Summary
A new compact X-ray microscope offers versatile non-destructive testing. This hybrid instrument combines micro-computed tomography (micro-CT) and high-resolution microscopy for detailed 3D sample analysis.
Area of Science:
- Materials Science
- Physics
- Engineering
Background:
- Non-destructive testing (NDT) is crucial for miniaturized industrial and medical applications.
- X-ray microscopy provides 3D volumetric data through computed tomography (CT).
Purpose of the Study:
- To describe a novel compact X-ray microscope for advanced NDT.
- To highlight its hybrid capabilities for multi-modal analysis.
Main Methods:
- Development of a compact hard X-ray microscope (9 keV) utilizing a liquid-metal-jet source.
- Implementation of two distinct operational modes: micro-CT without optics and magnified X-ray microscopy with optics.
- Enabling mode switching without sample repositioning.
Main Results:
- Micro-CT mode achieves 1 μm resolution for millimeter-sized samples.
- Microscopy mode resolves features down to 150 nm.
- The instrument integrates both modes seamlessly for comprehensive sample investigation.
Conclusions:
- The developed instrument advances laboratory-based multi-mode X-ray microscopy.
- It offers a significant step towards establishing high-resolution X-ray microscopy as a standard investigation method for microscopic samples.

9.0K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

14.5K
The range is one of the measures of variation. It can be defined as the difference between a dataset's highest and lowest values. For example, in the study of seven 16-ounce soda cans, the filled volume of soda was measured, thus producing the following amount (in ounces) of soda:
15.9; 16.1; 15.2; 14.8; 15.8; 15.9; 16.0; 15.5
Measurements of the amount of soda in a 16-ounce can vary since different subjects record these measurements or since the exact amount - 16 ounces of liquid, was not...

02:29Hybrid Zones
22.0K
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...
