Efficient DNP at high fields and fast MAS with antenna-sensitized dinitroxides

David Lyndon Emsley, Amrit Venkatesh

Dynamic Nuclear Polarization (DNP) can significantly enhance the sensitivity of solid-state NMR. In DNP, microwave irradiation induces polarization transfer from unpaired electron spins to 1H nuclear spins via hyperfine couplings and spin-diffusion. The st ...

Broad-wave-vector spin pumping of flat-band magnons

Jean-Philippe Ansermet

We report the experimental observation of large spin -pumping signals in the YIG/Pt system driven by broad -wave -vector spin -wave spin current. 280-nm-wide microwave inductive antennas offer broad -wavevector excitation, which, in combination with the qu ...

Stabilization of Inorganic Perovskite Solar Cells with a 2D Dion-Jacobson Passivating Layer

Guixiang Li

Inorganic metal halide perovskites such as CsPbI3 are promising for high-performance, reproducible, and robust solar cells. However, inorganic perovskites are sensitive to humidity, which causes the transformation from the black phase to the yellow & delta ...

Lock-in Raman difference spectroscopy

Christophe Moser, Damien Claude-Marie Loterie, Chiara Bonati, Rémy Jean Daniel Dornier, Victoria Alexandrine Julia Suzanne Marthe Fay

Shifted Excitation Raman Difference Spectroscopy (SERDS) is a non-destructive chemical analysis method capable of removing the fluorescence background and other disturbances from the Raman spectrum, thanks to the independence of the fluorescence with respe ...

Optimized Detection of Hypoglycemic Glucose Ranges in Human Serum by Raman Spectroscopy with 532 nm Laser Excitation

Christian Enz, Sandro Carrara, Assim Boukhayma, Ata Jedari Golparvar

Raman scattering-based biomedical detection has usually been proposed with near-infrared laser sources. However, a low-cost CMOS imager's quantum efficiency is optimum around green wavelength, and their sensitivity substantially decreases in near-infrared ...

Deciphering Iron-Dependent Activity in Oxygen Evolution Catalyzed by Nickel-Iron Layered Double Hydroxide

Xile Hu, Lichen Bai, Seunghwa Lee

Nickel iron oxyhydroxide is the benchmark catalyst for the oxygen evolution reaction (OER) in alkaline medium. Whereas the presence of Fe ions is essential to the high activity, the functions of Fe are currently under debate. Using oxygen isotope labeling ...

Unveiling Temperature-Dependent Scattering Mechanisms in Semiconductor Nanowires Using Optical-Pump Terahertz-Probe Spectroscopy

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Heidi Andrea Potts, Francesca Amaduzzi

Optical-pump terahertz-prohe (OPTP) spectroscopy is a powerful, non-contact tool for extracting the electrical conductivity within a material. In this work, we show how OPTP spectroscopy can he used to extract the temperature-dependent electron mobility an ...
