The structure of a rubredoxin (Rd) from , an organism that grows optimally at 100 $^{circ}$ C, was determined using the neutron single-crystal diffractometer for biological macromolecules (BIX-3) at the JRR-3 reactor of JAERI. Data were collected at room temperature up to a resolution of 1.5 , and the completeness of the data set was 81.9 %. The model contains 306 H atoms and 50 D atoms. A total of 37 hydration water molecules were identified. The model has been refined to final agreement factors of = 18.6 % and $_{free}$ = 21.7 %. Several orientations of the O-D bonds of side chains, whose assignments from X-ray data were previously ambiguous, were clearly visible in the neutron structure. While most backbone N-H bonds had undergone some degree of H/D exchange throughout the molecule, five H atom positions still had distinctly negative (H) peaks. The neutron Fourier maps clearly showed the details of an extensive set of H bonds involving the ND $_{3}$ $^{+}$ terminus that may contribute to the unusual thermostability of this molecule.

analysis using high resolution synchrotron radiation photoemission spectroscopy for initial oxidation of H $_{2}$ O pre-adsorbed Si(001) surfaces induced by supersonic O $_{2}$ molecular beams at room temperature

Yoshigoe, Akitaka; Teraoka, Yuden

Atomic Collision Research in Japan, No.28, p.105 - 107, 2002/00

The oxidation states up to Si $^{4+}$ states were formed when the translational kinetic energy of O $_{2}$ was 3.0 eV. The time evolustions of each Si oxidation states were in situ measured by using the high resolution photoemission spectroscopy.The translational kinetic energy of 3.0eV randomly enhanced the oxidation on Si(001) surface up to the second layer Si backbonds. It was found that the Si $^{4+}$ was not observed, thus the dimer Si atoms at the top layer was not surrounded by four oxygen atoms at the initial oxidation stage.
