Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

open access: yesAdvanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Counterion‐Controlled Photocatalytic Doping of Organic Semiconductors

open access: yesAdvanced Materials, EarlyView.
Counterion size is shown to actively control photocatalytic doping in organic semiconductors. Small anions suppress aggregation of acridinium photocatalysts, enhance electron transfer, and dramatically increase doping efficiency. This simple strategy enables conductivities up to 2000 S cm−1 in benchmark polymers, revealing counterions as a powerful yet

Insights Into Degradation Pathways of Perovskite Thin Films under Outdoor and Indoor Conditions: A Comparative Analysis

open access: yesAdvanced Optical Materials, EarlyView.
This study compares indoor low‐light and outdoor high‐light degradation in perovskite thin films. Under ∼1000 lux [N2], films remain stable; in oxygen, the same low light triggers strain, surface oxidation, and shorter lifetimes. Whereas high light accelerates decomposition to PbI2 and metallic oxides.

Multi-boson simulation of the Schroedinger functional

open access: yes, 1997
We discuss the choice of parameters and report some results for unquenched simulations of the Schroedinger functional with a non-hermitean variant of Luescher's multi-boson algorithm.Comment: Contribution to Lattice 97 (Edinburgh), 7 pages (single column,

Nanocrystal Quality–Controlled Scintillation in Porous YAG:Ce Aerogels

open access: yesAdvanced Optical Materials, EarlyView.
High‐temperature thermal treatment of YAG:Ce nanoscintillator aerogels increases light yield under ionizing radiation by up to eightfold without affecting timing performance. Additionally, low‐temperature atmospheric treatments reversibly modify the cerium oxidation state, revealing strong defect sensitivity and offering new strategies to optimize ...
