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

Advanced 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

Overlapping Nanostacks Enable Direct Printing of Organic LEDs

Advanced Materials Interfaces, EarlyView.
The capability of laser‐induced forward transfer (LIFT) for the additive fabrication of a complex thin‐film multilayer OLED device is demonstrated. The process, with precisely fabricated layer thicknesses in the nanometer range and high quality interfaces with low surface roughness, yielded fully functional OLEDs showing stable electroluminescence. The

Enhancing Grayscale E‐Beam Lithography: Thermal Treatment of Novolak‐Based Resist for 3D Nanostructures

Advanced Materials Interfaces, EarlyView.
Surface roughness and chemistry of novolak‐based grayscale resists are dependent on both exposure dose and post‐exposure thermal treatment. The observed trends align with the viscoelastic phase separation model and underscore the need to consider both thermodynamic and kinetic factors in resist processing. By tailoring thermal treatment, it is possible

Quasielastic Neutron Scattering Reveals Anisotropic Water Transport in Smectite Thin Film

Advanced Materials Interfaces, EarlyView.
Clay minerals, vital in advanced technologies, exhibit tunable interfacial properties. Quasielastic neutron scattering is used on oriented beidellite films to study charge‐induced anisotropy. Results reveal anisotropic water dynamics and orientation‐dependent diffusion.
