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...
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 ...
The prepared Cu@CS-FP as a dip catalyst was examined for ATRP reaction of methyl methacrylate as model polymerization reaction which represented the high catalytic activity and recyclability. It should be noted that this is an example of the use of dip catalyst as a novel catalyst for ATRP ...
A series of ZnO/Fe2O3/g-C3N4 photocatalysts were synthetized by impregnation of g-C3N4 with Zn(NO3)2·6H2O, and Fe(NO3)2·9H2O followed by calcination. The morphology, chemical composition, and structure of the resulted materials were carefully analyzed
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 ...
32、s of the domain Rc and downstream length Lo should be specified in such a way that the domain size will not affect the simulation results,42,Example of CFD Process (Physics),No heat transfer,43,Example of CFD Process (Mesh),Grid need to be refined near the foil surface to resolve ...
The excited electron-hole pair can go through several paths as follows: the semiconductor can donate electrons on the surface to reduce the adsorbed acceptor (𝐴/𝐴−A/A−), for example, oxygen (lane c). Holes can migrate to the surface and electrons from donors (D/D+) can join ...
The DPO, TEF, DPD and DEF will be obtained, and the influences of the regenerator’s effectiveness on the performance indexes will be analyzed. Taking the DPD as an example, the optimal HCDs among heat exchangers under maximum DPD will be gained. Based on the NSGA-II algorithm, the DPO,...
[]. In general, some suspension polymerisation processes require special precautions to be taken. For example, when using PS, styrene-methyl-poly(divinylbenzene) (PDVB), methacrylate and polyurethane as shell materials nitrogen gas protection facility should be available during the fabrication process,...
