Computational Analyses of Alkaloids as Green Corrosion Inhibitors on Fe(110).

One of the successful techniques developed for the inhibition of metal corrosion is the utilization of phytochemicals from plant extracts as corrosion inhibitors. Theoretical studies are utilized to predict how organic components behave on metal surfaces and can pave the way for the development and synthesis of innovative, efficient corrosion inhibitors. However, atomic-level insights into the inhibition mechanisms of these green components are still needed.

Ocular brachytherapy dosimetry for 103Pd and 125I in the presence of gold nanoparticles: a Monte Carlo study.

The aim of the present Monte Carlo study is to evaluate the variation of energy deposition in healthy tissues in the human eye which is irradiated by brachytherapy sources in comparison with the resultant dose increase in the gold nanoparticle (GNP)-loaded choroidal melanoma. The effects of these nanoparticles on normal tissues are compared between 103Pd and 125I as two ophthalmic brachytherapy sources. Dose distribution in the tumor and healthy tissues has been taken into account for both brachytherapy sources.

Gold nanoparticle-based brachytherapy enhancement in choroidal melanoma using a full Monte Carlo model of the human eye.

The effects of gold nanoparticles (GNPs) in 125I brachytherapy dose enhancement on choroidal melanoma are examined using the Monte Carlo simulation technique. Usually, Monte Carlo ophthalmic brachytherapy dosimetry is performed in a water phantom. However, here, the compositions of human eye have been considered instead of water.
