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.
Recently, researchers from the Institute of Solid State Physics, Hefei Institutes of physical science of Chinese Academy of Sciences revealed the Zener relaxation in the body-centered cubic (BCC) Fe-Ga single crystals against intuition originates primarily from the stress-induced reorientation of the second-nearest-neighbor Ga-Ga atom pairs.
Recently, a research group led by Prof. HAN Yuncheng from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), along with Prof. XIONG Houhua from Hubei University of Science and Technology, proposed a new 99Mo production design.
Recently, Prof. HUANG Qunying’s research team from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) developed a novel inorganic silica-based adsorbent for the highly selective separation of strontium from acidic medium in collaboration with Prof. NING Shunyan’s team from the South China University.
