一 |     8月6日，2026年“博物馆之城”主题篆刻作品展在中国印学博物馆开展。作为该馆连续三年倾力打造的品牌特色展览，本次作品展秉持匠心，特邀西泠印社社员潜心创作，撷取杭州27家博物馆馆名、18处全国重点文物保护单位名称入印，以篆刻艺术雕琢杭州千年文脉，在方寸之间彰显城市文博底蕴。    (ECNS) -- Chinese researchers have developed a method that can directly and precisely detect trace rare-earth impurities in high-purity rare-earth materials, overcoming a long-standing challenge caused by matrix interference, CCTV News reported Monday.    The breakthrough, led by a key laboratory under the State Administration for Market Regulation at Jiangxi University of Science and Technology, uses inductively coupled plasma tandem mass spectrometry (ICP-MS/MS). The technique eliminates the need for matrix separation, offering higher sensitivity, accuracy and faster testing.    The team has also made advances in sample pretreatment and instrument calibration. The technologies are already widely used by rare-earth producers and testing institutions to improve quality control and testing efficiency.                        。
