Microwaves have been widely used in the treatment of different materials. However, the existing adjustable power thermostatic reactors cannot be used to analyze materials characteristics under microwave effects. In this paper, a microwave thermostatic chemical reactor for processing liquid materials is proposed, by controlling the velocity of coolant based on PLC (programmable logic controller)...

This proposed design for a mini thermonuclear reactor uses a method based upon a series of important innovations. A cumulative explosion presses a capsule with nuclear fuel up to 100 thousands of atmospheres, the explosive electric generator heats the capsule/pellet up to 100 million degrees and a special capsule and a special cover which keeps these pressure and temperature in capsule up to 0....

Over the past several years our research has focused on the development of classical regression models that describe the disposition process occurring in an electro-spouted bed system. Previous analyses addressed the development of linear regression models that related the chemical plating process to electric current levels, liquid flow rates and bed geometry, i.e. intrinsic engineering paramet...

The loading of MOX (Mixed Oxide) fuel in BWRs (Boiling Water Reactors) is considered in this paper in a “once-through” strategy. The fuel assemblies are of the General Electric 8×8 type, whereas the reactor is of the General Electric BWR/6 type. Comparisons with traditional UOX (Uranium Oxide) fuel assemblies revealed that the loading of MOX fuel in BWRs is possible, but this type of fuel creat...

OBJECTIVE To develop a coated electrode of immobilized denitrificants and to evaluate the performance of a bioelectrochemical reactor to enhance and control denitrification. METHODS Denitrifying bacteria were developed by batch incubation and immobilized with polyvinyl alcohol (PVA) on the surface of activated carbon fiber (ACF) to make a coated electrode. Then the coated electrode (cathode) ...

The decomposition of 5-benzhydryl-1H-tetrazole in an N-methyl-2-pyrrolidone/acetic acid/water mixture was investigated under a variety of high-temperature reaction conditions. Employing a sealed Pyrex glass vial and batch microwave conditions at 240 °C, the tetrazole is comparatively stable and complete decomposition to diphenylmethane requires more than 8 h. Similar kinetic data were obtained ...

The electrical properties of MIS structures with silicon oxynitride films, deposited at 200 C in a RF-plasma CVD reactor using Si(OC2H5)4 (TEOS) as a precursor and nitrogen as the gas ambient have been studied. The analysis of the capacitance-voltage and current–voltage characteristics has shown that a larger DC bias yields larger densities of dielectric charge and interface traps in the growin...

Extracting energy from biomass is an important alternative to produce different types of energy (heat, electricity, or both) assuring low pollution and better efficiency. It is a new yet reliable approach to reduce green gas emission by extracting methane from industry effluents and use it to power machinery. We focused in our project on using paper and mill effluents, treated in a UASB reactor...

Makoto Tanigawa received his Bachelor’s degree in Nuclear Engineering in 1997 from The Pennsylvania State University and subsequently worked as a reactor core analysis engineer for Westinghouse Electric Company. In 2003, he obtained a Master’s degree in Electrical Engineering from University of Twente in the Netherlands. He spent 3.5 years at ASTRON (Netherlands Institute for Radioastronomy) de...
