DOI: 10.1016/j.ssnmr.2019.04.008

Abstract: Dynamic nuclear polarization (DNP) enhanced nuclear magnetic resonance (NMR) offers a promising route to studying local atomic environments at the surface of both crystalline and amorphous materials. We take advantage of unpaired electrons due to… read more here.

DOI: 10.1021/acs.jpcc.6b11065

Abstract: We use dynamic nuclear polarization (DNP)-enhanced nuclear magnetic resonance (NMR) at liquid helium temperatures to directly detect hydrogen attached to the surface of silicon microparticles. The proton NMR spectrum from a dry sample of polycrystalline… read more here.

DOI: 10.1364/ol.383139

Abstract: We study the behavior of silicon microparticles in a 1064 nm Gaussian-beam optical tweezers, showing that this semiconductor can be used to perform different types of optical manipulation experiments. Depending on the focal position and… read more here.
