Dynamics of frequency-swept nuclear spin optical pumping in powdered diamond at low magnetic fields
(National Academy of Sciences, 2019-02)
A broad effort is underway to improve the sensitivity of NMR through the use of dynamic nuclear polarization. Nitrogen vacancy (NV) centers in diamond offer an appealing platform because these paramagnetic defects can be ...
Silver deposition optimization process on ultrananocrystalline diamond applied to nitrate reduction
(Taylor & Francis Ltd, 2019-07-17)
Nitrate is a serious contaminant of ground and surface water, which cause high concern in the field of health and environmental protection. In this work, a ternary composite of silver/boron-doped ultrananocrystalline ...

(MDPI, 2018-04)
The fabrication of engineered lattice structures has recently gained momentum due to thedevelopment of novel additive manufacturing techniques. Interest in lattice structures resides not only in the possibility of obtaining ...
Development of a novel polycrystalline diamond composite using tantalum as a binder
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2021-06-28)
Polycrystalline diamond (PCD) is widely applied in the cutting and drilling industries due
to its excellent mechanical properties. Currently, several researchers have been studying
the use of different binders in its ...
Two-Electron-Spin Ratchets as a Platform for Microwave-Free Dynamic Nuclear Polarization of Arbitrary Material Targets
(American Chemical Society, 2019-04-18)
Optically pumped color centers in semiconductor powders can potentially induce high levels of nuclear spin polarization in surrounding solids or fluids at or near ambient conditions, but complications stemming from the ...
Influence of substrate surface topography in the deposition of nanostructured diamond-like carbon films by high density plasma chemical vapor deposition
(ELSEVIER SCIENCE SA, 2009)
In this work, we have studied the influence of the substrate surface condition on the roughness and the structure of the nanostructured DLC films deposited by High Density Plasma Chemical Vapor Deposition. Four methods ...
