Abstract Ruddlesden–Popper perovskite, (PEA) 2 PbBr 4 (PEA = C 8 H 9 NH 3 ), is a steady and inexpensive material with broad bandgap narrow‐band emission. These features make it potential candidate for deep‐blue light‐emitting diodes (LEDs). However, due to the weak exciton binding energy, LEDs based on perovskite thin films usually possess very low external quantum efficiency (EQE) of <0.03%. Here, first time, construction high‐performance 2D nanoplates (NPs) demonstrated. The...

The unstable PbSe quantum dot (QD) surface requires tedious and complicated synthetic protocols renders them substantially underdeveloped compared to PbS QDs. Here, we describe a direct synthesis of QD inks at room temperature. In comparison the conventional three-step synthesis, our strategy simplifies fabrication process one step reduces preparation cost by factor eight. A photovoltaic device based on these has achieved conversion efficiency (PCE) 10.38% with high stability, which is...

The versatility of somatosensation arises from heterogenous human dorsal root ganglion (DRG) neurons. critical information to decipher their functions, i.e., the soma transcriptome, is lacking due technical difficulties. Here we developed a novel approach isolate individual DRG neuron somas for deep RNA sequencing (RNA-seq). On average, >9000 unique genes per were detected, and 16 neuronal types identified. Cross-species analyses revealed that touch-, cold-, itch-sensing relatively...
