Solution-Processed Green and Blue Quantum-Dot Light-Emitting Diodes With Eliminated Charge Leakage
Nature Photonics, 2022 Quantum-dot light-emitting diodes (QD-LEDs) promise a new generation of efficient, low-cost, large-area, and flexible electroluminescent devices. However, the inferior performance of green and blue QD-LEDs is hindering the commercialization of QD-LEDs in display and solid-state lighting. Here, we demonstrate best-performing green and blue QD-LEDs with ~

Laparoscopic Management of Chylous Leakage Using a Direct Lymph Node Injection With Methylene Blue as a Leakage Point Location Strategy in a Patient With Retroperitoneal Extragonadal Seminoma [PDF]
Journal of Endourology Case Reports, 2018 Background: The first-line treatment in cases of chylous leakage is conservative, and operation should be considered only in patients who fail to respond to this treatment. The main clinical concern is the difficulty of intraoperative localization of the site of leakage that can affect surgical outcome.

An Evaluation of the Effect of Methylene Blue Dye pH on Apical Leakage
Journal of Endodontics, 1993The effect of varying the pH of 2% methylene blue dye on apical leakage was evaluated. Eighty-four roots of extracted human teeth were used in this study. The roots were endodontically cleaned and shaped, obturated, apically resected, and amalgam or Temporary Endodontic Restorative Material retro-fillings were placed. The roots were immersed for 7 days

Evans blue (EB) is the most widely used tracer to assess BBB leakage. However, a well-established method to obtain visualized and quantitative results of EB extravasation is presently unavailable.We reported a novel method to quantify BBB leakage by combining EB and high molecular weight FITC-Dextran (2000 kDa).

Electron leakage is one of the most critical factors for the degradation of blue fluorescent organic light‐emitting diodes (FOLEDs), as it occurs when electrons injected from the cathode flow to an electron‐blocking layer (EBL) without being entirely consumed within an emissive layer (EML). To address this issue, this study introduces the concept of an

Carrier Leakage in Blue‐Green II–VI Semiconductor Lasers
Applied Physics Letters, 1995Carrier confinement in blue-green II–VI semiconductor lasers was investigated. For devices longer than 300 μm an energy barrier of 260–280 meV was found to confine the electrons, the carrier being mainly responsible for leakage, within the active region.

Complete suppression of surface leakage currents in microperforated blue light-emitting diodes
Applied Physics Letters, 2009We investigated the effects of thermal annealing and sulfide passivation on the electrical characteristics of GaN-based light-emitting diodes (LEDs) whose active regions were integrated with a plasma-etched microhole array resembling a photonic crystal structure. Thermal annealing removed most plasma damage in the near-surface bulk region, whereas (NH4)

Study on the light leakage mechanism of a blue phase liquid crystal cell with oblique interfaces
Journal of Physics D: Applied Physics, 2012Abstract The mechanism of light leakage in the dark state of a blue phase liquid crystal display cell which has protruded electrodes was investigated. We have performed a hybrid numerical simulation by combining the geometrical optics with the extended Jones matrix method.
