Abstract: Nuclear magnetic resonance (NMR) relaxometry, a noninvasive and nondestructive method, is a key technique for unconventional reservoir evaluation. Echo data detected from NMR instrument, a ...

Abstract: Nuclear magnetic resonance (NMR) logging is an effective method for evaluating petrophysical parameters and fluid identification, and it is significantly promising for unconventional ...

Guwahati: In a breakthrough for India’s plant-based pharmaceutical research, scientists from Assam have discovered a novel bioactive compound from Curcuma caesia Roxb., commonly known as black ...

Researchers use Nuclear Magnetic Resonance (NMR) spectroscopy in a diverse range of scientific domains to explore the characteristics of organic molecules. The inherent magnetic characteristics of ...

The NMR spectrum (¹H-NMR and ¹³C-NMR) is a graphical representation of nuclear resonance signals, with chemical shift (ppm) on the x-axis indicating the electronic environment of nuclei, the y-axis ...

In 2014, Agilent Technologies announced that it would stop selling nuclear magnetic resonance systems. Agilent, which had acquired its NMR rival Varian in 2010, continued to fulfill existing orders, ...

An initial step of most NMR studies is identifying peaks in the obtained spectrum. Producing a peak list is especially crucial if the spectrum is automatically prepared. Peak picking is still ...

Hidden underground: in November engineers tested the NMR detectors in a minefield in Angola where it could reliably sense explosives buried up to 15 cm underground — the typical depth of a deployed ...
