水碳酸镎络合物的稀释诱导的纳米二氧化镎（NPO 2）颗粒，其特征在于通过UV/维斯和X-射线吸收光谱和透射电子显微镜的内在形成。这一新的纳米晶NpO 2形成途径可能是放射性核素从废物处置库（即在近场碱性条件下）向地质环境（即在远场中性条件下）环境迁移的潜在情景。
The dilution of aqueous neptunium carbonate complexes induces the intrinsic formation of nanocrystalline neptunium dioxide (NpO2) particles, which are characterised by UV/Vis and X-ray absorption spectroscopies and transmission electron microscopy. This new route of nanocrystalline NpO2 formation could be a potential scenario for the environmental transport of radionuclides from the waste repository (i.e. under near-field alkaline conditions) to the geological environment (i.e. under far-field neutral conditions).
