 In February 2003, she received the L'Oréal-UNESCO Awards for Women in Science Award . Li died on January 24, 2020 in Beijing . Personal life Li was married to fellow physicist Fan Haifu In the 1970s, Li Fanghua and Fan Haifu cooperated to explore the combination of diffraction methods and high-resolution electron microscopy, and created a new image processing theory and technology in high-resolution electron microscopy. Later, she and her students established an unwinding processing technology based on the principle of maximum entropy. It provides an important way to determine the tiny crystal structure. It has been successfully applied to determine the crystal structure of materials such as high-temperature superconductors. .
