Improved Phase-Modulated Homonuclear Dipolar Decoupling for Solid-State NMR Spectroscopy from Symmetry Considerations

We explore the effects of symmetry on the performance of phase-modulated homonuclear dipolar decoupling in H-1 solid-state NMR. We demonstrate that the symmetry of the DUMBO family of decoupling sequences is the result of two well-defined symmetry expansio ...

Evolution of magnetic and crystal structures in the multiferroic FeTe2O5Br

Helmuth Berger

Neutron diffraction and nuclear quadrupole resonance (NQR) measurements were employed to investigate magnetic order in the nonferroelectric phase preceding the low-temperature multiferroic state in FeTe2O5Br. Refinement of the neutron diffraction data and ...

Full-duplex Communication and Remote Powering Implementation of an Electronic Knee Implant

Catherine Dehollain, Oguz Atasoy

Full-duplex communication is realized by using ASK modulation for downlink (the channel from controller to the implant) and by using FSK modulation for uplink (from implant to the controller). The ASK modulation is done at the remote powering frequency and ...

Adsorbed and near surface structure of ionic liquids at a solid interface

Kislon Voitchovsky, Juan José Segura Sugranes

The structure of solid-ionic liquid (IL) interfaces has been characterised with unprecedented clarity by employing a range of atomic force microscopy (AFM) imaging techniques and tip pressures appropriate for the system under study. Soft contact and amplit ...

Fine DNA structure revealed by constant height frequency modulation AFM imaging

Giovanni Dietler, Dusan Vobornik, Andrea Cerreta

Few examples of sub nanometer resolution on biomolecules can be found in literature. In particular, AFM experiments on DNA mostly fail to show the double helical groove periodicity, and so far such a feat was only achieved in liquid. Here we describe a met ...

Modulations of Spin Echoes in Liquids

Geoffrey Bodenhausen

Echo modulations that arise in Carr–Purcell–Meiboom–Gill (CPMG) spin echo sequences and stem from homonuclear couplings can be suppressed by different methods. The evolution under homonuclear couplings can be either ‘‘locked’’ or ‘‘refocused’’, leading to ...

Broadband on-chip optical non-reciprocity using phase modulators

Christophe Marcel Georges Galland, Ran Ding

Breaking the reciprocity of light propagation in a nanoscale photonic integrated circuit (PIC) is a topic of intense research, fostered by the promises of this technology in areas ranging from experimental research in classical and quantum optics to high-r ...

Wireless Data and Power Transmission Aiming Intracranial Epilepsy Monitoring

Catherine Dehollain, Gürkan Yilmaz, Oguz Atasoy

This study presents a wireless power and data transmission system to overcome the problems in intracranial epilepsy monitoring associated with transcutaneous wires. Firstly, a wireless power transfer link based on inductive coupling is implemented and a po ...

Automated transfer and injection of hyperpolarized molecules with polarization measurement prior to in vivo NMR

Mor-Miri Mishkovsky, Tian Cheng, Arnaud Comment, Josefina Adriana Maria Bastiaansen

Hyperpolarized magnetic resonance via dissolution dynamic nuclear polarization necessitates the transfer of the hyperpolarized molecules from the polarizer to the imager prior to in vivo measurements. This process leads to unavoidable losses in nuclear pol ...
