This work proposes a new approach to fabricate highly transparent and flexible composite films that exhibit enhanced UV-shielding properties. Lignin has innate UV-shielding properties. However, when purified lignin, which is conventionally extracted through chemical treatment, is mixed with polymeric materials, its presence negatively influences the transparency of the resulting composite.
Lead Bricks use for Radioactive Shielding and Radiation Shielding Lead Bricks Lead is an important material because of its property to radiate the harmful radiation, thus acting as a shield in place of Nuclear works and X-ray regions. Lead Bricks are basically the rectangular bricks with
It is an object of the present invention to provide a method for manufacturing a radiation-shielded coating material based on a flame spray direct coating and a polymer-based radiation shielding material produced thereby. To this end, the present invention provides a method comprising: (1) mixing a polymer and a radiation shielding material; And a step (step 2) of coating the mixture prepared ...

Novel MMCs that shield neutron and γ-ray simultaneously are synthesized. • Neutron and γ-ray shielding effects of Al-based Gd 2 O 3-W MMCs are calculated.. Monoclinic Gd 2 O 3, amorphous, Al 3 Gd and Gd 3 Al 5 O 12 are produced during ball milling.. The chemical reactions are promoted by sintering and nanoparticles are distributed uniformly.
