, 2016 Minimally Invasive Surgery (MIS) represents the gold standard in the majority of abdominal operations, although some fundamental limitations are still present and are far to be really addressed despite emerging robotic solutions. Flexible endoscopes can exploit their high flexibility to reach the surgical target while being inserted remotely or by a ...

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus
Advanced Functional Materials, EarlyView.The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...

Encoding Magnetic Anisotropies in Digital Light Processing 3D Printing
Advanced Functional Materials, EarlyView.A hybrid magnetic device—combining a coaxial coil within a nested Halbach array—is presented, integrated into a DLP 3D printer to enable spatially resolved magnetic field control. This system enables complex, multimodal responses by programming liquid crystal elastomer resins for magnetic and thermal actuation, and by inducing electrically conductive ...

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation
Advanced Functional Materials, EarlyView.This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Cardiac‐Derived ECM Microspheres for Enhanced hiPSC‐CMs Maturation
Advanced Functional Materials, EarlyView.Cardiac extracellular matrix microspheres derived from decellularized porcine heart provide a biomimetic 3D microenvironment for human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CMs). This platform supports short‐ and long‐term culture, enhances structural organization, and promotes electrophysiological and functional maturation of ...

Digital Actuation Control of Soft Robotic Origami With Self‐Folding Liquid Crystal Elastomer Hinges
Advanced Functional Materials, EarlyView.Self‐folding soft‐rigid hybrid robotic origami is enabled by liquid crystal elastomer actuators with embedded Joule heating and closed‐loop digital control. Digitally addressable hinges provide reversible and programmable transitions between distinct folded states while maintaining actuation performance at high cycle counts (over 1500).

3D printing with a 3D printed digital material filament for programming functional gradients
Nature CommunicationsAdditive manufacturing, or 3D printing attracts growing attention as a promising method for creating functionally graded materials. Fused deposition modeling (FDM) is widely available, but due to its simple process, creating spatial gradation of diverse ...

Advanced Functional Materials, EarlyView.It is elucidated that phase engineering of cobalt modulates the interfacial potential gradients of cobalt–carbon electrocatalysts, enhancing the intrinsic electrocatalytic performance. Modulating the dominant crystalline phase of cobalt from a hexagonal close‐packed to a face‐centered cubic enriches the electron density of carbon shells, thereby ...
