Structural Performance of Hybrid Fiber–Metal Laminates Reinforced With Natural and Synthetic Fibers: Tensile, Dynamic–Mechanical, and Residual Stress Behavior

Polymer Composites, EarlyView.
Hybrid fiber‐metal laminates combining aluminum with carbon, glass, and sisal/epoxy layers. Sisal fibers maintained strength, improved strain and thermal stability, and reduced residual stresses with less synthetic fiber. ABSTRACT This work studied how hybridization between natural and synthetic fibers influences the structural tensile performance ...

4D imaging of a porous carbonate rock under triaxial loading: quantitative correlation between local porosity and strain

Journal of Synchrotron Radiation
The study of the mechanical behaviour of carbonate rocks has benefited from the evolution of experimental tools, due to their complex multi-scale microstructure.

Recycling of Thermoplastic Unidirectional Tapes: An Image‐Analysis Method for Measuring Residual Glass‐Fiber Length in Convoluted Fiber Clusters

Polymer Composites, EarlyView.
Development of a rapid, low‐cost method for measuring residual glass fibre length: samples are collected by tweezers, prepared via submersion, imaged with a flatbed scanner as a cost‐effective alternative to microscopy, and analyzed for fibre length independently of image acquisition.

Technique for bone volume measurement from human femur head samples by classification of micro-CT image histograms

Annali dell'Istituto Superiore di Sanità, 2013
INTRODUCTION: Micro-CT analysis is a powerful technique for a non-invasive evaluation of the morphometric parameters of trabecular bone samples. This elaboration requires a previous binarization of the images. A problem which arises from the binarization

Analyzing the compressive behavior of porous Ti6Al4V by X-ray microtomography [PDF]

Materials Research, 2017
Samples with 40% vol. of pores and a pore size distribution between 100 and 500 µm were produced by powder metallurgy from Ti6Al4V alloy powders. Sintering was performed at 1300 °C during one hour in an inert Argon atmosphere in a vertical dilatometer ...

Isothermal Reduction Behavior and Microstructural Evolution of Iron Ore Sinter Under Simulated Radial Blast Furnace Gas Atmospheres With Hydrogen Injection

steel research international, EarlyView.
Commercial iron ore sinter is reduced isothermally under operation‐derived radial blast furnace gas atmospheres with and without 20 kg H2/tHM injection. Hydrogen improves reduction at 900–1100 °C, whereas at 700 °C the high H2O content limits the wüstite‐to‐iron driving force.

How the Build Angle Affects the Marginal and Internal Fit of 3D Printed Definitive FPDs: An in Vitro Study

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Statement of Problem Printing parameters may influence the fit of additively manufactured dental restorations. However, the effect of small incremental build angles on the marginal and internal fit of stereolithography (SLA)‐printed definitive 3‐unit fixed partial dentures (FPDs) has not been sufficiently investigated.

Proportions des tissus des dents déciduales chez deux individus de Dordogne (France) : l’enfant néanderthalien du Roc de Marsal et le spécimen du Paléolithique supérieur final de La Madeleine.

Bulletins et Mémoires de la Société d’Anthropologie de Paris, 2008
Recent advances in the application to the human fossil record of high-resolution microtomographic analytical techniques allow the noninvasive quantitative characterization of the inner dental structure. Compared to the extant human condition, Neanderthal

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 ...
