Tc radiolabeling of palm shell charcoal: A preliminary study for potential lung ventilation scintigraphy agent.

To investigate the potential of activated carbon from palm kernel shell waste for Tc-radiolabeled nanocarbon aerosol, a new production technology for carbon-based Tc-radioaerosol from such a waste was developed. Treated-palm shell charcoal (t-PSC) was prepared by hydrothermal method to increase the surface area, followed by Tc radiolabelling optimization. The optimal Tc radiolabeling conditions resulted in an adsorption capacity of 21.

IL-6 and IL-10 Levels in Rats Blood Plasma as Immune Responses Post Radioiodine (I-131) Administration.

Objective: The purpose of this study was to analyze the effect of oral administration of radioiodine (I-131) on the immune responses (interleukin 6 and 10) as biodosimetry markers and to support clinical trials of I-131 solution.

Methods: The design of this study was an in vivo experimental study using twenty-seven male rats (Rattus norvegicus strain Sprague-Dawley) given 100 μL of I-131 solution at a dose of 260 μCi. Blood plasma was taken at 0.

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.

Biomolecule-Assisted Synthesis of Hierarchical Multilayered Boehmite and Alumina Nanosheets for Enhanced Molybdenum Adsorption.

The effective utilization of various biomolecules for creating a series of mesoporous boehmite (γ-AlOOH) and gamma-alumina (γ-Al O ) nanosheets with unique hierarchical multilayered structures is demonstrated. The nature and concentration of the biomolecules strongly influence the degree of the crystallinity, the morphology, and the textural properties of the resulting γ-AlOOH and γ-Al O nanosheets, allowing for easy tuning. The hierarchical γ-AlOOH and γ-Al O multilayered nanosheets synthesized by using biomolecules exhibit enhanced crystallinity, improved particle separation, and well-defined multilayered structures compared to those obtained without biomolecules.

Template-Free Fabrication of Mesoporous Alumina Nanospheres Using Post-Synthesis Water-Ethanol Treatment of Monodispersed Aluminium Glycerate Nanospheres for Molybdenum Adsorption.

This work reports the template-free fabrication of mesoporous Al O nanospheres with greatly enhanced textural characteristics through a newly developed post-synthesis "water-ethanol" treatment of aluminium glycerate nanospheres followed by high temperature calcination. The proposed "water-ethanol" treatment is highly advantageous as the resulting mesoporous Al O nanospheres exhibit 2-4 times higher surface area (up to 251 m g ), narrower pore size distribution, and significantly lower crystallization temperature than those obtained without any post-synthesis treatment. To demonstrate the generality of the proposed strategy, a nearly identical post-synthesis "water treatment" method is successfully used to prepare mesoporous monometallic (e.
