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

open access: yesPolymer 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 ...

Phase contrast imaging with a laboratory-based microfocus X-ray source [PDF]

open access: yes, 2007
This project looks at the design of an in-line X-ray phase contrast imaging system, based around the Bede Microsource®, on a suitable scale for imaging small pathological samples. The system is applied to two test objects to assess feasibility of its use

Neutron microtomography of voids in gold

open access: yesMethodsX, 2017
Pilot attempt of the neutron microtomography of voids in gold carried out using the Neutron Microscope instrument is presented in the paper. The paper demonstrates that neutron microtomography provides viable alternative to X-ray imaging for the ...

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

open access: yesPolymer 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.

X-ray microtomography in herpetological research: a review - Supplementary material

open access: yes, 2018
Herpetological research, like any other (palaeo)biological science, relies heavily on accurate data collection, particularly visualisation and quantification of anatomical features.

Multi-Analytical Approach for Asbestos Minerals and Their Non-Asbestiform Analogues: Inferences from Host Rock Textural Constraints

open access: yesFibers, 2019
The analytical protocol included optical microscopy (OM), scanning and transmission electron microscopy combined with energy dispersive spectrometry (SEM/EDS; TEM/EDS), micro-Raman spectroscopy and synchrotron radiation X-ray microtomography (SR X-ray ...

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

open access: yessteel 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

open access: yesJournal 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.

Microfocus X-ray imaging of Brazil nuts for quality control

open access: yesSemina: Ciências Agrárias, 2015
Non-destructive quality assessment of food prior to processing is desirable in commercial facilities due to its non-invasive nature, for economic reasons and for its safety appeals. Grading Brazil nuts in this way allows for the separation of undesirable

Anatomical description of the jaw muscles and theoretical bite force assessment in South American opossums using manual and digital dissection methods

open access: yesJournal of Anatomy, EarlyView.
Manual and virtual dissections were employed to examine the masticatory muscle architecture and bite force of three South American marsupials. The organisation of the muscles differed between species, with predicted bite forces exceeding previous estimates.
