In Project B10, Dynamic Nuclear Polarization (DNP) techniques are employed for Nuclear Magnetic Resonance (NMR) signal enhancement. DNP techniques enable overcoming the inherently low nuclear spin polarization and thus allow new applications of this important method. In this project, DNP hyperpolarization techniques are combined with NMR relaxometry as well as with high and medium field (benchtop) NMR. Both the electron-nuclear spin coupling itself and its application in process engineering are studied. The aim is to boost the sensitivity of NMR experiments manifold so that quantitative measurements of components at low concentrations or in small geometries such as microfluidic devices become possible.

在B10项目中，采用动态核极化（DNP）技术对核磁共振（NMR）信号进行增强。DNP技术能够克服固有的低核自旋极化，从而允许这一重要方法的新应用。在这个项目中，DNP超极化技术与核磁共振弛豫测量以及高场和中场（台式）核磁共振相结合。研究了电子-核自旋耦合本身及其在工艺工程中的应用。其目的是提高核磁共振实验的灵敏度，以便在低浓度或小几何形状（如微流体装置）下对成分进行定量测量成为可能。
