3D Printable Magnetic Soft Actuators–Ink Formulation, Rheological Characterization, and Hydrogel Actuator Prototypes

Macromolecular Materials and Engineering
Magnetic inks are presented for direct ink writing (DIW), a 3D printing technique, yielding magnetic hydrogel actuators. To obtain the shear‐thinning and thixotropic behavior needed for DIW, the rheology modifier laponite is used.

Structural Guidance in 3D Microgel‐in‐Hydrogel Systems to Improve Chondrogenesis

Advanced Healthcare Materials, Volume 15, Issue 29, 7 August 2026.
The Anisogel, an anisotropic microgel‐in‐hydrogel system, guides chondrogenic differentiation of human mesenchymal stromal cells (hMSCs) modulated by the alignment and size of anisometric microgels. Chondrogenic markers are upregulated in an in vitro model and guided tissue infiltration is enhanced in a semi‐orthopedic mouse model due to the physico ...

Modeling and Analysis of Nonlinear Radiative and Electromagnetic Effects With Second‐Order Slip in Unsteady Hybrid Nanofluid Flow Past a Porous Stretching Surface

Engineering Reports, Volume 8, Issue 8, August 2026.
The current work examines the dynamics of the stagnation point flow of an unsteady hybrid nanofluid (Fe2O3–Cu/H2O) across an inclined porous stretching surface. It considers heat transfer, second‐order slip, electrical field, heat source/sink, mixed convection, and magnetic field effects, as well as linear and nonlinear radiation.

Biocompatible, 3D Printable Magnetic Soft Actuators – Ink Formulation, Rheological Characterization and Hydrogel Actuator Prototypes

Macromolecular Materials and Engineering
3D printable inks for the preparation of magnetic hydrogel actuators are difficult to formulate because magnetic nanoparticles tend to aggregate without stabilization through other ink components. At the same time, such inks need to be shear‐thinning and
