Hosoya entropy analysis of some fullerene structures [PDF]

open access: yesDiscover Nano
This study examines the structural complexity of fullerene graphs using Hosoya entropy as a measure. The entropy values were calculated for various fullerene structures, including $$F^s_{3,1},$$ F 3 , 1 s , $$F^s_{4,2}$$ F 4 , 2 s and fullerenes ranging ...

Studying the Formation of Fullerenes During Catagenesis [PDF]

open access: yesMolecules
The formation of polycyclic aromatic hydrocarbons (PAHs) during catagenesis does not exclusively lead to planar structures. The inclusion of five-ring elements increases the curvature of PAHs and yields bent molecules.

Harnessing cosmic carbon: anaerobic microbial responses to fullerenes under early Earth conditions [PDF]

open access: yesFrontiers in Microbiology
Fullerenes of extra-terrestrial origin may have been accessible as carbon sources for anaerobic microorganisms on the early Earth. Very little is known about how anaerobic microorganisms respond to and use fullerenes and their soluble derivatives.

Radical Scavenging Mechanism and Antioxidant Effect of Fullerenes in Lubricating Oils (Part 3)

open access: yesTribology Online, 2023
Zinc dithiophosphate (ZnDTP) is used in lubricating oils as an antioxidant. However, its use has been discouraged because it contains phosphorus, which has a high environmental burden.

Structural Studies of Giant Empty and Endohedral Fullerenes

open access: yesFrontiers in Chemistry, 2020
Structure elucidations of giant fullerenes composed of 100 or more carbon atoms are severely hampered by their extremely low yield, poor solubility and huge numbers of possible cage isomers.

The ways to form midi-fullerens structure exemplified by С22, С24 and С26 isomers

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2023
In this paper, the possible ways of forming the midi-fullerene isomers, namely C22, C24 and C26, have been systematized. Three simplest mechanisms for their synthesizing are known.

Biochemical and tensometric analysis of C(60) fullerenes protective effect on the development of skeletal muscle fatigue [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2021
The protective effect of water-soluble C60 fullerenes on the development of slow and rapid fatigue of rat skeletal muscles was analyzed. It was found that the reduction of muscle contraction force (muscle soleus) by 50% of the initial values is almost ...
