theory, and the HF/6-31G(d) frequencies are compared with experimental assignments where these are available. The Gaussian-2 method was used to provide thermochemical data for use in atmospheric and combustion modeling. Transition states that connect these sp...

Radical thermochemistry and organic reactions*

Most free radicals are transient species and it is therefore difficult to measure their thermochemical properties. We have used two new techniques that address this problem. Photoacoustic calorimetry was used to measureheats of formation of free radicals and thus homolytic bond strengths, while photomodulated voltammetry was used to measure their oxidation and reduction potentials. The data off...
