Additive Manufacturing of Alumina‐Reinforced Elastomers

open access: yesAdvanced Engineering Materials, EarlyView.
Vat‐photopolymerized elastomers reinforced with platelet‐shaped alumina exhibited preferential orientation, reduced porosity, and significantly enhanced mechanical performance. A 3 wt% platelet loading increased tensile strength from 12.4 to 45.7 MPa, highlighting the critical role of filler morphology in elastomeric VPP composites.

Nature and Artificiality: in Search of a lost Harmony

open access: yesAgathón, 2017
Maghreb’s desert, an eternal landscape of slow and irrational creation, or the Motya’s Salterns, geometrical landscape, logical and violent. Both landscapes capture our attention: the desert enhances nature, it is not susceptible to enduring changes and ...

Semantic Modeling in Materials Science and Engineering With Platform MaterialDigital Core Ontology 3.0

open access: yesAdvanced Engineering Materials, EarlyView.
The community‐driven Platform MaterialDigital Core Ontology (PMDco) 3.0 is introduced as a Basic Formal Ontology‐aligned semantic backbone for the processing–structure–properties paradigm in Materials Science and Engineering. Modular engineering, automated releases, and validation workflows are highlighted and key semantic patterns for materials ...

Baidu’s perfect paradox : free speech and the right to censor [PDF]

open access: yes, 2014
China’s biggest search engine has a constitutional right to filter its search results, a US court found last month. But that’s just the start of the story.\ud \ud Eight New York-based pro-democracy activists sued Baidu Inc in 2011, seeking damages ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

The characters of prince Myshkin by F.M. Dostoyevsky and Jeshu Ha-Nocri by M.A. Bulgakov : (an attempt at typological comparison)

open access: yesOpera slavica, 2013
The typological correlation of the "perfect heroes" in the novels "Idiot" by F. Dostoyevsky and "Master and Margarita" by M. Bulgakov manifests itself on several levels: the thematic one (the metaplot about the advent in the word of a "positively perfect

Enhanced Ultrasound Transmission Through Aberration Layers Using Space‐Coiling Acoustic Metamaterials

open access: yesAdvanced Engineering Materials, EarlyView.
Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

In perfect synchrony: tubulin

open access: yes, 2013
Presents an early embryonic divisions in Drosophila are syncytial. Nuclei undergo mitosis synchronously for the first 14 nuclear cycles, followed by cellularization (Foe and Alberts, 1983).
