Theoretical characterization of a model of aragonite crystal orientation in red abalone nacre

open access: yes, 2009
Nacre, commonly known as mother-of-pearl, is a remarkable biomineral that in red abalone consists of layers of 400-nm thick aragonite crystalline tablets confined by organic matrix sheets, with the $(001)$ crystal axes of the aragonite tablets oriented ...

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...
