Iris florentina, Iris gemanica, Iris pallida, Irones, Irißorental Rhizomes o f Iris pallida and Iris florentina contain — increasing on storage — violet-like smelling C )4-ketones (irones 1 a—c) which develop by oxidative degradation of C3!-triterpenoids. The structure of these precursors is reported as well as the structure of respective C30-homologues. The unusual C3j-structures may derive bi...

The photoinduced electron transfer is studied computationally in several Saturn-shaped inclusion complexes of carbo-aromatic rings and C60 fullerene – C72?C60, C96?C60, C120?C60, C168?C60.

How to create novel desired structures by rational design of building blocks represents a significant challenge in materials science. Here we report a conceptually new design principle for creating supracolloidal fullerene-like cages through the self-assembly of soft patchy particles interacting via directional nonbonded interactions by mimicking non-planar sp2 hybridized carbon atoms in C60. O...

First-principles calculations were performed to compare the energies of 29 different fullerene structures, with mass number from 60 to 240, and of eight nonhelical graphite tubes of different radii. A quantity called the planarity, which indicates the completeness of the pi-bonding, is the single most important parameter determining the energetics of these structures. Empirical equations were c...

Background & Objective: The potent antioxidant property of fullerene C60 nanoparticles and their derivatives has been demonstrated in a wide range of in vitro and in vivo studies. Hence, we examined the effects of fullerene C60 on the oxidative stress parameters at brain and liver of rats in normal situation. Materials & Methods: The study was performed in two groups of Wistar rats (each group...

In this study, the effect of fullerene electron mobility on the composition of paraphenylenediamine and stability was studied. Using quantum chemistry calculations, the first combination of paraffenylenediamine in a single-full-time region connected with fullerene through carbon atoms was reported. Experimental research was simulated and optimized using GIS software. Then the NBO calculations w...
