Abstract This article is devoted to the study of heating kinetics, temperature fields, as well determining laws non-stationary heat transfer processes during treatment melon fruits with IR rays. These studies, in turn, make it possible determine time desired under different radiation conditions, which a necessary condition for achieving positive effect infrared radiation. At same time, fields a...

Physical stability of synthetic skin samples during their exposure to microwave heating was investigated to demonstrate the use of the metal-assisted and microwave-accelerated decrystallization (MAMAD) technique for potential biomedical applications. In this regard, optical microscopy and temperature measurements were employed for the qualitative and quantitative assessment of damage to synthet...

Continuous flow microwave heating is a promising alternative to conventional heating for aseptic processing of low-acid vegetable purees. However, non-uniform temperature distribution and control of processing parameters are the major hurdles in the implementation of continuous flow microwave heating. This study was undertaken to overcome issues associated with the scale-up of a continuous flow...

The mechanical size reduction of solids is an energy intensive and highly inefficient process. Therefore, there is great incentive to improve the efficiency of size reduction and mineral separation processes. Over several decades, this has promoted significant amounts of research,unfortunately, this has only led to small, incremental improvements in efficiency. One area which has shown signific...

Microwave heating has been shown to influence various inorganic chemical reactions. Substantial reductions in the synthesis time for materials have been reported (1). Additionally, product characteristics and quality of materials synthesized by microwave heating are different from those synthesized under conventional heating methods. The mechanism which results in microwave enhancement is not c...
