Near-infrared spectroscopy (NIRS) is a rapid and non-destructive spectroscopic analytical technique that can play an important role in in the fields of food production and crop breeding. Data fusion technology is a framework containing methods and tools to combine data from different sources, which has received a lot of attention in recent years.
On Dec.26, Long March-4C carrier rocket was successfully launched. Together with it were three sets of metallic damping components for orbit HD optical imaging satellite. They will help to deal with the strong-vibratory shock damage and micro-vibratory interference in the control moment gyro (CMG) of high-definition satellite during rocket launch and in-orbit operation.
The certified power conversion efficiency (PCE) of Organic-inorganic hybrid perovskite solar cells can exceed 25.5% currently. However, stability remains the dominating obstacle in practical applications as it’s easy to degrade when exposed in air. Scientists have been trying to make the device stable, better with self-healing properties that can resist hostile operation environments.
Neutron, as an electrically neutral particle, has a strong penetrability and always emits secondary gamma rays during the particle collision process. The scientific and efficient scheme of shielding neutron is to select high Z (atomic number), low Z materials, and neutron absorbing materials simultaneously for combined shielding. However, lead-containing materials are restricted in application with biological toxicity.
1,056 seconds, a new pulse length world record for high temperature tokamak plasma has been achieved on the "artificial sun" in Institute of Plasma Physics, Hefei Institutes of Physical Sciences (HFIPS), Chinese Academy of Sciences (ASIPP). On December 30th, the experimental advanced superconducting tokamak (EAST) set this milestone of tokamak operation for longer than 1,000 seconds by the end of 2021.
