A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Measurement of three-dimensional stress field of RP model having a notch by using digital holography

open access: yesEPJ Web of Conferences, 2010
We measure three-dimensional stress field of RP model having a V-notch. RP model (Elastic modulues E = 3317 MPa, 9.3 × 7.7 × 50 mm3 having a V-notch) is made of acrylic transparent resin and tracer particle (averaged diameter: 60μm) are dispersed.

Grain Refinement During Severe Plastic Deformation and Similitude of Subgrain Formation: A Molecular Dynamics Study

open access: yesAdvanced Engineering Materials, EarlyView.
Molecular dynamics is used to investigate structure refinement during severe plastic deformation. The results show similitude with experimental data. Molecular dynamics simulations of severe plastic deformation of monocrystalline and polycrystalline samples by multiaxial compression of aluminum are carried out.

An investigation into how the cell cycle and the Notch signalling pathway regulate pronephrogenesis in Xenopus laevis [PDF]

open access: yes
The connections between cell cycle exit and terminal differentiation remain poorly understood. Cyclin dependent Kinase Inhibitors (CKIs) provide a possible link between entry into the quiescent state and differentiation.

Advanced Electron Microscopy and Microcomputed Tomography Analysis of Single‐Crystal Ni‐Base Superalloys After Short‐Term Multiaxial Creep

open access: yesAdvanced Engineering Materials, EarlyView.
This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Notch Signaling In Solid Tumors

open access: yes
In recent years a substantial body of evidence derived from not only preclinical but also clinical studies has accumulated in support of Notch signaling playing important oncogenic roles in several types of cancer.

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Canonical Notch Signaling in the Developing Lung Is Required for Determination of Arterial Smooth Muscle Cells and Selection of Clara Versus Ciliated Cell Fate

open access: yes, 2011
Lung development is the result of complex interactions between four tissues: epithelium, mesenchyme, mesothelium and endothelium. We marked the lineages experiencing Notch1 activation in these four cellular compartments during lung development and ...
