Recent development of nano/micro-scale analytical techniques for nuclear materials(1)

DEVELOPMENT OF A PELLET SCALE MODEL FOR TRICKLE BED REACTOR USING CFD TECHNIQUES

In this study, a pellet scale model was developed for trickle bed reactor utilizing CFD techniques. Drag coefficients were calculated numerically at different velocities and bulk porosities in the case of single phase flow through the dry bed. The simulation results were then compared with the prediction of Kozeny-Carman (K-C) equation. The results indicated that drag coefficients calculated fr...

Recent advances in analytical techniques for the determination of xylitol

Xylitol is a naturally occurring five-carbon containing sugar alcohol. It has attracted a lot of attention in the pharmaceutical, cosmetics, food, and dental industries due to its high sweetening ability, anticariogenic properties and possibilities for use in insulin-dependent diabetics. Thus, the establishment of a simple and rapid method for the determination of xylitol with high selectivity ...

Preservatives for Industrial Materials1

A wide variety of materials used in manufactured items are subject to microbiological deterioration. Those materials which are of chief concern include textiles and cordage, paper, leather, paints, plastics and plasticizers, rubber, waxes, and wood. The organisms responsible for microbiological deterioration, their mode of attack, and effects on materials, have been reviewed (Greathouse et al.,...

Isotopic and nuclear analytical techniques for health and environment.

Nuclear and related analytical techniques for life sciences

Place and role of nuclear analytical techniques (NATs) in life sciences is discussed. Examples of radioanalytical investigations at the IBR-2 pulsed fast reactor in Dubna illustrate the environmental, biomedical, geochemical and industrial applications of instrumental neutron activation analysis.
