Advanced Science, EarlyView.A smart power‐generating coating is developed to harvest energy from both ambient humidity and impacting liquid droplets. The integrated system delivers sustained open‐circuit voltages of 0.85 V from moisture and up to 36 V from droplets. Its scalable coating architecture enables a continuous power supply for low‐power electronic devices.

Angewandte Chemie, EarlyView.Titanium silicalite‐1 (TS‐1), used in industrial selective oxidation processes, depends on specific, yet still unresolved Ti sites, dispersed within the framework of an MFI‐zeolite. Applying high field (28.2 T) 47/49Ti NMR and 17O NMR spectroscopy for an array of TS‐1 catalysts enables the development of an NMR crystallography protocol and the ...

Advanced Science, EarlyView.ABSTRACT The combination of metasurfaces with chalcogenide phase‐change materials is a highly promising route toward the development of multifunctional and reconfigurable nanophotonic devices. However, their transition into real‐world devices is hindered by several technological challenges. This includes, amongst others, the lack of large area photonic

The interplay between dopants and oxygen vacancies in the magnetism of V-doped TiO2
, 2011 Density functional theory calculations indicate that the incorporation of V into Ti lattice positions of rutile TiO2 leads to magnetic V4+ species, but the extension and sign of the coupling between dopant moments confirm that ferromagnetic order cannot ...
