Recently discovered carbon nanotubes have exhibited many unique material properties including very high thermal conductivity. Strong sp 2 bonding configurations in carbon network and nearly perfect self-supporting atomic structure in nanotubes give unusually high phonon-dominated thermal conductivity along the tube axis, possibly even surpassing that of other carbon-based materials such as diamond and graphite (in plane). In this chapter, we explore theoretical and experimental investigations for the thermal-transport properties of these materials.

Unusually High Thermal Conductivity of Carbon Nanotubes

The present status of the field of fluorescence yields, radiationless (Auger and Coster-Kronig) and radiative transition probabilities is summarized. Tables of experimental and theoretical results are included, and tables of "best values" of important quantities are presented.

X-Ray Fluorescence Yields, Auger, and Coster-Kronig Transition Probabilities

Publisher Summary This chapter illustrates the developments in the field of aeration since 1960, which have culminated in the modeling of the oxygen movements within the plant. The chapter collates the mathematical approaches to the aeration process and explains the concepts of modeling in a simplified manner. It is noted that the environment exerts a considerable influence on the directional flow of the respiratory gases within the plant and the directional exchange with the atmosphere. Oxygen can enter the plant body in a variety of ways. In non-aquatic species, the stomata and lenticels provide paths of low resistance for the entry and exit of both oxygen and carbon dioxide. In submerged astomatal aquatics, surface permeabilities are sufficiently high to allow the necessary gas transference. Plants rooted in unsaturated soils are exposed to an oxygen-rich environment over the greater part of their shoot and root surfaces. Oxygen enters the plant in the combined state as water. As water, it is transported from root to shoot in the xylem where a proportion is finally released into the liquid phase within the chloroplasts during the photolysis stage of photosynthesis.

THE changes which have been made in the new edition of this valuable manual of constants are mostly matters of detail. All the chemical data have been recalculated on the basis of the international atomic weights, and, with the co-operation of Dr. E. Griffiths, of the National Physical Laboratory, a revision of the heat tables has been attempted. Tables of atomic numbers, spark-gap voltages, X-ray wave-lengths, and terrestrial magnetic constants also find a place in the new edition, and more extended tables of the relative value of the acceleration of gravity have been added. The first edition received detailed notice in NATURE of February 8, 1912.Tables of Physical and Chemical Constants, and some Mathematical Functions.By Dr. G. W. C. Kaye Prof. T. H. Laby.
