Emerging technology for shielding of electromagnetic radiation using composite materials

This study indicated that multi-walled carbon nanotubes (MWCNTs)-epoxy composites can be used as effective lightweight shielding materials. The measurement results showed that highest EMI SE of 23.4 dB at 8 GHz was obtained for nanocomposite with 1 wt% MWCNTs. Dielectric properties and electrical conductivity values were supplemented by microscopic studies.

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

A review on neutron shielding performance of nano-composite materials

Neutron sources employed in different applications in both medicine and industry. Due to the harmful effects of neutron particles on living organisms, radiation shields have played a vital role in radiation protection against neutrons. In recent decade, numerous investigations conducted on the design and fabrication of nanocomposites as more efficient shielding materials against fast and therma...

Shielding factors for vehicles to gamma radiation from activity deposited on structures and ground surfaces.

This paper describes a measuring procedure for the determination of shielding factors for vehicles passing through areas that have been contaminated by activity released to the atmosphere from a reactor accident. In open areas the radiation field arises from an infinite plane source. In urban areas the radiation field consists of the contribution from fallout deposited on a road and on the buil...
