Wstęp do tribologii i tribochemia
(Wydawnictwo Uniwersytetu Łódzkiego, 2005)Materiał niniejszej książki może być wprowadzeniem ułatwiającym zrozumienie tribochemii procesu tarcia. Część pierwsza – Wstęp do tribologii zawiera podstawową wiedzę o tarciu, zużyciu i adhezji powierzchni ciała stałego, ... -
1JCH couplings in Group14/IVA tetramethyls from the gas-phase NMR and DFT structural study: a search for the best computational protocol
(The Royal Society of Chemistry, 2014-05-15)Four tetramethyl compounds EMe4 (E = C, Si, Ge, and Pb) were studied by high-resolution NMR spectroscopy in gaseous and liquid states at 300 K. Extrapolation of experimental vapor-phase C-H J-couplings to a zero-pressure ... -
Conductometric Studies of 1-Ethyl-3-methylimidazolium Tetrafluoroborate and 1-Butyl-3-methylimidazolium Tetrafluoroborate in 1-Propanol at Temperatures from (283.15 to 318.15) K
(Electrochemical Science Group, 2014-03)The electrical conductances of dilute solutions of the ionic liquids 1-ethyl-3-methylimidazolium tetrafluoroborate [emim][BF4] and 1-butyl-3-methylimidazolium tetrafluoroborate [bmim][BF4] in 1-propanol have been measured ... -
Carbon-13 longitudinal relaxation time measurements and DFT-GIAO NMR computations for two ammonium ions of a tetraazamacrocyclic scorpiand system
(Springer Netherlands, 2013)Spin-lattice relaxation times, T1s, for 13C nuclei in two cations Hn1n+ (n = 1, 5)of N-(2-amino-ethyl)-cyclam (1, scorpiand) were determined by means of 13C{1H} NMR experiments in aqueous solution at pH 11.5 and 0.2. ... -
Doubly-bridged PNP-lariat ethers and their complexes with silver(I) ions in methanol solution
(The Royal Society of Chemistry, 2013-10-21)We report the preparation of four new double-bridged PNP-lariat etherderivatives L1 – L4 synthesized from precursor 1 by the subsequent substitution of chlorine atoms. The process consists of two steps. In ... -
Matrix isolation and spectroscopic properties of the methylsulfinyl radical CH3(O)S˙
(The Royal Society of Chemistry, 2013-08-15)The atmospherically highly relevant methylsulfinyl radical CH3(O)S˙ was generated thermally under flash pyrolysis conditions and isolated in Ar matrices at 10 K; the allyl radical is a byproduct. CH3(O)S˙ and its D3- and ...
