The DSC (Differential Scanning Calorimetry) analysis of heavy ozonized C60 fullerene (known also as “fullerene ozopolymer”), shows the exothermal decomposition of this compound with a peak at 158°C with a decomposition enthalpy ΔHdec ≈ −322 kJ/mol and an activation energy for the decomposition E# = 71 kJ/mol. These experimental facts confirm the

We define and study a family of cubic surfaces in the projectivized tangent bundle over a four dimensional projective space associated to the root system D_5. The 27 lines are rational over the base and we determine the classifying map to the moduli space of marked cubic surfaces. This map has degree two and we use it to get short proofs for some

We present first insights into the far-IR properties for a sample of IRAC and MIPS 24 μm detected Lyman break galaxies (LBGs) at z ~ 3, as derived from observations in the northern field of the Great Observatories Origins Survey (GOODS-N) carried out with the PACS instrument on board the Herschel Space Observatory. Although none of our galaxies are

Inversions of spectropolarimetric observations of penumbral filaments deliver the stratification of different physical quantities in an optical depth scale. However, without establishing a geometrical height scale, their three-dimensional geometrical structure cannot be derived. This is crucial in understanding the correct spatial variation of
