Diketopyrrolopyrrole‐Based Cation as a Semiconducting Spacer in Layered Perovskite
Advanced Materials, EarlyView.Diketopyrrolopyrrole cation incorporated layered perovskites exhibiting extended absorption profiles and enhanced charge carrier mobility with type‐II energy alignment. The improved photoconversion efficiency demonstrates the critical role of incorporating organic semiconductors in optimizing layered perovskite performance.

Defect‐Templated Phase Engineering in Atomically Thin Metals
Advanced Materials, EarlyView.Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

Ion Concentration and Voltage Imaging With Fluorescent Nanodiamonds
Advanced Materials, EarlyView.We demonstrate reversible switching between the fluorescent NV0 and the dark NV+ state, in sub‐30 nm FNDs via surface oxidation and hydrogenation, respectively. In an electrochemical cell, we show that the fluorescence from hydrogenated particles enables all‐optical imaging of voltages and ion concentrations at the micrometer scale.

All‐Amyloid Functional Coacervates
Advanced Materials, EarlyView.This study introduces an all‐amyloid interfacial complex coacervate technique that employs charge‐mediated or functionalization‐assisted complexation of oppositely charged food protein‐derived amyloid nanofibrils to engineer functional soft constructs across multiple length scales.

Dependence of photoluminescence induced by carbon contamination on GeSi structure
, 1998 We studied the dependence of photoluminescence induced by carbon contamination on the Ge/GeSi structure. It is found that a carbon and silicon defect complex may be formed in a special structure by opening the in situ high-energy electron diffraction ...

Advanced Materials, EarlyView.Alkoxy chain length drives a continuous transition from eclipsed AA to a serrated, slipped AA* configuration over Co‐porphyrin COFs. A moderate slip both contracts the pore channel to enrich CO2 and suppress hydrogen evolution, and enhances collective high‐spin of Co sites, which delivers a record CO production rate with high selectivity.

Moldavian Journal of the Physical Sciences, 2019 The kinetics of a strongly nonequilibrium state of electrons and holes excited in quantum dots by a long laser pulse in the p-states are studied using time-resolved photoluminescence. Three bands of the transient photoluminescence spectra are identified,
