At the nanometer scale, solutions involving magnetic resonance force microscopy and NV-centers have contributed to a paradigm shift16,17,18, and even opening up new horizons in the field of miniaturised quantum sensors. As an additional strategy, striplines have resolved a number of challenges ...

The ability to correlate a spectrum to a precalibrated chart accurately (to within 0. 02 ppm) has made chemical shift, along with the character of the spectral lines produced, an increasingly important tool in configurational analysis-a tool which this book is designed to complement. It is ...
The resulting scores plots of PC1 versus PC2 flagged up a few distinct outliers in different NMR chemical shift regions (Fig. 15). Under comprehensive consideration of PCA results and their anti-BCG activity, especially those active fractions with improved activity comparing to the corresponding ...
