Atmospheric parameter sounding is a necessary input parameter and a reference for atmosphere and environmental protection departments to master the atmospheric conditions, conduct atmosphere and air quality forecasting and formulate corresponding emergency control strategies.
Nitrous oxide (N2O) and carbon monoxide (CO) play important roles in global warming. However, there are many difficulties in reliable long-time monitoring, especially for N2O, as the concentration of N2O in atmospheric is only a few hundred part per billion, while the compatibility precision is 0.1 part per billion recommended by World Meteorological Organization (WMO).
Organic-inorganic halide perovskite materials have excellent optical capture capacity and carrier conductivity. Perovskite solar cells, with amazing power conversion efficiency, show great application prospects.
A research team with the Hefei Institutes of Physical Science, Chinese Academy of Sciences reported their discovery that a metabolic regulation mechanism may play a role in malignant transformation of non-alcoholic steatohepatitis to liver tumor.
Constructing hot spots using their own properties can achieve sensitive and specific detection effects, but interrogating the optimal Surface Enhanced Raman Spectroscopy (SERS) hot spots is a great challenge for SERS detection of proteins.
