Alexander Benjamin Barnes is an American chemist. Educated at Whitman College and the Massachusetts Institute of Technology, he has taught at Washington University in St. Louis and ETH Zurich.

Career

Alexander Barnes earned his undergraduate degree in chemistry in 2003 from Whitman College in Walla Walla, Washington. After earning his Ph.D. in chemistry in 2011 from the Massachusetts Institute of Technology under advisor Robert G. Griffin, he worked as a postdoctoral research associate at Stanford University. [1] He was an assistant chemistry professor of chemistry at Washington University in St. Louis from 2012 to 2019, [2] and is presently a Full Professor of Solid State NMR Spectroscopy at the Swiss Federal Institute of Technology ETH Zurich. [3]

Barnes specializes in developing hardware for the interrogation of chemical structures using Magnetic Resonance Spectroscopy. Some of his most notable innovations include the use of spherical sample containers instead of cylindrical ones [4] and frequency-agile gyrotrons for use in dynamic nuclear polarization (DNP) NMR experiments. [5]

In 2018, Barnes received the Camille Dreyfus Teacher-Scholar Award. [6] [7]

At the 2019 Experimental Nuclear Magnetic Resonance Conference [8] in Asilomar, California, California, Barnes received the Varian Young Investigator award. [9] [10]

Solid-state NMR (ssNMR) spectroscopy is a technique for characterizing atomic level structure in solid materials e.g. powders, single crystals and amorphous samples and tissues using nuclear magnetic resonance (NMR) spectroscopy. The anisotropic part of many spin interactions are present in solid-state NMR, unlike in solution-state NMR where rapid tumbling motion averages out many of the spin interactions. As a result, solid-state NMR spectra are characterised by larger linewidths than in solution state NMR, which can be utilized to give quantitative information on the molecular structure, conformation and dynamics of the material. Solid-state NMR is often combined with magic angle spinning to remove anisotropic interactions and improve the resolution as well as the sensitivity of the technique.

Herbert Sander Gutowsky was an American chemist who was a professor of chemistry at the University of Illinois Urbana-Champaign. Gutowsky was the first to apply nuclear magnetic resonance (NMR) methods to the field of chemistry. He used nuclear magnetic resonance spectroscopy to determine the structure of molecules. His pioneering work developed experimental control of NMR as a scientific instrument, connected experimental observations with theoretical models, and made NMR one of the most effective analytical tools for analysis of molecular structure and dynamics in liquids, solids, and gases, used in chemical and medical research, His work was relevant to the solving of problems in chemistry, biochemistry, and materials science, and has influenced many of the subfields of more recent NMR spectroscopy.

Rafael Brüschweiler is a scientist who studies nuclear magnetic resonance (NMR). He is credited for the development of Covariance NMR, which shortens the NMR measurement time for multidimensional spectra of both solution and solid-state NMR. It also allows for easier analysis and interpretation. For this achievement he was awarded the Laukien Prize in NMR Spectroscopy at the 47th Experimental Nuclear Magnetic Resonance Conference (ENC). He is also a leading scientist in NMR-based metabolomics and protein NMR.

<span class="mw-page-title-main">Nuclear magnetic resonance</span> Spectroscopic technique based on change of nuclear spin state

Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus. This process occurs near resonance, when the oscillation frequency matches the intrinsic frequency of the nuclei, which depends on the strength of the static magnetic field, the chemical environment, and the magnetic properties of the isotope involved; in practical applications with static magnetic fields up to ca. 20 tesla, the frequency is similar to VHF and UHF television broadcasts (60–1000 MHz). NMR results from specific magnetic properties of certain atomic nuclei. Nuclear magnetic resonance spectroscopy is widely used to determine the structure of organic molecules in solution and study molecular physics and crystals as well as non-crystalline materials. NMR is also routinely used in advanced medical imaging techniques, such as in magnetic resonance imaging (MRI).

The Russell Varian Prize was an international scientific prize awarded for a single, high-impact and innovative contribution in the field of nuclear magnetic resonance (NMR), that laid the foundation for the development of new technologies in the field. It honored the memory of Russell Varian, the pioneer behind the creation of the first commercial NMR spectrometer and the co-founder, in 1948, of Varian Associates, one of the first high-tech companies in Silicon Valley. The prize carried a monetary award of €15,000 and it was awarded annually between the years 2002 and 2015 by a committee of experts in the field. The award ceremony alternated between the European Magnetic Resonance (EUROMAR) Conference and the International Council on Magnetic Resonance in Biological Systems (ICMRBS) Conference. Originally, the prize was sponsored by Varian, Inc. and later by Agilent Technologies, after the latter acquired Varian, Inc. in 2010. The prize was discontinued in 2016 after Agilent Technologies closed its NMR division.
