Over the last decade, a great deal of attention has been devoted to study the inflammatory response upon exposure to multi/single-walled carbon nanotubes (CNTs) and different fullerene derivatives. In particular, carbon nanoparticles are reported to provoke substantial inflammation in alveolar and bronchial epithelial cells, epidermal keratinocytes, cultured monocyte-macrophage cells, etc. We s...

High-dose ionizing irradiations can cause acute tissue and organ damage, especially severe cutaneous lesions. These cutaneous injuries often result in further complications and incur high mortality. Therefore, it is critical to develop effective therapeutic approaches for acute high-dose ionizing irradiation injury. Intracellular reactive oxygen species (ROS) have been implicated in mediating i...

The endohedral fullerene molecule, N@C60, is a candidate for molecular spin qubits (quantum bits) and spin probes owing to its exceptional electron spin properties. Advancements in the processing of N@C60 are key to obtaining samples of high purity on a reasonable timescale. We investigate enrichment by high throughput processing (flow rate of 18 L h(-1) and operating pressure of 1.5-2 MPa) usi...

The synthesis and properties of large spherical molecules and giant clusters is a fascinating field in contemporary chemistry, unifying all areas of organic/supramolecular, inorganic, and coordination chemistry as well as organometallic chemistry. Recent developments of low-valent group 13 metalloid clusters,1 chalcogeno-bridged copper, and silver clusters2 as well as giant polyoxomolybdates3 r...

ehemical modification of fullerenes such as the C60 molecule is a promising way to generate novel materials with tailored properties. Exohedral insertion of atoms in the interstitial sites of the Coo solid has created a new class of superconductors. Encapsulation of atoms in the fullerene cage is expected to lead to stable M@C(,() endohedral complexes with a very interesting optical response. W...

DFT calculations and X-ray crystallography were used to directly compare the reactivity of the convex carbon surfaces of C20H10-corannulene and the C60-fullerene toward the diruthenium(I,I) metal cluster.

Organic thin-film solar cells with a conducting polymer (CP)/fullerene (C60) interpenetrating heterojunction structure, fabricated by spin-coating a CP onto a C60 deposit thin film, have been investigated and demonstrated to have high efficiency. The photovoltaic properties of solar cells with a structure of indium-tin-oxide/C60/ poly(3-hexylthiophene) (PAT6)/Au have been improved by the insert...

The nature of chemical bonding and its effect on spin-polarized electron transport in Ni–C60–Ni are studied using density functional theory in conjunction with the Landauer–Büttiker formalism. The binding site on the C60 cage surface appears to have a strong influence on the electron tunneling current between Ni leads. The tunnel current has a much higher magnitude when Ni is bonded to hole sit...

Using ab initio spin-density-functional calculations, we investigate the electronic and magnetic structures of a C60 fullerene during a structural transition to a nanotube segment by a series of Stone-Wales transformations. We find that partly opened intermediate cage structures may acquire a magnetic moment of several Bohr magnetons. Our results offer a possible explanation for the ferromagnet...

We have used photoelectron spectroscopy to determine the energy-level alignment at organic heterojunctions made of manganese phthalocyanine (MnPc) and the fullerene C60. We show that this energy-level alignment depends upon the preparation sequence, which is explained by different molecular orientations. Moreover, our results demonstrate that MnPc/C60 interfaces are hardly suited for applicatio...
