Rationalizing the Unexpected Inefficiencies of 3D Porphyrin‐MOFs as Singlet Oxygen Photosensitizers Against Botrytis cinerea

open access: yesAdvanced Materials Interfaces, EarlyView.
Unexpected results show that the singlet‐oxygen based antifungal activity of porphyrin‐based Metal‐Organic Frameworks is far below expectations while the standalone ligand is more efficient. We attribute these behaviours to inefficient exciton migration and gas diffusion leading to low singlet oxgyen concentrations at and beyond the MOF‐gas interface ...

Versatile Silicon‐Based Surface‐Enhanced Raman Spectroscopy Chip for Quantitative Sensing and Point‐of‐Care Applications

open access: yesAdvanced Materials Interfaces, EarlyView.
This study fabricates highly sensitive, uniform SERS substrates scalable to wafer level. The dual‐function substrates integrate high‐density hot spots and spectral references for accurate quantitative detection, achieving 10⁻¹2 M BPE sensitivity (<5% deviation). Their application in monitoring urinary caffeine citrate for preterm infant apnea treatment

Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

open access: yesAdvanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.

Numerical and Experimental Study of High‐Speed Laser Cutting of Copper Current Collectors: Process Optimization for Quality Assessment

open access: yesAdvanced Materials Technologies, EarlyView.
This study employs a CFD model to simulate laser cutting of copper current collectors used for Li‐Ion battery production. This model predicts cut edge quality by assessing the influence of power, scanner speed, and foil thickness. Defects are classified and an optimal working area is found.

Transcript Identification Using Arrayed Hydrogels With TrapFISH

open access: yesAdvanced Materials Technologies, EarlyView.
TrapFISH is a novel method for high‐throughput single‐cell transcriptomics. It embeds cells in hyaluronic acid hydrogel beads and uses probe hybridization to quantify custom gene panels. By arraying hydrogels in microfluidic devices, cell barcoding is removed, enhancing scalability for studying cellular heterogeneity and rare cell states by targeting ...
