Embedding Fiber Segment Interferometry for Localization of Defects in Composite Structures

Polymer Composites, EarlyView.
Graphical representation of composite structures with embedded fiber optic sensors for structural health monitoring, enabling strain measurement and damage localization under mechanical loading. ABSTRACT In the area of structural health monitoring (SHM), embedding strain sensors into smart composites is a key strategy for detecting failures arising ...

Critical Review of Brazil Disk Techniques for Tensile Strength Characterization With an Emphasis on High Explosive Materials

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Mechanical properties are a critical performance metric for many high explosive (HE) materials and tensile strength properties are particularly important. Direct tensile measurements using dogbone shaped samples are the gold standard but they have the disadvantage that they are fairly large and require samples machined from billets.

Real-Time Detection of Human Growth Hormone Based on Nanoporous Anodic Alumina Interferometric Biosensor

Sensors
Human growth hormone (hGH) is a polypeptide hormone that is synthesized and secreted by the anterior pituitary gland, whose excess is linked to acromegaly-causing pituitary adenomas while deficiencies are linked to disorders including short stature and ...

Anticlastic Curvature and Material Freedom

physica status solidi (b), EarlyView.
Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.

Roughness Measurements at Small and Uneven Surfaces of Ceramic Foam Filters

Surface and Interface Analysis, EarlyView.
ABSTRACT This study investigated the possibility of roughness characterization of ceramic foam filters using a laser scanning microscope, examining the influence of magnification, measured area, cutoff wavelength (λc), measured roughness parameter, and position within the ceramic foam on the measured roughness data. Firstly, the effect of magnification

The Impact of Dust Particles on the Function of Screen‐Printed Triple‐Mesoscopic Perovskite Solar Cells

Small, EarlyView.
Screen‐printed mesoporous carbon perovskite solar cells offer an accessible route to scalable green energy. This study investigates the impact of dust particle contamination during the manufacture of this type of solar cell. Results suggest clean rooms may be unnecessary if strict cleanliness is maintained during storage and printing processes in ...

Influence of Heat Treatment Temperature on Crevice and Pitting Corrosion of UNS S32205 Duplex Stainless Steel

steel research international, EarlyView.
Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

The Influence of Different Polishing Systems on the Gloss and Surface Roughness of Two Distinct Nano‐Filled Composites

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the influence of different polishing systems on the surface roughness and gloss of two nano‐filled resin composites, and to investigate the effect of a modeling agent (Ceramage) on surface roughness. Methods Two nano‐filled resin composites, Filtek Z350 XT and Palfique LX5, were used.

Application of Noise2Inverse and adaptation (Noise2Phase) to single‐mask x‐ray phase contrast micro‐computed tomography

Journal of Microscopy, EarlyView.
Abstract X‐ray phase contrast imaging (XPCI), when implemented in micro‐computed tomography (micro‐CT) mode, offers high‐contrast 3D imaging of weakly‐attenuating material samples. In the so‐called single‐mask edge illumination approach, a mask with periodically spaced transmitting apertures is used to split the x‐ray beam into narrow beamlets; when ...

Hyperspectral tomographic diffractive microscopy: Development and applications

Journal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...
