Mechanism for visible light responses in anodic photocurrents at N-doped TiO2 film electrodes
Article Abstract:
A definite mechanism for the visible-light responses in water photooxidation (oxygen photoevolution) on N-doped TiO2, as revealed by photocurrent measurements with film electrodes is reported. It is observed that photocatalytic oxidation of organic compounds on N-doped TiO2 under visible illumination mainly proceed via reactions with surface intermediates of water oxidation of oxygen reduction in combination with the above mechanism.

Aggregation of spin labeled trichogin GA IV dimers: distance distribution between spin labels in frozen solutions by PELDOR data
Article Abstract:
Pulsed electron-electron double-resonance (PELDOR) and CW-ESR spectroscopies are applied to study the dipole-dipole interaction of spin labels in frozen glassy solutions of mono- and double-labeled analogues of the 22-residue, the head-to-tail covalent dimer of the peptaibol antibiotic trichogin GA IV. It is reported that no aggregation is detected in the MeOH solution.

Structural consequences of spin conversion in a sterically encumbered Ni(II) porphyrin
Article Abstract:
The comparison of crystal structure of pyridine-ligated high-spin Ni(II) porphyrin complex with unligated low-spin Ni(II) complex is presented. Results indicate the induction of a Ni core expansion caused by conversion to high-spin Ni(II) in nonplanar sterically encumbered porphyrins.
