This article describes a Group (VI) modified Co-Zr-B amorphous nano alloys were prepared in situ ultrasound-assisted reduction by sodium borohydride in an aqueous solution. Co-Cr-Zr-B, Co-Mo-Zr-B and Co-W-Zr-B powders were characterized by XRD, FESEM, BET and ICP techniques. No distinct peak...

Current driven by electron Bernstein waves (EBW) and by the electron bootstrap effect are calculated separately and concurrently with a kinetic code, to determine the degree of synergy between them. A target {beta} = 40% NSTX plasma is examined. A simple bootstrap model in the CQL3D...

The mechanics of the flowing granular materials such as coal, agricultural products, at deal of attention as it has fertilizers, dry chemicals, metal ores, etc. have received a great deal of attention as it has relevance to several important technological problems. Despite wide interest and more...

OAK-B135 The authors have initiated an experimental program to address some of the questions associated with operation of a tokamak with high bootstrap current fraction under high performance conditions, without assistance from a transformer. In these discharges they have maintained stationary...

Pyrolysis and gasification processes of three types of lignocellulosic biomass (Eucalyptus wood, fir wood and pine bark) and biomass main components (cellulose, xylan and lignin) were studied by thermogravimetric-mass spectrometric analysis. Biomass samples were pyrolyzed between 30 °C and...

The kinetic characteristics of pulverized coal combustion in the two-phase flow were studied using the micro fluidized bed kinetic analyzer (MFBKA) so as to get closer to the actual working condition. On the basis of the performance of CO and CO2 emissions, the effect of various operating...
