Phosphoryl Radicals from Trivalent Iminyl Phosphines: A Photocatalytic Approach to N‐Phosphoryl Azetidines

open access: yesAngewandte Chemie, EarlyView.
Photochemically generated phosphoryl radicals from iminyl phosphines enable strain‐release addition to azabicyclobutanes, providing access to elusive N‐phosphoryl azetidines. Combined experimental, computational, and EPR studies reveal an unconventional water‐assisted photoredox pathway.

Internal polarized gas targets: systematic studies on intensity and correlated effects

open access: yes, 2009
The work carried out during the PhD was dedicated to the study of high-density polarized gas targets used in high-energy physics. The thesis is related to the PAX experiment, which aims to produce a beam of polarized anti-protons, by means of spin ...

Elucidation of Lignin and Polysaccharide Linkages in Wheat Straw by 2H/13C Isotopic Tracer

open access: yesBioResources, 2022
To elucidate chemical linkages between lignin and polysaccharides, the aqueous mixed solutions of coniferin-[α-13C], syringin-[α-13C], D-glucose-[6-2H], and phenylalanine ammonia-lyase inhibitor were injected into a living wheat stalk.

Plasma pulse induced dust release from tungsten co-deposited layer

open access: yesNuclear Fusion
Tungsten co-deposited layers in fusion devices are a significant potential source of plasma-contaminating dust. This study investigates the mechanisms of dust release from helium–tungsten (He–W) and deuterium–tungsten (D–W) layers under high-density ...

Recovery of deuterium from H-D gas mixture in thermal diffusion columns connected in series with countercurrent-flow transverse sampling streams

open access: yes, 2016
The equations for predicting the degrees of separation of H2, HD and D2 from H–D gas mixture by thermal diffusion in countercurrent-flow concentric-tube Frazier schemes of single and multiple columns, have been derived.

Electric field induced spectra of molecular hydrogen, deuterium and deuterium hydride [PDF]

open access: yes, 1968
The electric field induced spectra of molecular hydrogen, deuterium and deuterium hydride was observed in the pressure range of 0 to 600 psi. Thirteen lines each of the fundamental vibration-rotation band were observed for hydrogen and deuterium and nine

Hydrogen-Deuterium-Exchange-Based Mass Distribution Shifts in High-Resolution Cyclic Ion Mobility Separations

open access: yes
The mass distribution of ions influences separations in ion mobility spectrometry-mass spectrometry (IMS-MS). Herein, we introduce a method to induce mass distribution shifts for various analytes using hydrogen-deuterium exchange (HDX) immediately prior ...
