Exciton-Exciton Annihilation in Two-dimensional Halide Perovskites at Room Temperature

Recently, Ruddlesden–Popper 2D perovskite (RPP) solar cells and light-emitting diodes (LEDs) have shown promising efficiencies and improved stability in comparison to 3D halide perovskites. Here, the exciton recombination dynamics is investigated at…

Susceptibility to ABO and TBOA of LTD and extrasynaptic NMDAR-dependent tonic current in the aged rat hippocampus

Aging, as the major risk factor of Alzheimer's disease (AD), may increase susceptibility to neurodegenerative diseases through many gradual molecular and biochemical changes. Extracellular glutamate homeostasis and extrasynaptic glutamate N-Methyl-D…

Phase-sensitive amplification of an optical field using microwaves

We report phase-sensitive amplification (PSA) of a near-infrared electromagnetic field using room-temperature 85 Rb atoms possessing ground-state coherence. Our novelty is in achieving significant optical PSA by manipulating the intensity and phase…

Thermal phase fluctuations in optically pumped dual–frequency vertical external-cavity surface-emitting lasers for cesium clocks based on coherent population trapping

A fully analytical model is established for the thermal fluctuations of the beatnote phase of an optically pumped dual-frequency Vertical-External-Cavity Surface-Emitting Laser (VECSEL). This model starts with the resolution of the heat equation…

Bottom-up approach for the synthesis of grahene nanoribbons

The controlled synthesis of graphene nanoribbons (GNRs) is crucial to fully exploit their outstanding properties. Both the top-down and the bottom-up approaches were used to fabricate GNRs. In contrast to the top-down methods in which the GNRs are…

Hexacyano Ferrate (III) Reduction by Electron Transfer Induced by Plasmonic Catalysis on Gold Nanoparticles

Redox reactions are of great importance in environmental catalysis. Gold nanoparticles (Au-NPs) have attracted much attention because of their catalytic activity and their localized surface plasmon resonance (LSPR). In the present study, we…
