Lithium fluoride (LiF) is an efficient and widely used cathode buffer layer (CBL) in bulk heterojunction polymer solar cells (PSCs). The LiF thickness is normally limited to 1 nm due to its insulting property. Such small thickness is difficult to precise control during thermal deposition, and more importantly, 1-nm-thick LiF cannot provide sufficient protection for the underlying active layer. ...

We have performed molecular dynamics simulations of atomistic models of C60 molecules and DMPC bilayer membranes to study the static and dynamic effects of carbon nanoparticles on biological membranes. All four C60-membrane systems were investigated representing dilute and concentrated solutions of C60 residing either inside or outside the membrane. The concentrated C60 molecules in water phase...

The effect of a water-soluble malonic acid derivative of carboxyfullerence (C60) against Escherichia coli-induced meningitis was tested. C60 can protect the mice from E. coli-induced death in a dose-dependent manner. C60 administered intraperitoneally as late as 9 h after E. coli injection was still protective. The C60-treated mice had less tumor necrosis factor alpha and interleukin-1beta prod...

The electrical resistance of thin silver films deposited on C60 crystals shows anomalies near 261, 240, and 100 K. These temperatures coincide, respectively, with the bulk rotational, surface rotational, and quenched disorder structural phase transitions of crystalline C60. Films of other metals on C60 show similar behavior. Our findings demonstrate that thin metal film overlayers are sensitive...

Ternary planar heterojunction organic solar cells (PHJ-OPVs) were fabricated using three small molecules, alpha-sexithiophene (α-6T), aluminum phthalocyanine chloride (AlPcCl) and fullerene (C60). These molecules can be easily sublimated under a vacuum; they have complementary optical absorption spectra their energy band structure alignment is favorable for electronic charge transfers. Moreover...

We have demonstrated that the external quantum efficiency (EQE) of organic photovoltaic cells with a heterojunction zinc phthalocyanine (ZnPc) and fullerene (C60) bilayer films, which are used as donor an acceptor, respectively, is improved by photopolymerization (photon energy: 2–4 eV light fluence: 0.4 W cm−2) between adjacent C60 molecules via [2 + 2] cycloadditional four-membered ring. Comp...

We examine a variant of so-called carbon nanotube peapods by packing C60 molecules inside the open edge ducts of collapsed carbon nanotubes. C60 insertion is accomplished through a facile single-step solution-based process. Theoretical modeling is used to evaluate favorable low-energy structural configurations. Overfilling of the collapsed tubes allows infiltration of C60 over the full cross-se...

Fullerene C60 as a representative of carbon nanocompounds is suggested to be promising agent for application in photodynamic therapy due to its unique physicochemical properties. The goal of this study was to estimate the accumulation of fullerene C60 in leukemic cells and to investigate its phototoxic effect on parental and resistant to cisplatin leukemic cells. Stable homogeneous water colloi...

The adsorption of Th(IV) onto the surface of oxidized multi-walled carbon nanotubes (oMWCNTs) in the absence and presence of hydroxylated fullerene (C60(OH)n) and carboxylated fullerene (C60(C(COOH)₂)n) has been investigated. C60(OH)n, C60(C(COOH)₂)n and oMWCNTs have been chosen as model phases because of their representative in carbon nano-materials family. Adsorption experiments were performe...

Fullerene (C60) has shown great potential in drug delivery. In this study we exploited modified fullerene (diadduct malonic acid-fullerene-Asn-Gly-Arg peptide [DMA-C60-NGR]) as an antitumor drug carrier in order to build a new tumor-targeting drug delivery system. We also investigated the synergistic enhancement of cancer therapy using photodynamic therapy (PDT) induced by DMA-C60-NGR and 2-met...
