Nonmetallic Loom

2017
Nonmetallic flexible loom is recommended for use as an insulated covering giving mechanical protection over insulated wire, metal tubing, or other parts requiring a water-, oil-, and acid-proof covering resistant to fire or abrasion. It is also recommended for use as a covering for copper or other metal tubing to prevent crystallization and to ...

Splendid Isolation for a Nonmetallic Dication

Angewandte Chemie International Edition, 2009
AbstractConfined, but happy: The triflate salt of a germanium(II) dication, an atomic cation of a nonmetal, was isolated by encapsulation in [2.2.2]cryptand (see formula and molecular structure in the crystal). The cryptand satisfies the electron demand of the cation and sterically protects it (see space‐filling depiction, right).magnified ...

Fields in Nonmetallic Waveguides

Proceedings of the IRE, 1948
An infinite plate of dielectric material is taken as the prototype of nonmetallic waveguides. The Green's function is found for the case in which the electric field is parallel to the surfaces of the plate. The solution is set up as a Fourier integral, which is then replaced by a complex contour integral.

Bipolarons in nonmetallic crystals

Journal of Structural Chemistry, 1986
The binding energy of a bipolaron in an ionic crystal increases substantially in the case of strong anisotropy of the effective masses of the free carriers of the easy plane type or easy axis type. In the second case the polaron is cigar-like in shape and the coaxial configuration of bipolarons is energetically favorable.

Nonmetallic Conducting Films

Physics, 1934
Immutable conducting films, which adhere to any clean solid have been formed from synthetic resin solutions holding finely ground carbon in suspension. Values of surface resistivity for uniformly thin films were secured in the range 15 to 106 ohms referred to unit area of surface. When the thickness is held constant, the resistivity depends mainly upon

Reaction of Compounds of the Nonmetallic Elements

1983
The pyrolysis of the boranes is a topic of continuing interest. Lipscomb et al. (1) have published calculations that cast doubt on the long-held view that in the pyrolysis of diborane the decomposition of B3H9 an adduct of BH3 and B2H6 is a rate-determining stage.

Nonmetallic Electrode Materials

1981
This chapter is devoted to nonmetallic electrode materials, i.e., electrode materials which are neither metallic, nor semiconducting. A large portion of this chapter deals with materials which have proved their worth in actual processes, e.g., carbon and graphite, and another part describes new materials that may prove of much value to the scientist ...

Sintering of Nonmetallic Nitrides

1987
Experimental data are presented on densification of boron, aluminium and silicon nitrides during continuous heating with constant rate and depending on isothermic holding time at constant temperature. The principles are considered for densification of differently dispersed nitride powders under nitrogen pressure.

Some Problems of the Nonmetallics

Geological Society of America Bulletin, 1930
Introduction In a presidential address delivered before this Society not long ago, the former speaker divided such addresses into two groups. To the one belonged those in which the retiring president sought to develop some favorite theory of his own; to the other those which in general treated of the progress of some particular science or branch ...
