Synthesis of C58 Open-Cage Fullerene Derivatives
Synlett, 2016Several analogous C 58 open-cage fullerene derivatives have been prepared through silver acetate mediated decarboxylation of the corresponding C 59 open-cage precursors. These C 58 open-cage fullerene derivatives can trap one water molecule under mild conditions as shown by spectroscopic data and single-crystal X-ray analysis.

Desorption of C60 upon thermal decomposition of cesium C58 fullerides
The Journal of Chemical Physics, 2012A monodispersed fullerene material comprising exclusively C58 cages was doped with Cs to generate CsxC58 films of various compositions. The resulting modified properties have been studied using a variety of surface analysis methods with emphasis on thermal desorption and ultraviolet photoelectron spectroscopies.

A theoretical study on certain C58 species
Journal of Molecular Structure: THEOCHEM, 2001Abstract Various electronic states of C 58 structure which is theoretically obtained from C 60 molecule by removing a C 2 unit and deleting a C–C bond shared by two adjacent hexagons have been considered for AM1 (UHF) type semiempirical molecular orbital calculations.

Molecular analysis of the recA gene of Agrobacterium tumefaciens C58
Gene, 1992The complete nucleotide sequence of the Agrobacterium tumefaciens recA gene was determined. A comparison of the translated open reading frame of the gene with other known recA sequences revealed significant sequence conservation. However, unlike its Escherichia coli equivalent, A.

Informational Structure of Agrobacterium Tumefaciens C58 Genome
2007Base-base correlation (BBC) method, based on information theory, translates a DNA sequence into a 16-dimensional vector. It has proven quite effective in distinguishing various functional regions on one chromosome. In this study, we explore the potential use of distinguishing different chromosomes within one species, with particular emphasis on ...

Time-resolved kinetic energy releases for C60·+ → C58·+ + C2
International Journal of Mass Spectrometry and Ion Processes, 1997Time-resolved kinetic energy release (KER) measurements were performed on an ion trap/reflectron mass spectrometer. The average KER for C2 evaporation from C60·+ was observed to decrease with increasing precursor ion lifetime. This constitutes proof that the KER is due to the non-fixed energy in the transition state rather than to a reverse activation ...

Indoleacetic acid production: A plasmid function of Agrobacterium tumefaciens C58
Biochemical and Biophysical Research Communications, 1979Abstract Indoleacetic acid (IAA) production is regulated by the 117 Mdalton pTi plasmid that is harbored by the crown gall bacterium Agrobacterium tumefaciens strain C-58. In the presence of tyrosine, about 5- to 10-fold higher IAA production (0.8–0.9 μg/ml) occurs in strain C-58 than in the plasmidless avirulent derivative strain NT1. The high

Isomers of Fullerenes C58 to C60
We have designed possible structures of isomers of fullerenes from C58 to C60. The fullerenes studied refer to four-, five- and six-fold symmetry, they being divided into two classes, perfect (basic) having ordinary symmetry and intermediate having topological symmetry.Melker, A. I. +2 more
