    Rafeindasegullitrófsgreiningu (e. Electron Paramagnetic Resonance, EPR) er reglubundið beitt í rannsóknum á byggingu og hreyfingu kjarnsýra til að fá upplýsingar um starfsemi þeirra og hlutverk. Innleiðing meðseglandi kjarna á ákveðinn stað í kjarnsýrum ...
  • HASSOUN, ABDO; Gudjónsdóttir, María; Prieto, Miguel A.; Garcia-Oliveira, Paula; Simal-Gandara, Jesus; Marini, Federico; Di Donato, Francesca; D'Archivio, Angelo; Biancolillo, Alessandra (MDPI AG, 2020-08-14)
    In this review, we summarize the most recent advances in monitoring changes induced in fish and other seafood, and meat and meat products, following the application of traditional processing processes by means of conventional and emerging advanced ...
  • Lv, Zhiyong; Zhang, Penglin; Benediktsson, Jon Atli (MDPI AG, 2017-03-17)
    Aerial image classification has become popular and has attracted extensive research efforts in recent decades. The main challenge lies in its very high spatial resolution but relatively insufficient spectral information. To this end, spatial-spectral ...

    Dynamic nuclear polarization (DNP) is an efficient method to overcome the inherent low sensitivity of magic-angle spinning (MAS) solid-state NMR. We report a new polarizing agent (bcTol), designed for biological applications, that yielded an enhancement ...
  • Rees, Julian A.; Bjornsson, Ragnar; Kowalska, Joanna K.; Lima, Frederico A.; Schlesier, Julia; Sippel, Daniel; Weyhermüller, Thomas; Einsle, Oliver; Kovacs, Julie A.; DeBeer, Serena (Royal Society of Chemistry (RSC), 2017)
    An investigation of the active site cofactors of the molybdenum and vanadium nitrogenases (FeMoco and FeVco) was performed using high-resolution X-ray spectroscopy. Synthetic heterometallic iron–sulfur cluster models and density functional theory ...
  • Belyakov, Alexander V.; Sigolaev, Yrii F.; Shlykov, Sergey A.; Wallevik, Sunna Ó.; Jónsdóttir, Nanna R.; Jónsdóttir, Sigríður; Kvaran, Agust; Bjornsson, Ragnar; Árnason, Ingvar (Elsevier BV, 2017-03)
    The conformational preference of the cyano group of the 1-cyano-1-silacyclohexane was studied experimentally by means of gas electron diffraction (GED) and dynamic nuclear magnetic resonance (DNMR) as well as by quantum chemical (QC) calculations ...

(Royal Society of Chemistry (RSC), 2019-04-22)
    Light-driven molecular reactions are dictated by the excited state potential energy landscape, depending critically on the location of conical intersections and intersystem crossing points between potential surfaces where non-adiabatic effects govern ...
  • Grytz, C. M.; Marko, A.; Cekan, P.; Sigurdsson, Snorri; Prisner, Thomas F. (Royal Society of Chemistry (RSC), 2016)
    The cocaine aptamer is a DNA three-way junction that binds cocaine at its helical junction. We studied the global conformation and overall flexibility of the aptamer in the absence and presence of cocaine by pulsed electron-electron double resonance ...

    Hyperspectral remote sensing is based on measuring the scattered and reflected electromagnetic signals from the Earth’s surface emitted by the Sun. The received radiance at the sensor is usually degraded by atmospheric effects and instrumental (sensor) ...
  • Saha, Subham; Jagtap, Anil P.; Sigurdsson, Snorri (Royal Society of Chemistry (RSC), 2015)
    Two aromatic isothiocyanates, derived from isoindoline nitroxides, were synthesized and selectively reacted with 2′-amino groups in RNA. The spin labels displayed limited mobility in RNA, making them promising candidates for distance measurements by ...
