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. ...
Dialkyldithiophosphate Acids (HDDPs) as Effective Lubricants of Sol–Gel Titania Coatings in Technical Dry Friction Conditions
Piwoński, Ireneusz 
; Kisielewska, Aneta (Springer, 2012)
; Kisielewska, Aneta (Springer, 2012)
The goal of this study was the investigation of
the effectiveness of dialkyldithiophosphate acids (HDDPs)
films in improving the tribological properties of thin, sol–
gel derived titania coatings. Amorphous, anatase, ...
Treatment of chronic hemodialysis patients with low-dose fenofibrate effectively reduces plasma lipids and affects plasma redox status
Makówka, Agnieszka ; ; Chwatko, Grażyna ; ; (BioMed Central, 2012)
; ; Chwatko, Grażyna ; ; (BioMed Central, 2012)
Dyslipidemia is common in chronic hemodialysis patients and its underlying mechanism is complex. Hemodialysis causes
an imbalance between antioxidants and production of reactive oxygen species, which induces the oxidative ...
The Effects of Cocaine on Different Redox Forms of Cysteine and Homocysteine, and on Labile, Reduced Sulfur in the Rat Plasma Following Active versus Passive Drug Injections
; Chwatko, Grażyna ; ; ; ; ; (Springer Verlag, 2013)
; ; ; ; ; (Springer Verlag, 2013)
The aim of the present studies was to evaluate
cocaine-induced changes in the concentrations of different
redox forms of cysteine (Cys) and homocysteine (Hcy),
and products of anaerobic Cys metabolism, i.e., labile,
reduced ...
Application of a Graphene Oxide–Carbon Paste Electrode for the Determination of Lead in Rainbow Trout from Central Europe
SMARZEWSKA, SYLWIA ; Ciesielski, Witold (Springer, 2014-06-22)
; Ciesielski, Witold (Springer, 2014-06-22)
In the presented study, the content of lead in rainbow trout (Oncorhynchus mykiss) samples was examined. Rainbow trout were purchased in Prague (Czech Republic), Lodz (Poland) and Bratislava (Slovakia) from local fish shops ...
Electroanalysis of pindolol on a GCE modified with reduced graphene oxide
SMARZEWSKA, SYLWIA ; Ciesielski, Witold (Royal Society of Chemistry, 2014)
; Ciesielski, Witold (Royal Society of Chemistry, 2014)
In this work, the application of an innovative, environmentally friendly reduced graphene oxide–glassy
carbon (RGO–GC) electrode is described. Using the RGO–GC electrode, basic electrochemical
properties (such as the ...
Interactions of the Gasotransmitters Contribute to Microvascular Tone (Dys)regulation in the Preterm Neonate
; ; ; ; Chwatko, Grażyna ; ; (Public Library Of Science, 2015-03-25)
; ; (Public Library Of Science, 2015-03-25)
Background & Aims
Hydrogen sulphide (H2S), nitric oxide (NO), and carbon monoxide (CO) are involved in transitional microvascular tone dysregulation in the preterm infant; however there is conflicting evidence on the ...
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
Boruń, Agnieszka ; (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 ...
Structural analysis and corrosion studies on an ISO 5832-9 biomedical alloy with TiO2 sol–gel layers
Burnat, Barbara ; ; (Springer, 2013-11-23)
; ; (Springer, 2013-11-23)
The aim of this study was to demonstrate the
relationship between the structural and corrosion properties
of an ISO 5832-9 biomedical alloy modified with titanium
dioxide (TiO2) layers. These layers were obtained via ...
Effects of Constant Magnetic Field on Electrodeposition of Co-W-Cu Alloy
Zieliński, Marek ; ; ; ; Leniart, Andrzej ; ; (Electrochemical Science Group, 2015-03-23)
; ; ; ; Leniart, Andrzej ; ; (Electrochemical Science Group, 2015-03-23)
The paper presents a study of the effect of constant magnetic field (CMF) on the basic processes of
Co-W-Cu alloys electrodeposition. The alloys electrodeposited in the presence of CMF were more
homogeneous and smooth ...
