  • Characterization of Thermal Conductivity of Half-Heusler Materials.png
    Scientists Explore Characterization of Thermal Conductivity of Half-Heusler Materials

    Thermoelectric material is one kind of functional materials which can directly convert heat into electricity. Understanding the factors that affect the thermal conductivity is a topic of great scientific interest, which will guide to reduce the lattice thermal conductivity or search materials with low lattice thermal conductivity. Recently, researchers from Institute of Solid State Physics, Hefei Institutes of Physical Science, constructed two concise parameters in characterization of thermal conductivity of half-Heusler compounds.

    Researchers Investigate the Structure of Phosphate Ionic Conducting Glasses Using Solid-state NMR

    Currently, the doping of transition metal ions in phosphate glasses has attracted wide attention since the transition metal ions can significantly modify electrical conductivity and optical properties of glasses. The addition of alkali halide might further promote the mobility of ions. Most recently, a research team led by Shanghai Institute of Optics and Fine Mechanics has investigated the structures of MoO3-doped phosphate ionic conducting glasses in detail using multiple solid-state NMR technologies.

  • Distinct Processing of lncRNAs Contributes to Non-conserved Functions in Stem Cells

    A research team led by Dr. CHEN Lingling from Center for Excellence in Molecular Cell Science, Shanghai Institute of Biochemistry and Cell Biology of the Chinese Academy of Sciences, discovered that distinct processing of lncRNA orthologs resulted in different subcellular localization in human and murine embryonic stem cells (ESCs). This subsequently leads to their functional divergence in the context of pluripotency regulation across species.

    Milk Production Declines Due to Heat Stress in Northern China

    Northern China is a major dairy-producing region in the country. However, milk production is expected to drastically decline by 2050, with losses potentially up to 50% by 2070, because of heat stress in July, says a new study conducted by a team of scientists from the Kunming Institute of Botany.
