News Chiral Lead-free Hybrid Perovskites Developed for Self-powered Circularly Polarized Light Detection
“The metal-halide perovskites feature the distinctive structure flexibility, which enables the employment of chiral organic cations to construct chiral perovskites. Such chiral perovskites are the promising alternative for circular polarized light (CPL) detection owing to their efficient charge transport of …
News Fatigue-free Layered Hybrid Perovskite Ferroelectric Developed for Photovoltaic Non-volatile Memories
“Ferroelectric materials with reversible spontaneous polarization have been extensively investigated as active media for non-volatile memories. However, most of the ferroelectric materials known suffer from high internal resistances, large bandgap, and poor carrier transportation, which hindered their further applications. The …
“Lithium metal batteries could double the amount of energy held by lithium-ion batteries, if only their anodes didn’t break down into small pieces when they were used. Now, researchers led by Prof. CUI Guanglei from the Qingdao Institute of …
News First Measurement Device Independent Quantum Key Distribution Experiment to Secure Communication
“PAN Jianwei and colleagues PENG Chengzhi and ZHANG Qiang, from University of Science and Technology of China of the Chinese Academy of Sciences (CAS), collaborating with WANG Xiangbin from Tsinghua University and YOU Lixing from Shanghai Institute of Microsystems of …
“Lithium is an energy-critical element that is considered to be a geopolitically significant resource. However, the supply of lithium may not be enough to meet continuously increasing demand. As a result, scientists are looking for new ways to extract lithium …
“Researchers from CAS Key Laboratory of Quantum Information of the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences have demonstrated on-demand storage of photonic qubits in an integrated solid-state quantum memory for the first …
“Machine learning is an important branch in the field of artificial intelligence. Its basic idea is to build a statistical model based on data and use the model to analyze and predict the data. With the rapid development of big …
“The freezing of water is one of the most common processes. However, understanding the microstructure of ice and its hydrogen-bonding networks has been a challenge. The low-energy structure of water octamer is predicted to be nominally cubic, with eight tri-coordinated …
“The Insight-HXMT team has performed extensive observations of the accreting X-ray pulsar GRO J1008-57 and has discovered a magnetic field of ~1 billion Tesla on the surface of the neutron star. This is so far the strongest magnetic field …
“An international team discovered that compressing monocrystalline (TaSe4)2I can create a system where the constituent TaSe4Q1D atomic chains are in amorphous state without breaking the orientational and periodic translation symmetries of the chain lattice. Moreover, they found that along …
