Enumeration of a class of IPR hetero-fullerenes [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
Hetero-fullerenes are fullerenes in which some of the carbon atoms are replaced by other atoms. This paper uses the Pólya theorem to count the number of their possible positional isomers and chiral isomers. To do this, the computer algebra system GAP was

Modeling C540-C20 Fullerene Collisions

open access: yesReviews on Advanced Materials Science, 2018
Collisions of C20 and C540 fullerenes are studied in a wide range of velocities by means of classical molecular dynamics. The simulations show that the collision scenario strongly depends on the collision velocity of the fullerenes.

Formation of Water-Soluble Fullerenes [C60,C70] under Ultrasonication and Antioxidant Effect

open access: yesEurasian Chemico-Technological Journal, 2003
The water-soluble fullerenes [C60, C70] are prepared with fullerenes [C60, C70] and a mixture of oxidants (v/v) at the ratio of 3:1 under ultrasonic condition at room temperature.

Predicting the new carbon nanocages, fullerynes: a DFT study

open access: yesScientific Reports, 2021
In this study, based on density functional theory, we propose a new branch of pseudo-fullerenes which contain triple bonds with sp hybridization. We call these new nanostructures fullerynes, according to IUPAC.

Progress in Antiviral Fullerene Research

open access: yesNanomaterials, 2022
Unlike traditional small molecule drugs, fullerene is an all-carbon nanomolecule with a spherical cage structure. Fullerene exhibits high levels of antiviral activity, inhibiting virus replication in vitro and in vivo.

MOLECULAR-DYNAMIC SIMULATION OF MIXTURES OF MODIFIED FULLERENES AND 1,8-OCTANDITHIOL

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2021
In this work, we report on the results of comparative atomistic modeling of two systems containing functionalized fullerenes of phenyl-C61-butyric acid methyl ester (PC61BM) and phenyl-C71-butyric acid (PC71BM) in the presence of a high-boiling solvent 1,

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

open access: yesAdvanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

The ways to form fullerens structure exemplified by С28 and С30 isomers

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics
The systematization of possible ways to form C28 and C30 fullerene isomers has been completed in this work. An additional confirmation was obtained that fullerenes created by incorporating dimers into the initial structure had a minimum energy. Two other

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

open access: yesAdvanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...
