Development of a Synthetic 3D Platform for Compartmentalized Kidney In Vitro Disease Modeling
Advanced Healthcare Materials, EarlyView.A fully synthetic, compartmentalized 3D kidney disease model is introduced. The kidney model combines a PEG‐based hydrogel matrix with anisotropic, enzymatically degradable rod‐shaped microgels to spatially arrange a triple co‐culture of key renal epithelial, endothelial, and fibroblast cells.

Advanced Healthcare Materials, EarlyView.A 3D biomimetic OS model was developed by bioprinting an OS‐cell‐derived dECM‐enriched bioink with OS spheroids incorporated. The model showed upregulation of known OS prognostic markers and increased resistance to doxorubicin, compared to 2D cultures and scaffold‐free spheroids, making this a more clinically relevant platform for drug discovery ...

Study of the costs and benefits of composite materials in advanced turbofan engines [PDF]
Composite component designs were developed for a number of applicable engine parts and functions. The cost and weight of each detail component was determined and its effect on the total engine cost to the aircraft manufacturer was ascertained.

Advanced Healthcare Materials, EarlyView.A bioassembly approach is described using photo‐crosslinked gelatin‐based microgels containing calcium peroxide (CaO2) to generate oxygen (O2) and enhance cell survival in hypoxic conditions (1% O2). Bioassembly enables spatial patterning of individual CaO2‐laden and mesenchymal stem cell (MSC)‐laden microgels and allows for decoupling and mitigating ...

Manufacturing processes for fabricating graphite/PMR 15 polyimide structural elements [PDF]
Investigations were conducted to obtain commercially available graphite/PMR-15 polyimide prepreg, develop an autoclave manufacturing process, and demonstrate the process by manufacturing structural elements. Controls were established on polymer, prepreg,

Advanced Healthcare Materials, EarlyView.3D printed hybrid scaffolds combining bioactive silica–calcium chemistry with elastic polymers guide human bone stem cells to form bone. The scaffolds support cell survival, organization, and invasion while releasing osteogenic ions. Together, architecture and composition drive bone‐specific gene expression, extracellular matrix organization, and ...
