Three-dimensional distribution of primary melt inclusions in garnets by X-ray microtomography [PDF]

, 2018
open6X-ray computed microtomography (X-mu CT) is applied here to investigate in a non-invasive way the three-dimensional (3D) spatial distribution of primary melt and fluid inclusions in gamets from the metapeitic enclaves of El Hoyazo and from the ...

Microstructure–Mechanical Response Relationship in Discontinuous Fiber‐Reinforced SMC Composites: Damage Mechanisms

Polymer Composites, EarlyView.
Architecture of SMC composites. ABSTRACT The mechanical performance of sheet molding compounds (SMCs) is dependent on microstructural characteristics determined by material composition and processing conditions. The study investigates standard SMCs, advanced SMCs (A‐SMCs), and low‐density SMCs (LD‐SMCs) under quasi‐static and fatigue loading to ...

Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils

THREE DIMENSIONAL CHARACTERIZATION OF SOIL MACROPOROSITY BY X-RAY MICROTOMOGRAPHY

Revista Brasileira de Ciência do Solo, 2015
Analysis of the soil pore system represents an important way of characterizing soil structure. Properties such as the shape and number of pores can be determined through soil pore evaluations. This study presents a three-dimensional (3D) characterization

Non‐Destructive Inspection of TCPs Using Pulse‐Echo Ultrasound and X‐Ray Microcomputed Tomography Techniques

X-Ray Spectrometry, EarlyView.
ABSTRACT Thermoplastic composite pipes (TCPs) have potential applications in offshore oil and gas industries because of their strength, lack of corrosion, and flexibility. Designed for fluid transportation in high‐pressure and high‐temperature environments, manufacturing defects and operational loads can compromise their performance.

Pore-scale contact angle measurements at reservoir conditions using X-ray microtomography

, 2014
Contact angle is a principal control of the flow of multiple fluid phases through porous media; however its measurement on other than flat surfaces remains a challenge.

Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope

Integrative Zoology, EarlyView.
The polygamous mating system of the orb‐web spider genus Argiope provides a model to study the evolution of sperm transfer under morphological and behavioral constraints. This helps us to understand how male and female behavioral and morphological reproductive traits influence sperm transfer.
