Analysis of the Internal Anatomy of Distal Root Canals of Mandibular Molars: A Micro‐Computed Tomography Study

X-Ray Spectrometry, EarlyView.
ABSTRACT Detailed knowledge of the internal anatomy of the root canal system and its variations is essential for selecting appropriate endodontic treatment protocols. Micro‐computed tomography (micro‐CT) allows for nondestructive, high‐resolution three‐dimensional (3D) analysis of extracted teeth, enabling precise evaluation of root canal morphology ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

About the Ageing‐Induced Modifications of Physical‐Chemical and Electrical Properties of Polyimide (PMDA‐ODA) Under Gamma Radiation and High Temperatures

High Voltage, EarlyView.
ABSTRACT This study investigates the effects of radiation‐induced ageing on the physical, chemical, mechanical and electrical properties of Poly[4,4′‐oxydiphenylene‐ pyromellitimide] (PMDA‐ODA) polyimide, a high‐performance insulation material widely used in aerospace applications.

Research on Nonuniform Ageing State Assessment of Oil‐Immersed Power Transformers Based on PCA–GWO–RF Algorithm

High Voltage, EarlyView.
ABSTRACT The condition assessment of oil–paper insulation is critical for oil–immersed power transformers, which are fundamental to the reliability of modern power systems. The primary limitation of traditional transformer ageing assessment lies in its macroscopic, whole‐unit approach, which fails to account for the localised effects of nonuniform ...

Evolution of hierarchical phase‐contrast tomography on the European Synchrotron beamlines BM05 and BM18: a whole adult human brain imaging case study

Journal of Synchrotron Radiation, EarlyView.
The evolution of hierarchical phase‐contrast tomography (HiP‐CT) from its origins at the BM05 beamline to its transition to BM18 (ESRF‐EBS) is shown. The novel hardware and scanning approach developments resulted in significantly improved data quality, resolution, sensitivity and speed.
