Enhanced phosphate cycling in 3 phase-systems – Heat fluxes trigger the liberation and back-precipitation of phosphate, boosting prebiotic chemistry (P03)

无论是在寡核苷酸的骨架中，还是在ATP或磷脂等代谢物中，没有磷，我们所知的生命都是不可想象的。由于这种突出的作用，磷一定也在40亿年前生命的出现中发挥了至关重要的作用。虽然磷在地质上广泛存在，但它的溶解性很差，因此不能用于益生化学。在本项目中，我们将研究磷灰石或富磷玻璃等常见矿物在较宽的温度、pH和压力参数范围内的磷浸出，并探索多相热非平衡体系中热流驱动的磷酸盐分离和磷酸化。

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.
