Determination Techniques for Hydroxyl and Hydroperoxyl Radicals in the T...


Description
 
This study focuses on the determination methods of hydroxyl (OH) and hydroperoxyl (HO₂) free radicals in the atmosphere and troposphere, which play crucial roles in atmospheric oxidation processes and pollutant degradation. Various detection techniques—such as laser-induced fluorescence (LIF), chemical ionization mass spectrometry (CIMS), and peroxy radical chemical amplification (PERCA)—are evaluated for their sensitivity, precision, and environmental applicability. The review also highlights methodological advances, intercomparison campaigns, and challenges in measuring low-concentration radicals under ambient conditions, contributing to a better understanding of atmospheric chemical dynamics and climate interactions

  Ex-Google engineer joins Shanghai robotics start-up to take lead on advanced AI research A pre-eminent  Google  scientist, Luo Jianlan, has joined Chinese humanoid  robotics  company  AgiBot , known on the mainland as Zhiyuan, to lead the  Shanghai -based  start-up ’s new  artificial intelligence  (AI) research centre. Known as a leading scholar in AI and robotics, Luo will spearhead the establishment of the Zhiyuan Embodied Intelligence Research Centre as the newly appointed chief scientist of AgiBot, a start-up co-founded in 2023 by former  Huawei Technologies  “Genius Youth” recruit  Peng Zhihui . Luo has closely collaborated with renowned computer scientist Sergey Levine, a co-founder of San Francisco-based AI start-up Physical Intelligence. He previously worked at Google’s “moon shot factory” Google X and AI research lab Google DeepMind. Luo – who obtained his doctoral degree from the University of California, Berke...

Scientists Monitor Surface Solar Radiation

  Scientists monitor surface solar radiation via satellite remote sensing BEIJING -- A geostationary satellite network observation (GSNO) system has been developed to precisely monitor changes in surface solar radiation by introducing satellite remote sensing technology, according to the Aerospace Information Research Institute (AIR) under the Chinese Academy of Sciences. Serving like a "sunlight scanner," the GSNO system can provide more precise data support for sectors such as clean energy application, agricultural yield estimation and climate change response, as well as public health, said the institute. The study was led by AIR researchers and conducted in collaboration with researchers from multiple institutions, both at home and abroad. The study results have been published in the journal The Innovation. Surface solar radiation is a general term for the solar radiation components received by the Earth's surface, including ultraviolet rays, visible light, infrared an...

Brain-Computer Interface Technology

  China advances in brain-computer interface technology, aiming for US$900 per procedure A Chinese brain-computer interface (BCI) company said it had seen positive results from three human implants, matching Elon Musk’s Neuralink in the number of human patients, as China prepares for wider commercialisation of the technology. Beinao No 1, a semi-invasive BCI system developed by the Chinese Institute for Brain Research (CIBR) in Beijing and its affiliated start-up NeuCyber NeuroTech, completed their first three human implants between February and March this year, the companies said last week. The Chinese government, meanwhile, is moving to support the market for BCI products, which are inching closer to commercialisation. The local government in China’s central Hubei province on Monday released the country’s first pricing guidelines for the operation, stipulating that invasive BCI implants should cost 6,552 yuan (US$902) per procedure, and that the price of removal should be 3,139 y...
