Controlling Ultrafast Photonic‐Plasmonic Coupling in a Hybrid Platform for Biosensing Applications
Advanced Optical Materials, EarlyView.A metal–dielectric hybrid composed of gold nanocaps on opal exhibits a broad near‐infrared plasmonic resonance interacting with the photonic bandgap under ultrafast transient conditions. This coupling can be controlled by varying the excitation wavelength and is responsive to bacterial deposition, opening new opportunities for ultrafast biosensing ...

, 2022 Digital signatures are widely used in recent times by organisations public and private alike. Similar to fingerprints the signatures are legally binding. Another reason why they are being used is that they are easy to handle and store. The digital signatur es are utilised mainly in ecommerce websites for delivery authentication to the customers, bank ...

Space Group Modulated Upconversion and Mechanoluminescence in [YbEu] Cocrystal Complexes
Advanced Optical Materials, EarlyView.We report here a space group regulation strategy to optimize both upconversion and mechanoluminescence in cocrystal assemblies, representing the first example of integrating these two properties within a single lanthanide complex material. ABSTRACT Lanthanide complexes exhibiting stimuli‐responsive luminescence, such as upconversion (UC) and ...

Thermally Induced Creep and Viscoelastic Behavior of Copper Micropillar Arrays
Advanced Science, EarlyView.Copper micropillar arrays are fabricated by electrodeposition within through‐glass‐via, and their thermally induced time‐dependent deformation is quantified. Nanoindentation creep, EBSD, and TEM reveal a heat‐treatment‐driven transition between grain‐boundary‐mediated deformation and dislocation‐dominated creep, while Kelvin modeling captures ...
