Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Ultrafast Intermolecular Dynamics of Nanoconfined Water in Swollen Lipid Cubic Mesophases

open access: yesSmall, EarlyView.
Terahertz absorption spectroscopy reveals the temperature‐dependent intermolecular dynamics and structure of water in topologically distinct bicontinuous cubic lipid mesophases. Atomistic simulations show increased hydrogen‐bond disruption with heating and enable quantification of interfacial water, which correlates positively and nonlinearly with ...

Room‐Temperature Collective Quantum Emission Mediated by Wannier–Mott Excitons in CsPbBr3 Nanowires

open access: yesSmall Science, EarlyView.
Room‐temperature collective quantum emission emerges in partially aligned CsPbBr3 nanowires through spontaneous synchronization of Wannier–Mott excitons. This alignment enables cooperative dipole–dipole interactions that result in coherent photon bursts (N2 × hν), even under ambient conditions.
