Fast light

In addition to the color and the tinctorial strength, which ate very important factors for the molecular design of anthraquinone dyes, affinity for fibers, various kinds of fastness (light, wet, sublimation, nitrogen oxides (NO ) gas, washing, etc), and apphcation properties (sensitivity for dyeing temperature, pH, etc) must be considered thoroughly as well. [Pg.309]

In another example rather similar electrochemically generated anion radicals of anthracene and 9,10-diphenylanthracene were excited by visible light and found to give a greater than 10-fold increase in the rate of reductive dechlorination of 4 chlorobiphenyl. The kinetic results suggested a fast light-assisted reduction pathway implying either the photoexcited anion radical or an electron ejected from it [183]. [Pg.128]

Technical Observations. Phenylmethylpyrazolonesulfonic acid is used, for example, in the preparation of fast light yellow G (page 265). Phenylmethylpyra-zolone itself (from phenylhydrazine and acetoacetic ester) and maiw of its derivatives are valuable components for the preparation of yellow azo eyes which, for the most part, are characterized by very high stability. [Pg.332]

A comparison with Table 1 shows that these advanced substrates are designed for close-coupled application, where fast light-off, low back pressure, and compact size are most critical [17,18]. [Pg.25]

As such a monolith is different from a fluidized bed, which also shows a limited pressure loss, but in combination with serious axial dispersion in the emulsion phase at least. A major distinction between monolith and fluidized-bed reactors, however, concerns heat transfer rates to the surroundings. The latter are applied when heat effects due to reaction are to be compensated, while monolithic reactors can be considered as adiabatic for most practical purposes. In automotive exhaust gas treatment, adiabatic behavior is even stimulated by insulation of the reactor wall to promote a fast light-off of the reactor after a cold engine start. [Pg.209]

Light speed—How fast light gets from one place to another. The speed of light depends on the material through which it must travel. [Pg.134]

This definition for the meter lasted only until 1983. Scientists then decided to define a meter by how fast light travels in a vacuum. This system is even more exact than the one based on krypton-86. [Pg.298]

A direct measurement of the electronic energy loss as a function of the impact parameter is a hard task to be performed from the experimental point of view and only a few experiments have been performed for fast light ions. Experiments in gas targets under single collision condition provide a more direct and precise comparison of the theoretical results with the experimental data. Here we compare the results of the coupled-channel method for collisions of protons with He as a function of the projectile scattering angle. [Pg.33]
