Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Ultra‐Flexible µ‐ECoG Arrays Based on PEDOT:PSS Micropillars
This work demonstrates an efficient procedure for fabricating ultra‐flexible neural interfaces endowed with micropatterned microelectrodes to increase surface area and characterized by extremely low impedance values to enable high‐quality recordings. The home‐built device has been shown to record somatosensory evoked potentials in vivo with exceptional

Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials
This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

Mechanisms by which excitons and charge carriers can funnel and recombine in 2D multi‐layered MAPbBr3 Ruddlesden‐Popper perovskite nanosheets are missing. This femtosecond transient absorption spectroscopy study creates a comprehensive understanding of how directed transport, exciton‐exciton annihilation, and Auger recombination occur in colloidal ...

Abstract Recent global events and the rise of sustainable investing have made clear that the chemical and energy industry must consider sustainability goals beyond profit maximization to remain competitive. Multiobjective optimization provides an ideal framework for analyzing sustainability tradeoffs, but when four or more objectives are considered ...

For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

Bright and Stable Electrochemiluminescence by Heterobimetallic IrIII‐MI (MI = CuI, AuI) Complexes
Bright and stable electrochemiluminescence (ECL) of a new class of heterobimetallic ionic transition metal complexes is triggered in the presence of the coreactant n‐tri propylamine (TPrA) upon highly energetic electron transfer (eT). A quantum efficiency (ΦECL) up to six‐fold higher than that of benchmark tris‐(2,2′‐bipyridyl) ruthenium(II) is ...
