The purest 520! We’re giving you perovskite QLED with the highest EQE efficiency!
Owing to their exceptional color purity, perovskite quantum-dot–based light-emitting diodes (QLEDs) hold great promise for future solid-state lighting and high-definition displays. However, charge imbalance during device operation can lead to charge accumulation, which in turn causes luminescence quenching and severely degrades device performance. Researchers led by Song Jizhong at Nanjing University of Science and Technology have reported a green-light perovskite QLED that exhibits both high color purity and high efficiency and stability.

OLED Classic Training Materials
Introduction to OLED Display Technology OLED (Organic Light-Emitting Diode), also known as organic electroluminescent display or organic light-emitting semiconductor, is the English abbreviation for organic light-emitting diode. It is a device that generates electroluminescence through a multilayer organic thin-film structure. Its ease of fabrication and low driving voltage make OLED particularly well-suited for flat-panel display applications. Compared with LCDs, OLED displays are lighter and thinner, offer higher brightness, lower power consumption, faster response times, superior image clarity, greater flexibility, and higher luminous efficiency.

Peng Qiang and Yan He’s EES: 17.33% Efficiency! High-Efficiency Non-Fullerene Organic Solar Cells
Over the past several decades, organic photovoltaics (OPV) have attracted considerable research attention. The recent emergence of polymer solar cells based on non-fullerene acceptors has significantly advanced the field of OPV. However, high-performance polymer solar cells to date are typically fabricated using halogenated solvents. These halogenated solvents pose risks to human health and the environment and are therefore unsuitable for industrial applications. Moreover, due to the limited solubility of non-halogenated solvents, it is challenging to achieve the desired morphological control, which in turn hinders their adoption in practical applications.

Zhou Huanping, Joule: Record Efficiency of 25.2%! High-Efficiency Perovskite Solar Cells (at −53°C)
Mixed-halide perovskite solar cells have been found to hold potential applications beyond terrestrial use, owing to their unique advantages in cold environments. Unfortunately, the pioneering technology is limited in device efficiency, and the underlying operational mechanisms at low temperatures remain unclear.

Professor Zhang Qiang of Tsinghua University in Chem: A New Breakthrough in Electrolytes for Sodium-Metal Anodes!
【Research Background】 Lithium (Li) and sodium (Na) metal batteries have attracted considerable attention due to their high energy density. Compared with lithium metal batteries, sodium batteries benefit from abundant resources and lower costs, making them promising for large-scale energy storage applications. However, unlike conventional carbon anodes, metallic sodium exhibits high reactivity and a propensity for dendrite formation, thereby imposing more stringent requirements on the electrolyte used.

JACS: Computational Simulation Study of the Stability and Optoelectronic Properties of MAPbI3 Material
Exposure of CH3NH3PbI3 perovskite materials to oxygen and light reduces their chemical stability. In light of this, Long Run and colleagues at Beijing Normal University reported a study on CH3NH3PbI3 that investigated the relationships among its degradation behavior, carrier lifetime, and the oxidation states of oxygen species.
The Function and Principle of Vacuum Tubes in Automobiles
There are two types of vacuum tubes in the vehicle: one is used for the brake booster, and the other for the distributor’s ignition advance mechanism. Their function is to supply vacuum to one side of the booster diaphragm while allowing the other side to communicate with the atmosphere. In this way, the atmospheric pressure on the diaphragm pushes the pushrod forward, thereby providing power assistance.

Another RMB 1.6 trillion has been injected—how far is Northeast China from revitalization?
Recently, with the issuance by the National Development and Reform Commission of the Three-Year Rolling Implementation Plan for Revitalizing Northeast China and Other Old Industrial Bases (2016–2018) (hereinafter referred to as the “Plan”), the revitalization of the Northeast economy has once again become the focus of attention across society. In particular, the provision in the Plan that “the state will invest RMB 1.6 trillion in the Northeast” has sparked intense public debate.

A 4,000 km/h train is on the way—running inside a vacuum tube.
To attend the Third China (International) Commercial Aerospace Summit in Wuhan from Beijing, the reporter took the high-speed rail, a 1,152-kilometer journey that took just over four hours. At the summit, a reporter from Science and Technology Daily learned that China Aerospace Science and Industry Corporation is advancing a “High-Speed Flying Train” project that could reduce the Beijing–Wuhan trip to under half an hour.
