چکیده

The paper reports computations for Al@C82, Sc@C82, Y@C82 and La@C82 based on encapsulation into the IPR (isolated pentagon rule) C2υ C82 cage and also on Mg@C74, Ca@C74, Sr@C74 and Ba@C74 based on encapsulation into the only C74 IPR cage. Their structural and energetic characteristics are used for evaluations of the relative production yields, employing the encapsulation Gibbs-energy terms and saturated metal pressures. It is shown that the results can be well related to the ionization potentials of the free metal atoms.

Computed Stabilities in Metallofullerene

This article reports computations for Al@C82, Sc@C82, Y@C82, and La@C82 based on encapsulation into the IPR (isolated pentagon rule) C2v C82 cage. Their structural and bonding features are also used for evaluations of the relative production yields, employing the encapsulation Gibbs-energy terms and saturated metal pressures. The results can be well related to the ionization potentials of the f...

The role of plant antioxidants in the synthesis of metal nanoparticles

In recent years, the number of reports of nanoparticle production using green methods has increased exponentially. Green methods of nanoparticle production are based on oxidation and reduction reactions in which metal ions are reduced to nanoparticles with the help of compounds in living organisms or their extracts, including antioxidants. The presence of biomolecules, including antioxidants in...

Unprecedented chemical reactivity of a paramagnetic endohedral metallofullerene La@C(s)-C82 that leads hydrogen addition in the 1,3-dipolar cycloaddition reaction.

Synthesizing unprecedented diamagnetic adducts of an endohedral metallofullerene was achieved by using 1,3-dipolar cycloaddition reaction of paramagnetic La@C(s)-C82 with a simultaneous hydrogen addition. The selective formation of two main products, La@C(s)-C82HCMe2NMeCHPh (2a and 2b), was first detected by HPLC analysis and MALDI-TOF mass spectrometry. 2a and 2b-O, which was readily formed by...

Molecular Dynamics Simulation of Nucleation and Growth of Single-Walled Carbon Nanotubes

Developments of large scale and high-purity generation technique of single-walled carbon nanotubes (SWNTs) [1] are desired for the practical applications of this fascinating new material. In addition to previously known laser-furnace [2] and arc-discharge [3] techniques, catalytic chemical vapor deposition (CCVD) methods [4] have been developed for the possible larger amount production with low...

Development of a Method for measuring Reactive Oxygen Radicals Levels In Vitro and Study the Effects of Vitamin C and E on Radical Production Reaction

Background: Free radicals and reactive oxygen species(ROS) are the most important factors in formation of oxidative stress reaction. Now, radical damage has been suggested to contribute to a wide variety of diseases such as Alzheimer, atherosclerosis and cancer. Transition metal ions in the presence of the various biomolecules produce these active compounds. The aim of this study is introducing...
