In Vivo Degradation Behavior of the Magnesium Alloy LANd442 in Rabbit Tibiae [PDF]

, 2011
In former studies the magnesium alloy LAE442 showed promising in vivo degradation behavior and biocompatibility. However, reproducibility might be enhanced by replacement of the rare earth composition metal "E" by only a single rare earth element ...

Optimizing casting process using a combination of small data machine learning and phase-field simulations

npj Computational Materials
It has been a challenge to employ machine learning (ML) to optimize casting processes due to the scarcity of data and difficulty in feature expansion. Here, we introduce a nearest neighbor search method to optimize the stratified random sampling in Latin

Oxidation behaviors of a Ni–Cr–W based superalloy with different microstructures

Journal of Materials Research and Technology
Oxidation behaviors of a Ni–Cr–W based superalloy were investigated in terms of microstructural characteristics. It was found that the specimens with small grains present a better oxidation resistance owing to their higher density of grain boundaries ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Strength modelling of Al-Cu-Mg Type alloys [PDF]

, 2006
Age hardening of Al-Cu-Mg type alloys occurs in two stages separated by a constant hardness plateau when the alloys are aged at 110°C to 240?C after solution treatment and quenching.

Deformation twinning in a nanocrystalline hcp Mg alloy [PDF]

, 2011
Nanocrystalline (nc) hexagonal close-packed (hcp) metals are rarely observed to deform by twinning, which is contrary to face-centered cubic metals. Here we report that, after alloying Mg with 10 at% Ti, deformation twins are observed in an nc Mg Ti ...

Phase-field modeling and Experimental investigation for rapid solidification in wire and arc additive manufacturing

Journal of Materials Research and Technology
The rapid solidification speed and significant temperature gradient observed in the wire and arc additive manufacturing (WAAM) process result in a deviation of the solid-liquid interface from the equilibrium state assumed by the conventional directional ...

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Antibacterial biodegradable Mg-Ag alloys

European Cells and Materials, 2013
The use of magnesium alloys as degradable metals for biomedical applications is a topic of ongoing research and the demand for multifunctional materials is increasing. Hence, binary Mg-Ag alloys were designed as implant materials to combine the favourable properties of magnesium with the well-known antibacterial property of silver. In this study, three
