Satellite-free droplet formation in material jetting via rheology-driven waveform modelling approach

Materials & Design
Stable, satellite-free droplet ejection is essential for high-resolution material jetting (also known as 3D inkjet printing). Existing “printability windows” often fail to predict satellite formation accurately, as they neglect non-Newtonian fluid ...

A Microphysiological Interface of Skeletal Myobundles and Inflamed Adipose Tissue for Recapitulating Muscle Dysfunction in an Obese Microenvironment

Advanced Healthcare Materials, EarlyView.
A human cell‐based microphysiological system integrates engineered muscle tissues with an inflamed adipose–macrophage niche to model obese microenvironment‐induced muscle dysfunction. Muscle contraction is quantified by pillar deflection coupled with computational stiffness estimation. Secretome and transcriptomic profiling reveal inflammation‐mediated
