Autor: Václav Římal, Eleonora I. Bunyatova, Helena Štěpánková
Publikováno v: Molecules, Vol 29, Iss 3, p 738 (2024)
Dynamic nuclear polarization for nuclear magnetic resonance (NMR) spectroscopy and imaging uses free radicals to strongly enhance the NMR signal of a compound under investigation. At the same time, the radicals shorten significantly its nuclear spin

Autor: Václav Římal, Ondřej Socha, Josef Štěpánek, Helena Štěpánková
Publikováno v: Journal of Spectroscopy, Vol 2015 (2015)
Effect of cytosine methylation on DNA duplexes was studied by using a model system of three self-complementary DNA octamers containing central CpG motif surrounded by a couple of AT base pairs, CAACGTTG, CATCGATG, and CTTCGAAG, and their analogues wi

With the advent of faster magic-angle spinning (MAS) and higher magnetic fields, the resolution of biomolecular solid-state nuclear magnetic resonance (NMR) spectra has been continuously increasing. As a direct consequence, the always narrower spectr

Issue 10
Minerals, Vol 10, Iss 852, p 852 (2020)
In the last 20 years, laboratory work on geopolymer technology has been confronted with the necessity to determine whether a certain clay material has the properties necessary to form genuine geopolymer when thermally treated and alkalized. The asses

Conformations, equilibrium thermodynamics and rotational barriers of secondary thiobenzanilides
Autor: Václav Profant, Ján Kozic, Jarmila Vinšová, Jiří Kuneš, Václav Římal, Zdeněk Novák
Publikováno v: Tetrahedron. 72:2072-2083
The article deals with conformational behaviour of 2-methoxy-2′-hydroxythiobenzanilides. The CS-NH group of these compounds preferentially adopts the Z-conformation. Entropy favours the Z-conformer over the E-conformer, whereas enthalpy slightly fa

Autor: Václav Římal, Kateřina Mudroňová, Peter Mojzeš
Publikováno v: Vibrational Spectroscopy. 82:60-65
Raman spectroscopy was used to directly compare different abilities of monomeric ribo - and 2′ - deoxyribo guanosine 5′-monophosphates to constitute G-quartets and their supramolecular self-assemblies stabilized by Na + and K + cations in pH-neut
