Nuclear quadrupole resonance spectroscopy with a femtotesla diamond magnetometer [PDF]

Science advances 9 (24), eadh3189 (2025), 2023
Sensitive Radio-Frequency (RF) magnetometers that can detect oscillating magnetic fields at the femtotesla level are needed for demanding applications such as Nuclear Quadrupole Resonance (NQR) spectroscopy. RF magnetometers based on Nitrogen-Vacancy (NV) centers in diamond have been predicted to offer femtotesla sensitivity, but published experiments ...

Sonochemically‐Induced Reduction of Alkenes to Alkanes with Ammonia

Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
Ammonia is used as a hydrogen source for the reduction of alkenes to alkanes. The originality stems from the use of cavitation bubbles that act as “microreactors” to break the N−H bond of NH3. As a result, this protocol does not involve any catalyst and it releases nitrogen (and partly hydrogen) as a sole co‐product.
