Ultralow Loading Iridium Doped Hollandite Manganese Oxide Nanowires for Efficient Acidic Oxygen Evolution Reaction

Advanced Materials, EarlyView.
Ultralow iridium loading in hollandite MnO2 nanowires delivers an order of magnitude higher Ir mass activity than commercial IrOx for acidic water oxidation. Across pH and potential, Ir stays framework‐associated while Mn reconstructs, yet the most restructured catalyst is not the most dissolved, indicating that dissolution alone is an incomplete ...

Reduced Graphene Oxide Enhances the Vascular Organization and Contractile Performance of Fibrin‐Gelatin‐Based Engineered Cardiac Tissue

Advanced Materials Interfaces, EarlyView.
Fibrin–gelatin hydrogels functionalized with reduced graphene oxide create a mechanically stable and bioactive 3D environment for engineered cardiac tissue. The composite matrix promotes endothelial lumen formation, enhances sarcomeric protein expression, and increases contractile performance of embedded cardiomyocytes.

Control of Bacterial Attachment on Macroporous PDMS/Paraffin SLIPS With Varying Lubricant Viscosity

Advanced Materials Interfaces, EarlyView.
Slippery liquid‐infused porous surfaces (SLIPS) prepared from macroporous PDMS, infused with medical‐grade paraffins, were systematically investigated regarding the correlation of viscosity, surface corrugation, bulk porosity, and bacterial resistance. Substrate porosity was found to dominate lubricant stabilization and the antifouling activity.

The Virtual Element Method on Anisotropic Polygonal Discretizations

, 2019
In recent years, the numerical treatment of boundary value problems with the help of polygonal and polyhedral discretization techniques has received a lot of attention within several disciplines. Due to the general element shapes an enormous flexibility is gained and can be exploited, for instance, in adaptive mesh refinement strategies.

High Throughput Aerosol Jet Printing to Operationalize High Aspect Ratio Patterning

Advanced Materials Technologies, EarlyView.
High‐throughput aerosol jet printing poses distinct limiting mechanisms to the printing process. These include rapidly changing ink chemistries, atomization instabilities, and liquid‐phase spreading. The combination of in‐line heating, process monitoring, and traditional optimization procedures enables rapid printing of high‐aspect‐ratio structures ...

3D Printed Photon Shield Assembly for Low‐Noise Visual Stimulation During Two‐Photon Imaging in Mice

Advanced Materials Technologies, EarlyView.
We present the Photon Shield, an open‐hardware system for low‐noise two‐photon calcium imaging during visual stimulation in mice. Combining a 3D‐printed headplate and rail‐mounted shield substantially reduces stray‐light contamination, as quantitatively verified. Functional validation confirms reliable cortical responses. Open design files enable broad
