Screening Fluorination Additives for Efficient Perovskite Light-Emitting Diodes.

Fluorinated additives are proposed to address the issue of domain polydispersity in quasi-2D perovskites. However, the lack of established screening criteria for these additives necessitates a laborious and costly trial-and-error process. Herein, this work explores the behind nature for the first time how various fluorination in fluorinated additives affect domain distribution in quasi-2D perovskites.

Surficial Homogenic Effect Enables Highly Stable Deep-Blue Perovskite Light-Emitting Diodes.

The device performance of deep-blue perovskite light-emitting diodes (PeLEDs) is primarily constrained by low external quantum efficiency (EQE) especially poor operational stability. Herein, we develop a facile strategy to improve deep-blue emission through rational interface engineering. We innovatively reported the novel electron transport material, 4,6-Tris(4-(diphenylphosphoryl)phenyl)-1,3,5-triazine (P-POT2T), and utilized a sequential wet-dry deposition method to form the homogenic gradient interface between electron transport layer (ETL) and perovskite surface.

Efficacy and outcome of indocyanine green-based intraoperative cholangiography using near-infrared fluorescence imaging: A prospective study.

Introduction: The most dreaded complication during laparoscopic cholecystectomy still remains to be injury to the common bile duct. The primary cause for bile duct injury during LC is misinterpretation of the biliary anatomy. Intra-operative cholangiography was introduced as a means of reducing the chances of biliary injury, done using Fluoroscopic imaging or Near-infrared fluorescence imaging method.

Analysis of 'enhanced-view totally extra-peritoneal' (eTEP) approach for ventral hernia: Early results.

Introduction: Laparoscopic ventral hernia repair is undergoing a paradigm shift with the introduction of numerous new techniques to improve the outcomes. Enhanced-view totally extra-peritoneal (eTEP) is a novel approach for the repair of ventral herniae introduced by Belyansky et al. The key innovation lies in placing the mesh in a large retrorectus-pre-peritoneal space contrary to the widely practiced intra-peritoneal placement.
