Tungsten–platinum μ-carbido and μ-methylidyne complexes

Synthesis and characterization of μ-nitrido, μ-carbido and μ-oxo dimers of iron octapropylporphyrazine.

Three μ-X bridged diiron octapropylporphyrazine complexes having Fe(III)-O-Fe(III), Fe(+3.5)-N[double bond, length as m-dash]Fe(+3.5) and Fe(IV)[double bond, length as m-dash]C[double bond, length as m-dash]Fe(IV) structural units have been prepared and characterized by UV-vis, EPR, X-ray absorption spectroscopy and electrochemical methods. Single crystals of all the complexes were obtained fro...

The Crab Nebula at 850 Μ Μ Μ Μ Μm

Observations of the Crab Nebula at 850 µm made with the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope are presented. A variety of chop-throws and scanning directions was used in these observations, to well sample structure over a range of scales and directions. The resulting image, which was restored using a MEM algorithm, has a resolution of 17 arcsec, ...

Search for the rare decays B0s→μ+μ− and B0→μ+μ−

Search for D+(s)→π+μ+μ− and D+(s)→π−μ+μ+ decays

Article history: Received 24 April 2013 Received in revised form 3 June 2013 Accepted 4 June 2013 Available online 7 June 2013 Editor: L. Rolandi A search for non-resonant D(s) → π+μ+μ− and D(s) → π−μ+μ+ decays is performed using proton– proton collision data, corresponding to an integrated luminosity of 1.0 fb−1, at √ s = 7 TeV recorded by the LHCb experiment in 2011. No signals are observed a...
