Whether in the backbone of oligonucleotides, in metabolites such as ATP or phospholipids, life as we know it would be inconceivable without phosphorus. Because of this prominent role, phosphorus must have played an essential role also 4 billion years ago in the emergence of life. Phosphorus, although geologically widespread, is poorly soluble and therefore not available for prebiotic chemistry. In this project, we will investigate phosphorus leaching of common minerals such as Apatite or phosphorous-rich glasses over a wide parameter range of temperature, pH and pressure and explore the heat flux-driven separation of phosphate as well as phosphorylation in multiphase thermal non-equilibrium systems.

无论是在寡核苷酸的骨架中，还是在ATP或磷脂等代谢物中，我们所知道的生命如果没有磷是不可想象的。由于这种突出的作用，磷一定在40亿年前的生命出现中也发挥了重要作用。磷虽然在地质上广泛分布，但溶解性很差，因此无法用于益生元化学。在这个项目中，我们将研究在温度，pH值和压力的宽参数范围内常见矿物如磷灰石或富磷玻璃的磷浸出，并探索热通量驱动的磷酸盐分离以及多相热非平衡系统中的磷酸化。
