A new generation of micro-scale, nuclear magnetic resonance (CapNMR™) probe technology employs two independent detection elements to accommodate two samples simultaneously. Each detection element in the Dual-Sample CapNMR Probe (DSP) delivers the s

The principles and parameters to consider when choosing an NMR probe for analysis of a volume- or mass-limited sample are identified and discussed. In particular, a capillary-based microflow probe is described which has a mass sensitivity comparable

A specially designed microcoil probe for use in biomolecular NMR spectroscopy is presented. The microcoil probe shows a mass-based sensitivity increase of a minimal factor of 7.5, allowing for the first time routine biomolecular NMR spectroscopy with

We have used NMR to study the effects of adding alkali metals (Na, K, Rb, or Cs) to silica supported platinum clusters. Alkali metals are frequently added to metal catalysts, and to other catalysts as well, to serve as ‘promoters’. We have also e

We describe here experiments evaluating the performance of solenoidal radio frequency probes having submillimeter dimensions (microcoils) as detectors for liquid nuclear magnetic resonance (NMR) in very low-homogeneity (100 ppm/cm) magnetic fields. P

We have observed the NMR lineshape for 109 Ag in the paraelectric, incommensurate and commensurate phases of the 3 q incommensurate insulator proustite (Ag 3 AsS 3 ). In the paraelectric phase we observed discrete narrow lines representative of the s

Complement-induced granulocyte aggregation is suspected as a cause of the adult respiratory distress syndrome. Quantifying the lung damage in these patients is difficult, and complement levels combined with clinical parameters of oxygenation might he
