(Copernicus GmbH, 2019-02-14)The Nordic Centre of Excellence CRAICC (Cryosphere–Atmosphere Interactions in a Changing Arctic Climate), funded by NordForsk in the years 2011–2016, is the largest joint Nordic research and innovation initiative to date, aiming to strengthen research ... -
(MDPI AG, 2018-11-13)Metal oxide nanoparticles (NPs) are regarded as good candidates for many technological applications, where their functional environment is often an aqueous solution. The correct description of metal oxide electronic structure is still a challenge for ...

(Hindawi Limited, 2018-09-30)In this study, precipitation data for 483 synoptic stations, and the U&V component of wind and HGT data for 4 atmospheric levels were respectively obtained from IRIMO and NCEP/NCAR databases (1961–2013). The precipitation threshold of 1 mm and a minimum ...
-
(Wiley, 2020-01-21)Using density functional theory, we studied the bulk and surface properties of Li and Na electrodes on an atomistic level. To get a better understanding of the initial stages of surface growth phenomena (and thus dendrite formation), various self-diffusion ...
-
(Wiley, 2015-01-23)A novel heterogeneous dirhodium catalyst has been synthesized. This stable catalyst is constructed from dirhodium acetate dimer (Rh2(OAc)4) units, which are covalently linked to amine‐ and carboxyl‐bifunctionalized mesoporous silica (SBA‐15NH2COOH). ...

Nitroxide-labeled pyrimidines for non-covalent spin-labeling of abasic sites in DNA and RNA duplexes (Royal Society of Chemistry (RSC), 2014)Non-covalent and site-directed spin labeling gives easy access to spin-labeled nucleic acids for the study of their structure and dynamics by electron paramagnetic resonance (EPR) spectroscopy. In a search for improved spin labels for non-covalent ...
-
(Wiley, 2020-07)Two o‐benzoquinone derivatives of isoindoline were synthesized for use as building blocks to incorporate isoindoline nitroxides into different compounds and materials. These o‐quinones were condensed with a number of o‐phenylenediamines to form ...
-
(Royal Society of Chemistry (RSC), 2016)An isoindoline-nitroxide derivative of guanine (G, "G-spin") was shown to bind specifically and effectively to abasic sites in duplex RNAs. Distance measurements on a G-labeled duplex RNA with PELDOR (DEER) showed a strong orientation dependence. Thus, ...
-
(Royal Society of Chemistry (RSC), 2018)In the first example of site-directed spin-labeling of unmodified RNA, a pyrrolidine-nitroxide derivative of tetramethylrosamine (TMR) was shown to bind with high affinity to the malachite green (MG) aptamer, as determined by continuous-wave (CW) ...
-
(Wiley, 2020-01-21)Studying nucleic acids often requires labeling. Many labeling approaches require covalent bonds between the nucleic acid and the label, which complicates experimental procedures. Noncovalent labeling avoids the need for highly specific reagents and ...
-
(Springer Science and Business Media LLC, 2018-08-16)Bosonic condensation belongs to the most intriguing phenomena in physics, and was mostly reserved for experiments with ultra-cold quantum gases. More recently, it became accessible in exciton-based solid-state systems at elevated temperatures. Here, ...
-
(Royal Society of Chemistry (RSC), 2020)Copper(I) bis-phenanthroline complexes represent Earth-abundant alternatives to ruthenium-based sensitizers for solar energy conversion and photocatalysis. Improved understanding of the solvent- mediated excited-state structural dynamics can help ...
-
(Wiley, 2020-05-12)1,3‐Bis(diphenylene)‐2‐phenylallyl (BDPA)‐based radicals are of interest as polarizing agents for dynamic nuclear polarization (DNP). For this purpose, a BDPA‐nitroxide biradical, employing a phosphodiester linkage, was synthesized. Contrary to what ...
-
(Tethys, Journal of Weather and Climate of the Western Mediterranean, 2019)This paper focuses on the relationship between the 500 hPa height fluctuations and the associative atmosphere thickness (AT) over Iran and the Middle East between 1961 and 2013. For this purpose, atmospheric Geopotential Height (HGT) data of the 1000 ...

Optimal atomic structure of amorphous silicon obtained from density functional theory calculations (IOP Publishing, 2017-06-15)Atomic structure of amorphous silicon consistent with several reported experimental measurements has been obtained from annealing simulations using electron density functional theory calculations and a systematic removal of weakly bound atoms. The ...

(Elsevier BV, 2017-09)Background Since the introduction of pneumococcal conjugate vaccines, vaccine type pneumococcal carriage and disease has decreased world-wide. The aim was to monitor changes in the nasopharyngeal carriage of pneumococci, the distribution of serotypes ...
-
(Hindawi Limited, 2018)We study stability for dynamical systems specifed by autonomous stochastic diferential equations of the form dX(t) = f(X(t))dt + g(X(t))dW(t), with (X(t))t≥0 an Rd -valued Ito process and ˆ (W(t))t≥0 an RQ-valued Wiener process, and the functions f ...
-
(F1000Research, 2014-01-20)Promiscuity, the ability of an enzyme to catalyze diverse activities using the same active site, sets up the stage for the evolution of complex organisms through gene duplication and specialization. The detection of promiscuous motifs is crucial to ...
-
(American Chemical Society (ACS), 2017-07-21)Here we present a combined experimental and theoretical study on the fragmentation of o- and p-tetrafluorohydroquinone upon low energy electron attachment. Despite an identical ring-skeleton and identical functional groups in these constitutional ...
-
(Royal Society of Chemistry (RSC), 2015)Pulsed electron paramagnetic resonance (EPR) spectroscopy is a valuable technique for the precise determination of distances between paramagnetic spin labels that are covalently attached to macromolecules. Nitroxides have commonly been utilised as ...
