An example of the thermal decomposition of a crystalline polymer — poly(l,6-bis(N-carbazolyl)-2,4-hexadiyne)The thermal decomposition of poly(1,6-bis(N-carbazolyl)-2,4-hexadiyne) crystals, prepared by gamma radiation, was examined over a range of experimental conditions, the most ...
The above example represents one method of measuring the inertia by a transient test, applying a step voltage through a suitablelimiting resistor. An alternative would be to take a speed/time curve as the machine slows down under the action of a known torque, e.g. themechanical loss. Fromeq...
1982). This type of stress model application will become more important in the future to optimize the design of the new molds being developed for continuous thin-slab and strip casting. In twin-roll strip casting, for example, thermal distortion of the rolls during operation is of the same ...
Thus, we obtain a set of linear equations, shown here for the example of an intermediate with two links to other intermediates. $$\frac{{{\mathrm{d\theta }}_{\mathrm{n}}}{{{\mathrm{dt}}} = k_{n - 1}{\mathrm{\theta }}_{{\mathrm{n}} - 1} + k_{ - n}{\mathrm{\theta...
The composition of unknown polymer samples can be quickly characterized by means of combined TGA/DSC-FTIR measurements. This article describes a typical example. Introduction A TGA/DSC directly coupled to an FTIR spectrometer can be used to investigate the decomposition products of a material while ...
At a distance of 50 kpc, the Large Magellanic Cloud (LMC) is a convenient environment for searching for the extragalactic counterparts of the accreting MYSOs known in the Milky Way. For example, there is the recent detection of subparsec scale molecular outflows8,9, as well as the discove...
This requires careful synthesis of the geometrical design of the component, material selection and its manufacturing process with a close interaction among the three stages. In the traditional design and development approach, however, consideration of these interactions is weak. For example, in the ...
Figure 11.4(b) shows an example of the type of decomposition possible. The idea of using a decomposition process to form individual elements, rather than geometric primitives has also been explored. In this technique, a geometry is continuously sectioned until the remaining portions are simple ...
This method is frequently used for determination of the solubility of gaseous elements in steels. An example of such an analysis in systems of our interest is the thermal decomposition of NaH [50]. Dissociation of NaH(s) to Na(l) and H(g) in a previously evacuated container is relatively...
Methods of finding thermal conductivity have been studied by many researchers, as an example we refer to works [1–5]. However, when it comes to practical application of the developed methods, the new circumstances are found out that are not taken into ac- count in the theoretical development...
