“…Microwave irradiation produces an efficient internal heat that can result in a direct and uniform heating on the mixed reactions. The reflection and diffusion on the local barrier cause the occurrence of hot spots and superheating effects as reported previously [7][8][9][10][26][27][28]. There were also reported that ionic conduction (crystalline) and nonionic conduction (amorph) occur in celluloses.…”

“…Therefore, they are useful for a further optimization of both the experimental parameters and the used equipment. In a number of experiments important and interesting from both theoretical and practical point of view non-thermal effects of the microwave processing have been observed and studied [59].…”

Correspondence should be addressed to idehara@fir.u-fukui.ac.jpIn this paper, we present the recent progress in the development of a series of gyrotrons at FIR UF that have opened the road to many novel applications in the high-power Terahertz science and technology. The current status of the research in this actively developing field is illustrated by the most representative examples in which the developed gyrotrons are used as powerful and frequency tunable sources of coherent radiation operating in a CW regime. Among them are high-precision spectroscopic techniques (most notably DNP-NMR, ESR, XDMR, and studies of the hyperfine splitting of the energy levels of positronium), treatment and characterization of advanced materials, new medical technologies.

“…For example we can control briquette's microstructure by using certain heating rate or by using appropriate technology such as microwave energy. Application microwave for processing materials have been reported by several scholars [12][13][14]. By using this waves as an alternative energy for heating, the microstructure as well as mechanical property of ceramics can be improved [15][16][17].…”

Abstract.A study has been conducted about the quality of young coal (brown coal ) briquettes from North Kolaka to determine the effect of varied adhesive on the proximate characteristics and calorific value. The young coal briquettes were made by using adhesives of starch, cassava starch and Castor oil plant starch at a concentration of 5 to 15% of the total mass. The grain size of young coal and the adhesive used were 60 mesh and 100 mesh, respectively. The samples were molded in a cylindrical mold with a diameter of 2.5 cm and a high of 6 cm, and with a pressure of 100 kg/cm 2 . After having been compacted, the young coal samples were then analyzed proximately i.e. moisture content, volatile matter, ash content and fixed carbon, as well as their calorific values calculation. The results showed that the increase of the adhesive could tend to increased the water content and volatile matter, but reduced the ash content, and the fixed carbon tend to constant except coal briquettes using starch adhesive it were increased. The calorific value of the young coal briquettes increased for all kinds of adhesives when the adhesive increased. The calorific value per one gram ranged from 3162.7 cal/g to 4678.7 cal/g. The highest calorific value, 4678.7 cal/g, was observed at the adhesive of 15 % of starch. The characteristics of young coal can be used as a raw material for making high-calorie hybrid briquettes.
