Optically Enhanced Solid-State H-1 NMR Spectroscopy

David Lyndon Emsley, Jean-Philippe Ansermet, Federico De Biasi, Saumya Badoni, Dominik Józef Kubicki, Aaron James Rossini, Jonas Milani, Gabriele Stevanato, Michael Allan Hope, Moreno Lelli

Low sensitivity is the primary limitation to extendingnuclearmagnetic resonance (NMR) techniques to more advanced chemical andstructural studies. Photochemically induced dynamic nuclear polarization(photo-CIDNP) is an NMR hyperpolarization technique where ...

Enhanced Intersystem Crossing and Transient Electron Spin Polarization in a Photoexcited Pentacene–Trityl Radical

David Lyndon Emsley, Jacques-Edouard Moser, Aaron James Rossini, Dominik Józef Kubicki, Etienne Christophe Socie, Moreno Lelli, Gabriele Stevanato, Claudia Esther Avalos

Identifying and characterizing systems that generate well-defined states with large electron spin polarization is of high interest for applications in molecular spintronics, high-energy physics, and magnetic resonance spectroscopy. The generation of electr ...

One- and Two-Dimensional High-Resolution NMR from Flat Surfaces

David Lyndon Emsley, Aaron James Rossini, Brennan James Walder

Determining atomic-level characteristics of molecules on two-dimensional surfaces is one of the fundamental challenges in chemistry. High-resolution nuclear magnetic resonance (NMR) could deliver rich structural information, but its application to two-dime ...

Measurement of cos 2 beta in B-0 -> D((*))h(0) with D -> K-S(0)pi(+) pi(-) decays by a combined time-dependent Dalitz plot analysis of BABAR and Belle data

Olivier Schneider, Roberto Gargiani, Yiming Li, Mingkui Wang, Mithilesh Nayak, Chao Wang, Gaétan Charles Antoine Giriat, Tagir Aushev, Greig Alan Cowan, Sun Hee Kim

We report measurements of sin 2 beta and cos 2 beta using a time-dependent Dalitz plot analysis of B-0 -> D((*))h(0) with D -> K-S(0)pi(+)pi(-) decays, where the light unflavored and neutral hadron h(0) is a pi(0),eta, or omega meson. The analysis uses a c ...

The Dark Energy Survey: Data Release 1

Eduardo Sanchez, Xin Chen, Vanda Carla Costa Grisel, Aaron James Rossini, Yi Zhang, Jonathan Andrew Blazek, Jennifer Kaitlyn Olsen, Xi Chen, Augusto Martins Lima, Juan Andrei Villarroel Fernandez

We describe the first public data release of the Dark Energy Survey, DES DR1, consisting of reduced single-epoch images, co-added images, co-added source catalogs, and associated products and services assembled over the first 3 yr of DES science operations ...

First Evidence for cos 2 beta > 0 and Resolution of the Cabibbo-Kobayashi-Maskawa Quark-Mixing Unitarity Triangle Ambiguity

Olivier Schneider, Roberto Gargiani, Yiming Li, Mingkui Wang, Mithilesh Nayak, Gaétan Charles Antoine Giriat, Chao Wang, Tagir Aushev, Greig Alan Cowan, Sun Hee Kim

We present first evidence that the cosine of the CP-violating weak phase 2 beta is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent Dalitz plot analysis of B-0 -> ...

Structure of Lipid Nanoparticles Containing siRNA or mRNA by Dynamic Nuclear Polarization-Enhanced NMR Spectroscopy

David Lyndon Emsley, Aaron James Rossini, Arthur César Pinon, Jasmine Viger-Gravel

Here, we show how dynamic nuclear polarization (DNP) NMR spectroscopy experiments permit the atomic level structural characterization of loaded and empty lipid nanoparticles (LNPs). The LNPs used here were synthesized by the microfluidic mixing technique a ...

Dark Energy Survey Year 1 Results: A Precise H-0 Estimate from DES Y1, BAO, and D/H Data

Eduardo Sanchez, Aaron James Rossini, Jonathan Andrew Blazek, Augusto Martins Lima, Juan Andrei Villarroel Fernandez, Craig Matthew Smith

We combine Dark Energy Survey Year 1 clustering and weak lensing data with baryon acoustic oscillations and Big Bang nucleosynthesis experiments to constrain the Hubble constant. Assuming a flat Lambda CDM model with minimal neutrino mass (Sigma m(v), = 0. ...

BDPA-Nitroxide Biradicals Tailored for Efficient Dynamic Nuclear Polarization Enhanced Solid-State NMR at Magnetic Fields up to 21.1 T

David Lyndon Emsley, Aaron James Rossini, Dominik Józef Kubicki, Arthur César Pinon, Moreno Lelli, Georges Guévork Jean-Jacques Menzildjian, David Benjamin Roger Antoine Gajan

Dynamic nuclear polarization (DNP) solid-state nuclear magnetic resonance (NMR) has developed into an invaluable tool for the investigation of a wide range of materials. However, the sensitivity gain achieved with many polarizing agents suffers from an unf ...
