Electron energy-loss spectroscopy is an electron microscope technique with high spatial resolution and a powerful tool for identifying the arrangement of heteroatoms. However, structural information regarding the configuration and distribution of heteroatoms is difficult to obtain using existing analytical ...
Since the knowledge of the electron configuration of elements is necessary for understanding the nature of chemical bonding, and in turn the structure of a perfectly ordered, periodic arrangement of atoms or ions, it is discussed in the first chapter. This chapter starts with the basic knowledge ...
For frozen samples, further treatment involves fracturing and sublimation of the ice; therefore, the internal structure of the sample can be visualized, such as the arrangement of nanoparticles at the interface of droplets or bubbles [119,151]. For specific food systems, the continuous phase is ...
The positively charged capsule, Co6L46+, is defined by an alternating arrangement of four deprotonated ligands (L3−) on its eight triangular faces with a cavity of approximately 1350 Å3 and four robust, triangle-shaped openings having a Co…Co separation about 14.5 Å (Fig. 2a)...

The dynamics of discharge propagation and x-ray generation in nanosecond pulsed fast ionisation wave in 5 mbar nitrogen In this work, the propagation of fast ionisation wave (FIW) discharges driven by negative nanosecond high-voltage (HV) pulses and the x-ray spectrum from t... B Huang,C Zh...
This arrangement enables EPR and ENDOR experiments to be performed simultaneously on the sample. In CW ENDOR, the EPR signal usually most intense (at a given field) is partially saturated by an increase of MW power and followed by sweeping the RF to obtain the ENDOR spectrum. When the RF ...
