Vibronic effect and influence of aggregation on the photophysics of graphene quantum dots

Graphene quantum dots, atomically precise nanopieces of graphene, are promising nanoobjects with potential applications in various domains such as photovoltaics, quantum light emitters or bio-imaging. Despite their interesting prospects, precise…

Exciton Cooling in 2D Perovskite Nanoplatelets: Rationalized Carrier-Induced Stark and Phonon Bottleneck Effects

Using femtosecond transient absorption (fs-TA), we investigate the hot exciton relaxation dynamics in strongly confined lead iodide perovskite nanoplatelets (NPLs). The large quantum and dielectric confinement leads to discrete excitonic transitions…

Bioimpedance single cell sensing of low and high density sickle erythrocytes using microfluidics

In this paper, sickled red blood cells of different densities from distinct Sickle Cell Disease (SCD) patients were analyzed, using a microfluidic device based on bioimpedance sensing. Complementary to our previous work (Xu et al., 2020)…

Synthesis and optical properties of rod-shaped graphene nanoparticles

The scientific community has given much interest to graphene in recent years because of its good mechanical, thermal and electrical properties. Nonetheless, applications in optics and optoelectronics can be limited due to the absence of a bandgap…

DM1 Transgenic Mice Exhibit Abnormal Neurotransmitter Homeostasis and Synaptic Plasticity in Association with RNA Foci and Mis-Splicing in the Hippocampus

Myotonic dystrophy type 1 (DM1) is a severe neuromuscular disease mediated by a toxic gain of function of mutant RNAs. The neuropsychological manifestations affect multiple domains of cognition and behavior, but their etiology remains elusive…
