Water-Soluble Quantum Dots for Inkjet Printing Color Conversion Films with Simultaneous High Efficiency and Stability.

Water-soluble quantum dots (QDs) are necessary to prepare patterned pixels or films for high-resolution displays with less environmental burden but are very limited by the trade-off between photoluminescence and stability of QDs. In this work, we proposed synthesizing water-soluble QDs with simultaneous excellent luminescence properties and high stability by coating the amphiphilic poly(maleic anhydride--1-octadecene)-ethanol amine (PMAO-EA) polymer on the surface of silane-treated QDs. These coated QDs show a photoluminescence quantum yield (PLQY) as high as 94%, and they have good photoluminescence stability against light irradiation and thermal attacks, owing to the suppression of the nonradiative recombination by the polymer layer and the isolation of oxygen and water by the silica layer.

Organic Sulfonium-Stabilized High-Efficiency Cesium or Methylammonium Lead Bromide Perovskite Nanocrystals.

Herein, we report a new X-type ligand, i.e., organic sulfonium bromide, for high-efficiency CsPbBr and MAPbBr (MA=methylammonium) perovskite nanocrystals (PNCs).

LMO7-ALK Fusion in a Lung Adenocarcinoma Patient With Crizotinib: A Case Report.

Background: Rearrangements of the anaplastic lymphoma kinase (ALK) gene comprise a small subset of non-small cell lung cancer (NSCLC). Patients with NSCLC harboring ALK fusion proteins are sensitive to ALK tyrosine kinase inhibitors (TKIs). Various fusion partners of ALK are being discovered with the application of next-generation sequencing (NGS).

In Situ Inkjet Printing Patterned Lead Halide Perovskite Quantum Dot Color Conversion Films by Using Cheap and Eco-Friendly Aqueous Inks.

Inkjet-printed perovskite quantum dot (PQD) color conversion films (CCFs) have great potentials for mini/micro-LED displays because of their ultrahigh color purity, tunable emissions, high efficiency, and high-resolution. However, current PQD inks mainly use expensive, toxic, and flammable organic substances as solvents. In this work, water is proposed to be used as the solvent for inkjet printing PQD/polymer CCFs.

Inkjet-Printed Quantum Dot Color Conversion Films for High-Resolution and Full-Color Micro Light-Emitting Diode Displays.

Micro light-emitting diodes (μLEDs) have been considered an excellent candidate for next-generation display technology because of their promising optical properties, outstanding power efficiency, fast response time, high reliability, etc. However, the μLED displays based on individual red-green-blue (RGB) primary chips suffer from severe issues in mass production, such as difficulty in mass transfer, high cost, and low reproducibility. To overcome these issues, an alternative approach has been proposed to achieve full-color μLEDs by assembling ultraviolet- or blue-μLEDs with QD color conversion films (CCFs).

Functional polyaspartic acid derivatives as eco-friendly corrosion inhibitors for mild steel in 0.5 M HSO solution.

To improve the corrosion inhibition efficiency of eco-friendly polyaspartic acid (PASP) for mild steel in acidic solutions, PASP/-(3-aminopropyl)imidazole (PD-1) and PASP/-(3-aminopropyl)-imidazole--dodecylamine (PD-2) were chemically synthesized by the facile ring-opening reaction of polysuccinimide. Inhibition efficiencies of PD-1 and PD-2 for mild steel in a 0.5 M HSO solution were investigated by electrochemical measurements (electrochemical impedance and polarization) and the weight loss method.
