Zn-Co metal organic frameworks coated with chitosand and Au nanoparticles for chemo-photothermal-targeted combination therapy of liver cancer

open access: yesFrontiers in Oncology, 2023
The toxic effects of chemotherapy drugs on normal tissues are still a major limiting factor in cancer treatment. In this paper, we report a metal-organic framework (Zn-Co ZIF) with chitosan-coated outer layer as a carrier for the drug adriamycin ...

P doped random C20 fullerite - model structure for fullerene-like CPx [PDF]

open access: yes, 2013
Carbon-based amorphous and fullerene-like (FL) thin films have a great potential due to their mechanical resiliency. TEM investigation and interpretation of results from FL structures embedded in bulk phases is not straightforward.

Isomerisations of the fullerenes

open access: yesCarbon, 1992
The Stone-Wales (pyracylene) rearrangement is a hypothetical mechanism for interconversion of fullerene isomers, accounting for mobility of the pentagons on the surfaces of these clusters. Two versions of the transformation, involving patches of 4 and 12 rings, respectively, can be defined.

Computational Computation of the Efferene Structure on the Para phenylene diamine [PDF]

open access: yesInternational Journal of New Chemistry, 2017
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

On the Excitation and Formation of Circumstellar Fullerenes [PDF]

open access: yes, 2012
We compare and analyze the Spitzer mid-infrared spectrum of three fullerene-rich planetary nebulae in the Milky Way and the Magellanic Clouds; Tc1, SMP SMC16, and SMP LMC56. The three planetary nebulae share many spectroscopic similarities. The strongest

Fusion mechanism in fullerene-fullerene collisions -- The deciding role of giant oblate-prolate motion

open access: yes, 2015
We provide answers to long-lasting questions in the puzzling behavior of fullerene-fullerene fusion: Why are the fusion barriers so exceptionally high and the fusion cross sections so extremely small? An ab initio nonadiabatic quantum molecular dynamics (
