Relationships between the intra-ring wood density assessed by X-ray densitometry and optical anatomical measurements in conifers. Consequences for the cell... The objective of this work is to compare anatomical measurements to wood density variations within annual rings of three major softwood species...
The meaning of DUAL-ENERGY X-RAY ABSORPTIOMETRY is absorptiometry in which the density or mass of a material (such as bone) is measured by comparing the material's absorption of X-rays of two different energies and which is used especially for determinin
▲Figure 1: Schematic view of X-ray reflection for cases when the incident angle is lower and higher than the critical angle, θc. ▲Figure 2: Simulated XRR profile for a single layer system. The critical angle (determined by film density) and Kiessig fringes (determined by layer thickness...
However, measurements of the power density spectrum are modified by the effects of deadtime in X-ray detectors. In this work, we focus on the Proportional Counter Array (PCA) instrument of the Rossi X-ray Timing Explorer (RXTE), an orbiting observatory that offers fast, microsecond-level ...

This is ascribed to the little electron density difference between PNSs and water. The part of PNSs immersed in water is almost “invisible” to the incident X-ray beam, therefore the part exposed in air constitutes the main scattering signal (~1000 times more than the part immersed in ...
X-ray absorption spectroscopy (XAS) has become an indispensable tool to in situ investigate dynamic natures of electrocatalysts but still suffers from limited energy resolution, leading to significant electronic transitions poorly resolved. Herein, we highlight advanced X-ray spectroscopies beyond ...
