Chemical methods of producing structural ceramics are currently of considerable interest because traditional, power-based processing techniques appear incapable of yielding components that can satisfy advanced performance requirements in a cost effic

Conditions for blood storage are chosen to assure adequate levels of adenosine triphosphate (ATP) and 2,3-diphosphoglycerate (2,3-DPG). Because of the invasive nature of the techniques, biochemical assays are not routinely used to measure levels of t

The N1 imino units in Escherichia coli tRNAfMet, tRNAGlu, tRNAPhe, and tRNATyr were studied by 1H-15N NMR using three different techniques to suppress signals of protons not attached to 15N. Two of the procedures, Fourier internuclear difference spec

Diphenylphosphinoethyltriethoxysilane and alkylsilylating reagents have been reacted with silica gel to produce a surface with anchored ligands within a hydrophobic matrix. The extent of surface coverage has been determined using elemental analysis d

Cross-polarization of nuclei (I) with a low magnetogyric ratio is one of the pillars of many modern solid state NMR experiments, enhancing the sensitivity often by an order of magnitude. Cross-polarization is based upon cross-relaxation in the rotati

Mixed-mode bonded phases consisting of diphenylphosphinoethylsilane concurrently immobilized with octadecyldimethylsilane were synthesized. Elemental analysis and solid-state nuclear magnetic resonance (NMR) spectroscopy were employed in order to cha

Techniques for the correlation of 1H and 15N chemical shifts based on zero and double quantum NMR are discussed. The indirect determination of nitrogen shifts from the proton signals provides a dramatic gain in sensitivity over direct observation of
