However, the efficient production of D or H deuteride in a controlled manner is challenging, and rational H isotope enrichment protocols are still lacking. Here, we demonstrate a highly efficient exchange reaction from H to D on the surface of nanocrystalline Si (n-Si). Fourfold enrichment of D termination was successfully achieved by dipping n-Si into a dilute D solution. By determining the surface-localized vibrational modes for H- and D-terminated n-Si using inelastic neutron scattering spectroscopy, we found that the physical mechanism responsible for this enrichment originates from the difference in the zero-point oscillation energies and entropies of the surface-localized vibrations. Theoretically, the extent of enrichment could be greatly enhanced (similar to 15 times) using a gas-phase reaction. This enrichment protocol, which avoids the use of precious metal catalysts, opens the way for sustainable H-to-heavy H exchange reactions.}, year = {2021}, eissn = {2475-9953}, orcid-numbers = {Kanemitsu, Yoshihiko/0000-0002-0788-131X} } @mastersthesis{MTMT:32513627, title = {Failure mechanisms implementation into SiGe HBT compact model operating close to safe operating area edges}, url = {https://m2.mtmt.hu/api/publication/32513627}, author = {Couret, Marine}, publisher = {University of Bordeaux}, unique-id = {32513627}, year = {2020} } @article{MTMT:31920376, title = {Effects of water transport on deuterium isotope separation during polymer electrolyte membrane water electrolysis}, url = {https://m2.mtmt.hu/api/publication/31920376}, author = {Harada, K. and Tanii, R. and Matsushima, H. and Ueda, M. and Sato, K. and Haneda, T.}, doi = {10.1016/j.ijhydene.2020.08.256}, journal-iso = {INT J HYDROGEN ENERG}, journal = {INTERNATIONAL JOURNAL OF HYDROGEN ENERGY}, volume = {45}, unique-id = {31920376}, issn = {0360-3199}, year = {2020}, eissn = {1879-3487}, pages = {31389-31395} } @article{MTMT:32513625, title = {1320 nm Light Source from Deuterium Treated Silicon}, url = {https://m2.mtmt.hu/api/publication/32513625}, author = {Kalem, S.}, doi = {10.1109/OJNANO.2020.3025167}, journal-iso = {IEEE OPEN J NANOTECH}, journal = {IEEE OPEN JOURNAL OF NANOTECHNOLOGY}, volume = {1}, unique-id = {32513625}, year = {2020}, eissn = {2644-1292}, pages = {88-94} } @article{MTMT:31014718, title = {Communication-Deuterium Isotope Separation by Solid Polymer Electrolyte Water Electrolysis}, url = {https://m2.mtmt.hu/api/publication/31014718}, author = {Matsushima, Hisayoshi and Sato, Hanako and Ueda, Mikito and Ito, Hiroshi}, doi = {10.1149/2.0071910jes}, journal-iso = {J ELECTROCHEM SOC}, journal = {JOURNAL OF THE ELECTROCHEMICAL SOCIETY}, volume = {166}, unique-id = {31014718}, issn = {0013-4651}, abstract = {Electrolytic deuterium (D) separation from protium-containing solution has been investigated. Proton (PEM) and anion exchange membrane (AEM) electrolysis were performed at constant current. The mass analysis of hydrogen gas and water vapor was carried out. For both PEM and AEM electrolysis, the D concentration in the evolved hydrogen gas was lower than that of the initial electrolytic solution. The D concentration in the water vapor was unchanged by PEM electrolysis, but was increased by AEM. The separation factor of PEM was smaller than that of AEM, which was attributed to the humidification state on platinum catalyst.
