The first (N═N)2- complex of a rare-earth metal with an end-on dinitrogen bridge, {K(crypt)}2{[(R2N)3Sc]2[μ-η1:η1-N2]} (crypt = 2.2.2-cryptand, R = SiMe3), has been isolated from the reduction of Sc(NR2)3 under dinitrogen at -35 °C and characterized by X-ray crystallography. The structure differs

The geometries and electronic structures of icosahedral A13C (A = Sc, Y; C = 0, ±1, ±2) clusters have been determined at a range of multiplicities at each cluster charge, using density functional theory methods. These clusters demonstrate a complex electronic structure which provides insight into

Thickness has been proved to have significant influence on the physical properties of two-dimensional (2D) materials and their corresponding devices. Understanding the effect of the thickness of 2D insertions on the contact properties of metal-monolayer MoS2 interfaces (viz. metal-mMoS2 interfaces)

In previous studies nifedipine has been shown to limit infarct size during 24 h of regional ischemia in the dog. Using a closed chest embolization procedure, autoradiographic (141-cerium at onset of ischemia) microsphere risk zone analysis and tetrazolium staining, the ability of nifedipine to
