Atmospheric conditions vary significantly in terms of the temporal and spatial scales. The purpose of atmospheric correction based on radiative transfer model is to remove the atmospheric radiative effect on remote sensing images, but it is always limited by the difficulty in obtaining atmospheric parameters that match image in terms of the temporal and spatial scale.
Recently, a research team led by Professor GAO Xiaoming from Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science of Chinese Academy of Sciences developed a new type of spectrometer which is capable of simultaneous remote sensing of atmospheric CH4, H2O and N2O.
Recently, a research team led by associate Prof. XU Zhenyu from Hefei Institutes of Physical Science, Chinese Academy of Sciences suggested a new method to detect atmospheric greenhouse gas column with high-resolution laser heterodyne spectroscopy.
Light, electric field, alternating magnetic field, and pH have been used as triggers to boost the release of pesticide, among which the pH-responsive type attracts broad interest due to simple operation and low cost. Albeit this, most of pH-controlled pesticides exhibit monotonic response to acid or alkali, and thus the large-scale application is limited, since pH of water for agricultural spraying may vary between weakly acidic and weakly alkaline among places. To meet this challenge, it is strategic to devise acid/alkali dual pH-responsive controlled-release pesticides that are flexible in multiple application situations.
Recently, the research team led by associate Prof. GE Daochuan from Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS) reported their new findings in the field of risk assessment methods and applications of spent fuel transportation.
