The invention concerns a 5-aminolevulinic acid ester (I) soln. for producing a pharmaceutical prepn. useful for diagnosing and/or treating tissue and/or cell pathologies by local radiation exposure using radiation emitted by a light source energy followed, ...
Na2MoO4 has been found to have a peculiar catalytic behavior. The CH2O formation starts after a period of time at 670 Deg. Then the yield increases and reaches a max. after 12 h. The catalyst undergoes an extensive phase transformation prior to becoming ac ...
A simple optical alignment system is described for adjusting the angle of the axis of rotation of an Andrews-Beams rotor in magic-angle NMR expts. A low-power ruby laser mounted between the horns of the magnet cryostat is used a light source. The beam from ...
For the development of an elec. rechargeable zinc/air battery, La0.6Ca0.4CoO3-catalyzed (perovskite) bifunctional oxygen electrodes and pasted zinc electrodes were prepd. and tested in a monopolar zinc/oxygen cell. In addn., a bipolar Zn/oxygen stack was t ...
The structure of the synthetic peptide CH3CO(Leu-Ser-Leu-Leu-Leu-Ser-Leu)(3)Lys-NH2 in trifluoroethanol/water 60/40 (volume ratio) was characterized by two-dimensional nmr spectroscopy. The peptide, closely related to the amphiphilic helix models designed ...
Enantiomerically pure L- and D-4-fluoro-3-nitrophenylalanines and L- and D-3-fluoro-4-nitrophenylalanines were obtained from their corresponding racemates via enzymic resoln. [on SciFinder (R)] ...
Six cyclic peptides, designed to act as topological templates in the TASP (template assembled synthetic protein) approach in protein de novo design, were investigated employing a 100-ps, 900-K molecular dynamics conformational search. The peptides are comp ...
For the development of a rechargeable zinc/air battery, La0.6Ca0.4CoO3-catalyzed (perovskite) bifunctional oxygen electrodes and pasted zinc electrodes were prepd. and tested in monopolar zinc/air cells. In addn., a bipolar Zn/air stack was tested using re ...
We present a comparative study of residue usage correlations of various organism protein sets of diverse phylogenetic species and of open reading frames of several large human viral genomes. Our correlation analysis reveals three major tendencies: (i) char ...
