Hydrogenolysis of alcohols was carried out using n-heptane solvent and Ir ReOx/SiO2 catalyst, which has been known to be active in water solvent. Hydrogenolysis of trans-1,2-cyclohexanediol proceeded more smoothly in n-heptane than in water. The maxi

High (≥95 % C) yields of n-hexane and n-pentane were obtained by hydrogenolysis of aqueous sorbitol and xylitol, respectively, at 413-443 K by using the Ir-ReOx /SiO2 catalyst combined with H-ZSM-5 as a cocatalyst and n-dodecane as a cosolvent. The

Hydrogenolysis of tetrahydrofurfuryl alcohol to 1,5-pentanediol and other related substrates such as 3-hydroxytetrahydrofuran and 1,2-cyclohexanediol proceeds over Ir–ReOx/SiO2 catalyst. TOF values are higher than those of Rh–ReOx/SiO2, which has

Modification of Rh/C with Re species enabled chemoselective hydrogenolysis of tetrahydropyran-2-methanol to 1,6-hexanediol. In particular, the Rh–ReOx/C (Re/Rh ratio=0.25) catalyst gave a high yield of 1,6-hexanediol (84 %) and showed a very low ac

The abundances of both orthogonal and nearly aligned neutron stars among the disk population millisecond pulsars appear to be excessively large, relative to those of canonical pulsars. Both of these excesses are expected in strongly spun-up neutron s

We investigate the behavior of the high frequency quasi-periodic oscillations (QPOs) in 4U 0614+091, combining timing and spectral analysis of RXTE observations. The energy spectra of the source can be described by a power law (alpha ~ 2.8) and a bla

We model the polarization properties of line emission from an accretion disk under a range of assumptions about the source function and electron-scattering optical depth tau(sub es). For small values of tau(sub es) and modest viewing angles, polariza

The strong optical emission of the Crab pulsar allows us to study the polarization properties in detail. Optical pulsed emission can best be understood as synchrotron radiation of relativistic electron-positron pairs in the outer magnetosphere. We ca

RECENT observations indicate that a typical globular cluster may contain hundreds of millisecond pulsars1,2. Because millisecond pulsars have some similarities to the Vela pulsar, which is known to be a source of γ-rays, they could also be gamma emi
