Multi‐scale Engineered Vasculature and Hierarchical Porosity via Volumetric Bioprinting‐Guided Photopolymerization‐Induced Phase Separation

open access: yesAdvanced Materials, EarlyView.
Vascularization in bioprinted hydrogels is limited by nanoscale porosity in hydrogel bionks. Volumetric bioprinting of gelatin–norbornene phase‐separating hydrogels permits to create centimeter‐scale constructs featuring interconnected multi‐scale porosity. Light dose gradients result in spatially controlled pore dimensions. Capillary‐scale vessels are

Wet‐Chemical Etching of Silicon Wafer Surfaces Using Aqueous HF‐HBrO3 and HF‐HBrO3‐Br2 Solutions

open access: yesAdvanced Materials Interfaces, EarlyView.
Aqueous mixtures of HF and HBrO3 are reported as a new NOx‐free etching systems for monocrystalline silicon wafers. Silicon is polished with etching rates up to 10 µm min−1 at room temperature. The addition of Br2 leads to anisotropic etching, thus texturing monocrystalline silicon wafer surfaces with upright pyramids.

Structural Self‐Healing Superhydrophobic Surfaces: Healing Mechanisms, Methods, and Future Challenges

open access: yesAdvanced Materials Interfaces, EarlyView.
Superhydrophobicity can be restored by repairing damaged micro/nanostructures via mechanisms like particle reorganization, polymer swelling, shape memory effects, and reversible dynamic bonds. This structural recovery is typically initiated by stimuli including heat, light, solvent exposure, or through autonomous self‐healing processes.
