Development of a polystyrene-based microplastic model for bioaccumulation and biodistribution study using radiotracing and nuclear analysis method.

The investigation of micro or nano plastics behavior in the environment is essential to minimize the hazards of such pollutants on humans. While the conventional method requires sophisticated procedures and a lot of animal subjects, the nuclear technique confers a sensitive, accurate, and real-time method using radiolabeled micro or nano plastics as a tracer. In this study, polystyrene sulfonate-based microplastic (PSM) was developed with a size of around 3.

Green synthesis of alumina nanoparticle using Hibiscus rosa-sinensis leaf extract as a candidate for molybdenum-99 adsorbent.

AlO nanoparticle is effectively used as an adsorbent for the low specific activity of molybdenum-99 (Mo). The AlO nanoparticle was synthesized by the green synthesis method using Hibiscus rosa-sinensis leaf extract (HRE). The AlO nanoparticle synthesized using 10% of the HRE has a crystallite size of 4.

Surface modification of acid-functionalized mesoporous gamma-alumina for non-fission Mo/Tc generator.

Mesoporous gamma-alumina (MGA) was synthesized for neutron-activated Mo adsorbent. Acid functionalization of the MGA was carried out to enhance the Mo adsorption capacity and the Mo breakthrough profile. The acid-treated MGA has a more positive particle charge, rougher surface, smaller particle and pore size, larger surface area, and wider pore distance.
