Six group standards for the commercial specifications and grades of Chinese herbal medicines, issued under the Anhui Provincial Association of Chinese Materia Medica, have been released. The team led by researcher Li Xiangxian at the Anhui Institute of Optics and Fine Mechanics (AIOFM) was among the principal drafting units, covering Peucedanum root, Clinopodium herb, Atractylodes macrocephala root, Moutan bark, red peony root, and white peony root. The standards classify grades primarily by morphological characteristics and active ingredient content. The team applied the advantages of Fourier transform infrared spectroscopy - rapid, nondestructive, and multicomponent detection - to the quality evaluation of Chinese herbal medicines, and demonstrated mid-infrared and portable near-infrared FTIR analyzers.

The spaceborne High-precision Main Greenhouse gas Imaging instrument (HMI) aboard the Pujiang-4 satellite began imaging on September 27 and downlinked its first data. The developer team led by Xiong Wei at the Anhui Institute of Optics and Fine Mechanics (AIOFM) performed a preliminary assessment and found that the payload's functions and performance met design requirements. HMI uses an information modulation technique combining spatial imaging and spectral interferometry, acquiring hyperspectral data in a 520 km orbit with a 30 km swath, spatial resolution better than 400 m, and spectral resolution better than 0.125 nm. From the first data, the team preliminarily estimated the methane emission rate of the Bogatyr open-pit mine in Kazakhstan at about 27.52±1.70 tons per hour.
Why we recommend it: The original article gives HMI's swath, spatial resolution and spectral resolution, and uses first data to estimate methane emissions from a mining area, showing the on-orbit performance of the combined spatial imaging and spectral interferometry approach
