A review with 30 refs. on some of the authors works on the absorption, excitation and emission spectra of C60 embedded in rare gas matrixes while stressing the role of the environment. The gas phase resonant 2-photon ionization spectrum of C60 is reanalyze ...
The energy redistribution processes in C60 trapped in low temp. rare gas solids have been studied using one- and two-color femtosecond pump-probe spectroscopy. The data show an ultrafast internal conversion process, followed by a slower electronic relaxati ...
The ribonucleoside-derivs. serve for the synthesis of ribonucleic acids and comprise a triple substituted silyloxymethyl-group as a protection-group on the oxygen atom in 2'-position. The ribonucleoside-derivs. may be suitably protected on the nucleobase a ...
The isolation and characterization of Ln(NO3)3 complexes (Ln=La, Pr, Nd, Eu, Tb, Lu) with 2,3-benzo-1,4,7,13-tetraoxa-10-azacyclo-penta-decane (L1) and two of its N-substituted derivatives (L2, L3) are reported. Structural information in the solid state is ...
Zinc(II) phthalocyanine (ZnPC) is a new photosensitizer currently undergoing phase I and II clinical trials at Lausanne's CHUV hospital for the photodynamic therapy (PDT) of early cancer in the upper aerodigestive tract. Activated oxygen species other than ...
A review with 55 refs. Oxygen is a key substrate in animal cell metab. It has been reported that the oxygen uptake rate (OUR) is a good indicator of cellular activity, and even under some conditions, a good indicator of the no. of viable cells. The measure ...
The recent development of temperature controlled scanning tunneling microscopy opened the door to a fascinating new world on the nanometer scale. The atomic scale information obtained provides unprecedented insight into the kinetics of surface phenomena su ...
The partial oxidn. of toluene over V2O5/TiO2 catalysts is a reaction of industrial interest. In spite of the detailed study of the nature of surface vanadia species, there is an evident lack of the information concerning their reactivity. The present work ...
Plasma treatment of PET films was carried out under argon, followed by exposure to an oxygen atmosphere. The films underwent considerable changes in surface composition and morphology, as demonstrated by contact angle measurements, FTIR-ATR, AFM, and XPS. ...
Meta(tetrahydroxyphenyl)chlorin (m-THPC) is a new photosensitizer currently undergoing clin. trials at Lausanne's CHUV hospital for photodynamic therapy (PDT) of early cancer in the upper aerodigestive tract. The illumination of m-THPC with light at 650 nm ...
