Large Scale Synthesis of Red-Emitting Quantum Dots for Efficient and Stable Light-Emitting Diodes.

Adv Mater

December 2024

Department of Applied Biology and Chemical Technology and Research Institute for Smart Energy, The Hong Kong Polytechnic University (PolyU), Hung Hom, Hong Kong, P. R. China.

It is known that large-scale synthesis of emitters affords colloidal quantum dot (CQD) materials with a great opportunity toward the mass production of quantum dot light-emitting diodes (QLEDs) based commercial electronic products. Herein, an unprecedented example of scalable CQD (> 0.5 kilogram) is achieved by using a core/shell structure of CdZnSe/ZnSeS/CdZnS, in which CdZnSe, ZnSeS, and CdZnS alloys are used as the inner core, transition layer and outermost shell, respectively.

Shanghai Key Laboratory of Forensic Medicine, Shanghai Forensic Service Platform, Academy of Forensic Sciences, Key Laboratory of Forensic Science, Ministry of Justice, Shanghai, China.

The human microbiome, the community of microorganisms that reside on and inside the human body, is critically important for health and disease. However, it is influenced by various factors and may vary among individuals residing in distinct geographic regions. In this study, 220 samples, consisting of sterile swabs from palmar skin and oral and nasal cavities were collected from Chinese Han individuals living in Shanghai, Chifeng, Kunming, and Urumqi, representing the geographic regions of east, northeast, southwest, and northwest China.

Department of Emergency, Kweichow Moutai Hospital, Zunyi 564500, Guizhou, China. Corresponding author: Zhou Manhong, Email:

Objective: To investigate the protective effect and possible mechanism of sulforaphane (SFN) on acute liver injury in mice induced by diquat (DQ) poisoning.

Methods: Forty-eight male C57BL/6 mice were divided into Control group, DQ model group (DQ group), SFN intervention group (DQ+SFN group), and SFN control group (SFN group) using a random number table method, with 12 mice in each group. Acute liver injury mice model was established by one-time intraperitoneal injection of 1 mL of 40 mg/kg DQ solution at once.

There is still potential room for improving the effectiveness of standard Cognitive Behavioral Therapy (CBT) in preventing the onset of depression, achieving full remission, and preventing relapse or recurrence of depression. Standard CBT seems less effective in reducing depressive rumination, a key risk factor leading to the onset and persistence of depression. To improve treatment efficacy for depression, rumination-focused cognitive behavioral therapy (RFCBT) was developed, which was modified from CBT and specifically targeted to manage rumination.

Alzheimer's disease (AD) is a neurodegenerative disease, which is mainly characterized by the abnormal deposition of β-amyloid peptide (Aβ) and Tau. Since Tau aggregation is more closely associated with synaptic loss, neurodegeneration, and cognitive decline than Aβ, the correlation between Tau and cognitive function in AD has gradually gained attention. The posttranslational modifications (PTMs) of Tau are key factors contributing to its pathological changes, which include phosphorylation, acetylation, ubiquitination, glycosylation, glycation, small ubiquitin-like modifier mediated modification (SUMOylation), methylation, succinylation, etc.
