2-Chlorobenzylidenemalononitrile (CS riot control agent) has been shown to produce a number of thermal degradation products when dispersed at high temperature. We hypothesized that these CS-derived compounds are formed by energy input from heating during the dispersion process. Here we identified organic CS-derived compounds formed from purified CS subjected to temperatures ranging from 300 to ...

Large grain polycrystalline silicon wafers have been subjected to post~annealing (900 °C/45 ruin) after POCI3 pre-diffusion at different temperatures. For the first time we have investigated the effect of the furnace starting and quenching temperature on the gettering efficiency. The optimisation of thermal cycle parameters include the determination of the best combination of starting temperatu...

SiC nanowires have been synthesized at 1,600 degrees C by using a simple and low-cost method in a high-frequency induction furnace. The commercial SiO powder and the arc-discharge plasma pretreated carbon black were mixed and used as the source materials. The heating-up and reaction time is less than half an hour. It was found that most of the nanowires have core-shell SiC/SiO(2) nanostructures...

Preform heating is one of the most important steps in the polymer fibre fabrication process due to the potential distortion that can be introduced when exposing the structure to high temperatures. Such heating is further complicated when internal air-structures are introduced into the preform such as in Microstructured Polymer Optical Fibre (MPOF) preforms. The aim of this study was thus to inv...
