Chemical Functionalization of 1H‐Mos2 for Programmed Modulation of Photoluminescence

open access: yesChemistryEurope, EarlyView.
Chemical functionalization of monolayer MoS2 via diazonium chemistry enables programmed modulation of photoluminescence. Electron‐donating groups suppress, while electron‐withdrawing groups enhance emission. Raman and cryo‐PL confirm defect‐free functionalization. Surface morphology shows nanometer thick films, and electrical measurements reveal trends

Enhanced Electroactivity for Overall Water Splitting and Oxygen Potential of Pt/Carbon Nanotubes Functionalized with Cu Organometallic Complex

open access: yesEnergy Technology, EarlyView.
Functionalizing carbon nanotubes (CNT) with the mesitylcopper (Cu‐mes) complex modifies the surface of CNT, developing Cu‐Pt alloys and Cu‐species. The result is a modified Pt electronic structure that promotes the catalytic activity of the 5 wt% Pt/CNTCu‐mes nanocatalyst for hydrogen and oxygen evolution reactions, and oxygen reduction reaction.

Cloaked Quasi Bound States in the Continuum in Semiconductor Metasurfaces with Out‐of‐Plane Symmetry Breaking

open access: yesLaser &Photonics Reviews, EarlyView.
The impact of out‐of‐plane symmetry breaking in semiconductor metasurfaces on bound states in the continuum (BICs) with vertical dipole‐like character is theoretically investigated. By tilting/inclining the meta‐atoms–thus effectively rotating the dipolar resonances–a so‐called cloaked quasi‐BIC is excited at a specific angle of incidence ...
