Bioactive glass-ceramic scaffolds from novel 'inorganic gel casting' and sinter-crystallization [PDF]

, 2017
Highly porous wollastonite-diopside glass-ceramics have been successfully obtained by a new gel-casting technique. The gelation of an aqueous slurry of glass powders was not achieved according to the polymerization of an organic monomer, but as the ...

Infant cortex responds to other humans from shortly after birth [PDF]

, 2013
A significant feature of the adult human brain is its ability to selectively process information about conspecifics. Much debate has centred on whether this specialization is primarily a result of phylogenetic adaptation, or whether the brain acquires ...

Increasing β-catenin/Wnt3A activity levels drive mechanical strain-induced cell cycle progression through mitosis. [PDF]

, 2016
Mechanical force and Wnt signaling activate β-catenin-mediated transcription to promote proliferation and tissue expansion. However, it is unknown whether mechanical force and Wnt signaling act independently or synergize to activate β-catenin signaling ...

Effect of La3+ Modification on the Electrochemical Performance of Na3V2(PO4)2F3

Batteries, 2018
La3+ modification of Na3V2(PO4)2F3 was performed by the direct mechanochemically assisted solid-state synthesis of the Na3V2−xLax(PO4)2F3 compositions, and by the LaPO4 coating of the as-prepared Na3V2(PO4)2F3 via the precipitation method.

Mechanical activation of vinculin binding to talin locks talin in an unfolded conformation [PDF]

, 2014
The force-dependent interaction between talin and vinculin plays a crucial role in the initiation and growth of focal adhesions. Here we use magnetic tweezers to characterise the mechano-sensitive compact N-terminal region of the talin rod, and show that

Dynamic interplay between defective UiO‐66 and protic solvents in activated processes [PDF]

, 2019
UiO-66, composed by Zr-oxide inorganic bricks [Zr-6(mu(3)-O)(4)(mu(3)-OH)(4)] and organic terephthalate linkers, is one of the most studied metal-organic frameworks (MOFs) due to its exceptional thermal, chemical, and mechanical stability.
