“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 …
“Due to the wide application of photodetectors in the fields including optical communication, environmental monitoring, and image sensing, the research for developing highly efficient photodetectors has attracted extensive attention over the past decades. Since 2009, methyl ammonium lead halide (CH3NH3PbX3 …
“Conventional wide-field microscopy (WFM) cannot provide optical sectioning (OS) images that are required for 3D volumetric reconstruction. The reason lies in the fact that the out-of-focus signals are always coupled within the in-focus plane. By introducing structured illumination microscopy (SIM …
“By tuning the direction of the external magnetic field with respect to the crystallographic axis of the silicon wafer, an improvement of spin lifetime (relaxation time) by over two orders of magnitude was reported in silicon quantum dots (QDs). This …
“The exchange of a ‘secret key’ for encrypting and decrypting messages over a distance of 1,120 kilometres is reported in Nature this week. This achievement is made using entanglement-based quantum key distribution, a theoretically secure communication technique. Previous attempts …
