Using recent theory, we show that the field dependence of the DQC signal is sensitive to the relative orientation of the two g-tensor axes. The data is also in great agreement with theoretical predictions. (2/2) #ESR.

Check out our newest work on Q‑band DQC! . Q-band DQC offers distinct advantages for dual nitroxide-labeled proteins, including deep dipolar modulations, minimal background decay at micromolar concentrations, and increased sensitivity with the incorporation of deuterium. (1/2).

Josh and Shramana’s paper on a new rigid Cu(II)based DNA label is now published in JACS! The new Cu(II) label is anchored inside the DNA helix and is sensitive to dynamic and structural fluctuations of the duplex induced by protein binding.

circularly polarized light using MCD. This work points to advances in improving optically induced magnetization-initializable qubits. Great work to all, and congrats on the first Pitt paper, Dr. Transue! (2/2)

We recently collaborated with the Transue Group at @Pitt_Chemistry and published a communication in @J_A_C_S! We used pulsed EPR to show the long relaxation times of a series of tungsten(V) chalcogenide complexes. These molecules have large spin-sensitive responses to (1/2).

Josh and Shramana's review has been accepted for publication in the 80th EPR anniversary edition of Applied Magnetic Resonance. It is cleverly titled "PELDOR to the metal: Cu(II)-based labels put a new spin on distance measurements". Congratulations!.

Congratulations to Josh Casto for passing his PhD defense last week on April 16! . 16th PhD graduate on the 16th!

Sunil has been selected as a recipient of the 2024 Provost's Award for Excellence in Doctoral Mentoring at the University of Pittsburgh. Congratulations and well deserved! @Pitt_Chemistry.

We were also able to measure 25 nM protein concentration in 40 hours, which is the current concentration limit we have seen with EPR distance measurements!.

Alysia and Zikri’s paper on Q-band nitroxide double quantum coherence measurements is now published online in J. Phys. Chem. Lett.! . In this work, we were able to achieve 100% modulation depths and 50 nM distance measurements in 12 hours.
