Amidation-Retarded Synthesis of Perovskite Quantum Dots with Low Defect Density and Enhanced Carrier Transport for Efficient Light Emitting Diodes and Solar Cells.

Perovskite quantum dots (PQDs) are promising for both solar cells (SCs) and light emitting diodes (LEDs) for their excellent optoelectronic characteristics and solution-processable fabrication. One of the general limitations for these two kinds of devices is that high defect density and poor charge transport, resulting from the unavoidable amidation-induced PbX precipitation at high reaction temperature. In this work, an amidation-retarded synthesis strategy is proposed to prevent the PbX precipitation and subsequent defect formation.

TOP-Zn Steric Hindrance Effect Enables Ultra-Uniform CsPbX Quantum Dots for Wide-Color Gamut Displays.

The impact of core training combined with breathing exercises on individuals with chronic non-specific low back pain.

Background: Chronic non-specific low back pain (CNLBP) is a common condition, defined as pain lasting more than 3 months between the lower thoracic margin and gluteal folds, without identifiable tissue damage. Despite its low disability rate, the complex etiology and high recurrence impose significant health and socioeconomic burdens. According to European LBP guidelines, exercise therapy is the preferred treatment for CNLBP.

Controllable Transition Metal Cations Doping Enable Efficient and Spectral Stable Pure-Red Perovskite QLED.

Mixed-halide perovskite plays important role in wide-color gamut displays as a vital material for three primary colors. However, halide segregation and caused unstable spectra are the intrinsic problem in mixed-halide perovskite light-emitting diodes (PeLEDs) originating from the lattice strain and the resulting defects in perovskite quantum dots (PQDs). Here, smaller transition metal cations are applied to replace Pb and release lattice strain, which avoids halogen escaping/halide vacancies forming to ensure high photoluminescence quantum yield (PLQY) and stable spectra.

Fine Purification Engineering Enables Efficient Perovskite QLEDs with Efficiency Exceeding 23.

Perovskite quantum dots (PeQDs) have great application prospects in fields such as displays and solar cells due to their adjustable band gap, high absorption coefficient, high carrier mobility, and solution processability. However, the ionic crystal characteristic of PeQDs and their surface ligands have led to problems such as solvent sensitivity, poor crystal stability, and difficulty in adjusting the photoelectric properties, which are challenges in high-quality PeQDs. Here, to solve the problem of fluorescence degradation caused by phase change and loss of surface ligands during the purification process of CsPbI QDs, this work develops a purification strategy that finely regulates the polarity of the purification solvent, to obtain high-purity perovskite.

Indirect purification method provides high yield and quality ssDNA sublibrary for potential aptamer selection.

The quality and yield of single-stranded DNA (ssDNA) play key roles in ssDNA aptamer selection. However, current methods for generating and purifying ssDNA provides either low yield due to ssDNA loss during the gel purification process or low specificity due to tertiary structural damage of ssDNA by alkaline or exonuclease treatment in removing dsDNA and by-products. This study developed an indirect purification method that provides a high yield and quality ssDNA sublibrary.
