In contrast with conventional single molecule junctions, in which the current flows parallel to the long axis or plane of a molecule, we investigate the transport properties of M(II) 5,15 diphenylporphyrin (M DPP) single molecule junctions (M=Co, Ni, Cu, or Zn divalent metal ions), in which the current flows perpendicular to the plane of the porphyrin. Novel STM based conductance measurements combined with quantum transport calculations demonstrate that current perpendicular to the plane (CPP) junctions have three orders of magnitude higher electrical conductanc than their current in plane (CIP) counterparts, ranging from 2.10’2 G0 for Ni DPP up to 8.10’2 G0 for Zn DPP. The metal ion in the center of the DPP skeletons is strongly coordinated with the nitrogens of the pyridyl coated electrodes, with a binding energy that is sensitive to the choice of metal ion.
If you missed Jimmy Fallon Tim Tebow/David Bowie match up last night on his NBC show (or you haven happened to stumble upon it as it gone viral online today), don fear you can catch an encore on Morgan Tonight this evening at 9pmET/PT. (just watch) came about since Fallon already had a Bowie impression ready. Rooting for the guy, Fallon tells Piers Morgan.
Turning just her head back to the girl as she kept walking, a snicker in line when her next words started to form on her lips. Got a hot date with my boyfrie Lucy face turned sour as the woman started, yeah, I can tease you about that anymore. Aquarius pouted dramatically before winking..
Some alarming numbers on the future of coral reefs were confidently stated in the latest IPCC report, “coral reefs are projected to decline by a further 70 90% at 1.5 with larger losses (>99%) at 2 “. Since the industrial revolution in the 19th century, human activities have contributed to approximately 1.0 of global warming. At our current rate of emissions, global warming is estimated to reach 1.5 between 2030 and 2052.
