我们展示了如何通过动态核极化（DNP）增强锂皂石（R）的分散无机纳米颗粒的Si-29 NMR信号。直接DNP增强了未成对电子附近Si-29核的信号，而通过H-1的间接DNP增强了更远位置的信号。
We show how the Si-29 NMR signals of dispersed inorganic nanoparticles of laponites(R) can be enhanced by Dynamic Nuclear Polarization (DNP). The direct DNP enhances the signals of Si-29 nuclei near unpaired electrons, whereas the indirect DNP via H-1 enhances the signals of more remote sites.
