It is shown that the delta bond, as found particularly in the Re(2)(6+) and Mo(2)(4+) cores of hundreds of compounds, provides a paradigm for the behavior of two-electron bonds of all types. By control of the angle of twist around the M-M axis, the strength of the bond can be systematically varied. By means of conventional electronic spectroscopy, nuclear magnetic resonance spectroscopy, and tw...

High-resolution solid-state NMR spectroscopy can provide structural information of proteins that cannot be studied by X-ray crystallography or solution NMR spectroscopy. Here we demonstrate that it is possible to determine a protein structure by solid-state NMR to a resolution comparable to that by solution NMR. Using an iterative assignment and structure calculation protocol, a large number of...

High-resolution proton NMR spectroscopy is well-established as a tool for metabolomic analysis of biological fluids at the macro scale. Its full potential has, however, not been realised yet in the context of microfluidic devices. While microfabricated NMR detectors offer substantial gains in sensitivity, limited spectral resolution resulting from mismatches in the magnetic susceptibility of th...

over the past decade, the chemical behavior of flavonoids as antioxidants has become the subject ofintense experimental research. plants represent a main source of natural antioxidants that might serveas leads for the development of novel drugs. malva sylvestris l. known to have various medicinalproperties since several decade ago, were evaluated for their antioxidant compounds ,most of thesebi...
