Electron spin resonance characterisation of sedimentary quartz of different grain sizes

MAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON

The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...

Segmentation of Sedimentary Grain in Electron Microscopy Image

This paper describes a novel method developed for the segmentation of sedimentary grains in electron microscopy images. The algorithm utilizes the approach of region splitting and merging. In the splitting stage, the marker-based watershed segmentation is used. In the merging phase, the typical characteristics of grains in electron microscopy images are exploited for proposing special metrics, ...

Electron Spin Resonance of Biomolecules

Electron Spin Resonance

The vast majority of magnetic resonance imaging and spectroscopic investigations make use of nuclear magnetic resonance (NMR), exploiting the interactions of atomic nuclei with applied static and radiofrequency magnetic fields. Nevertheless, there exists another important “flavour” of magnetic resonance, called Electron Spin Resonance (ESR) – or, interchangeably, Electron Paramagnetic Resonance...
