We present here the 7.0–8.7 μm spectrum of the bright reflection nebula NGC 7023. Our observations are made with the Short Wavelength Spectrometer (SWS) on the European satellite Infrared Space Observatory (ISO). The vibrational bands of the ionized fullerene C60 are expected at 7.11 and 7.51 μm, while those of the neutral fullerene C60 are expected at 7.0 and 8.45 μm. We estimate an upper limi...

The basic facts and fundamental properties of binary fullerene cocrystals are reviewed, focusing especially on solvates and salts of Buckminsterfullerene (C60), and hydrates of hydrophilic C60 derivatives. The examined properties include the lattice structure and the presence of orientational disorder and/or rotational dynamics (of both fullerenes and cocrystallizing moieties), thermodynamic pr...

We have demonstrated that the ability of fullerenes to form clusters is essential for the filling of single-walled carbon nanotubes in solution. In solutions where C60 exists in the form of discrete solvated molecules (e.g., in CS2) no fullerene encapsulation in nanotubes takes place, as the large molar excess of solvent compared to solute prohibits C60 from entering the nanotubes. However, in ...

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...

In this study, nano-sized fullerene C60 powder was sufficiently mixed with Cu₂SnSe₃ powder by ball milling method, and the C60/Cu₂SnSe₃ composites were prepared by spark plasma sintering technology. The fullerene C60 distributed uniformly in the form of clusters, and the average cluster size was less than 1 μm. With increasing C60 content, the electrical conductivity of C60/Cu₂SnSe₃ composites ...

The effect of anchoring groups on the optical and electrochemical properties of triphenylamine-thienothiophenes, and on the photovoltaic performance of DSSCs photosensitized with the prepared dyes, was studied using newly synthesized compounds with cyanoacetic acid or rhodanine-3-acetic acid groups. Precursor aldehydes were synthesized through Suzuki cross-coupling, whereas Knoevenagel condensa...

A series of Porphyrinic-CTF materials are synthesized under ionothermal condition with high surface areas (>3200 m(2)/g) and tunable pore sizes. The ZnP-CTFs exhibit high adsorption capacities and selectivity towards C₃H₈, and C₂H₆ over CH₄ as IAST prediction. Furthermore, we explore the utility of ZnP-CTF for gas chromatographic separation of the small hydrocarbons mixture based on their diffe...

Nanoconfined synthesized crystalline fullerene mesoporous carbon (C60-FMC) with bimodal pore architectures of 4.95 nm and 10-15 nm pore sizes characterized by XRD, TEM, nitrogen adsorption/ desorption isotherm and solid-state NMR, and the material was used for protein immobilization. The solid-state 13C NMR spectrum of C60-FMC along with XRD, BET and TEM confirms the formation of fullerene meso...

Dimorfolido-N-trichloroacetylphosphorylamide (HL1) and dimorfolido-N-benzoylphosphorylamide (HL2) as representatives of carbacylamidophosphates were synthesized and identified by the methods of IR, 1H, and 31P NMR spectroscopy. In vitro HL1 and HL2 at 1 mM concentration caused cell specific and time-dependent decrease of leukemic cell viability. Compounds caused the similar gradual decrease of ...
