Abstract Labeling in diffusion measurements by pulsed field gradient (PFG) NMR is based on the observation of phase nuclear spins acquired a constant magnetic with purposefully superimposed gradients. This labeling does no way affect microdynamics and provides information about probability distribution molecular displacements as function time. An introduction measuring principle followed detail...

Water has a significant impact on the properties of building materials. A nuclear magnetic resonance (NMR) spectrometer can be used to detect water in materials and measure its distribution nondestructively, rapidly, accurately. In this paper, novel method is introduced for using single-sided NMR content (WC) materials, including brick, sandstone, mortar, concrete. The signal intensity these we...

The effects of water/oil volume ratio, type and concentration of demulsifier, water salinity and mixing speed on the average water droplets size in water-oil emulsion are evaluated at different times through NMR measurements.The type and concentration of demulsifier have the greatest effects on the average droplet size with 38% and 31.5%, respectively. The water/oil volume ratio, water salinity...

Microfluidic stripline NMR technology not only allows for NMR experiments to be performed on small sample volumes in the submicroliter range, but also experiments can easily be performed in continuous flow because of the stripline’s favorable geometry. In this study we demonstrate the possibility of dual-channel operation of a microfluidic stripline NMR setup showing oneand twodimensional H, C ...

In this study, we cultured Chlorella vulgaris cells with a range of lipid contents, induced via nitrogen starvation, and characterized them via flow cytometry, with BODIPY 505/515 as a fluorescent lipid label, and liquid-state 1H NMR spectroscopy. In doing so, we demonstrate the utility of calibrating flow cytometric measurements of algal lipid content using triacylglyceride (TAG, also known as...

The origins of the line—shape method for determining the rates of chemical and conformational equilibration by NMR spectroscopy are reviewed for the purpose of illustrating the factors which should be considered in obtaining accurate rate data by this very useful technique. Besides a number of illustrations of how changes in rates of conformational equilibration change NMR spectra taken from th...

We report an electronic magnetization measurement of a quantum point contact (QPC) based on nuclear magnetic resonance (NMR) spectroscopy. We find that NMR signals can be detected by measuring the QPC conductance under in-plane magnetic fields. This makes it possible to measure, from Knight shifts of the NMR spectra, the electronic magnetization of a QPC containing only a few electron spins. Th...

With SGF Profiling™ we introduce an NMR-based screening method for the quality control of fruit juices. This method has been developed in a joint effort by Bruker BioSpin GmbH and SGF International e.V. The system is fully automated with respect to sample transfer, measurement, data analysis and reporting and is set up on an Avance 400 MHz flow-injection NMR spectrometer. For each fruit juice a...
