Dedicated TEM study from the core structure of adiabatic shear bands in dynamical deformed Ti6Al4V [PDF]

, 2010
Metals and alloys deformed at high strain rates, which are occurring during impact or metal forming situations can suffer from premature failure due to the introduction of so called adiabatic shear bands (ASB).

Strain localization in a shear transformation zone model for amorphous solids

, 2007
We model a sheared disordered solid using the theory of Shear Transformation Zones (STZs). In this mean-field continuum model the density of zones is governed by an effective temperature that approaches a steady state value as energy is dissipated.

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Age-dependent transient shear banding in soft glasses

, 2010
We study numerically the formation of long-lived transient shear bands during shear startup within two models of soft glasses (a simple fluidity model and an adapted `soft glassy rheology' model).

Formation of Stable Amorphous Calcium Phosphate and Collagen Assemblies by a Versatile Spray‐Drying Approach

Advanced Functional Materials, EarlyView.
Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.

Nanoindentation response of laser shock peened Ti-based bulk metallic glass

AIP Advances, 2015
The effect of laser shock peening (LSP) on mechanical properties of Ti-based bulk metallic glass (BMG) was investigated under nanoindentation. Two regions were generated within the specimen after the LSP: (I) the extremely thick softened region (∼300 µm)

Endothelial Cells Angiogenesis in Sulfated Glycosaminoglycan (GAG) Hydrogels Enhanced by Bioactive Glass‐Released Ions

Advanced Functional Materials, EarlyView.
A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...

Flow behavior at different shear rates for dry powders [PDF]

, 2010
Using Discrete Element Simulations (DEM), an effort is made to study the so called “Split bottom ring shear cell” where a slow, quasi-static deformation leads to wide shear bands.

Electron-Phonon mechanism for Superconductivity in Na$_{0.35}$CoO$_2$: Valence-Band Suhl-Kondo effect Driven by Shear Phonons

, 2006
To study the possible mechanism of superconductivity in Na$_{0.35}$CoO$_2$, we examine the interaction between all the relevant optical phonons (breathing and shear phonons) and $t_{2g}(a_{1g}+e_g')$-electrons of Co-ions, and study the transition ...
