Abstract The definition of ‘clay’ was first formalized in 1546 by Agricola. It has been revised many times since, although the fundamentals involving plasticity, particle size, and hardening on firing were retained by most. For an exhaustive account of the history of the definition to 1963, the reader is referred to M…
The Raman spectrum of polycrystalline vaterite is presented and compared to spectra of calcite and aragonite, the other two common CaCO3 polymorphs; Raman spectroscopy easily distinguishes between these three polymorphs. An important feature of the Raman spectrum of vaterite is splitting of both the ν1 and ν4 peaks. T…

Abstract Monte Carlo modeling of electron‐solid interactions requires a detailed and accurate supply of experimental data on which to base its physics and against which to test its predictions. To meet this need, a collection of data—comprising measurements of secondary and backscattered electron yields, electron stop…
Two approaches have been adopted in attempting to determine the strength of the one-phonon infrared absorption by the B nitrogen aggregate in diamond. On the one hand, we have heat treated purely type IaA specimens with known infrared absorption strengths (and thus also known nitrogen concentrations) to bring about pa…
Jute fiber is an important agricultural product. It is one of the most common natural fibers in Third World countries such as India, China, Bangladesh, etc. The jute industry has special importance in the economy of India and continues to be a major traditional earner of foreign exchange. However, it is facing tough c…
Structural evidence for the microsegregation of alkalis in oxide glasses is reviewed and the implications for ionic transport, viz., nearest-neighbor hopping, cooperative and correlation effects, are considered. Distinctions are drawn between the hopping of alkalis in silicate glasses, where changes in the configurati…
Biosynthetically directed fractional 13C labeling of proteinogenic amino acids is achieved by expression of proteins on a minimal medium which contains a mixture of [13C6]glucose and glucose with natural isotope abundance as the sole carbon source. Subsequent hydrolysis of the proteins yields the free amino acids. The…
A homogeneous assay method based on the long-lived fluorescence of rare earth cryptates and amplification by nonradiative energy transfer has been developed for immunoassays. The principles of the assay allow a double discrimination of the emitted signal through spectral and temporal selectivity. The cage structure of…

The preparation of ceramic materials from preceramic compounds provides a means for the synthesis of new materials which cannot be obtained by conventional methods. An example is shown in the figure, which shows carbon‐fiber‐reinforced silicon carbide coated with silicon carbonitride prepared by dip‐coating the substr…
