Volatilization Phenomena and Chemical Reactions

1966
In § I.I we introduced the term ‘sample excitation’ to denote the group of processes that determine the radiation output of the source for a given sample. In theory, the aggregate of processes can be treated in separate steps; in practice, the processes take place jointly, however, and observed intensities therefore reflect overall effects.

Transfer Phenomena and Chemical Kinetics

2010
Fundamental physical quantities such as mass, momentum and energy can be exchanged between portions of a system, or created during transformations through different processes such as convection, diffusion and chemical reactions. Convection is a type of mass exchange that is dependent upon the mean material velocity.

Chemical Phenomena at the Surface of Nanoparticles

2001
In principle, the precise knowledge of the composition and the structure of a material allows the determination of the bulk properties. In a reverse way, the reproducibility of the composition and structure of the material should ensure the reproducibility of the material properties.

Chemical Nature of Seismic Phenomena

2001
It has been shown that, in comparison with basalts, the products formed as a result of the processes of magma generation, earthquakes, volcanic activity, formation of lamproite and kimberlite tubes and others are enriched with light mantle elements.

An Organic Framework for a Philosophical Appreciation of Chemical Phenomena

Annals of the New York Academy of Sciences, 2003
Abstract: The aim of this paper is to show how chemistry gives rise to philosophical reflection. Initially, some general remarks on philosophy and science are offered in the light of recent reductive controversy surrounding them both. An appeal is made for a broader and deeper outlook.
