The acquired knowledge about bio-silica issued from diatomite/diatom is growing step by step after the increasing interest on bio-sourced material. This work conducts a deep analysis on morphological and chemical properties of bio-silica issued from fossil origin (diatomaceous earth) and living one (algal paste) and investigates whether substituting synthetic silica by bio-silica is largely benefit regarding better architectural morphology of frustules and lower ecological footprint.

【万家寨引黄工程今年将向永定河生态补水2.55亿立方米】
Wanjiazhai, a major water control project on the Yellow River, will replenish 255 million cubic meters of water this year to the Yongding River to support ecological restoration in the Beijing-Tianjin-Hebei area. The Yongding river basin is one of the most important water conservation areas, an ecological barrier, and a natural corridor in the Chinese capital and its surrounding areas.

为进一步提升永定河生态功能，万家寨引黄工程今年将向永定河调引黄河水2.55亿立方米，助力复苏永定河生态环境。永定河是海河流域重要水系之一，是京津冀晋地区的重要水源涵养区、生态屏障和生态廊道。2023年，在流域有关方面共同努力下，永定河自1996年断流以来，首次实现全年全线有水，水量调度工作取得突破性进展。
