Article Synopsis
- Metal stable isotopes are gaining popularity in fields such as planetary science and medical research, which necessitates efficient analysis methods for small and valuable samples.
- The study presents a new, highly efficient method called microultrasonic single-droplet nebulization (MUSDN) that significantly improves sensitivity for analyzing lithium (Li) and copper (Cu) isotopes compared to traditional techniques.
- MUSDN requires considerably less sample (1-2 ng) and is faster than conventional methods, showing excellent precision and accuracy validated against various standards and real serum samples, making it beneficial for isotope research with limited samples.
The teaching of Chinese as a second language has become increasingly crucial for promoting cross-cultural exchange and mutual learning worldwide. However, traditional approaches to international Chinese language teaching have limitations that hinder their effectiveness, such as outdated teaching materials, lack of qualified instructors, and limited access to learning facilities. To overcome these challenges, it is imperative to develop intelligent and visually engaging methods for teaching international Chinese language learners.

Steady meteorological conditions are important external factors affecting air pollution. In order to analyze how adverse meteorological variables affect air pollution, surface synoptic situation patterns and meteorological conditions during heavy pollution episodes are discussed. The results showed that there were 78 RPHPDs (regional PM pollution days) in Jiangsu, with a decreasing trend year by year.
