A Comparative Study on Microstructure, Segregation, and Mechanical Properties of Al-Si-Mg Alloy Parts Processed by GISS-HPDC and SEED-HPDC. [PDF]

Materials (Basel), 2023
There are multiple routes to prepare semi-solid slurries with a globular microstructure for semi-solid forming. The variations in the microstructure of semi-solid slurries prepared using different routes may lead to significant differences in the flow behavior and mechanical properties of rheo-diecasting parts.

Synchronizing the Osteochondral Regeneration Process through Spatial Patterning of Stable and Hypertrophic Cartilage Organoids. [PDF]

Adv Mater
Zonated osteochondral assembloid implants are engineered through scaffold‐free spatial assembly of induced pluripotent stem cell (iPSC)‐derived chondrocyte organoids and periosteum‐derived osteogenic organoids. Implanted into full‐thickness rat osteochondral defects, they promote hyaline‐like cartilage repair, support subchondral bone formation with ...

Enzymatic Basis for the Oxidative Branch of Aromatic Amino Acid Fermentation Leading to p-cresol Formation. [PDF]

Adv Sci (Weinh)
In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...
