Authors: Morita Eugene Hayato , Hayashi Hidenori , Tasumi Mitsuo 
Published: May 2006

Abstract
The light-induced infrared difference spectra have been measured for chromatophores (intracytoplasmic membranes containing reaction centers) and isolated reaction centers from Rhodobacter sphaeroides at 300 and 80 K. Analysis of the C9 keto carbonyl stretching region suggests that the radical cation of the bacteriochlorophyll-a special pair formed after photoexcitation might have multiple structures which differ in the degree of delocalization of an unpaired electron.

Authors: Kobayashi Toshi-aki , Sakakura Toshiyasu , Hayashi Teruyuki , Yumura Morio , Tanaka Masato 
Published: May 2006

Abstract
High molecular weight poly(methylsilylene) is obtained in a good yield through dehydrogenative condensation of methylsilane catalyzed by (C5Me5)2NdCH(SiMe3)2. At a high temperature, polymerization process involves cross-linking via the loss of methane. Pyrolysis of the resulting polymer gives β-SiC in a high yield. Blend with a carbon-rich polymer like poly(phenylsilylene) is effective to prevent the formation of contaminative metallic silicon during ceramization.

Authors: Okamoto Yuko , Kikuchi Takeshi , Kawai Hikaru 
Published: May 2006

Abstract
The efficiency of the Monte Carlo simulated annealing method for prediction of the low-energy structures of Met-enkephalin is examined with the exact ECEPP function. Among the 40 obtained conformations, eleven, including the lowest-energy conformation, exhibit structure similar to the tertiary structure predicted by the Monte Carlo with minimization method. The average energy of these conformations are considerably lower than those of the remaining conformations. These findings prove the effectiveness of the method.
