Researchers from Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS) proposed an optimized synthesis strategy recently to obtain defect-free low-layer M4C3Tx (M = V, Nb, Ta) MXene nanosheets successfully.
According to a work recently published in Matter, a collaborated team led by Prof. YANG Zhaorong and Prof. Hao Ning from High Magnetic Field Laboratory, Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS), found that quasi-one-dimensional charge density wave (CDW) material CuTe under high pressure is a rare and promising platform for studying multiple CDW orders and superconductivity (SC).
Based on density functional theory analysis, the research team led by Prof. ZHENG xiaohong proposed that the double barrier structure can greatly enhance the tunneling electroresistance (TER) of ferroelectric tunnel junctions (FTJs), and demonstrated that the double barrier ferroelectric tunnel junction (DB-FTJ) can realize multi-state storage.
Recently, a research group lead by Prof. Peng Tong from the Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), discovered a novel NTE material and synthesized a Cu2P2O7/2024Al composite with zero thermal expansion (ZTE). It has a high specific thermal conductivity and strong machinability, and it improves the negative thermal expansion (NTE) impact of Cu2P2O7 substantially.
Nuclear power systems contain many complex sequence failure behaviors due to standby redundant designs. Performing the risk assessment of sequence failure behaviors using dynamic fault trees can identify potential weaknesses of the nuclear power system so that preventive and mitigation measures can be effectively taken to improve the safety and economy of nuclear power plants.
