The steady-state activity of the Ca(2+)-ATPase of skeletal muscle sarcoplasmic reticulum (SR) is low when reconstituted into bilayers of the long-chain phosphatidylcholines dierucyl phosphatidylcholine [di(C22:1)PC] or dinervonyl phosphatidylcholine [di(C24:1)PC]. In di(C24:1)PC the ATPase binds a single Ca2+ ion, whereas in di(C22:1)PC it binds two, as in the native SR [Starling, East and Lee ...

Fullerene (C(60)), the third carbon allotrope, is a classical engineered material with the potential application in biomedicine. However, extremely high hydrophobicity of fullerene hampers its direct biomedical evaluation and application. In this work, we investigated the solubilization of fullerene using 9 different solubility enhancers: Tween 20, Tween 60, Tween 80, Triton X-100, PVP, polyoxy...

A fullerene graph F is a cubic 3-connected plane graph with exact 12 pentagons and other hexagons. Let M be a perfect matching of F . A cycle C of F is M -alternating if and only if the edges of C appear alternately in and off M . A set H of disjoint hexagons of F is called a resonant pattern if F has a perfect matching M such that all hexagons in H are M -alternating. A fullerene graph F is k-...

Nanotechnology offers many societal benefits and this have prompted the rapid growth of engineered nanomaterials. Fullerene (C60) due to its unique properties has become an important nanomaterial in biomedical and biotechnological applications. Once in water, Fullerene forms stable suspended aggregates and thus become bioavalable to aquatic biota. The fate and transport of fullerene in the aqua...

Large protonated polycyclic aromatic hydrocarbons (H(+) PAHs) are possible carriers of unidentified infrared (UIR) emission bands from interstellar objects, but the characterization of infrared (IR) spectra of large H(+) PAHs in the laboratory is challenging. IR absorption spectra of protonated coronene (1-C24 H13 (+) ) and mono-hydrogenated coronene (1-C24 H13 (.) ), which were produced upon e...

Triazoliumfullerene was first prepared by the [3+2] cycloaddition of in situ generated 1,3-diaza-2-azoniaallene with fullerene and was characterized by the dispersed positive charge over the fullerene sphere associated with periconjugation. This new type of amphiphilic fullerene tended to form vesicles and crystalline aggregates after the casting of THF or MeOH solutions.

A novel Ag(I)-induced three-component annulation reaction of [60]fullerene with sulfonylhydrazones and nitriles has been developed for the efficient synthesis of diverse disubstituted [60]fullerene-fused dihydropyrroles. The reaction exhibits a broad substrate scope and excellent functional-group tolerance, and also allows for the synthesis of fullerene-bound macromolecules.

Well-dispersed mesoporous hollow silica-fullerene nanoparticles with particle sizes of ∼50 nm have been successfully prepared by incorporating fullerene molecules into the silica framework followed by a selective etching method. The fabricated fluorescent silica-fullerene composite with high porosity demonstrates excellent performance in combined chemo/photodynamic therapy.

in this paper, we calculate the eccentric connectivity index and the eccentricity sequence of two infinite classes of fullerenes with 50 + 10k and 60 + 12k (k in n) carbon atoms.
