Advanced Materials Interfaces, EarlyView.SAA significantly enhanced Al/PU bonding, increasing SLSS by up to 920% and fracture energy by 15 100% through optimized micro‐nano porous surfaces. RSM identified the optimal anodizing conditions, while ML confirmed sulfuric acid concentration and roughness as dominant predictors of strength.

Self‐Assembled Fluorescent Nanodiamond Layers for Quantum Imaging
Advanced Materials Interfaces, EarlyView.We developed a simple, scalable method for coating surfaces with fluorescent nanodiamonds. By optimizing the coating process, we created uniform, dense layers that enable high‐resolution magnetic imaging using the nitrogen‐vacancy (NV) center in nanodiamonds. This approach enables the development of cost‐effective quantum‐sensing and imaging substrates

Nanoporous Microelectrodes for Neural Electrophysiology Recordings in Organotypic Culture
Advanced Materials Technologies, EarlyView.The highly porous microelectrodes have been designed and printed on culture membranes, allowing to record electrophysiological neural activity for rodent brain slices. To keep the biocompatible nanoporous structure, the microelectrodes and insulative layer are fabricated on the bottom of culture membranes with only small connector pads added on the top.
